1. Suzuki Ignis 1.2 SVHS

True MPG: best and worst cars revealed

Official fuel economy: 65.7mpg; True MPG 59.6; Shortfall: 9.3%

Another Suzuki, the Ignis, is the most efficient car we've yet tested. There's plenty to like about this miniature off-roader, including its low price and generous standard equipment. The 1.2 SVHS model has a small electric motor which helps the engine, allowing you to use less revs and consequently less fuel, particularly around town.

The least fuel-efficient car tested:

Audi SQ5

True MPG: best and worst cars revealed

Official fuel economy: 33.2mpg; True MPG: 24.6

This sporty version of the Audi Q5 is properly fast and handles well, but its turbocharged 3.0-litre V6 petrol engine is so thirsty that you'll spend almost as much time at the pumps as you will enjoying its heady performance.
