Chevrolet Colorado Diesel to Get Extra Attention From EPA and CARB

It was only a matter of time before regulators decided they'd best take a closer look at diesel vehicle emissions claims and it looks like the Chevrolet Colorado is the first on their list. Both the EPA and the California Air Resources Board (CARB) notified General Motors that the new diesel Colorado won't be certified until it has been road tested and lab tested. GM has plans to start selling the car in the fourth quarter so the extra testing has the potential of delaying the truck's on-sale date. According to Automotive News, Chevrolet Trucks assistant chief engineer Scott Yackley confirmed the on-road testing requirement at a media event for the truck.

The EPA previously announced that it would be conducting more stringent emissions testing in both the lab and on the road in an effort to prevent cheats of the type Volkswagen used on some of their vehicles. CARB will also be doing additional on-road testing, but it's not clear if that will be done separately from EPA testing. The Colorado in question has a 4-cylinder diesel engine that will also be in the GMC Canyon and has already been used in the global market. Those engines didn't have some of the emissions equipment required in the U.S. inlcluding the Selective Catalytic Reduction system. This sprays urea fluid into the exhaust system to reduce emissions. GM is confident its trucks will come through testing without trouble. RELATED: 2.1 Million Audis Found With Defeat Devices, Let the Lawsuits Commence
