General Motors are making a song and dance about their new $1 billion electric car.

It does a 100mph, but it only has a range of 40 miles, not much use to a chauffeur! Tunbridge Wells to Heathrow is 62 miles, each way so you can see the problem.

To be honest I don’t think we will replace our Mercedes yet, as the only real ‘green’ option is the Lexus hybrid.
