London, England - A British inventor unveils the world's most fuel-efficient vehicle, a three-wheel "TeamGreen" car capable of doing 8,000 miles to the gallon.

The 45-year-old inventor, Andy Green, from the University of Bath, built his budget eco-motor for just ๏ฟฝ2,000, and will be the sole British contender for the title of the world's most fuel-economic car in a global competition being held later this month.

It has taken Mr. Green more than two years to design and build the car, which will be the fourth eco-vehicle he has built. He holds the British record for fuel-efficiency, with 6,603 miles to the gallon in a previous car.

According to the report, the new vehicle is powered by a single cylinder four-stroke engine with a capacity of just 35cc and runs with a special management system incorporating fuel injection.

A spokesman for Bath University says, "Andy Green is keeping the spirit of the lone British inventor who takes on the world very much alive."
