Daihatsu's sleek four-seater for British motor show

Daihatsu will show off what it claims is the world’s most aerodynamic four-seater at this month’s British motor show: the UFE2, with a drag coefficient of 0.19 Cd.

Its name stands for Ultra Fuel Economy, and the petrol-electric hybrid was first shown at last year’s Tokyo Motor Show. The teardrop-shaped mini is made from aluminium and composites, and weighs just 570kg.

Thanks to the 660cc direct-injection petrol engine, boosted by an electric motor, economy is rated at up to 170mpg.
