Infiniti Emerg-E concept

Infiniti's third recent concept car, the Emerg-E, will debut at the Geneva motor show next week. Following the Essence of 2009 and last year's Etherea, the Emerg-E is the brand's first mid-engined car design.

What if it's simply some unremarkable supermini – maybe even an electric one?

"Carry-on" engine will power Le Mans racer

NISSAN will this year compete in the famous Le Mans 24-hour race using a revolutionary 1.5-litre, 400bhp engine that’s small enough to qualify as carry-on luggage.

And while the engine block is too heavy to take onto a plane as hand luggage, its 50cm height, 40cm length and 20cm width makes it small enough.
