Quattro GmbH presents the RS models as high-performance automobiles under the label of Audi Sport. quattro all-wheel drive is also standard in these cars. The lineup comprises the RS 3 Sportback, the RS Q3 and the RS 6 Avant and RS 7 Sportback models.
The Audi RS 6 Avant, a high-performance sports car for everyday and recreational activities, stands for groundbreaking performance. Its 4.0 TFSI produces 412 kW (560 hp) and 700 Nm (516.3 lb-ft) of torque. It accelerates from 0 to 100 km/h (62.1 mph) in 3.9 seconds. On request the top speed can be extended up to 305 km/h (189.5 mph). In the combined cycle, however, the V8 biturbo consumes just 9.6 liters of fuel per 100 kilometers (24.5 US mpg), corresponding to 223 grams CO2 per kilometer (358.9 g/mi). A key factor in this efficiency is the cylinder-on-demand (COD) system, which can temporarily shut down four cylinders during partial load operation. Active engine bearings compensate for the vibrations that occur in these phases, to ensure continued smooth engine operation.
The power of the eight-cylinder engine is transferred via a sport-tuned, eight-speed tiptronic to the quattro permanent all-wheel drive system, which utilizes a self-locking center differential and distributes the torque asymmetrically and dynamically. Audi can also deliver an optional rear sport differential.
Standard equipment of the high-performance Avant, which rides on 20‑inch wheels, includes RS adaptive air suspension. The dynamically tuned air suspension with controlled damping lowers the body by 20 millimeters (0.8 in) and can be adjusted by the Audi drive select system. Audi offers the more tautly tuned RS sport suspension plus with Dynamic Ride Control (DRC) as an alternative. Other options include dynamic steering and carbon fiber-ceramic disks.
With increased performance and outstanding efficiency, the new RS 6 Avant performance is top of the model line. Its 4.0 TFSI engine with 445 kW (605 hp) and – thanks to the overboost feature – up to 750 Nm (553.2 lb-ft) of torque push acceleration nearly to levels usually reserved for supercars. In just 3.7 seconds, it sprints from 0 to 100 km/h – an improvement of 0.2 seconds compared with the RS 6 basic model. While Audi limits the top speed to 250 km/h (155.3 mph) by default, dynamic package plus makes up to 305 km/h (189.5 mph) possible. Fuel consumption remains unchanged at 9.6 per 100 kilometers (24.5 US mpg), corresponding to 223 CO2 per kilometer (358.9 g/mi). A best value in the segment.
Diverse design details reinforce the preeminent position of the new high-performance model. They include the air inlet duct with quattro logo as well as distinctive add-on parts with a titanium matt look.
