BMW X5 Hybrid

• World premiere of the concept car BMW Vision EfficientDynamics,

showing a further stage in the BMW EfficientDynamics development strategy. The first time a 4-cylinder diesel engine has been combined with BMW ActiveHybrid Technology in a large Sports Activity Vehicle.

• The concept study based on a BMW X5 – even as a serial production model extremely efficient and dynamic – shows the unique potential
of technology developed as part of the BMW EfficientDynamics program.
It combines BMW’s superior diesel expertise with the innovative
BMW ActiveHybrid Technology. A further increase in efficiency is achieved by means of BMW EfficientDynamics measures in the environment
of the combustion engine by optimising energy flow and aerodynamics.

• By intelligently combining a combustion engine and a generator as part
of a Mild Hybrid concept, dynamic performance and efficiency are increased to an equal degree. With the extensive deployment of measures which are in some cases ready for serial production and were in some cases specially developed for this study, there is maximum utilisation of the potential of BMW EfficientDynamics for the reduction of fuel consumption and CO₂ emission levels up to the limits of what is feasible within the
BMW X5 vehicle segment. At the same time, the study clearly shows that any additional increase in efficiency over and above the highly efficient BMW vehicles already available today can only be achieved by means of
an exponential increase in effort and expense.

• With an average fuel consumption of 6.5 litres per 100 kilometres in the
EU test cycle and a CO₂ emission level of 172 grams per kilometre,
BMW Vision EfficientDynamics is by far the most efficient vehicle of its
size in the competitive environment of the BMW X models. The significant reduction of fuel consumption and exhaust emission levels is realised having to forego BMW’s characteristic driving dynamics. In addition to acceleration (0–100 km/h in 8.9 seconds), comfort and versatility are also at the level of a large SAV – but in conjunction with the fuel consumption and CO₂ emission levels of conventional vehicles in the compact class.

Technology:

• The 2.0 litre 4-cylinder diesel engine with Variable Twin Turbo, common
rail injection of the third generation and all-aluminium gearbox
housing delivers 150 kW/204 bhp and generates a maximum torque of 400 Nm between 2,000 and 2,250 rpm. It is the first diesel in the
world with a specific power output of over 100 bhp per litre of capacity.

• BMW ActiveHybrid is based on a modular principle which allows
the integration of the best possible components in differing concepts, according to the “Best of Hybrid” strategy. The components used in
the BMW Vision EfficientDynamics study – Mild Hybrid and 4-cylinder diesel – harmonise just as perfectly as the combination of Full Hybrid and the 8-cylinder petrol engine in the BMW Concept X6 ActiveHybrid.

• The innovative hybrid system of the concept study BMW Vision EfficientDynamics reflects the most sophisticated stage of development of intelligent energy management in the vehicle to date. In the Mild Hybrid concept, the generator contributes to vehicle acceleration with 15 kW and
a maximum torque of 210 Nm. The total output of the vehicle is 165 kW.
The hybrid technology thus increases the dynamic potential of the
4-cylinder diesel engine in way which is in keeping with the character of the BMW X5, as well as enabling the combination of a small engine with
a large vehicle in the first place. What is more, the generator produces electricity to supply the power consumers in the vehicle by means of
Brake Energy Regeneration. This minimises the direct conversion of fuel into electrical energy and maximises the drive torque available for conversion into driving dynamics.

• Power generation: the compact generator, integrated in the gearbox housing, replaces a conventional generator powered directly by the engine. Electrical energy is produced by Brake Energy Regeneration with a unique degree of efficiency without impairing the drive torque of the engine. The high-power electronic system – for the first time flange-mounted directly onto the gearbox – allows a compact design which has never been possible before, as well as a sound arrangement of the hybrid components.

• Battery: a high-performance, package-appropriate lithium-ion battery integrated in the luggage compartment supplies the vehicle electrical system. Its high storage capacity enables optimum exploitation of the potential provided by Brake Energy Regeneration.

• Use of electrical power: due to the higher level of electrical power output available, additional vehicle functions can be powered purely electrically. The Auto Start/Stop Function for avoiding idling phases of the combustion engine is available virtually all the time and without any loss of comfort in conjunction with ActiveHybrid Technology.

• The hybrid module is based on a technology which was conceived as
part of the hybrid co-operation between BMW and Daimler. The hybrid co-operation successfully develops components for hybrid drives including high-power electronic systems and high-volt batteries. Here, the specific BMW design of the hybrid drive systems is ensured.

• The concept car BMW Vision EfficientDynamics is fitted with a novel,
highly efficient 8-speed automatic transmission developed jointly by
BMW and ZF Getriebe GmbH. Presented here for the first time and ready for serial production use, this 8-speed automatic transmission makes
an additional contribution to reducing fuel consumption and exhaust emissions with its direct connection to the engine and minimised torque-converter slip. The further increased shift dynamics and direct-find function for moving into the selected driving position promote a dynamic driving response. Power transmission is effected via the intelligent all-wheel
drive system BMW xDrive, i.e. fully variably between the front and rear axle.

• In the concept car BMW Vision EfficientDynamics there is also a solar
roof which acts as an additional energy source for the vehicle power supply which is independent of the engine. High-power solar cells covering
a surface area of some 1.0 square metres generate a maximum energy
of one kilowatt hour for consumers inside and outside the vehicle. This enables pre-heating of the gear oil, thereby shortening the inefficient warm-up phase. What is more, direct energy supply is possible during standstill
for ventilation or for operating a cool box, audio equipment, a mobile phone charger or for charging the vehicle battery, for example. This optimised
the availability and use of electrical energy in a way which is CO₂-neutral.

