Who owns it? Prince Charles

The vintage gas guzzler (a present from the Queen on his 21st) has been given an eco-friendly twist.

It runs on white wine biofuel, extracted from the local vineyard's surplus booze stock. It works out at £1.10 per litre - a price fit for a king.

Only 140 convertible Volantes were built, complete with 4.0 litre engines a top speed of around 150mph but thanks to the more efficient biofuel it can set the needle back to 165mph!
