Will it be the Audi RS3 saloon, all 395bhp and with all-wheel drive to propel it?
Or will it be the BMW M2? On the face of it, it has lesser advantages, being only two-wheel drive and having just 370bhp. But it is lighter.
And to compensate for the Audi's natural traction advantage, we'll try it both with launch control, and from a standing start.
Which, then, will be faster?
