In response to the World Health Organization’s recent decision to classify diesel exhaust as a carcinogen, more toxic to your health than second hand smoke, America’s largest retailer of diesel passenger cars is questioning the findings.
“After initial review, it is clear that the IARC’s (International Agency for Research on Cancer) evaluations specifically focused on older diesel engine technology, that is, engines that don’t have filter systems and were built prior to the EU4 standard,” said Volkswagen in an official statement. “Currently, automakers in Europe build vehicles to the more stringent EU5 regulations, while diesels in the U.S. adhere to the EPA’s Tier 2 Bin 5 emissions standard that is the strictest in the world.”
According to VW, which just this week announced pricing on it’s latest diesel-powered model, the Beetle TDI, the IARC’s tests are out-dated by nearly a decade. “The engines tested do not represent the current state of diesel technology, which has been available in the market since 2004.”
Newer technologies ranging from improved combustion, to after-treatment exhaust fluid systems to (specifically) particulate filters have, “contributed significantly to minimize particulate emissions,” says VW.
The diesel engine has been a core product in Volkswagen’s powertrain offerings since the 1970s and will continue to be so into the future. “The diesel engine is highly efficient and remains an essential building block in Volkswagen’s drive to reduce CO2 emissions.”
