The 4.0-liter V8 TFSI engine familiar from the RS 6 has been modified for use in the Audi RS 6 performance. The RS high-performance model sprints in just 3.7 seconds from 0 to 100 km/h - an improvement of 0.2 seconds on the basic RS model. As a special highlight, the engine provides an overboost function, in which up to 750 Nm is available to the driver for a short time. After another 8.4 seconds the RS 6 performance breaks through the 200 km/h barrier. With the optional dynamic packages top speed can be boosted from 250 to 280 or 305 km/h.
