TVR Tuscan 500R

500 hp at the rearwheels in a 1350kg car do mean a couple of things: for starters, it means a 0-60 of 4 sec. and a 300+ km top speed... but (considering it doesn't have traction control or any other electronic safeguards) it'll also mean you're likely to swap ends if you go into a corner too enthusiastically. :p
And that's exactly what this HP2 version does too.
