Find the most fuel efficient, and so lowest CO2-emitting, new car with the help of this
ACT ON CO2 search tool, created in association with What Car?
Simply select the category (supermini, small family, executive and so on), fuel type and gearbox that meet your needs, hit submit, and you’ll be returned the 10 most fuel efficient cars in the category. Each entry on the top 10 list is colour-coded to reflect the Fuel Economy Label (a label much like the one seen on fridges and washing machines).
Good luck with your search!
