Finally, An Alternative To Nonsense ‘Official’ MPG Figures

Filling up car with fuelUK drivers could save up to £4.45 billion per year on fuel if their cars were able to match the official fuel consumption figures.

Unfortunately, in real life driving conditions, most cars fall badly short of these optimistic laboratory-tested figures — according to new research published by motoring website, the average car achieves just 88% of its official mpg figures.’s Real MPG database now has 32,000 entries from people who have recorded their cars’ fuel consumption and shared this information with the internet community.

The results are interesting and quite surprising -while some cars perform very badly, some even manage to beat their official figures.

In each case, the percentage number relates to how close the car gets to its official mpg figures — a number over 100% means that the car does better than the official figures.

Top 5 performing cars                                Real MPG Ratio

1.Land Rover Defender (1984-)                        105.4%
2.Toyota Celica (2000-2007)                          103.8%
3.Jaguar S-Type (1999-2007)                          103.6%
4.Nissan Micra (2003-2010)                            102.2%
5.Honda Civic Type R (2007-2012)              102.1%

Bottom 5 performing cars                           Real MPG Ratio

1.Mercedes-Benz B-Class (2005-2012)        71.2%
2.Lexus CT200h (2011-)                                    73.0%
3.Range Rover Evoque (2011-)                       73.4%
4.Vauxhall Astra Sports Tourer                      74.0%
5.Audi A1 (2010-)                                                 74.2%

There doesn’t really seem to be any pattern to the best and worst cars — they include large, small, luxury and mass-market vehicles from manufacturers in Europe and Asia.

As Honest John comments:

“Given the ever-rising fuel prices, the Real MPG provides a tangible service for motorists. This information allows car owners and buyers to make accurate predictions as to how much fuel they will use, and be better prepared as to how much that will cost. It’s also important to remember that a car’s fuel economy does vary considerably due to several factors: driving conditions and driving style.”

It’s worth noting that finding the cheapest locations to buy fuel can help — and while I’m a fan of branded petrol and diesel rather than supermarket stuff, it’s still possible to save pennies and pounds by choosing carefully where to fill up — and make sure it’s on your route, rather than a detour or a special trip.
