The Frankfurt Motor Show just left another gift under the tree. The Brabus B63S 6×6 ($TBA) is the designers take on the Mercedes-Benz G63 6×6. Brabus has taken the already capable off-roader and made it a beast. They’ve updated the twin-turbo 5.5 liter V8 so that it now gets 700 horses. This huge machine can now get to 60 mph in under 7.4 seconds. Additional specs include exterior carbon fiber accents, LED daytime running lights, premium leather upholstery for the interior, Alcantara trim, bespoke headliner, and alloy pedals. Expect the B63S to cost over $500,000 when the price is finally released. Check out more pictures after the break.
