Brabus B63 - 620 Widestar launched

The latest conversion from Brabus is based on the Mercedes-Benz GL 63 AMG seven-seat SUV. Called the B63 - 620 Widestar, that name gives a couple of clues about the changes that have been applied.

Firstly, the ‘620’ denotes that the 5,461 cc bi-turbo V8 engine’s power output is up from the usual 550 bhp (410 kW / 557 PS) to 611 bhp (456 kW / 620 PS). The 11% increase comes courtesy of a sports exhaust system, together with a PowerXtra ‘plug-and-play’ module that revises the injection and ignition mapping and gives a slightly higher boost pressure.

As a result, acceleration from rest to 62 mph (100 km/h) takes 4.7 seconds, which actually doesn’t seem much quicker than the regular model’s time of 4.9 seconds. Altering the electronic limiter has raised the top speed from 155 mph (250 km/h) to 174 mph (280 km/h), though.

The ‘Widestar’ designation meanwhile signifies that the B63 features extended wheel arches that add 8 cm (3.1”) to the vehicle’s width. They’re complemented by a redesigned front apron that reduces front-end aerodynamic lift and provides better cooling via its larger air intakes. At the rear are a bespoke bumper and a roof-mounted spoiler.

Completing the package is a range of alloy wheels that are available in 21”, 22” or 23” diameters. Buyers can also go for an upgraded braking set-up and a selection of interior customisation options.
