And the car's performance is searing. The 0-60mph sprint takes around five seconds, while top speed is limited to 155mph. In-gear flexibility is the S5's most impressive feature, though, with lots of punch all the way to the 7,000rpm red line, accompanied by a deep-chested V8 rumble. Motorway cruising is brilliantly relaxed, too.

However, the six-speed gearbox is notchy which, combined with a sharp throttle and clutch, can make progress jerky at low speed. The stiff suspension is also very unforgiving, and the S5 is uncomfortable around town.

On smooth tarmac it's much better. Body roll is well controlled and the drivetrain offers total traction at all times. The steering is quick and accurate, too, but lacks feedback. So while the S5 feels very fast and competent, it's ultimately a bit numb.

In our opinion, BMW's 335Ci is still the better all-rounder, particularly when you consider the price. At £39,825, the S5 is £6,030 more than its rival - and that's a lot extra to pay.
