The Mercedes-AMG SL 63 Roadster is something only AMG would be capable of doing. Once the Biturbo V8 engine has been revved up, the roar of its 585 hp is enough to tell you what is about to happen: one simple push of the accelerator and this two tonne beast of a car will go from 0 to 100 km/h in less than 4 seconds. Its top speed has been limited to 250 km/h, but the “AMG Driver” option can push that up to 300 km/h, for those who want it!
