RS6

The RS6 Avant Performance is powered by the same 4.0-litre TFSI twin-turbo V8 engine as the standard RS6, ^[27] but with the help of a revised ECU map, power output was increased to 605 PS (445 kW; 597 bhp) at 6100-6800 rpm, and torque to 750 N⋅m (553 lbf⋅ft) at 2500-5500 rpm.^[28]

Top speed remains limited to 250 km/h (155.3 mph), or 305 km/h (189.5 mph) with Dynamic Plus package, with the 0 to 100 km/h (62.1 mph) time reduced to just 3.7 seconds, and 0 to 200 km/h (124.3 mph) in 12.1 seconds. Despite the improved performance, the fuel economy and CO₂ are unchanged from the standard RS6 Avant.

Performance models were also fitted with Audi’s sports exhaust, choice of optics packs, and privacy glass. They had an updated front bumper design, and were offered with revised wheel choices (up to 21″ diameter). Internally, the cars came with carbon inlays with a blue weave, and half leather-half alcantara seats with blue stitching.