Exterior design:

• BMW Vision EfficientDynamics is based visually and technologically
on the BMW X5. The BMW ActiveHybrid components are integrated in the vehicle in a way which is appropriate to the overall package. The generator and high-power electronic system are integrated in the transmission casing and thus invisible from the outside. A specially designed load compartment recess reflects the compact design of the lithium-ion battery.

• An innovative rim design opens up additional potential in the optimi-
sation of aerodynamics. The aero wheels of the concept car BMW Vision EfficientDynamics make an additional contribution to reducing fuel consumption, for example by requiring one kilowatt less of propulsion power at a speed of 160 km/h. The aerodynamic shaping of the spokes reduces rim ventilation. This has a positive impact on the aerodynamic properties of the vehicle.

Audi TT 2.0 TDI quattro (Coupe - Roadster)

Audi is setting the pace with this synthesis of excellent dynamism and low fuel consumption, as it has done for many years: Since debuting in 1989 the TDI engines from the brand with the four rings have been paving the way for the world’s most successful efficiency technology and acting as trendsetters for the entire automobile industry. Today, these powerful, refined and highly fuelefficient engines represent a modern, smart take on sportiness. The run of victories achieved by the Audi R10 TDI diesel race car at the Le Mans 24 Hours and in the American Le Mans Series are impressive evidence of the tremendous potential of this technology.

The dynamic diesel engines from Audi exert an exciting impact not just in racing but also in series-production models—and now indeed in a sports car.

The TT Coupe quattro with the 2.0 TDI sprints from zero to 100 km/h (62.14 mph) in 7.5 seconds and achieves a top speed of 226 km/h (140.43 mph). The Audi TT Roadster, likewise equipped with Quattro permanent all-wheel drive, requires only an extra tenth of a second for the standard sprint, and continues up to a top speed of 223 km/h (138.57 mph).

Both versions serve as outstanding examples of the success of the Audi efficiency strategy, thanks to their fuel efficiency ratings of 5.5 liters per 100 km (42.77 mpg), a figure that corresponds to CO2 emissions of only 145 grams/km.

Powerful, refined and efficient: The 2.0 TDI

The new four-cylinder TDI engine (engine displacement = 1,968 cc) represents a fresh take on the all-round compelling qualities of the TDI concept. Designers of the dual-camshaft, two-liter model looked to its predecessor—the mostproduced diesel engine in the world—and expanded upon its major strengths: driving pleasure, efficiency and refinement.

The new common rail injection system is equipped with highly modern piezo injectors, whose eight-hole injection nozzles can perform up to five distinct injection sequences per cycle. This fine degree of modulation creates a modest pressure increase in the combustion chambers, resulting in a significantly reduced noise level. The system pressure of 1,800 bar allows fuel to form a fine dispersion, enabling precise, highly efficient combustion. The turbocharger is also part of a new generation and operates with adjustable vanes that allow torque to build up rapidly. The positions of swirl flaps on the intake manifold are controlled by electric motors in order to adapt the flow of air to the current load and engine speed. The geometry of the engine’s pistons has been modified, and the acoustics of the camshaft drive belt have been overhauled. Just as they did in the preceding model, two balancing shafts reduce the vibrations arising in the crankshaft drive.

The cumulative result of this progress is a high maximum engine speed of 5,000 rpm and, most importantly, improved thermodynamics in the combustion chambers. What this means is that the engine can run on up to 60 percent recycled exhaust that has been thoroughly cooled by the radiator. This results in a drastic reduction in untreated NOx emissions, with the 2.0 TDI already

meeting the threshold values of the upcoming Euro 5 standard.

Dynamic road performance

The 2.0 TDI in the Audi TT Coupe and the Audi TT Roadster delivers 125 kW (170 hp) at 4,200 rpm and sends a full 350 Nm (258.15 lb-ft) of torque to the crankshaft at engine speeds between 1,750 and 2,500 rpm. Operating quietly and generating little in the way of vibration, this model delivers a hefty amount of power at the lowest rpm levels and is highly responsive to input from the gas pedal. Its supreme power development lends this engine its own unique, fascinating character—that of a muscular, smart sports engine.

The Audi TT Coupe 2.0 TDI quattro easily leaves the gasoline-powered competition behind when accelerating from a standstill. It sprints from zero to 100 km/h (62.14 mph) in just 7.5 seconds and never looks back until it reaches 226 km/h (140.43 mph). The TT Roadster accelerates to 100 km/h (62.14 mph) in 7.7 seconds and keeps going up to 223 km/h (138.57 mph). These models—the world’s first diesel sports cars—consume an average of only 5.3 liters and 5.5 liters of fuel per 100 km (44.38 mpg and 42.77 mpg) respectively, which corresponds to CO2 emissions of a mere 140 g/km and 145 g/km. In so doing, they are setting a benchmark that represents a veritable quantum leap in the sports car segment. With the TDI engine in the TT series, Audi once again establishes its leading role on the diesel market. The brand with the four rings is advancing progress and starting at the top. In keeping with the theme of sporty performance, Audi has combined its two diesel-engine sports cars with highly effective manual six-speed transmissions whose short lever travel allows the driver to shift quickly, easily and precisely. The housings for these transmissions are made of lightweight, high-tech magnesium materials. Relatively long final transmission ratios have been employed to bring the drivetrain in line with the character of the TDI engine.

