Just came accross this pretty cool video of a tour of the
Koenigsegg factory. There is a mixture of assembly, showroom, track and burnouts:
You'll notice two very intersting cars in the video; the Agera and the CCXR. If your not familiar with them the CCXR is a supercharged 1000bhp monster with a top speed of 249mph and a 0-60mph time of 3.2 seconds. The Agera is a little less fast (can't possibly say slower when it comes to these cars) with 900bhp, a top speed of 242mph but a faster 0-60mph time of 3.1 seconds.
Although it did not feature in the video it is worth mentioning the Agera R. A new ethanol powered car with a 5032cc Twin Turbo V8 engine producing 1100bhp in a carbon fibre body allowing it to achieve a 0-60mph time of 2.9 seconds and a top speed of 275mph. All of this is according to Koenigsegg but if the stats are verified it will make the Agera R faster than the Bugatti Veyron, the Henessy Venom, and a whole load of other supercars.
