This car has been misidentified as an Audi R8 for the last couple of years on the internet. The car is actually a Norma M20 with a 3.0 liter straight-6 BMW M3 engine putting out approximately 400 hp. The entire car weighs 605kg (1334lbs). It is quick, very quick. Here's a link to the driver/owner's personal website. Note that the car is for sale.