In light of their high torque values, Audi is equipping both of its new TT models with quattro permanent all-wheel drive. The heart of this system is an electronically controlled, hydraulically activated multi-plate clutch, which is located in the rear of the vehicle for improved weight distribution. This clutch generally distributes up to 85 percent of the engine power to the front axle and 15 percent to the rear axle; in extreme situations it can divert up to 100 percent of the power to either axle.

The overall concept: An exercise in uncompromised sportiness

Consistent efforts to reduce vehicle weight are also part of the efficiency strategy pursued by the brand with the four rings. Both sports cars are very lightweight: the 2 + 2-seater TT Coupe weighs only about 1,370 kilograms (3020.33 lbs) when empty, while the two-seater TT Roadster with soft top weighs roughly 1,415 kilograms (3119.54 lbs). Underlying these low weights is

an innovative hybrid body construction developed by Audi. Front components are made of aluminum and utilize Space Frame technology; rear components are made of steel. This solution guarantees that the frame is as rigid as possible and optimizes load distribution between the axles. The Audi TT Coupe and TT Roadster are dynamic, emotion-packed sports

cars. As was the case with preceding models, these cars are impressive for their powerful design, whose dynamic flow continues on into the interior. The cockpit contains multiple nods to the circle motif, and the sports steering wheel with its flat-bottomed rim fits the driver’s hand like a glove. The sport seats are deep-set, providing a sporty seated position and firm lateral support. The backs of both rear seats fold down in the TT Coupe, making the trunk space grow from 290 to 700 cubic liters (10.24 – 24.72 cubic ft). The Roadster (250 liters, 8.83 cubic ft) comes with a practical load-through hatch upon request. The sports suspension likewise offers extraordinarily dynamic features. The front suspension is pivoted on an aluminum subframe and has a wide track measuring 1,572 millimeters (61.89 inches).

A highly precise rack-and-pinion steering system with a direct steering ratio provides an intimate link between the driver and the road. Power steering with servo assist, which decreases as speed increases, is generated by an electromechanical drive that is even more efficient than a hydraulic pump. The coil springs and shock absorbers in the four-link rear axle are situated in

separate areas. The links are also finely differentiated: The layout of the trailing links, which absorb the propulsive and braking forces, is relatively soft to promote a comfortable ride. The connections to the three transverse links per wheel, on the other hand, are rigid in order to direct transverse forces into the body with precision.

The Audi TT Coupe 2.0 TDI quattro and Audi TT Roadster 2.0 TDI quattro roll on 16-inch, cast aluminum wheels fitted with 255/55 R16 tires. Behind the wheels are large disk brakes with pads that develop large coefficients of friction. The ESP stabilization program supports the neutral to slight understeering feel of the TT—the finishing touch on an overall portrait of exciting dynamics, exhilarating driving pleasure and stability you can count on.

Audi magnetic ride, a high-tech shock-absorber system available as an option, is an adaptive system that resolves the traditional conflict of interests between comfort and handling. A magneto-rheological fluid circulating in the shock absorbers changes the direction of the magnetic particles within milliseconds when electricity is applied; this alters the overall characteristics of the fluid and, in turn, modifies the damping characteristic. The driver can choose between “Normal” and “Sport” programs by flipping a switch.

Equipment makes a statement of refined style

Standard equipment for both of the new TT models reflects the sporty character and refined style of the series. Faux aluminum accents add a shine to gray inlays and various other components in the interior. The sports steering wheel comes with a Nappa leather cover. The climate control system (standard for the TT Coupe) regulates heating and ventilation in response to the level of sunlight. The driver information system and chorus audio system round out the standard equipment. A wide array of high-tech equipment is available as options, including a highly modern generation of audio devices, electrically adjustable front seats, the adaptive light dynamic cornering light system and two navigation systems with a user interface based on the Audi MMI concept—a cut above the competition.

Mercedes-Benz enters spring with five new model highlights

Mercedes-Benz is continuing its commitment to further reductions in fuel consumption and exhaust emissions with new products in five model series which will take the stage at this year’s Geneva Motor Show. Despite their outstanding levels of safety, comfort and refinement, the new coupes and roadsters consume up to 10 percent less fuel than their predecessors.

At the pinnacle of the new Mercedes dream machines celebrating their public premiere in Geneva is the SL-Class. Mercedes-Benz has refined, improved and developed the roadster further to a level of detail and extent that goes well beyond a mere model facelift. The result is a car that combines sportiness, safety and comfort into a synthesis unrivalled in this vehicle class, offering Mercedes driving refinement at sports car level.

The new, decidedly sporty and assured exterior design reflects the handling characteristics of this Mercedes roadster, which is now even more agile with a new direct-steer system while offering even more safety and comfort. Two new six-cylinder engines will round off the SL range from spring 2008: the SL 280 develops 170 kW/ 231 hp and provides an attractive entry into the SL sports car world. The SL 350 is powered by a newly developed and particularly lively sports engine. Output has increased by 16 percent to 232 kW/316 hp compared to the previous 3.5-litre engine, while maximum torque has improved by 10 Nm to 360 newton metres. This powerpack accelerates the new SL 350 from standstill to 100 km/h in just 6.2 seconds, making it 0.4 seconds faster than the previous SL 350. More output does not mean higher fuel consumption for this sports car, however: at 9.9 litres per 100 kilometres, the SL 350 is 0.4 litres more economical (NEDC) than the preceding model with 200 kW/272 hp.

The flagship models in this series continue to be the SL 500 with a V8 engine
and the twelve-cylinder SL 600. Their engines consume up to 0.4 litres less fuel per 100 kilometres than before.

