Mercedes-Benz SLR

Mercedes-Benz and McLaren are adding the crowning glory to the model family of their highly successful SLR super sports car with a new, uncompromisingly spectacular car. There is neither a roof nor a windscreen to separate the driver and passenger from the outside world; they enjoy unadulterated high-speed excitement with all the attributes of a speedster. The new SLR Stirling Moss is also characterised by the most sophisticated technology and a breathtaking design which reinterprets the SLR legend. With 478 kW/650 hp the SLR Stirling Moss accelerates its V8 supercharged engine from standstill to 100 km/h in less than 3.5 seconds, and has a top speed of 350 km/h – no other series-production car is at the same time so open and so fast. This extreme concept makes the new high-performance sports car a legitimate bearer of the name of the British motor racing legend and Mille Miglia record-holder Stirling Moss, who drove the legendary Mercedes-Benz SLR racing cars from victory to victory in 1955. The exclusive SLR Stirling Moss rounds off the current SLR family and is limited to 75 units. It is priced at 750,000 euros. The SLR Roadster will cease to be manufactured at the end of May 2009 as planned, and production of the SLR Stirling Moss will commence in June 2009.


Three letters are all it takes to make car fans’ hearts beat faster: SLR. In the 1950s the Mercedes-Benz SLR 300 celebrated victory after victory. It won the Mille Miglia, the Eifel race, the Targa Florio as well as the Tourist Trophy. It was driven by the stars of the time: Juan Manuel Fangio and Karl Kling – and, first and foremost, by the British racing driver Stirling Moss. At ten hours, seven minutes and 48 seconds he still holds the Mille Miglia record. This is why the modern-day version of the legendary SLR carries the additional words “Stirling Moss” in its name. As the new SLR Stirling Moss unites the character of the current SLR models with the fascination of the SLR of 1955. The core values of both the historical and the present-day SLR models include an exciting new design, innovative technology, high-class materials displaying perfect craftsmanship, and, above all: a unique driving experience for all the senses.

Remaining totally true to the specifications of the 300 SLR, the new Silver Arrow’s equipment is extremely sophisticated and yet at the same time decidedly puristic, doing without both a roof and side windows. There are just two wind deflectors a couple of centimetres in height to protect the driver and passenger from the airflow. Two air scoops integrated into the bodywork serve as roll-over bars. With this extreme concept the new SLR Stirling Moss is visually very different from all the other vehicles which belong to the elite sports car class.

Just like the legendary racing vehicles of yesteryear, the SLR Stirling Moss dazzles with its superlative performance. Accelerating from zero to 100 km/h in less than 3.5 seconds and with a top speed of 350 km/h this puristic high-performance sports car denotes completely new dimensions in open-top driving. And not just because of the impressive performance figures; every time drivers take to the wheel of the SLR Stirling Moss their senses are addressed with a previously unheard of intensity, conveying a driving experience in its purest and most sensual form. This automotive thoroughbred thus facilitates the kind of open-air feeling that is utterly unique for a road-going vehicle.

The SLR Stirling Moss, its entire bodywork made of lightweight carbon fibre, represents a stand-alone design concept. Whilst the Mercedes-Benz designers were working on the body of the new SLR Stirling Moss, they were fully aware every single moment that they were creating a vehicle with a top speed of 350 km/h. At the same time this supreme athlete is highly reminiscent of the SLR racing cars from the 1950s, whose design idiom still never fails to impress to this day.

The SLR Stirling Moss sports an exciting, pronounced arrow-shaped form and is characterised by an elongated bonnet and a compact, muscular rear. As there is no windscreen, the exterior and interior flow smoothly into one. The bonnet also stretches from its striking tip right down into the interior, giving the vehicle body a distinctly sleek air. Even when standing still, the sports car radiates such dynamism that the observer immediately falls under its spell.

Further eye-catching features include two air scoops behind the driver and passenger. They carry additional roll-over bars, also uniting the traditional and the modern. The wings are powerfully contoured. Black-painted ventilation “gills” sitting facet-like on the sides and on the bonnet also cite the legend. A thrilling interplay of light and shadow ensues through the expressive lines, underlining the dynamic overall impression. Exactly as they were on the shining historical example, the side skirts on the new SLR Stirling Moss are also very high. This prompted the designers’ decision in favour of folding swing-wing doors which open forwards.

The vehicle can be closed by two tonneau covers which are carried in the boot. When both tonneau covers and the doors are closed the SLR Stirling Moss resembles a sculpture.

In keeping with the puristic exterior of the vehicle, the interior is also reduced to the bare essentials. Surfaces penetrating each other in the instrument panel and doors make for an exciting atmosphere and resonate perfectionism. A mixture of high-class authentic materials such as carbon fibre, aluminium and fine-quality leather sets the style here. An aluminium plate carries the engraved signature of Stirling Moss and covers the area around the shift lever.

