This new one, called Onyx is the most radical yet, though – a 600hp 3.7-litre V8 mid-engined diesel hybrid car with a carbon fiber chassis and a kerb.
KERS-style brake energy harvesting delivers and extra 80hp under acceleration, via lithium ion battery-powered electric motor. The flat carbon fibre floor generates ground effect, so minimising external wings. There’s a op-up rear airbrake. Discs are carbon composite all round while both the rear-drive engine and the double wishbone suspension with inboard control are both designed by Peugeot Sport.
