Nissan has unveiled its first affordable, zero-emission car. Designed for a lithium-ion battery-powered chassis, Nissan Leaf is a medium-size hatchback with a range of more than 100 miles.

It is expected to launch in Europe as well as Japan and America in late 2010.

Pricing will be announced closer to start of sales. However, Nissan said it expects the car to be competitively priced against well-equipped C-segment vehicles.

The company added that Leaf should qualify for local, regional and national tax breaks and incentives in markets around the world.

Nissan president and chief executive Carlos Ghosn said: “We have been working tirelessly to make this day a reality – the unveiling of a real-world car that has zero – not simply reduced – emissions.

"It’s the first step in what is sure to be an exciting journey – for people all over the world, for Nissan and for the industry.”
