Renault, make it so...

The Renault Alpine A110-50 concept makes a hellish racket. This is a rare compliment to pay a concept car, for most concept cars do not make any noise at all. Most concept cars sit inert on their motor-show stands, hiding their fictional engines and vapourware performance under polished bodywork that would fall to pieces at the first sign of a corner. The A110-50 isn't most concept cars.

The A110-50 announced itself to the world on the Friday of the Monaco Grand Prix weekend, lighting up its rear wheels as it exited the start line in a big dollop of drift before tearing around the F1 track at pace in the hands of Renault CEO Carlos Tavares, bellowing a rasping, race-car scream as it charged through the tunnel at triple-figure speeds. TopGear was there. Our ears are still smarting.
