Stuttgart - In the mid-fifties, Mercedes-Benz SLR reached a statusunico in the world of motor racing. In addition to the long list of legendary sports victories, the latest technology and attractive design this car turned in a symbol for all Gran Turismo High Performance. The new Mercedes-Benz SLR McLaren Roadster, which celebrates its world premiere in the fall of 2007, has the same charisma and the same futuristic technologies. Like the modern Formula 1 car, this model is made of carbon fiber, a material that gives the car safely and torsional rigidity to the high levels of the Coupe. These characteristics, combined with the chassis derived from the world of sports competitions, allowing the car to deliver outstanding performance. The maximum speed of the new high-performance sports, has an AMG V8 compressor engine from 460 kW/626 hp, is equal to 332 km / h, identical to that of the Coupe. The Roadster has a complete open-air driving pleasure and thanks to the fully retractable top, the occupants are entitled to the highest levels of comfort in daily use. Mercedes-Benz SLR Roadster opens up a new dimension in the segment of super scoperte.La new SLR McLaren Roadster is designed to gain a special position among high performance outdoor sports, thanks to its technology derived from the world of motor racing and the use of high-tech materials that, despite the advantages they offer, usually found only on limited parts of prestigious cars, because of high cost and sophisticated manufacturing processes required. In particular, in the case of plastics reinforced with carbon fiber (CFRP) used for the new Roadster, Mercedes-Benz and its Formula 1 partner McLaren to have many years of experience in working with this material, used in aerospace. In the event of any impact, the carbon fiber has a level of energy absorption four times higher than steel and aluminum, while the weight savings resulting from the use of this material hight-tech is about 50 %. The new high-performance roadster has benefited greatly from this know-how. Specifically for this model, the complex technology of carbon fibers has been further and intelligently perfected in accordance with the requirements of the monocoque chassis. The result is low weight, exemplary energy absorption and impact protection of occupants and a high degree of torsional stiffness unattained in the "discovery". These technical features allow you to achieve excellent driving dynamics, as good as the coupe supersportivi.Capote improved fabric for high-speed light The fully retractable top will fit perfectly with exceptional dynamic qualities of the Roadster, in harmony with the sleek lines of the SLR McLaren . The material in which the roof is made of a new concept, and perfect for everyday use in all weather conditions, gives the high-performance sports features exceptional and unusual for a roadster. For example, the maximum speed the car reaches the same high levels of the Coupe, which is 332 km / h. In addition, due to its excellent cabin aeroacoustic, conversation can be over 200 km / h. The soft top opens and closes with a semi-automatic mechanism in less than 10 seconds, while highlighting the desire for comfort and character purist roadster to be. " To open the hood, just unlock it from the windscreen frame and briefly raised, after which it folds away electrically. Also in the front section has an integrated aluminum cover that conceals elegantly the hood when folded. To ensure high safety standards ensure that steel-reinforced A-pillars and two fixed roll-bar. Sophisticated aerodynamics and chassis competizioneLa Roadster has been optimized for high-speed wind tunnel, reaching benchmarks in terms of handling, aeroacoustics and aerodynamics. The new model uses both the aerodynamic concept already developed for the Coupe, with an Airbrake integrated into the lid and a diffusor in the rear bumper to provide increased downforce on the rear axle. To obtain an optimal weight distribution that ensures the highest levels of driving dynamics and high braking stability, Mercedes-Benz SLR McLaren Roadster was designed as a sports car with the engine in the front-center, housed behind the front. Its V8 Kompressor AMG with water intercooler, three-valve technology, dry sump lubrication and four metal catalytic converters, is installed at the bottom to further lower the center of gravity, to the benefit of driving dynamics. With 460 kW/626 hp and maximum torque of 780 Nm, the AMG V8 compressor engine, paired with five-speed automatic transmission with AMG Speedshift R, allowing the roadster to accelerate from 0 to 100 km / h in 3.8 seconds . The two-seater is equipped with suspension setups on the track, an electrohydraulic brake system and disc brakes Carbon-ceramic resistant to the most severe stress, which offer optimal performance, high heat resistance and durability.
