Video: Mercedes G63 AMG

Replacing the old G55 AMG, Mercedes-Benz's new G63 is fitted with the 5.5-litre bi-turbo V8, which pushes out an impressive 536bhp. Not quite enough for you? There's going to be an even more absurd G65 AMG, which uses the monstrous 603bhp V12 bi-turbo engine, as seen in the recently unveiled SL65 AMG.

Differences between the Standard G-Class and the AMG models include a larger, more aggressive front bumper, larger 20-inch alloy wheels and AMG grille.
