Chevrolet and GMC the First to Receive Extra EPA & CARB scrutiny on Emissions Testing

Chevrolet is feeling the heat from the backlash of Volkswagen's diesel emissions cheating scandal. The EPA has said that they will begin more stringent testing to insure that vehicles meet the requirement for emissions testing in the lab and on the road.

Volkswagen is being investigated for their practice of installing software that could switch on and off the emissions system so that when lab testing was being done the emissions system was turned on and when it came to the road test the emissions system was turned off which allowed the engines to put out as much as 40 times the legal limit of nitrogen oxide. 

Chevrolet and GMC will be the first to get the extra scrutiny form the EPA and CARB on their new diesel-powered pickup trucks. Chevrolet was told by the EPA and the California Air Resources Board (CARB) that they will not certify any of its new diesel-powered Chevrolet Colorado and GMC Canyon pick-up trucks without having been tested on the road and in the laboratory.

Scott Yackley Chevrolet's Trucks assistant chief engineer stated. "GM engineers have conducted extensive lab and road tests and are confident that the trucks will pass the additional testing. He also said " Part of our development process is on-road and off-road (laboratory) testing.
