Avoid London's congestion charge
Hi-tech engine won't appeal to all
This is the future for petrol cars (or not): a conventional petrol engine linked to an electric motor. The battery is charged when you're coasting or braking and fed back to the engine under acceleration; it's essentially free power. It may have a conservative look, but there are many innovations (as well as the engine), such as a natural driving position, roomy interior and clear dash.