The SL consolidates its substantial lead in the field of safety with bi-xenon headlamps and the optional Intelligent Light System, whose lighting functions are designed for typical driving situations. One new onboard feature is the AIRSCARF neck-level heating system invented and patented by Mercedes-Benz. This optional system improves comfort when driving with the top down, and is able to extend the roadster season into the cooler months of the year.

The front-end design of the SL-Class shows that Mercedes-Benz has enhanced the sporty attributes of the roadster even further. The centrepiece is a wide and therefore very imposing radiator grille, whose arrow shape symbolises virtues such as go-getting performance potential. A horizontal louvre adds visual width to the radiator grille and thereby reinforces the muscular appearance of the SL’s front end, which consequently seems surprisingly new yet very familiar.

SLK: even more driving pleasure with considerably lower fuel consumption

Following a comprehensive model facelift, the Mercedes-Benz SLK is now even more dynamic and provides an even more emotional driving experience. The most important visual changes include a redesigned front and rear end, as well as a carefully modified interior with a new instrument cluster and three-spoke sports steering wheel. Mercedes-Benz also installs the V6 sports engine from the SL-Class in the new SLK 350, where it develops an output of 224 kW/305 hp at 6500 rpm ‑ 24 kW/33 hp more than the six-cylinder unit in the previous SLK 350. Torque has also been increased by 10 Nm, and is now 360 newton metres at 4900 rpm.

Despite this higher output and very good performance figures, the fuel consumption of the SLK 350 has been significantly reduced. Its combined consumption with the six-speed manual transmission is now only 9.5 litres per 100 kilometres, which represents a remarkable reduction in fuel consumption by 1.1 litres per 100 kilometres.

In addition to the SLK 350, the four-cylinder model SLK 200 KOMPRESSOR and the six-cylinder SLK 280 remain available in this compact Mercedes roadster range: the output of the supercharged four-cylinder engine has increased by 15 kW/21 hp to 135 kW/184 hp, while fuel consumption has been lowered by one litre to 7.7 litres per 100 kilometres. The NEDC fuel consumption of the SLK 280 (170 kW/231 hp) has been reduced by 0.4 litres to 9.3 litres per 100 kilometres. The SLK 55 AMG continues to be powered by the familiar 5.5-litre V8 engine developing 265 kW/360 hp.

The designers have given an even more sporty touch to the visual appearance of this cult two-seater. One eye-catching feature is the newly designed front bumper, which now has differently distributed cooling air apertures and a more pronounced arrow shape. The rear end has also been restyled; the diffuser-look lower section now makes the roadster appear even more muscular from the rear. Trapezoidal exhaust tailpipes and dark-tinted tail lights do even more to accentuate this impression. The exterior mirrors now have LED indicator repeaters with a pronounced arrow shape, and also have a larger lens area.

CLC: new Sports Coupé with CDI engines in the five-litre consumption class

With the new CLC, Mercedes-Benz is presenting a distinctive model series at the Geneva Motor Show which provides an attractive entry into the Coupé family of the Stuttgartbrand. Compared to the previous Sports Coupé, Mercedes engineers have newly developed or improved more than 1100 components.

Compact body dimensions and powerful proportions underline the sporty appearance of the new CLC. The front and rear ends have been completely newly designed. With its striking coupé radiator grille, which has a large Mercedes star at its centre, as well as the new projection-beam headlamps, the Sports Coupé follows the modern Mercedes design idiom. The large, newly designed boot lid conceals a variable luggage compartment with a capacity of up to 1100 litres. The new tail lights, the long row of LEDs forming the third brake light and the rear bumper subdivide the rear end and accentuate its width.

The interior of the new Mercedes-Benz CLC is akin to a modern bespoke suit - precisely fitting and comfortable. Sports seats with further improved lateral support, a three-spoke multifunction steering wheel, automatic climate control and brushed aluminium trim are standard equipment.

Mercedes-Benz has put together a sports package for drivers with particularly sporty leanings. This includes exclusive technical innovations and extras such as 18-inch light-alloy wheels, wide-base tyres, headlamps with a black-tinted interior frame, a lowered sports suspension, a leather sports steering wheel and tinted aluminium trim. Another special feature the CLC that has been adopted from racing sports cars is the instrument cluster, which has red needles in the speedometer and rev counter. When the ignition is switched on, both needles spin right around the scale once then return to their starting position.

Another standard feature of the sports package is the new direct-steer system, which further enhances the agile handling of the CLC and represents a major safety benefit. This new development is based on the speed-sensitive steering system, and also has an additional, variable rack ratio which responds to the steering angle.

The new CLC is available with a choice of four four-cylinder and two six-cylinder engines developing outputs from 90 kW/122 hp to 200 kW/272 hp. With its
up-to-date turbodiesel engines, the Sports Coupé is right at home in the five litre fuel consumption category: the CLC 200 CDI is happy with 5.8 to 6.1 litres per 100 kilometres (NEDC), i.e. up to 10.8 percent less than the preceding model. The CDI models are capable of a range exceeding 1000 kilometres with one tankful (62 litres). The 135 kW/184 hp power unit of the CLC 200 KOMPRESSOR now has 15 kW/20 hp more output, and consumes only 7.8 to 8.2 litres per 100 kilometres (NEDC) - up to 0.7 litres less than before.

CLS: new six-cylinder engine and fine-tuning to the last detail

The unique, four-door CLS Coupé - which pioneered a new automotive segment - has also been made more attractive than ever by specific fine-tuning. The front aspect is dominated by a modified radiator grille, which now has two rather than the previous four louvres. The exterior mirrors also have a new shape, with integrated, arrow-shaped LED indicator repeaters and more than 30 percent larger lenses. The tail lights are now also in LED technology: the brake lights, rear lights and indicators feature particularly fast-responding light-emitting diodes.

