Last week, we told you about Brabus’ latest creation, called the SV12 R Biturbo 800. They claimed it was the world’s fastest sedan, but as TopGear.com points out, it isn’t actually.

Based off the Mercedes-Benz S600, the Biturbo R 800 has a top speed of 217 mph. However, tuner G-Power strapped some turbos to the BMW M5 some time ago, creating the G-Power Hurricane RR. That managed to achieve a top speed of 231.2 mph, quite a lot quicker than the Brabus.

So is it at least the most powerful sedan in the world? Well, not if we’re going by horsepower. The G-Power Hurricane RR develops just as much as the Brabus, 800 metric horsepower. However, if we’re going by torque, the Brabus develops 811 lb-ft, while the G-Power makes do with 590. The result of that is a 0-100 kph time of 3.9 seconds for the Brabus, while the Hurricane does it in 4.35 seconds.

So have your pick: top speed or acceleration. I think I’ll opt for the latter.
