5. Volkswagen Up 1.0 75

True MPG: best and worst cars revealed

Official fuel economy; 68.9mpg; True MPG 55.9; Shortfall: 18.9%

Volkswagen's city car make a second appearance in the top 10, this time with the less powerful 74bhp 1.0-litre petrol engine. The Up has plenty of virtues, including an upmarket interior and a comfortable ride, and if your top priority is saving money at the pumps this is the version to go for.
