Mercedes tuner Brabus has revealed its latest high-performance SUV. The Brabus B63-620 Widestar is based on the Mercedes-Benz GL63 AMG, but sees power boosted further, and bodywork extended 80mm to create a wider stance.
The GL63 AMG’s 5.5-litre biturbo V8 has been boosted from 550bhp to 611bhp using Brabus’s PowerXtra plug-and-play remapping software. The revised injection and ignition mapping allows the car to accelerate to 62mph in 4.7sec — 0.2sec less than standard — and on to a top speed of 174mph.
The exhaust system features butterfly valves to increase engine volume on the move. A 'Coming Home' mode dampens the sound.
Wheelarch extensions — part of a bodykit that includes new bumpers and a roof spoiler — allow the Brabus GL to be fitted with 23in forged alloy wheels and 305/30 tyres.
Brabus says the body modifications reduce lift on the front axle when travelling, aiding cornering at speed and provide extra brake cooling.
Interior revisions include leather and Alcantara hand-stitched seats.
No prices have been revealed, but expect a significant hike over the standard GL63 AMG’s £91,715 price tag.
