4. Lightning GT

4. Lightning GT

An electric car with the equivalent of 700bhp, four-wheel drive and a 0-60mph time of four seconds might do more to sell the idea of eco-motoring to petrolheads than anything that's gone before.

That is if we ever see the Lightning GT on the road. Unfortunately, the makers of this fine-looking car still need massive investment before they can give the go-ahead for production.

The GT has motors in each of its wheels - effectively making it four-wheel drive - and a regenerative braking system to help recharge the batteries.

Weight-saving technologies include the use of a spaceframe chassis and carbonfibre, and Kevlar body panels. Features include traction control and a home charging system.

Lightning hasn't yet confirmed final specifications or pricing, although a price tag of around 150,000 is expected.

When's it due? sometime in 2010
