The BMW i8 - a sporty, hybrid all-rounder

While the i3 is best suited to round-town usage, the i8 has broader ambitions. It uses the same electric motor as the i3, this time mounted over the front axle, in conjunction with a three-cylinder, 220 horsepower petrol engine over the rear axle. Combined, you're looking at a 354 horsepower all-wheel-drive with 550 Nm of torque.

All wheel drive isn't entirely accurate though - the i8 constantly proportions the power between the front and rear drive systems according to how the car is being driven. With a much smaller battery system than the i3, the i8 can only manage around 35 km (20 miles) in fully electric drive mode - but then, that would cover an emission-free commute for the majority of people.

The real value of the hybrid system comes with longer range driving, where on the EU cycle, the i8 manages a whopping 104 miles per gallon (2.7 liters per 100 km). Driven hard, the fuel consumption will double, but don't forget that the Toyota Prius is advertised as a 50 mpg hybrid and is nowhere near as much fun.

Like the i3, the i8's top speed is electronically governed, but this time at a very sporty 250 kph (155 mph), so it'll hold its head high on any autobahn. The i8 will hit 100 kph (62 mph) in a brisk 5 seconds or less, decent sportscar territory there, and the car's entire underbelly is totally enclosed to boost aerodynamic efficiency and reduce fuel consumption.
