Our market analysts think the RS4 will retain some of the strongest residual values in the Audi range – stronger even than the BMW M3 coupé – which means it is likely to still be worth nearly £30,000 in four years’ time. Fitted with the carbon-ceramic front brakes of our test car, it also resisted wearing through its consumables admirably during its time with us. It spent days on a circuit for this road test and our upcoming Best Driver’s Car feature, during which it steadfastly refused to burn through its tyres and brakes.
It did, however, burn through quite a lot of petrol, as 32.4mpg even on our relatively gentle touring route would suggest. That might limit its appeal in the eyes of some buyers but, if you can live with the fuel consumption, it remains one of the most intoxicating drivetrains around.
