400hp and 480nm: numbers which 15 years ago would've been impressive for a supercar. In 2018, they're the figures for a five door hatchback. The Audi RS 3 isn't just any old hatchback though - a 2.5-litre five cylinder turbo is matched to a Quattro all-wheel drive system for speed across a twisty road that even the latest supercars would struggle to match.

The Mercedes-AMG A45 has similarly bonkers numbers and is the current hyper hatch king. So can the latest RS 3 compete? I compare the two to find out.

A big thank you to Inchcape Mercedes-Benz for lending us the Mercedes-AMG A45 –
