What a good idea.
New MPG database challenges 'wildly optimistic' official figures
Disappointed that your new car can't match the manufacturer's claimed fuel consumption figures? You're not alone – now Honest John has the answer.
Honest John's 'real life' MPG register aims to reveal the true fuel consumption of cars
A new "real life" MPG register aimed at revealing the true fuel consumption of cars has been launched.
Devised by The Daily Telegraph's Honest John, the new database will challenge the wildly optimistic figures that motor manufacturers are obliged to publish.
The Real Life Fuel Economy Register enables motorists to register the fuel economy they are achieving in their own cars, in day-to-day driving, and the database is broken down into make, model, engine and transmission type.
Each time a motorist enters an average fuel consumption figure the overall average will self-adjust to reflect it. The figures can then be directly compared to official EC figures.
"Different types of driving and usage and the experience of thousands of drivers all average out to give an overall figure that you can reasonably expect to achieve," said Honest John.
The website incorporates software that will bar multiple entries, overly optimistic entries or what HJ calls "other forms of sabotage".
Hoenst John states that EC figures are over-optimistic because they result from laboratory tests carried out to simulate a mix of different types of driving, arriving at a "combined" CO2 emission and fuel consumption figure. But because vehicle taxation in Europe is based on CO2 emissions, manufacturers optimise their engines to achieve the lowest possible CO2 in the tests, even though these might not reflect real-life motoring.
"This gives a correspondingly low fuel consumption figure," says Honest John. "Unfortunately the relevant EC Directives prescribe that this figure and only this figure can be publicised by manufacturers, even though it is unlikely to be achieved by the average driver in real life conditions."

Do you let her take it or go out and find it gone??
I have to force her out of her ML when I need to carry something big...or something with 4 legs...or both!
