This is unquestionably a quick car, thanks in part to its V6 delivering its maximum 369lb ft torque output from as low as 1370rpm upwards. Allied with Quattro traction, the S5 rockets out of junctions – which is useful, given how infrequently you’ll be let out of them. The new engine isn’t the most characterful, but its six-cylinder tally does result in it sounding much more interesting than the four-cylinder Mercedes-AMG CLA 45, albeit less overtly raspy than the six-cylinder C43 - although you might prefer the S5's more subtle soundtrack.
