Brabus, as you may know, has an incredibly powerful V12 engine – which this year makes 800 horsepower – and they put it into almost any Mercedes Benz they can get their hands on. So the next model to get this unique motor is the Mercedes SL65 AMG, and it will make its debut at the Geneva Motor Show as the Brabus 800 Roadster.

The SL65 is already unnecessarily powerful when it leaves the AMG workshop in Affalterbach, having 620 horsepower. What Brabus does to this car will not have that big of an effect its performance – usable performance at least – but who doesn’t like more power? Plus, it is just cool to say Brabus 800. That is enough reason to spend half a million dollars on this SL.

With 800 horsepower ad 1,450 Nm of torque (limited to 1,100 to save the gearbox from being torn to pieces), the SL Brabus 800 goes from 0 to 100 km/h in 3.7 seconds, and passes the 200 km/h 9.8 seconds later. Top speed is limited… to 350 km/h!

The car gets a body kit that works brilliantly as far as aerodynamics go, but doesn’t look particularly pretty. It consists of a front spoiler, rear bumper diffuser, and a tail spoiler. There is also a new bonnet with massive nostrils to provide that monstrous engine and its intercoolers with plenty of cold air.

In the chassis department Brabus offers 20-inch monoblock wheels with 255 section tires at the front and 305 at the back, uprated limited slip diff, and tweaked ABC system with 25mm lowered ride height.

The interior is upgraded too, with beige leather and suede, carbon and wood trims, and Brabus logos on the seats and the door sills.
