The Flatmobile recently entered the Guinness Book of Records as the lowest street legal car: the car is only 48 cm in hight! The Flatmobile was built by Perry Watkins, a huge fan of the ’60s Batmobile (this is also where the name comes!) The car is powered by a jet engine fitted behind the internal combustion engine at the very rear of the car. It is a home built gas turbine jet engine based around a Holset 685 turbocharger from a Volvo FL10 lorry.
