Audi has taken the wraps off the new S6 Sedan and Avant, and S7 Sportback, a year after the cooking A6 and A7 were launched. Both petrol and diesel are to be offered, but prices are yet to be announced.

For petrol, the proven 2.9-litre TFSI unit will return, making 335kW and 600Nm, enhanced by an electrically powered compressor (EPC) and a 48V mild hybrid system.

Also a likely starter is the 3.0-litre turbodiesel offering 257kW and 700Nm with the same electric add-on goodies. About the EPC, Audi says it essentially removes turbo lag, responding in less than one-quarter of a second, adding an extra 7kW to the system output and operates at a maximum speed of 70,000rpm.

The mild hybrid system comprises a belt alternator starter (BAS) and 10Ah lithium-ion battery. The BAS is connected to the crankshaft and can regenerate up to 8kW of energy during deceleration. This can be used to keep the S6 and S7 moving without engine power from 22km/h. It can also let the car coast for 40 seconds under the right conditions.

These models can hit 100km/h in five seconds flat in the S6 Sedan while the S6 Avant and S7 Sportback each take 5.1 seconds.

All models feature an eight-speed automatic and drive is sent to all four wheels thanks to permanent all-wheel drive.

Elsewhere is optional all-wheel steering, which turns the rear wheels up to five degrees opposite to the fronts at up to 60km/h or up to two degrees in the same direction as the fronts above 60km/h to enhance directional stability. Adaptive damping is standard, while ride height is dropped by 20mm in the S6 and 10mm for the S7 thanks to S sport suspension. Adaptive air suspension is another option, as is a sport rear differential.

Beefy 20-inch wheels are standard, upgradeable to 21-inches, all fitted with 255/40 rubber, which feature 'torus absorbers' (foam layers bonded into the tyres). The concept is that these "eliminate annoying droning frequencies" to provide "high acoustic comfort despite their size".

Every model gets Audi’s 12.3-inch Virtual Cockpit, four-zone climate control and the new MMI Navigation Plus infotainment system.

The local variants of the new S6/S7 should be detailed quite soon. Expect them late in the year.
