Times are rapidly changing at Audi, and not necessarily in the direction you would think. See, once upon a time the S6 and S7 had V8 engines. Hell, the S6 even had a N/A V10 for a while. You heard that right. In these more environmentally-aware times, you’d expect Audi to downsize. But no no no say audi.
A turbocharged petrol V6 seems like the obvious contender, and indeed that’s what the new S6 and 7 will come with in the USA, Asia and the Middle East. It’s the same 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 516lb ft. Less powerful, but torquier than the cars they replace. The S6 saloon does 0-62mph in 5 seconds, while both the S6 Avant and S7 take a tenth of a second longer. All three of them are limited to 155mph (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 percent of drive can be sent rearwards, should the need present itself. 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 simply 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 will begin arriving in summer. No word on price, but expect upwards of £60k for the S6, and £70k for the S7. Get the estate.
