There have been many green cars in the past, but paint colour isn't what springs to mind with that phrase these days. Now it's all about being cheap to run, with higher mpg figures, lower exhaust emissions and reduced carbon footprints. There's a lot of pressure on the manufacturers of modern cars to go green - and many are stepping up to the plate.
