The same researchers who exposed Volkswagen for using a cheat device on millions of its vehicles claims Fiat Chrysler’s EcoDiesel V6 engine emits much more nitrogen oxide emissions than allowed.
According to Bloomberg, the West Virginia University’s Center for Alternative Fuels, Engines and Emissions found that the 3.0-liter EcoDiesel V6, which is found in the Jeep Grand Cherokee and Ram 1500 pickup, is producing 20 times more nitrogen oxide emissions than is legal. Similar to VW’s cheat device, the Grand Cherokee and Ram 1500 vehicles tested emitted much more NOx in on-road scenarios than in laboratory tests.
“We saw emissions results in simulated on-road cycles on chassis dynamometers that were much lower than the actual on-road results were, suggesting that the vehicle was controlled in different fashions,” Daniel Carder, director of the center, told Bloomberg.
FCA said the study “appears to have been commissioned by a plaintiffs’ law firm for purposes of litigation.” The automaker said it would like to know more about how the research was conducted and noted that the researchers came to their findings by driving faster and carrying more weight in the vehicle than lawmakers require. FCA also said “there is no regulatory protocol for conducting on-road emissions testing.”
