Porsche and BMW unveil hybrid supercars - Porsche 918 Spyder & BMW i8



Supercars are not usually known for their fuel efficiency, but both Porsche and BMW have debuted hybrid vehicles that are less thirsty at a petrol pump than a Toyota Prius.

Unveiled at the Frankfurt Motor show, the Porsche 918 Spyder can reach 60mph in less than 2.8 seconds, while BMW's futuristic i8 takes less than 4.4 seconds to reach the same speed.

But the sleek sports cars are designed to be fuel efficient as well as fast. Porsche's Spyder can also do 72 miles per gallon and is almost a third more fuel efficient than the Toyota's Prius, while the BMW i8 is even less thirsty as it can manage 113 miles per gallon.

When let loose around the famous racing circuit, Porsche said that the 918 Spyder completed the 12.8 mile track in just six minutes and 57 seconds.

The futuristic BMW i8 is the car manufacturer's 'most advanced' sports car ever and is powered by a relatively small 1.5 litre turbocharged engine which, combined with an electric motor, generates 362 brake horsepower.

This gives the plug-in hybrid a 0 to 62mph time of just 4.4 seconds and an electronically limited top speed of 155mph.
