It’s been a while since we’ve heard much from big horsepower mongers Brabus, but it’s now clear that the aftermarket tuner was saving something special for the Geneva Motor Show.

The latest outrageous creation from the German tuner is a new twin-turbocharged version of the Mercedes-Benz SLS AMG supercar that promises a mad output of 700 horsepower (520kW) and 847Nm of torque.

In addition to the frightening powerplant, the modified Merc also looks tougher with Brabus’ Widestar bodykit and a fully customised interior including some trick ambient lighting.

To achieve the massive dose of power, Brabus engineers developed a new twin-turbocharger system for the AMG’s 6.2-litre V-8, which includes high-performance exhaust manifolds, an oversized intercooling system and a dual-flow intake manifold with high-flow air filters. There’s also forged pistons and a remapped ECU with an electronic boost controller.

The end result is staggering performance and combined with the car’s seven-speed automatic transmission, the o-100kph sprint can be achieved in just 3.7 seconds with a top speed 340kph.

Inside, leather and Alcantara is found on most surfaces, as well as a sports steering wheel and matte anodized aluminum pedals and foot rest add further sporty highlights.
