Superlight micro-engine that weighs just 22lbs and is the size of a BACKPACK is powerful enough to drive a Ford Fiesta for 750 miles without refuelling

A hyper-efficient and super-light one-piston engine smaller than a backpack could render modern hybrids obsolete.

Shaul Yaakoby, 53, is the engineer from Tel Aviv, Israel, that developed the engine and claims it is capable of churning out enough horsepower to run a small hatchback for 750 miles (1,200 km) without refuelling.

The engine, manufactured by firm Aquarius Engine, is made of a only a dozen moving components.
