BMW adds Steam Engine

BMW has added a small steam turbine engine to a prototype 5 series in attempt to improve fuel efficiency. They have been able to increase the fuel efficiency of the vehicle by around 10 percent.

The small steam turbine engine uses excess heat from the exhaust system, to boil a fluid and turn it into steam, the steam then powers the turbine, which then converts the power into electricity which is uses to power the vehicle as well as the petrol engine.
