Ingolstadt, 22. February 2010 – Actually the new RS4 turned off when it comes to his fans. At the Geneva Car Salon of 4. Until 14. Marz 2010, however, first shows the RS5. There he presented in his pronounced shell new all-wheel technology and a motor that remains economical in spite of his performance.
Under the hood comes a high-rotating V8 suction motor with 4163 cubic centimeter displacement and benzindirect injection – a turbo ware maybe time rubber, but such a thick sucker still has a special charm. The aggregate is closely related to the ten-cylinder that drives the R8. With 450 hp, the RS5 engine even makes 30 hp more than the smallest R8 machine with 4.2 liters of displacement. Speeds are available: The maximum power is achieved at 8250 revolutions, 430 Nm torque are available between 4000 and 6000 tours, because it is joyful in turning. In just 4.6 seconds, the approximately 1.7 tonnes of heavy coupe should accelerate from zero to 100 km / h. The otherwise electronically limited tip of 250 km / h is read on request only at 280 km / h. In conjunction with the continuous seven-speed dual-clutch transmission S Tronic, the RS5 consumes 10.8 liters of fuel in the EU measurement cycle.
New four-wheel technology
As with Audi ubam, the RS5 also brings its power via all-wheel drive to the strain. When center differential that distributes the forces between front and rear axles, there is a new feature: the so-called crown-gear differential. It may vary widely due to its disk packs the distribution of torque between the axles. If necessary, it passes up to 70 percent to the front or a maximum of 85 percent to the rear. The standard interpretation of 40:60 rear-biased. The new differential works with an electronic torque vectoring, which accesses all four wheels. If one of the inside of the curve Rader is relieved too much at brisk pace, it slows the system down slightly before slippage occurs. This ensures on the one hand for more traction, and on the other hand produces a yaw moment that supports the turning.
