The new Brabus B63S-700 6x6, which was revealed at the Frankfurt motor show, is an even more exclusive and powerful version of Mercedes' niche G63 AMG 6x6.
Standard versions of the G63 AMG 6x6 produce 536bhp and 561bhp, which is channelled to all six wheels via an AMG Speedshift Plus 7G-Tronic automatic transmission. Brabus, however, has boosted that figure to 691bhp and a substantial 97.8kgm thanks to the addition of its 'B63S-700' performance kit. The significant gains, of 155bhp and 20.3kgm, are thanks to the installation of a pair of new turbochargers, a tweaked ECU, high-flow catalytic convertors, a sports exhaust system and the additional heat shielding for the intake system.
Consequently the six-wheeled 3775kg powerhouse is now capable of sprinting from 0-100kph in 7.4sec, although the top speed remains unchanged at 160kph - an electrical limitation enforced to protect the 37-inch off-road tyres, rather than the powertrain.The B63S-700 6x6 also features an exhaust valve system that offers 'Sport' and 'Coming Home' modes, allowing for offering 'optimised' power and exhaust noise - or relative silence - when desired.In order to increase the imposing and purposeful nature of the B63S-700, Brabus has added a front spoiler, a special grille with an integrated Brabus logo, black xenon headlights, a host of carbonfibre parts and special finishes.
The upgrades continue inside, with a combination of finely-stitched leather and Alcantara. Both the floor and roof lining are finished in leather too, in an effort to deliver a truly top-class feel. Further improvements come in the form of stainless-steel scuff plates with illuminated Brabus logos, special alloy shift paddles and other minor aluminium highlights.
