The eight-cylinder V-engine with a displacement of 4.2 litres has been specially developed for the Audi RS 6. It achieves a permanent maximum power output of 331 kW (450 bhp) between 5700 and 6400 rpm. Its peak torque of 560 Newton-metres is available across an extremely wide range of engine speeds, from 1950 to 5600 rpm.
Development work on the V8 biturbo engine, which has five valves per cylinder unit, intake camshafts with hydraulic adjustment and two-stage intake manifolds, was spearheaded by quattro GmbH in close collaboration with AUDI AG's engine development department at Neckarsulm.
Most of the impressive power gain is attributable to the two turbochargers, the efficiency of which is further enhanced by two pressure-loss optimised intercoolers. There is one turbocharger per bank of cylinders. The admission and exhaust ports have been modified in line with the engine's higher performance, and the cross-section of the air ducts enlarged at both the intake and thrust side.
The adapted engine management is another key aspect of the RS 6 engine's efficiency. The Motronic ME 7.1.1 operates with boost pressure, knock and exhaust-gas temperature control. quattro GmbH has developed a dual-branch exhaust system with backpressure-optimised middle and rear silencers, larger-section pipes, and primary and main catalytic converters with a metal base. The RS 6 thus satisfies the EU3 emission standard.
To distribute the weight more effectively throughout the vehicle, the battery has been moved further back, into the spare wheel's recess. The upper section of the air cleaner is made from a carbon fibre composite material; together with a further carbon fibre cover over the front section of the engine compartment, it gives the engine a striking appearance.
In keeping with the car's high performance, quattro GmbH has developed a completely new brake system for the RS 6. Large brake discs of a composite design have been fitted on both the front and rear wheels. This technology, which originated in the world of motor sport, involves fixing a cast friction ring to an aluminium brake-disc chamber by means of 14 pins. This "floating" arrangement improves the stability of the brake discs, particularly when exposed to extreme loads and at high operating temperatures.
The ventilated, perforated disc brakes have a diameter of 365 millimetres at the front, and 335 millimetres at the rear. The grip is achieved by means of eight-piston brake callipers at the front and single-piston floating callipers at the rear. The parameters of the ABS system and the electronic brake-force distribution system have been specifically redefined for the high-performance brake system. [HR][/HR]
