For most people the Mercedes-AMG GT 63 S represents plenty enough power and torque for Autobahn roleplaying or track day debauchery. But, for the rare few who want even more from their three-pointed star sports car killer, Brabus have got you covered.

The tuning firm has unveiled its new Rocket 900 — a go harder version of the GT 63 S, fitted with some monstrous powertrain upgrades, a comprehensive new aero kit, and a reworked cabin.

Starting at the business end, the Rocket produces 662kW of power and 1250Nm of torque. That’s a whopping 192kW/150Nm lift over the standard model. Brabus claims the big behemoth can scamper to 100km/h in 2.8 seconds, 200km/h in 9.7 seconds, and 300km/h in 23.9 seconds. Top speed is limited to 330km/h.

The illustrious tuner has made a raft of changes under the bonnet to make these numbers possible. These include boring out the block, increasing displacement from 4.0-litres to 4.5-litres. The Rocket gains a pair of new turbochargers and a larger compressor unit to increase potential boost pressure, and a new stainless steel quad-exhaust system gives it big bark. Naturally, all of this has been supported by a new cooling set-up, inclusive of a carbon ram-air intake on either side of the primary grille.

These intakes make for a fairly aggro looking front end; each punching a hole through the GT 63’s Panamerica grille. Wider fender flares for a wider track, a hefty rear spoiler, various red highlights, and new 21 or 22-inch wheels somewhat reminiscent of the Mercedes ‘Monoblock’ wheel style are among the exterior tweaks.

Inside, owners get quilted leather buckets with grey stitching, red detailing on the gear selector, new floor mats, and Brabus branding all over the shop — from the seats to the steering wheel to the pedals. Even the engine bay gets a bit of a visual spruce up, via a new red-carbon airbox cover with its own build plate.

The focus on comfort inside underlines Brabus’ hopes to make the Rocket 900 a comfortable cruiser. Those large wheels are set to be negated in the ride-quality stakes by a new air suspension system, with comfort and sport settings designed to make the model versatile.

How much is it? Well, if you have to ask there’s a very real possibility that you can’t afford it. The first edition model depicted here is priced at €435,800 — that’s $770,740, or more than double the GT 63 S’s local sticker price of $332,000.
