Frankfurt 2015: Brabus Lays Its Hands On The Mercedes-AMG GT S, Now Produces 600HP, 750Nm

“You can never have enough power, especially in a sports car.” That’s Brabus’ philosophy and it continues with their new tuning kit for the Mercedes-AMG GT S, which will make its world premiere at the 2015 Frankfurt Motor Show.

With a simple ECU retune using Brabus’ aptly-named PowerXtra B40 – 600 performance kit, the 4.0-litre bi-turbo V8 engine in the stock GT S gets a new injection and ignition mapping while the boost pressure is moderately increased. As a result, 600hp at 6,400 rpm and a peak torque of 750Nm at 4,800 rpm, is now made available to the driver, representing a 90hp/100Nm increase.

This bumps the performance of the GT S noticeably with the century sprint accomplished in just 3.6 seconds (0.2 seconds faster) and a higher top speed of 325 km/h (15 km/h more). This significant gain in power doesn’t come at the expense of Mother Earth either because the Brabus-tuned version complies with the same strict emissions standards as the production car.

Aside from the ECU tuning, a Brabus quad sports exhaust is also available for both the standard GT and GT S models. Weighing about 40% less than the stock exhaust thanks to a combination of titanium and carbon in its construction, the exhaust also optimises the power delivery of the V8 engine.

Being the humorous people that Brabus are, electronically controlled butterfly valves located on the exhausts are operated from the cockpit. In its “coming home” setting, the noise emitted is even quieter than that of the production exhaust, useful when you’re trying to get the car home late at night.

However, if you want to wake the neighbours up, open up the valves and they’ll be able to experience the full aural force of the eight-cylinder engine, which of course, sounds sportier and more powerful than the stock exhaust.

Complementing the performance enhancements are changes to the exterior and interior as well. Carbon fibre is the primary material used on the exterior visual upgrades with a Brabus front spoiler (with daytime-running lights) that reduces lift at high speeds and feature new side air intakes that route cool air more efficiently.

Along the side are new air outlets that bear ‘Brabus’ badging that light up in blue when the keyless-entry remote or a door handle are operated. Rocker panels located near the rear wheels also optimise airflow while giving the car sleeker visual stance.

Moving on to the rear, a Brabus-made rear spoiler and diffuser is fitted where the latter features cutouts for the four tailpipes. Rounding up the visual enhancements are Brabus Monoblock F “Platinum Edition” cross-spoke wheels with 20-inch ones at the front and larger 21-inchers at the back, available with a mirror-polished, brushed or titanium-coloured finish. New springs accompany these tyres, lowering the ride height by 15mm.

Inside, Brabus have applied unique touches to as part of the tuning kit with carbon scuff plates with stainless-steel inserts and a backlit Brabus logo, whose color changes between red and white, and matte anodized or chrome-plated aluminum pedals. The aluminium paddle shifters are also repositioned to a more ergonomic position on the steering wheel as well.

Further bespoke options are available for the upholstery with different materials and colours available for choice, as well as inlays for the dashboard, center console and door panels.