Mazda3

The new Mazda3 is perfectly positioned for the rapidly changing auto market. It offers a mix of quality, styling, power, dynamics and fit and finish that hits the bulls-eye for today’s customers. In typical Mazda fashion, Mazda3 will offer standard and optional equipment simply not found on other cars in this class – exactly what buyers looking for more value and less bulk want.

This 2010 edition stands on tall shoulders: the first-generation Mazda3 earned 90 major awards from expert critics and achieved a 1.8-million sales volume during its five years serving customers all over the world. One in three Mazdas sold is a Mazda3. Even at the end of its build life, the first-generation Mazda3 continued to earn accolades as a leading consumer magazine recently named this car as one of the most reliable compact sedans money can buy.

Mazda3 Program Manager Yoshiyuki Maeda established ambitious goals for Mazda’s most popular car line, “We were determined to advance the Zoom-Zoom driving experience to new heights because that unique feeling lies at the very heart of Mazda. On the heels of the original Mazda3’s success, we aimed to again exceed the expectations of customers all over the world by a wide margin. This meant providing drivers with a sense of exhilaration whether they were in motion, seated in the Mazda3’s cockpit, or enjoying its appearance from outside.”

On what it takes to develop a true “world car,” Maeda added, “The development process began with careful study and identification of what features and performance qualities would be needed. That initial phase ended with my conclusion that every driving characteristic was eligible for improvement to reach our Zoom-Zoom goals. Mazda engineering and R&D departments in Japan, Europe, and the US all contributed to the Mazda3’s renewal effort and the development of the company’s new world car.”

Inside, the new Mazda3 offers a sporty yet highly refined cabin. As if taut muscles lie within, the dash sweeps dramatically from its center to the cabin’s sidewalls. The large gauge cluster and center stack are positioned to tightly link the driver’s limbs and senses to the car’s instruments and controls.

The slant of the instrument panel optimizes operating efficiency while providing an attractive focal point. Range of motion studies helped position all controls at an ideal reach. Key knobs and switches are positioned at the same level as the steering wheel and the shifter. The Interior of the 2010 Mazda3 is based on our Human Machine Interface concept.

All the information a driver needs is readily available in one concentrated area that minimizes lapses of concentration on the road ahead. A Multi-Information Display is positioned high on the center portion of the instrument panel to further minimize distraction. Navigation, audio, and trip computer information is provided in this handy and easy-to-view location.

Front seat cushions have been extended by nearly an inch compared to the outgoing car in order to provide improved thigh support. Backrests are 1.4-inches taller and recontoured for improved driving posture. For the higher grade models, the upper side bolsters have been canted inward for heightened torso restraint during aggressive cornering. A three-position memory function has been added to cars equipped with power seats – another first for the segment, and not offered at any price on any competitors’ compact car. Upon approach to the car, the left-front seat automatically adjusts to the settings chosen by up to three different drivers by recognizing the code of the key fob.

To provide a top-quality cockpit appearance, the number of parting lines is minimized and soft-touch surfaces show an elegant grained texture. An interactive lighting system enhances the cabin’s ambience and sense of tranquility. Upon entry, illumination rises in intensity in a programmed manner. Occupants are welcomed by foot-well and door-handle lamps. Next, instrument cluster, center stack, audio and climate controls brighten. When a driver or front seat occupant touches an audio or AC switch, a change in illumination acknowledges that the command has been received.

Dual-zone automatic air conditioning is an available Mazda3 option. Other special features that distinguish this car from mundane compact sedans are: a Bose 10-speaker premium surround sound system, connectivity for cell phones and portable media players, a dock for iPods, and Sirius satellite radio. An advanced keyless entry system includes push-button engine starting. The Mazda3 options list also includes rain-sensing wipers, heated side mirrors, leather upholstery, and heated seats.

Overall, the details included in the new Mazda3 all contribute to the sense of quality in the car. This is a vehicle that offers equipment, fit and finish simply not found in other vehicles in this price range and class, and helps perfectly position Mazda3 for buyers considering a way to spend less and get more in this new economic climate.

The MZR 2.0-liter four-in-line engine delivers 148 horsepower at 6500 rpm (PZEV = 144 @ 6500 rpm) and 135 lb-ft of torque at 4500 rpm (PZEV = 132 @ 4500 rpm). Aluminum block and head construction saves weight. In the interests of power and efficiency, four valves per cylinder are operated by dual overhead camshafts.

The new MZR 2.5-liter four-cylinder engine is borrowed from the larger all-new 2009 MAZDA6. It shares the same construction features of the 2.0-liter engine while upping output to 167 horsepower at 6000 rpm (PZEV = 165 @ 6000 rpm) and 168 lb-ft of torque at 4000 rpm (PZEV = 167 @ 4000 rpm). Both engines employ advanced electronic throttle actuation. Mazda’s exclusive torque base control technology provides a highly linear acceleration response to every change of throttle pedal pressure.

A slick-shifting five-speed and six-speed manual transmission as well as a five-speed electronically controlled Sport-AT automatic transmission are available depending on the model. Sport-AT offers enthusiastic drivers the control of manual gear engagement with the convenience and comfort of a conventional automatic.

