The Geneva Motor Show has yet again served as a haven for automotive tuning companies, fighting among themselves for horsepower supremacy.

Brabus is of course one of the biggest names in the business, and if you’re any sort of Mercedes-Benz fan, you know that that seeing that big ‘B’ logo means you’re dealing with a bunch of very fast, menacing-looking luxury cars. The very tip of the spear, if you will.

To us, the tuner’s three meanest saloons are what stood out most in Geneva, and kicking things off is the Mercedes-AMG E63 S in Brabus 800 spec.

This bad boy of a midsize premium saloon is pushing down 800 PS (739 HP) as well as 1,000 Nm (737 lb-ft) of torque, for an electronically limited top speed of 300 km/h (186 mph) and a 3-seconds flat 0 to 100 km/h (62 mph) acceleration time. To put it plainly, there aren’t many four door cars that can keep up with something like this, which is why it costs over €250,000 ($309,700).

Yet, if you’re wondering what on Earth could be better than this savage E63 S, the answer is that very same Brabus 800 kit, installed on the Mercedes-AMG S63 S. While you might think that this wouldn’t be as quick as the E63 S, and technically you’d be right, the difference is, simply put, insignificant.

The S-Class-based Brabus 800, with the same amount of power and torque as the E-Class we just talked about, will hit 100 km/h (62 mph) in 3.1 seconds and max out at the same 300 km/h (186 mph) as its smaller sibling. So you basically get more car than you do in the E63 S, and with similar straight line performance. The only negative is the €359,000 ($444,000) price tag.

Last and most definitely not least is the Brabus 900, which is based on the updated Mercedes-Maybach S650. This full-size limo is powered by a modded twin-turbo V12, massaged to deliver no less than 900 PS (888 HP) – it’s enough to get it from a stand still to 100 km/h (62 mph) in just 3.7 seconds, while the top speed is in excess of 349 km/h (217 mph).

All three models are also equipped with the tuner’s body kits and customized interior designs.