Great attention to detail has also been lavished on the updated interior: a newly designed leather steering wheel with three spokes and multifunction buttons is part of the package, as is a new-look instrument cluster, whose white dial faces form an attractive contrast to the structured surface of the backplate. New chestnut wood inserts replace the previous trim.

Like the SL, SLK and CLC, the CLS benefits from new-generation infotainment systems. These high-performance units combine ease of operation and intuitive menus with perfect entertainment. Features include speed-sensitive volume control, a keypad for entering telephone numbers and radio frequencies, an MP3-capable CD and DVD player and a Bluetooth interface which wirelessly connects a mobile phone with the onboard hands-free system. Audio 20, Audio 20 CD with CD changer, Audio 50 and Audio 50 APS with DVD changer and the LINGUATRONIC voice-control system now feature a 5-inch colour monitor. COMAND APS has a high-resolution 6.5-inch colour display, LINGUATRONIC for audio, navigation and telephony, a music register for storing audio files and an SD memory card slot.

As the new entry-level model, Mercedes-Benz now offers the CLS 280 with an up-to-date 2996 cc V6 engine, a maximum output of 170 kW/231 hp and a maximum torque of 300 newton metres. Its combined NEDC fuel consumption is 9.8 to 10.0 litres per 100 kilometres. The second V6 petrol model is the CLS 350 CGI. Its advanced six-cylinder engine with piezo-electric direct injection and a spray-guided combustion system develops an output of 215 kW/292 hp and has a convincingly low NEDC fuel consumption of 9.1 to 9.3 litres per 100 kilometres.

The CLS 500 is powered by a V8 engine with a displacement of 5.5 litres and a peak output of 285 kW/388 hp. The CLS 320 CDI with its 165 kW/224 hp V6 diesel engine above all excels with its high torque of 540 newton metres, accompanied by a low diesel fuel consumption of 7.6 to 8.1 litres per 100 kilometres. All CLS models are equipped with the 7G-TRONIC seven-speed automatic transmission as standard.

CL: permanent all-wheel drive with no fuel penalty

The Mercedes Coupé family continues to be headed by the luxurious CL-Class, which offers the widest model range in this vehicle class with the CL 500, CL 600, CL 63 AMG and CL 65 AMG. In addition Mercedes-Benz will be entering the lists with the new CL 500 4MATIC with permanent all-wheel drive from summer 2008. This two-door model is equipped with a 285 kW/388 hp V8 engine, and in addition to 4MATIC it features innovations such as the Intelligent Light System and the preventive occupant protection system PRE-SAFE® as standard.

Mercedes-Benz has further improved this all-wheel drive system, and uses the latest-generation system in the CL 500 4MATIC - the one that has already proved successful in the S-Class. 4MATIC is permanently active and therefore requires no response time to assist the driver in infavourable weather and driving conditions. As a result, critical situations can be mastered better and more confidently.

With a weight of just 70 kilograms, the newly-developed 4MATIC is the lightest drive system of its kind. The combined NEDC fuel consumption of the CL 500 4MATIC is 12.1 litres per 100 kilometres, which puts it at the same level as the CL 500 with rear-wheel drive – another advantage of the new, highly efficient Mercedes all-wheel drive system. The CL 500 4MATIC requires just 5.4 seconds to accelerate from zero to 100 km/h, and reaches an electronically limited top speed of 250 km/h.

Audi A4 Avant

Dynamic, elegant, and emotional; with the A4 sedan, Audi has already advanced into a new dimension. In a few weeks, the A4 Avant will follow: The most successful premium station wagon of its class offers, along with excellent drivability and uncompromising quality, a higher utility value for sports and recreation. This vehicle combines elegance and intelligent functionality.

The Audi A4 Avant is extending its lead. Based on the same technology layout as the sedan, the newly developed five-link front axle has been shifted farther forward. This ensures that the axle loads are perfectly distributed, thereby guaranteeing the highest precision and agility when it comes to handling. The Avant therefore also offers a new and fascinating driving experience similar to the one that led media experts to pronounce the sedan the best automobile in the midsize range.

