Overview
The RS 6's 4991 cc V10 engine produced 426.5 kW at 6,250 to 6,700 rpm and 650 Nm of torque from 1,500 to 6,250 rpm, 52 kW and 150 Nm more than BMW's 5.0L V10. , the RS6 was Audi's single most powerful car ever, and positioned the car ahead of its closest competitors, the BMW M5 and the Mercedes-Benz E63 AMG in terms of engine output, both of which have naturally aspirated engines.
C6 bodywork and styling
Visually, the RS 6 differed from the related S6, having flared front and rear wheel arches (fenders), harking back to the original Audi Quattro, to allow for a wider wheel track. It also had no front fog lights to allow for larger frontal air intakes (for the two side-mounted intercoolers (SMICs), and additional radiators).
C6 powertrain
The engine (parts code: 07L, identification code: BUH) of the RS6 was what Audi claimed to be the first all-aluminium alloy even firing 5.0-litre (4991 cc) 90° V10 twin-turbocharged ("biturbo"), Fuel Stratified Injection (FSI), with a dry sump lubrication system. This engine is related to the naturally aspirated V10 found in the Audi R8, S6 and S8, but the RS 6's engine has around 400 unique parts.
C6 steering and suspension
Like the previous RS6 and the B7 RS 4, this generation of RS 6 includes Audi's "Dynamic Ride Control" (DRC) Sports suspension system. The system is mainly mechanical, using a pump to provide additional pressure in the diagonally linked dampers (shock absorber) during cornering, to counteract rolling and pitching. The system can dynamically adjust the stiffness at each damper constantly to maintain both a comfortable ride and a high grip. In this version, it has a three-way level control, selectable from the Multi Media Interface controls.
