Audi RS 6 Avant: Drivetrain

Source: Audi AG

The engine’s exceptional power output of 426 kW (580 bhp) necessitates an appropriately superior drivetrain. The new Audi RS 6 Avant comes standard with the latest generation of the tiptronic automatic transmission, designed with six forward gears for sporty performance. It transfers the engine’s torque to the quattro permanent all-wheel drive, which itself is also built for the ultimate in driving dynamics.

The tiptronic six-speed automatic transmission represents the vanguard of a new generation of drivetrains that are now entering service throughout the Audi portfolio. It is extremely compact and light, and harmonizes perfectly with the dynamic character of the RS 6 Avant. Its torque converter, which operates in the activated lock-up mode most of the time, its hydraulics and its electronic management system, which adapts to individual driving styles, have been optimized for direct coupling to the engine. Response time has been shortened to a tenth of a second and shifting time has been cut in half – with kickdown responding in less than a second.

A deliberately short set of transmission ratios was chosen; even in sixth gear, the most powerful production Audi of all time offers impressive acceleration.

The driver can select the sport mode “S” with the selector lever; the shift point maps are then altered for higher engine speeds. Shifting can also be performed manually with either the lever or the shift paddles. The aluminum-look paddles are located behind the steering wheel rim and turn with it.

Driving pleasure and stability – the quattro driveline

As is typical for an Audi, the new Audi RS 6 Avant also relies on quattro permanent all-wheel drive with the superior traction and exhilarating driving pleasure it offers under all conditions. The quattro driveline is yet another winning motor sport technology from Audi. Its current generation, featuring asymmetrical, dynamic torque distribution, is further testimony to the philosophy of “Vorsprung durch Technik.”

A Torsen center differential installed longitudinally in the driveline distributes the torque between the front and rear axles. The normal split is 40 percent to the front axle and 60 percent to the rear – this slight rear bias was chosen to underscore the sporty nature of the new Audi RS 6 Avant. If the road surface conditions change, the purely mechanical differential responds instantaneously – it can divert up to 85 percent of the torque to the rear wheels or as much as 65 percent to the front wheels. Should a wheel on one axle spin, it is braked by the EDL electronic differential lock.

For the driver, this technology package adds up to outstanding agility, extremely stable handling and uncompromising traction when coming out of a bend – even on wet road surfaces where competitors helplessly struggle for traction with only two driven wheels. The handling dynamics of the RS 6 Avant are further enhanced by its relatively low engine weight, which results in a balanced distribution of axle loads. The battery and the energy management system are located in the luggage compartment for this same reason.
