Believe it or not this stunning Porsche is capable of 94mpg! On display for the first time at the Geneva Motor Show, the 918 Porsche Spider is a mid-engined sports car, that also utilises plug-in hybrid technology. However, this does not mean performance has been compromised, as the car can hit 62 mph in just 3.2 seconds and goes on to 198 mph.

One of three new hybrid Porsches making their debut in Geneva, the 918 will not go into production but the company says the car points towards the marque's future use of hybrid technology, which is already used on the Cayenne.
