The 4.5-litre V8 produces 597bhp at 9000rpm, its 133bhp-per-litre made possible by a staggering 14:1 compression ratio. This greater output is pushing 90kg less too, thanks to a carbonfibre underbody, thinner glass for windscreen and side windows, a Lexan engine cover, new and lighter ceramic brakes, forged wheels and an interior of delicious minimalism.
