Eco-friendly motoring isn't going to fight for top attention among new car releases any time soon, but its solid presence — often right alongside its fire-breathing kin on the showstand — is not just newsworthy, but ever more significant in the face of worldwide eco legislation set to enfoce clean motoring the world over.