Audi is launching the A4 Avant with five engine types to begin with: two gasoline engines and three diesel engines. These engines offer superior performance while reducing fuel consumption by more than 14 percent compared to the previous model – proof of Audi’s successful efficiency strategy.
Audi’s high technological competence is also expressed in the broadly diversified range of powertrains and in its numerous sport and comfort technologies – many of which originate directly from the premium class.
The design of the new Audi A4 Avant is as exciting and dynamic as one would expect from a brand as design-oriented as Audi. The headlights are staged like a technological work of art. The Avant comes with daytime running lights as a standard feature; the xenon plus headlights consist of 14 white light-emitting diodes.
Compared to the forerunner model, the proportions have been reconfigured in a new and even sportier design. The front overhang has been shortened, and the engine hood and the wheel base have gained considerably in length. The flat D-posts lend the Audi A4 Avant a dynamic, coupe-like silhouette, while the rear design emphasizes its width with powerful, horizontal lines. The new A4 Avant measures 4.70 meters (15.42 feet) in length, almost 12 centimeters (4.72 inches) longer than its forerunner model. Its body is considerably more rigid and safer in build than its predecessor, yet is around 10 percent lighter at the same time.
With up to 1,430 liters in volume (50.50 cubic feet), the latest addition to the Audi family has the largest luggage capacity in its competitive field; in its basic configuration it holds 490 liters (129 gallons). The 60/40 split-fold rear seats also come with the option of a load-through hatch with separate ski and snowboard bag. The A4 Avant’s trunk is lined with fine carpet and features intelligent details as standard such as a reversible cargo floor and a convenient cargo cover that retracts at a touch. Audi also offers luxury features such as an electro-mechanical drive for the rear tailgate or tie-down eyelets for securing luggage.
The ambience inside the new A4 Avant is light and spacious. The interior reflects Audi’s strengths – the highest quality of workmanship, sophisticated looks, and logical, intuitive operation. The cockpit is driver-oriented; it borrows many features from the larger A8. Thanks to the new electro-mechanical parking brake, the manual parking brake was no longer necessary.
Even the standard climate control system has been completely redesigned. It supplies ten percent more cooling capacity, yet operates more efficiently than the previous system, thus saving about 0.2 liters of fuel per 100 km.
When it comes to safety, Audi has raised the bar, for example, with its combination of adaptive airbags, belt tensioners with variable belt force limiters and seat position sensors on the front seats. With this system, the force of the airbag deployment and belt tension level are selectively controlled depending on the seat position and the accident severity. In case of a rear-end collision, the backs of the front seats and the head rests support the upper body. This system is called Audi backguard and has received special praise during independent tests.
The new Audi A4 Avant will be launched on the market with two powerful gasoline engines and two diesel engines, thus covering a range of 105 kW (143 hp) to 195 kW (265 hp). The 2.0 TDI generating 125 kW (170 hp) will be added later to round out the range. All the engines have FSI and TDI direct fuel injection technology and the three four-cylinder engines reach high torques thanks to turbocharger technology. On average, the engine performance in this model series has increased by almost eight percent. At the same time, fuel consumption in the gasoline engines has dropped by almost 12 percent, and the TDI engines by almost nine percent.
The new 3.2 FSI is the most powerful engine that comes with the new A4 Avant. It has an output of 195 kW (265 hp) and reaches 330 Nm (243.40 lb-ft) of torque between 3,000 and 5,000 rpm. Enhancements to the V6 include considerably lower inner friction and a valve actuation system called the Audi Valvelift System, which varies the stroke of the intake valves.

The 3.2 FSI delivers sport-driven performance in any situation. It powers the A4 Avant from zero to 100 km/h (62.14 mph) in just 6.4 seconds and on up to a top speed of 250 km/h (155.34 mph). At the same time, fuel consumption has dropped by 1.5 liters (0.40 gallons) compared to its predecessor.

The 1.8 TFSI, too, is a highly efficient engine. The compact and light four-cylinder unit has an output of 118 kW (160 hp) and reaches 250 Nm (184.39 lb-ft) of torque between 1,500 and 4,500 rpm. Direct gasoline injection and turbocharging create the ideal combination in this model. The 1.8 liter engine responds spontaneously and provides a highly refined driving experience. It powers the car from zero to 100 km/h (62.14 mph) in 8.9 seconds and on up to a top speed of 218 km/h (135.46 mph).

