Times have changed at Audi, and not necessarily in the way you’d think. See, once upon a time the S6 and S7 had V8 engines. Hell, the S6 even had a N/A V10 for a bit. In these more environmentally-aware times, you’d expect Audi to downsize.
A turbocharged petrol V6 seems like the obvious choice, and indeed that’s what the new S6 and 7 will come with in the USA, Asia and the Middle East. It’s the 2.9-litre V6 you get in the S4 and S5.
But in Europe? Diesel. Specifically, the 3.0-litre turbocharged V6 diesel from the SQ5, complete with an electric compressor for instant torque and a 48-volt mild-hybrid system, giving engine-off coasting and super-smooth stop/start.
You’re looking at 344bhp and 700Nm. Less powerful, but torquier than the cars they replace. The S6 saloon does 0-100kph in 5 seconds, while both the S6 Avant and S7 take a tenth of a second longer. All three of them are limited to 250kph, because Germany, and should deliver over 40mpg.
The gearbox is a conventional eight-speed auto, driving all four wheels with a 40/60 front/rear power split. However up to 85 per cent of drive can be sent rearwards, should conditions necessitate. A ‘Sport Differential’ for vectoring torque across the rear axle is optional, as is four-wheel steering (from the SQ7), a hefty set of ceramic brakes and adaptive air suspension.
As for looks - the differences between the S6/7 and regular ones are slight. And that’s just how we like it. The biggest giveaway you’re not just driving a 2.0-litre TDI is the set of quad exhausts. No doubt there will be some noise augmentation going on to make them seem worthwhile.
European cars arrive in the summer. No word on price, but expect upwards of £60k for the S6, and £70k for the S7. Get the estate.
