2006 Brabus SV12 S Biturbo Roadster

The main reason for the less than stellar 0-60 time is due to lack of traction. The problem with the 65 series amg's and highly tuned versions of the same engine, without slicks its hard to get the power down and once you do have a significant amount of grip you're already into 3rd gear and above. In a car like this 0-60 is not so significant as 0-300km.

With that power it should do a 0-100 in 3 seconds, easy, but it does not?

It has 537kw/730PS and the torque is limited to 1100 Nm.