The 3.0 TDI engine in the Audi A4 Avant comes across as a widely new engine, particularly when it comes to the fuel injection system and the turbo. This three liter diesel unit, which is firmly coupled to the manual transmission, has an output of 176 kW (240 hp) and reaches a torque of 500 Nm (368.78 lb-ft) between 1,500 and 3,000 rpm. Its performance figures – from zero to 100 km/h (62.14 mph) in 6.3 seconds, a top speed of 250 km/h (155.34 mph) – demonstrate this engine’s dynamic character.
The 2.0 TDI has a new common rail fuel injection system that guarantees refined running; other innovations include the turbo and the piston geometry. Audi offers the two liter diesel engine in two versions: one developing 105 kW (143 hp) and 320 Nm (236.02 lb-ft) of torque and the other generating 125 kW (170 hp) and 350 Nm (258.15 lb-ft) of torque. Both ensure powerful propulsion – the basic TDI accelerates the A4 Avant to 100 km/h (62.14 mph) in 9.7 seconds and facilitates a top speed of 208 km/h (129.25 mph). The more powerful of the two accelerates the Avant to 100 km/h (62.14 mph) in 8.6 seconds and on up to a top speed of 222 km/h (139.19 mph).
When it comes to power transmissions, customers can choose from a broad range of high-tech components. Six-speed manual and tiptronic transmissions (optional for the 3.2 FSI) transfer the engine’s torque. For the 1.8 TFSI unit and the 2.0 TDI engine generating 105 kW (143 hp), the continuously variable multitronic transmission is also an option.
The 3.2 FSI and the 3.0 TDI come equipped with quattro permanent all-wheel drive as a standard feature. It distributes the forces under normal driving conditions at a ratio of 40 : 60 between the front and rear axle – a configuration that perfectly harmonizes the overall dynamic character of the new A4 Avant. If needed, the Torsen differential transfers the majority of the torque to the axle with the better traction.
In the driveline of the new A4 Avant, the differential has moved directly behind the engine. It has switched places with the clutch or the torque converter.
It was therefore possible to move the front axle 154 millimeters (6.06 inches) forward. This solution provides for a longer wheel base and for the perfect distribution of the axle loads, thus improving both handling and ride comfort equally.
The dynamic suspension of the new Audi A4 was redesigned from top to bottom. The pivot bearing and the five links of the front axle are also made of aluminum, just like the beam, which makes the front end of the body more rigid. The steering box is located far to the front and deep down to enable the steering impulse to go directly to the wheels via the tie-rods. The highly efficient servo pump in the sensitive rack-and-pinion steering improves fuel consumption by about 0.1 liter/100 km.
In the rear axle, Audi applied the track-controlled trapezoidal link principle from the larger A6 and A8 series. The suspension is made largely of aluminum; the separate layout of the springs and shock absorbers guarantees sensitive responsiveness. The new A4 Avant will roll off the production line on 16 inch and 17 inch alloy wheels, behind which are located powerful brakes. The electronic stabilization program (ESP) can be partially switched off when driving under 70 km/h (43.50 mph).
A package of innovative technology makes the driving experience even more dynamic and exciting. The optional Audi drive select control system accesses various technology components, depending on which upgrade the customer has selected. In the basic version, it influences the engine’s gas intake, the tiptronic shifting points, the multitronic and the power steering as well as the steering angle of the steering wheel. By pressing a button, the driver determines whether these components should work in a comfortable, average or sporty mode. If the car is equipped with the MMI operating system, a fourth, individually programmable mode is available.
Audi drive select requires at least one of the following two high-end components. One is an adaptive controller for the shock absorbers which is connected to a sports suspension and lowers the body by about 20 millimeters (0.79 inches).
The second component is the Audi dynamic steering that operates with a superposition gear. It varies the steering ratio continuously by almost 100 percent depending on the speed driven. In the limit range, it stabilizes the new A4 Avant thanks to its lightning-fast steering interventions. The system is also extremely useful when understeering occurs.
Audi equips the new Avant, upon request, with a complete range of high-tech systems that make driving an even more supreme and relaxed experience. These include the Audi parking system (a parking aid; standard for the A4 Avant Ambiente), Audi lane assist (the lane departure warning system) and Audi side assist (which warns of hazards when changing lane). Adaptive cruise control maintains the distance to the vehicle in front.
Even when it comes to multimedia, the Audi A4 Avant sets new standards. The Audi Music Interface (AMI) allows iPods to be connected. The navigation systems with MMI Basic plus or with DVD including MMI are also further upgrade options. They permit the integration of cell phones as Bluetooth car phones and are combined with the competition-beating MMI operating system. The top of the line when it comes to hi-fi enjoyment is the car’s sound system from the leading Danish company Bang & Olufsen: A powerful 505 watt, ten-channel amplifier controls 14 speakers.
The new Audi A4 Avant will roll off the production line in the Attraction, Ambition, and Ambiente equipment lines. The dynamic S line offers the options of an exterior package and a sports package. The broad range of options includes luxury-class features such as air-conditioned comfort seats, the triple-zone climate control system, the advanced key which allows keyless access to the vehicle and vehicle start-up at the press of a button, and the dynamic cornering light system known as adaptive light. The large panoramic glass sunroof lights up the elegant interior. A new headlight assistant will be an additional feature in the future.
The A4 Avant will be available for sale in the spring in Germany and other European markets. The basic price of the Audi A4 Avant 1.8 TFSI Attraction model with an output of 88 kW (120 hp) will be €27,550 and it will be available in the fall.

Chrysler ecoVoyager Concept

Elegant luxury design coupled with advanced hydrogen fuel cell Range-extended Electric Vehicle technology Chrysler's concept for 2008 – the ecoVoyager – marries an elegant American design with fuel cell Range-extended Electric Vehicle technology.

"The 2008 Chrysler ecoVoyager concept vehicle celebrates the romance of automobile travel embodied in a four-door, four-passenger, distinctively American automobile of spirited design," said Greg Howell, principal ecoVoyager concept exterior designer. "While the ecoVoyager's supple, flowing one-box shape is purposely designed to achieve aerodynamic efficiencies, it also pushes the Chrysler brand language in a new direction of 'elegant simplicity,' by taking full advantage of the space normally occupied by a bulky conventional powertrain setup to drastically reduce the front overhang."

Featuring crisscrossing forms defined by hard lines with fluid intersections, the style vocabulary of the ecoVoyager embodies Chrysler's harmonization of functional technology with beautifully-styled exteriors and interiors.

The Chrysler ecoVoyager concept was developed for customers wanting a travel experience on par with a private jet, but without a lot of fancy gadgetry. These customers seek three critical attributes: elegance, simplicity and serenity.

Chrysler ecoVoyager Concept Technology

The all-new Chrysler ecoVoyager's wheels are driven by an electric motor, with power primarily supplied by a lithium-ion battery pack capable of satisfying a consumer's typical daily commute of less than 40 miles.

The electric motor develops 200 kilowatts (268 horsepower), enabling acceleration from 0 to 60 mph in less than eight seconds. A regenerative braking system captures energy that would normally be lost and returns it to the battery, making the Chrysler ecoVoyager concept a very efficient and spacious vehicle.

The ecoVoyager takes advantage of a range extender – in this case, a small, advanced hydrogen fuel cell -- to extend the vehicle range for occasional long trips. With this advanced technology, the Chrysler ecoVoyager's total range is greater than 300 miles, while no emissions – besides water vapor -- come from the tailpipe along the way.

With the entire propulsion system located below the ecoVoyager's floor, space is maximized for utility of passenger and cargo.

Chrysler ecoVoyager Concept Exterior

Expressive details of the Chrysler ecoVoyager concept include panoramic roof glass bisected by a center spine, tight body overhangs and a dramatic boat-tail back end. The sinuous shapes of the window graphics, headlamps, taillamps and grille openings are inspired by Chrysler's storied winged badge.

The curving trapezoidal shape of the ecoVoyager's grille is echoed by the clear lens-covered shadow box that houses the rear license plate. The sloping backlight features a similar shape, emphasizing the repeating harmony of the ecoVoyager's design elements.

