The cabin is beautifully crafted using the best materials while the dashboard layout is typically Audi - form as well as function. There’s no faulting the build quality either, as the RS5 boasts a cabin that has clearly been built to last.

Steering wheel controls help you keep your eyes on the road while navigating the on-board menus and the simple MMI control system on the centre console is quick to learn and use on the move.

This is not a car set up to be comfortable, so it’s no surprise that Audi RS5 comfort levels aren’t one of its stronger points.

The low-speed ride in dynamic mode is pretty unbearable but it starts to settle down more as speeds increase. Comfort mode is the best compromise, but regardless of setting – in the cabriolet you can see parts of the interior shaking as the firm set-up fails to deal with the imperfections below. Those 19inch wheels don’t help matters, and the thump of the thinly-wrapped rim as it hits potholes can be worrying.

Thankfully, the well-bolstered seats do half the job of absorbing the bumps but during our test on lumpy rural UK roads we spent a lot of time being jostled about.

Audi has done well to iron out road and wind noise without insulating so much that you can't hear what is a truly fantastic-sounding engine. The engineers have included an 'overun' exhaust sound when the auto is changing down and it never fails to bring a smile to your face – made even better by the ability to lower the roof in the cabriolet.

However the space in the rear is limited – both for headroom and legroom.
