Fuel economy: Real-world miles per gallon information now available

We’ve all done – got to the end of a long journey and wondered where the fuel has gone.

Testing for actual mpg

Testing for actual mpg

And no you probably haven’t made a miscalculation because the published fuel economy figures which you use for the trip are quite often nothing like you will get in ‘real world’ driving.

That’s going to change now with the launch by What Car? of their True MPG which aims to give Britain’s car buyers the most realistic fuel economy information possible.

Their test cars use real roads in exactly the same conditions that every motorist faces every day to find out the vehicle’s true fuel economy.

Until now, the only information that’s been available is the car makers’ own figures, which are determined under EU law and are conducted in laboratory conditions on rolling roads.

Not any more. Car buyers can log on to www.whatcar.com/truempg and work out the fuel economy they can expect to get from their next new car.

The mag’s editor-in-chief Chas Hallett said: “With rising fuel prices, the miles-per-gallon issue is high on every motorist’s agenda. Countless car buyers are frustrated that they don’t match the official government fuel figures. True MPG will allow motorists to select a car personalised to their driving needs and budget. We hope that it will become invaluable in the complex and emotional car-buying process.”

Just to give you an example of some of the fuel economy variations I’ve gone through their list and selected these as decent examples (the average fuel economy variation appears to be 10-20% on the published figures though the ones below are obviously greater).
