Do big power and big weight trump... less power and less weight? There's only one way to really find out.

Much has been made of the fact Mercedes-Benz slots a twin-turbo AMG V8 into its G-Class. Sure, the G63 looks like an old-fashioned off-roader, but it's fast enough to make sports cars nervous in a straight line.

It might weigh 2500kg, but 430kW and 850Nm are serious outputs. In its latest head-to-head (to-head), the team at Top Gear UK lined it up against the five-cylinder Audi RS3 and four-cylinder Porsche 718 Cayman GTS.

The former puts 294kW and 480Nm to the road through all four wheels, the latter 269kW and 430Nm to the rears exclusively.

But the RS3 (1520kg) and 718 (1480kg) are both significantly lighter than the G63, though. You can probably see where this is going. Check out the race below, and let us know what you think in the comments.
