Ingolstadt, Germany - Audi’s manic wagon is back for another generation and it’s packing more muscle than ever, thanks to a revised 4-litre twin-turbo V8 that now has mild hybrid capability.
Let’s get straight to the numbers. The RS6 Avant’s new powertrain matches the 441kW power output of the ‘standard’ BMW M5, while 800Nm is available between 2050 and 4500rpm. That’s enough to get the new RS6 from 0-100km/h in 3.6 seconds, says Audi, with 200km/h coming up in just 12 seconds. The top speed, as always, is electronically limited to 250km/h.
The soundtrack is regulated by a flap system linked to the Audi Drive Select, which allows drivers to customise engine acoustics through new ‘RS1’ and ‘RS2’ modes.
Like many of its modern Audi counterparts, the RS6 Avant has a 48-volt main electrical system and features a mild hybrid set-up with a belt alternator. The system can recover up to 12kW of power during light deceleration, which is then stored in a separate lithium ion battery. Ultimately, the set-up is said to save up to 0.8 litres per 100km in everyday driving. Cylinder deactivation also reduces consumption, although there are only so many ways you can mitigate the thirst of a twin-turbo V8.
The engine is paired with an eight-speed tiptronic autobox and a quattro all-wheel-drive system that distributes 60 percent of the torque to the back wheels under normal circumstances, although up to 85 percent can be pushed back there in sportier driving circumstances. A sport differential on the back axle sharpens things further by regulating the torque distribution between the rear wheels as needed.