Fuel economy is exemplary and was key to the vehicle’s development. The Mazda3 with 2.0-liter engine achieves 25 mpg in city driving with the manual transmission and 24 mpg with the automatic. The highway mileage with the 2.0-liter engine is 33 mpg with either transmission. The Mazda3 with 2.5-liter engine also tops 20 mpg in all conditions. Equipped with the six-speed manual transmission, its city rating is 21 mpg, rising to 22 mpg with the 5-speed automatic. The highway rating is 29 mpg with either transmission. As the new Mazda3 is larger in every dimension – meeting the requests and needs of customers – Mazda engineers worked hard to deliver a vehicle that offers fuel economy on-par with the outgoing car.

To refine the acoustic qualities of the Mazda3 powertrains, extra attention was paid to tuning each engine’s intake and exhaust system. Resonance chambers were implemented to quiet certain sound frequencies while reinforcing others, achieving a well mannered yet sporty voice during acceleration. The Mazda3 2.5-liter engine is equipped with dual tailpipes and specially tuned mufflers to reduce mid-range boom and objectionable high-frequency noise at high rpm.

Mazda3s certified to U.S. Federal exhaust emission standards are equipped with catalytic converters employing advanced single nanotechnology. It is used to embed individual particles of precious metals, which are less than five nanometers in diameter, into the catalyst base material. This new development enables Mazda to reduce the amount of expensive precious metals such as platinum and palladium by 70 to 90 percent without impairing catalyst performance. The catalyst is an important part of Mazda’s efforts to reduce reliance on limited resources.

The 2009 MAZDA6 offers one of the stiffest unibody structures on any Mazda vehicle. Lessons learned in developing that car provided major strides in structural stiffness in the new Mazda3. A stiff unibody provides a smoother ride, more confident handling, and improved agility with virtually no increase in unibody weight.

Reengineered unibody joints and increased metal gauges in key areas help diminish the transmission of road and powertrain noise into the passenger cabin. Suspension anchor points are more substantial to provide the solid foundation needed to absorb steering and suspension forces. In addition to welded attachments, suspension towers are bonded to the surrounding unibody areas with structural adhesives. A combination of welding and adhesives – also borrowed from the 2009 MAZDA6 – is also used to increase the rigidity and collision deformation resistance at door opening locations. The stiffer door design also improves the effectiveness of weather seals that block moisture and noise from the interior.

A Mazda engineering approach called Aero Flow Management was used to optimize the flow of air around and through Mazda3 body openings. Even though the front grille appears larger than before, it’s actually 20-percent smaller to ingest only the amount of air needed for combustion and cooling. An air guide attached to the front bumper directs the flow through the radiator where it’s most useful. At high speeds, a bypass flap opens to minimize cooling fan drag.

Air flow along the Mazda3’s body sides was improved during wind tunnel testing by placing deflectors near the tires and by carefully tuning the upper-forward corners of the cabin. Subtle refinements in the shape of the A-pillars, exterior mirrors, windshield wipers, and taillamps also contributed to the six-percent reduction in wind noise levels. The 0.29 drag coefficient (Cd) achieved by Mazda engineers is one of the lowest available in the compact class and highly beneficial to highway fuel economy.

There was no need to reinvent the Mazda3’s chassis design because the first generation achieved distinction as the best available in the compact class in terms of driving enjoyment, handling, and all around poise. Subtle and tuning changes were the order of the day.

A rubber-isolated subframe in front supports the entire powertrain, the rack-and-pinion steering system, and the lower attachments of the coil spring MacPherson strut suspension. The independent multi-link rear suspension also uses coil springs with one trailing arm, two lateral links, and one toe-control link per side. Four-wheel power disc brakes with vented rotors in front and solid rotors in back are standard equipment. Dynamic Stability Control and Traction Control are available on all Mazda3s, standard on some trim levels.

To improve steering feel, the electro-hydraulic-assist rack-and-pinion steering gear is now secured at three instead of two attachment locations. The additional mounting point allowed a reduction in the stiffness of the bushings that support the steering gear to diminish the vibration transmitted over rough pavement.

Resistance to body roll has been increased by recalibrating the monotube rear dampers for tighter control and by switching to a new more substantial mounting arrangement for the front and rear anti-roll bars. At the front of the new Mazda3, lower control arms, the subframe, and mount bushings are all stiffer to improve both steering response and cornering grip at the adhesion limit. A redesigned rear suspension crossmember is both lighter and significantly stiffer, also for improved handling.

The most notable change to the braking system is a new vacuum booster that provides a more reassuring response to light pedal efforts without disturbing the highly direct and linear feel inherited from the first-generation Mazda3. Adjustments to the electronic brake force distribution programming enhance vehicle stability during mixed braking and cornering maneuvers. Structural changes to the unibody mentioned above help improve not only the rigidity of the brakes but also their linearity during high-g stops.
