The most powerful Mercedes G-Class (aka G-Wagen) up to now has been the 507bhp G55 AMG, but a new generation of G (with a new interior package and styling updates) includes a pair of new AMG models; this slightly warped 537bhp G63 and the frankly psychopathic G65, a twin-turbo V12 monster with 612bhp, LHD only, limited production and a price tag of 264,000 euros (!) in Germany.

The G63 driven here will be available in both LHD and RHD when it goes on sale in June and is equipped with the twin-turbo 5461cc V8 recently introduced in a range of AMG cars, including the SL63 we drove last week. The G63 also comes with the latest version of the excellent 7G-tronic automatic transmission featuring ECO stop/start function as standard. Fortunately, that’s the only nod towards the eco-warriors you’ll find on the G63, as the rest of the specification is just as bonkers as ever.

Harry Metcalfe introduces us to the new Mercedes-Benz G63 AMG - and its interesting dynamics - in the video below.
