Chevrolet Colorado apparently has put themselves into trouble by getting unwanted attention from the regulators. EPA and the California Air Resources Board (CARB) have decided to take a closer look at diesel vehicle emissions claims, and they have notified General motors that the new diesel Chevrolet Colorado will not be certified until it has been lab tested and road tested.
The extra testing has the potential to delay the truck’s on-sale date as GM already plans to start selling the car in the fourth quarter. This news was confirmed by the Chevrolet Trucks assistant chief engineer Scott Yackley during the truck’s media event.
EPA said before this that it would be doing more rigorous emissions testing on the road and in the lab in order to prevent frauds on the type of Volkswagen used on some of their vehicles. Apart from that, CARB is also going to conduct extra testing, but it is unclear whether the test will be done separately from EPA testing or not.
Chevrolet Colorado has a 4-cylinder diesel engine that will be present in the GMC Canyon as well, and it has already been used in the international market. The engines do not have some of the emissions equipment that the U.S needs, including the Selective Catalytic Reduction system. Because of that, the urea fluid needs to be sprayed into the exhaust system to reduce emission.
