Sir George took a spin round Parliament Square in the G-Wiz, a new electric car.
"I was told it uses less energy per mile than any other car on the road, and about a quarter of the energy of a typical small car. 30p of electricity fills up the tank and enables you to drive about 50 miles. It has no emissions, and at £4500 plus VAT for 3 years it is probably one of the cheapest cars on the road. It is exempt from the congestion charge and has Group 1 insurance."
While impressed by the car, Sir George will not be buying one yet. He bicycles to and from work in London.
