Believe that what ever I am on is very crazy stuff. I think its bottled HSV exhaust fumes or something

Back to the inferior R8 and HSV GTS, the holden is not only cheaper but it comes very close in terms of 0-100 km/h :
HSV GTS VS VAG Typ42 (Yes, its a VAG with a silly Typ number - go Nazis)
4.96s VS 4.6s
325kW VS 309 kW
HSV claims the braking performance of the GTS is better than some of the world's leading sports cars, including the BMW M5, Mercedes-Benz AMG CLS55 and Lamborghini Gallardo. The GTS can stop from 100 km/h (62 mph) in just 36 metres, only 30 centimeters shy of a Porsche 997.
