In the past, Audi has had a way of negating any subjective concern with its RS models’ dynamic limitations by machine-gunning them with big (or impossibly small) numbers.
For the Audi RS6, unsurprisingly, it’s that minuscule 0-62mph time – and the unique market position of its quattro drivetrain – which will be used to coax buyers away from the rear-driven BMW M5, Jaguar XFR-S and Mercedes E63 AMG Estate.
While the latter is capable of flattening Audi’s luggage capacity boast (providing 130 litres more space with seats up, and a full 270 litres more with them down), none can lay claim to a sub 4-second sprint, and none offer the flexibility or reassuring stability of all-wheel drive.
We averaged economy of 19.6mpg over the whole test, a figure marginally bettered by the XFR we tested, but an improvement over the catastrophic 16.8mpg of the V10 model.
As a range-topper, the standard kit list is typically decent, although this being an Audi there is a healthy option list to inflate the final price – hence the £91,450 sticker that would normally have appeared on our test car’s windscreen.
