With a score of just 19 the Veyron is one of the least environmentally friendly cars available today. But is that really a surprise? The car is designed to break world records with its quad-turbo W16 engine that makes 1,000 hp (or more depending on the configuration). But when it comes to matters of the environment, the numbers are far lower: the Veyron has a combined fuel economy rating of just 10 MPG.
