A new study from Transport & Environment shows that several major automakers are providing inaccurate economy ratings of some of its petrol models.
The Belgian-based T&E research group states that there’s a big gap between real-world mileage and factory provided fuel consumption information. In fact, some of the tested models burn more than 50 percent more fuel than claimed.
Mercedes-Benz cars have the biggest average gap with real-world fuel consumption exceeding test results by nearly half. As biggest cheaters the group is pointing the A-Class, C-Class and E-Class models, while the BMW 5-Series and the Peugeot 308 are just below 50%. The Volkswagen Golf with its TSI engines stands at around 40% gap. Also, none of the improvement in emissions measured in tests of Opel/Vauxhall cars since 2008 has delivered improvement on the road and actually their real-world fuel economy is getting worse.
Greg Archer, clean vehicles manager at T&E, commented: “Like the air pollution test, the European system of testing cars to measure fuel economy and CO2 emissions is utterly discredited. The Volkswagen scandal was just the tip of the iceberg and what lies beneath is widespread abuse by carmakers of testing rules enabling cars to swallow more than 50 percent more fuel than is claimed.”
