The heart of Brabus' power upgrade is its custom control module to tweak the engine management, and the result is adjusted boost pressure and the mapping for the fuel injection and ignition. There's also a stainless steel exhaust with butterflies that vary between "Sport" and an appropriately named "Coming Home" mode at the press of a button. The chrome tailpipes add an extra visual pop, too.
The G500 4x4² rides on off-road tires, and even after Brabus' big boost, it's not lightning quick. The run to 62 miles per hour now takes 6.9 seconds, and the rubber also mandates a top speed limited to 130 mph.
For buyers really looking to show off, Brabus has a wild body kit for the G500, too. It includes new lower bumpers and polished underbody guards. Meanwhile, the hood grows a scoop, and the headlight update adds black-tinted Xenon lights with LED turn signals to replace the units usually on the fenders. Inside, a mix of quilted leather, Alcantara and bright red stitches finishes off the brash tweaks.
BRABUS refines the Mercedes G 500 4x4²
368 kW / 500 HP, 710 Nm of torque and exclusive BRABUS luxury appointments for the extreme off-roader
Mercedes G 500 4x4²: the new special model of the G-Class is designed for maximum off-road capabilities and offers the perfect basis for exclusive refinement à la BRABUS (Brabus-Allee, D-46240 Bottrop, phone +49 / (0) 2041 / 777-0, fax +49 / (0) 2041 / 777 111, Internet www.brabus.com).
This includes an increase in the power output of the twin-turbo V8 to 368 kW / 500 HP (493 bhp) and a boost in its peak torque to 710 Nm (523 lb-ft). As a result, the tuned off-roader sprints from rest to 100 km/h (62 mph) in just 6.9 seconds. Due to the all-out off-road tires, the top speed is limited electronically to 210 km/h (130 mph).
The spectacular appearance of the all-wheel-drive car is bolstered further by a high-end BRABUS paint finish and targeted BRABUS bodywork modifications.
An exclusive BRABUS fine leather interior created from Mastik leather and Alcantara refines the interior.
The four-liter eight-cylinder twin-turbo engine of the Mercedes G 500 4x4² produces an ex-factory output of 310 kW / 422 HP (415 bhp) and is consequently an excellent starting point for the new BRABUS B40 - 500 PowerXtra performance kit. The centerpiece of the conversion is a plug-and-play control module that is adapted to the electronic engine management system. BRABUS utilized complex test cycles on state-of-the-art dynamometers as well as in terrain and on the road to recalibrate the electronic boost pressure control and reprogram the mapping for injection and ignition.
The result of these modifications fully lives up to the spectacular appearance of the cross-country vehicle: An extra 58 kW / 78 HP (78 bhp) and an increase in torque by 100 Nm (74 lb-ft) make the SUV weighing more than three tons significantly more agile.
The rated power output of 368 kW / 500 HP (493 bhp) at 5,600 rpm and the high peak torque of 710 Nm (523 lb-ft), available on a plateau between 2,250 and 4,250 rpm, harmonize perfectly with the automatic transmission. Its seven speeds can also be changed manually with ergonomic BRABUS aluminum paddle shifters on the steering wheel.
Equipped with BRABUS B40 - 500 PowerXtra engine tuning, the 4x4² sprints from rest to 100 km/h (62 mph) in just 6.9 seconds. The top speed of the SUV is limited electronically to 210 km/h (130 mph) to protect the all-terrain tires.
Of course, like all its other components, BRABUS backs this performance kit with the in this industry unrivalled BRABUS Tuning Warranty of three years, up to 100,000 kilometers/62,000 miles (see BRABUS Warranty Terms and Conditions, updated July 2013). BRABUS exclusively uses high-tech lubricants from technology partner MOTUL.
Sound, performance and longevity are the outstanding features of the BRABUS stainless-steel sports exhaust system with actively controlled butterfly valves. A button on the steering wheel lets drivers choose between a subtle "coming home" mode and a markedly powerful exhaust note in the "sport" position. The BRABUS exhaust features dual chrome tailpipes on each side of the vehicle and thereby adds some stunning visual highlights in a thrilling side pipe design.
Of course, BRABUS also lends the highest-riding G-Class model ever an even more fascinating appearance by giving the front an equally sophisticated and striking update. BRABUS front bumper panels on the left and right as well as a mirror-polished underride guard upgrade the production bumper. An additional panel under the special radiator grille with integrated BRABUS logo furthermore characterizes the face. The BRABUS hood scoop, the new radiator grille and headlamp surrounds are all made from clear-coated carbon and thereby add further distinctive highlights.
The special BRABUS lighting concept for the G-Class is another visual and functional highlight. It includes LED lights with chrome surrounds integrated into the BRABUS front bumper panels. The black-tinted BRABUS xenon headlamps and daytime running lights with integrated turn signal function are even more dominating features. Precise-fit covers made from clear-coated carbon replace the now redundant production turn signals on top of the fenders. In concert with the carbon structure of the hood scoop and the carbon covers for the exterior mirrors, they effectively round of the menacing front of the SUV.
In addition, BRABUS upgrades the sides with underfloor lighting for the running boards, which is activated by pulling on a door handle or by operating the keyless-entry remote.
Like its counterpart at the front, the rear underride guard is also mirror-polished. The BRABUS rear bumper completes the thrilling rear appearance of the mighty off-roader.
Another focal point of the BRABUS refinement for the Mercedes G 500 4x4² is the interior. The company upholstery shop created an exclusive BRABUS fine leather with arrow-shaped quilting from especially soft and breathable black Mastik leather for IAA 2015 show car. Red seams add an interesting contrast. An Alcantara headliner plus other Alcantara components in the interior as well as carbon inlays adds even more highlights that are striking.
Stainless-steel scuff plates with backlit BRABUS logo welcome the passengers. To make getting in and out easier, BRABUS also offers optional special power-retractable BRABUS steps. The BRABUS interior designers add keen highlights with high-class aluminum components such as pedals and door pins.
