A modern car now consumes on average 39% more fuel than specified by the manufacturer
The actual fuel consumption of new passenger car models increasingly differs from the official specifications of the manufacturers.

The work is related to the emissions testing on three vehicles of different technology, all of which Euro6d-temp compliant, and under various driving conditions, both in laboratory and on-road.
The report shows that the CO2 emissions gap between the independently performed WLTP and NEDC tests is small, and suggests the new WLTP test procedure is likely not sufficient to reduce or close the gap between official and real-world CO2 emissions. The report also stresses the lack of transparency about vehicle data, which complicates the analysis of independent tests and makes possible cheating harder to detect.
The new Worldwide Harmonised Light Vehicle Test Procedure (WLTP), designed to improve cars CO2 emissions testing in laboratory, will not stop carmaker manipulation of test results and will not close the gap between official and real world figures a new report by Transport & Environment shows.
“The growing gap means consumers spend a lot more money on fuels than anticipated. According to studies by our members, motorists pay in average an extra 400€ per year for fuel”
Provisional data for European new car carbon emissions in 2017 published today shows the small but expected rise in new car CO2 emissions of 0.4g/km is due to the strong growth in sales of crossover and SUV models – mainly diesel powered.
