Presented with a 441kW Audi RS 7 and the task of improving it, “make it faster” presumably wouldn’t be high on too many people’s priority lists. Nevertheless, here we have the faster, more powerful and grippier Audi RS 7 Performance. Essentially a mid-life facelift for the model, the result is a staggeringly capable sedan-hatch-coupe-thing, though this improved athleticism doesn’t come without a cost, and we’re not talking financial.
