Top 100 most fuel-efficient cars

Want to save fuel and cut down your CO2 emissions? The DTI has just unveiled the “Act On CO2” initiative to encourage car buyers to purchase more fuel efficient motors. Auto Express has conducted its own research to find Britain’s 100 most economical motors.

The tests were conducted on public roads and take into account traffic conditions, weather, types of road and all the other variables that influence your mpg. Ten classes of cars were tested, from city cars to SUVs and family saloons to MPVs.

Of course SUVs don’t have the best reputation among the environmentally conscious, but as you can see below only one of our top ten failed to top 30mpg. Top performer was the Honda CR-V, which uses the same engine as the Accord that won our family car class. It returned 36.4mpg.
