Ford will accelerate electric vehicle development and plans to sell a pure electric car from 2011.

Ahead of the Detroit motor show, which opened to media on on Sunday (11 January), the company said a new electric car would be based on the Focus platform and have a lithium ion battery.

The car would be developed in partnership with Canadian supplier Magna and produced at an initial rate of between 5,000 and 10,000 units a year.

From 2012 the company will launch a new generation of hybrid vehicles with lithium ion batteries. The first of these will be the Fusion and Milan.

In the last five years Ford has sold almost 100,000 hybrid cars.
