Mitsubishi will unveil this new Global Concept Small supermini at the Geneva motor show this March.
The car is expected to go into production in March 2012 and is a little smaller than the Colt it will replace. Even so, Mitsubishi claims the supermini will be able to seat five.
Power will come from a 1.0- or 1.2-litre petrol, and Mitsubishi promises fuel economy of nearly 80mpg and emissions around 95g/km.
The engines will be matched to a regenerative braking system and stop-start technology to improve efficiency, while the car's shape is designed to be as aerodynamic as possible.
Reducing weight has also been a priority, and Mitsubishi says it has reduced resistance in the engine, transmission, brakes and tyres to boost efficiency.
