The new Audi RS 6 Driving Video
The 4.0 TFSI in the new Audi RS6 Avant delivers 600PS and 800 Nm (590.0 lb-ft) of torque, which is maintained at this high level between 2,050 and 4,500 rpm.
In just 3.6 seconds the high-performance Avant sprints from zero to 62mph, and where conditions permit the driver can see 124mph by the time 12 seconds have elapsed.
Top speed is electronically governed at 155mph.
Thanks to the 48-volt main electrical system the twin-turbo V8 combines maximum performance with high efficiency.
A belt alternator starter lies at the heart of the mild hybrid system (MHEV).
Up to 12 kW of power can be recovered during light deceleration and stored in a separate lithium-ion battery.
If the driver lifts off the accelerator at a speed of between 34 and 99mph, the drive management selects one of two options: Depending on the driving situation and setting in the standard Audi drive select dynamic driving system the new Audi RS6 Avant recovers energy or coasts for up to 40 seconds with the engine switched off.
Re-applying pressure on the accelerator instructs the belt alternator starter to restart the engine.
MHEV technology allows for start/stop operation at speeds of up to 13mph.
Fuel savings of up to 0.8 litres per 100 kilometres are possible in everyday driving.
