The industry grapevine suggests Lotus has struck a deal for the Esprit to use BMW's legendary 400bhp 4941cc V8, from the E39 M5 – an engine with response and torque rust so intoxicating that some pine for it even after sampling the latest M5's 500bhp V10. In the BMW, the V8 produced 400bhp. But it's hugely tunable – Ascari has ramped peak power to 500bhp in its KZ1.
