An environmental group in Europe is saying most of the world's automakers are lying about misreporting emissions and fuel economy on tests that are intentionally unclear and designed with several loopholes for carmakers to exploit.
"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," Greg Archer, clean vehicles manager at Transport and Environment, said in a statement.
Specifically, the Brussels-based group says that Mercedes A, C and E class and BMW's 5 Series cars pollute up to 50 percent more than the automakers report. Emissions claims and real-world emissions for most cars could differ by up to 50 percent by 2020, the group says.
The 18-page report relies heavily on information gleaned from the International Council on Clean Transportation's test that measured emissions from different worldwide vehicles — including Volkswagen's diesel cars and BMW's diesel X3.
In addition to polluting more than the automakers claim — up to 1.5 billion tons of carbon dioxide by 2030, the group says that the additional fuel costs paid by drivers will add up to more than $1 trillion in 15 years.
Transport and Environment said automakers routinely game the emissions system tests by over-inflating tires to create lower rolling resistance, disconnecting the battery to reduce engine load, using unique (or illegal) engine management systems and under-reporting by 4 percent the emissions levels, which is allowable under guidelines.
Both BMW and Mercedes (and others) have denied any wrongdoing.
Basically, it's all made up, according to the group.
