The Brabus B63S-700 has just been unveiled at the Frankfurt Motor Show, boasting a 5.5-litre V8 Biturbo now developing 690bhp and 980Nm of torque. That’s a 154bhp power upgrade over the Mercedes G63 AMG on which it’s based, with power still being sent to all six wheels.
The performance upgrade has been made achievable by the turbochargers having been replaced for two special Brabus turbochargers with a larger compressor unit, producing a higher boost pressure. A tweaked ECU, new stainless-steel sports exhaust and cooling upgrades also help boost power.
The engine is mated to an AMG speedshift plus 7G-Tronic automatic transmission, meaning 62mph is cracked in 7.4 seconds. Impressive stuff considering the Brabus B63S-700 weighs just shy of four tons at 3775kg. Top speed is limited to 100mph, however, an enforcement of the 37-inch wheels rather than the powertrain.
The upgrades under the bonnet have also been matched with some visual drama, too. Brabus has fitted imposing front and rear bumpers along with modified side skirts and a carbon fibre bonnet scoop. Dark tinted LED lights and daytime running lights have also been integrated into the front bumper.
Inside, the interior is festooned with extended red leather along with black and red Alcantara trim. Stainless-steel scuff plates and decorative stitching in the floor, door panels and headliner complete the interior transformation.
Pricing for the B63S-700 has not been announced by Brabus but with the standard model estimated to cost in excess of £350,000, Brabus will no doubt be charging a significant premium for “the mightiest G model ever.”