Other exterior touches on the Chrysler ecoVoyager concept include the elongated, flaring "light catchers" on the lower doors and the front and rear fascias, enhanced by the Polar Ice exterior color.

Finally, side doors open a wide 90 degrees. Since the rear doors are hinged at the rear and there is no center B-pillar, entrance into the ecoVoyager is virtually unimpeded.

Chrysler ecoVoyager Concept Interior

By placing the front wheels of the Chrysler ecoVoyager concept farther forward than usual, designers were able to create greater interior roominess and increased legroom, especially in the rear seats.

In the ecoVoyager's spacious interior, the size, design and location of all controls have been rethought to provide its four pampered passengers the luxury of having every feature within effortless reach.

"In some ways, true luxury is in not having to reach or search around for controls," said Ty Stump, principal interior designer of the Chrysler ecoVoyager concept. "With the new ecoVoyager concept, we carefully placed the gauges and controls in order to reduce head and eye movement. We also achieved simplicity in the interior forms, both for visual elegance and to avoid distracting surfaces."

The ecoVoyager's windshield defroster and cabin air-conditioning outlets in the instrument panels and doors, for example, are invisible beneath a recessed perforated mesh. This avoids visually-disruptive array sliding vanes and protruding knobs. Even the color of the interior -- soft Dove Gray with warm cherry wood accents - is designed to promote a relaxed ambiance.

The Chrysler ecoVoyager's unconventional instrument panel features a broad, leather-covered angled surface, slightly V-shaped in plan view and fronted by a full-width display screen set just below the windshield. The left and right outer ends of this non-glare screen contain the side-view mirror image, while a third camera image in front of the driver serves as the rearview mirror.

Unlike most instrument clusters, only currently-needed information is displayed, designed to be viewed above the steering wheel rim rather than through it (and requiring less up-down eye movement and refocusing). The front-seat passenger can view a movie without its moving images disturbing the driver. A slick, slide-out/retractable center console – fitted with hot-key buttons and a mouse pad – replaces the functions contained in a conventional vertical center stack.

The ecoVoyager's four individual chairs are contoured for personalized comfort. The seat framing is exposed, with under-seat storage drawers. Front seats have individual cantilevered, adjustable armrests containing the window controls and heat/massage switches, while individual rear-seat armrests fold into the cabin back panel. With the ability to store six 20-ounce bottles, the floor console dividing the rear seats accommodates hot or cold beverages.

A recessed area in the headliner between the two longitudinal skylights contains the "Direct Sound" function. With this feature, the musical entertainment choice of each individual occupant can be directed to him or her without the use of headphones, and without disturbing others in the car.

Sleek, refined, efficient and superbly comfortable, the Chrysler ecoVoyager concept vehicle offers a new experience in stress-free travel.

Volvo XC60

Here are the first pictures of one of this year's most exciting new car models - the new Volvo XC60! "It's not only the safest Volvo ever. If you ask me, it's also the most stunning. Not a bad combination, is it?" says Volvo Cars President and CEO Fredrik Arp. The new XC60 has its premiere showing at the international car show in Geneva on March 4 and the first cars will reach dealers in Europe in autumn 2008.

Volvo Cars' new crossover steps boldly into what is the motoring world's toughest and fastest-growing segment, boasting an exciting mix of two car styles. Down below, the unmistakeable, capable XC muscles are pumped up, creating a strong athletic body mated with high ground clearance and large wheels. Up above, the flowing lines create the sporty charisma of a coupe.

"This car is charged with more emotive form and more energy than any other Volvo. We're elevating our design DNA to an entirely new level by literally turning up the visual volume. If you say that you'd recognise a Volvo from a hundred metres away today, I dare say the XC60 radiates a clear Volvo presence from at least twice that distance," says Volvo Cars Design Director Steve Mattin.

A variety of intelligent safety systems are another important part of the XC60 model's special character. The big news is City Safety - a unique feature that can help the driver avoid or reduce the effects of the type of low-speed impacts that are common in city traffic and traffic tailbacks. If the car is about to drive into the vehicle in front and the driver does not react, the car brakes itself.

"We are the first manufacturer in the world to offer this type of feature as standard. City Safety clearly advertises that the new XC60 is the safest car Volvo has ever produced. The car is packed with our accumulated safety know-how and technology, both when it comes to preventing accidents and protecting all the occupants in a collision," says Fredrik Arp.

The XC60 project has its sights set on a target group that imposes high demands on design, brand integrity and high-tech content in its choice of lifestyle products.

"One might say that this could be the C30 owner's next car. It's as sporty and exciting, but way more capable. With the XC60, we're widening our model range to attract even more customers with an active urban lifestyle," explains Fredrik Arp.

Equal volumes to Europe and North America

The new XC60 is being launched with a choice of three engines: the turbocharged T6 which produces 285 hp, and two variants of the D5 turbodiesel, producing 185 and 163 horsepower respectively. All Wheel Drive (AWD) is fitted as standard.

"During 2009, we will offer a front-wheel driven 2.4-litre version powered by a Euro 5 diesel engine producing 163 horsepower and with a CO2 rating of around 170 g/km," reveals Fredrik Arp.

The sales target for the new XC60 is over 50,000 cars per year. The five largest markets during peak year 2010 will be the USA, Germany, Great Britain, Russia and China.

The Volvo XC60 will be built at the Volvo Cars factory in Ghent, Belgium. Sales of the car will start in Europe during the second half of 2008, while sales in North America will get under way in early 2009.
