On average across the model years we cover, diesel returns about 32 mpg (UK), petrol (regular) returns about 31 mpg (UK), petrol (premium) returns about 26 mpg (UK) on each vehicle's most efficient configuration. Averages depend on the mix of vehicles in each group, so compare like-for-like models.
Where do the fuel economy figures come from?
US EPA fuel economy data from fueleconomy.gov, converted from US to UK miles per gallon. Real-world economy depends on driving style, load, weather and maintenance.
