Mitsubishi Colt: clean ClearTec
A smartly put together green super-mini
The Colt's Auto Stop & Go system is smartly executed. It means that the ClearTec is cleaner and more economical than the standard Colt 1.3, yet it offers better performance. There are greener super-minis available, such as the oil-burning Ford Fiesta ECOnetic, but the petrol-powered Mitsubishi costs less than its rivals, and it won't sting you with diesel prices at the pumps, either.
