Car magazine What Car? is launching a new feature which will determine real world fuel economy on new cars.
The move comes as many motorists feel that the manufacturers’ quoted figures are unachievable. This is because the official figures are conducted in laboratory conditions on rolling roads.What Car? True MPG will test cars on real roads in exactly the same conditions that every motorist faces every day. Car buyers can simply log on to www.whatcar.com/truempg and work out the fuel economy they can expect to get from their next new car.
Commenting on the project, What Car? editor-in-chief Chas Hallett said: “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.”
What Car? tests the vehicles using a portable emissions-measurement system when the engines have reached normal operating temperature. The vehicles are then driven by two experienced engineers over a variety of roads including motorway, A- and B-roads, and through towns and villages. The data from the testing considers driving style, changes in altitude, ambient temperature and humidity and engine temperature.
