2002 Audi RS6 & RS6 Avant
Bi-Turbo V8
The Audi RS6 has a unique high–tech package at launch. Its immense power characteristic,
Audi's Quattro permanent four-wheel drive, high-tech brake system and innovative DRC suspension set new standards in the segment of high-performance vehicles.
Development work on the V8 Bi-Turbo 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.
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.
To maintain the emphasis on an overtly sporty driving style, the tiptronic five–speed automatic transmission for the RS 6 incorporates a dynamic Sport program: the S drive position on the one hand pushes each individual gear up to higher speed at full throttle, and on the other hand permits swifter downshifts. Depending on the level of lateral acceleration, the transmission management can adjust the shift points upwards. This avoids undesirable gearshifts on a bend. The RS 6 driver can of course also operate the transmission manually: either by briefly pressing the selector lever or by pressing a shift paddle on the steering wheel, like in motor racing. When the driver operates the shift paddle, his choice of gear overrides the driving program currently in use.
