The Frankfurt show sees the unveil of the BMW i8. Like that other endlessly teased petrolelectric supercars, the Porsche 918, we've seen concepts, driven prototypes, and now get the real thing. It's coming in April, at about £95,000. And it's claimed to have on-road performance to match an M3 or base 911

The interior's also strikingly different from mainline BMWs. It runs glass-cockpit all-screen instruments and very thin, light seats to emphasise the featherweight engineering that's needed to keep the weight under 1500kg despite the battery.
