Chevy Colorado Diesel Under the EPA’s Microscope

Chevy Colorado Diesel Under the EPA’s Microscope

General Motor’s new diesel-powered small pickups will be scrutinized by the Environmental Protection Agency (EPA) before they are released for sale as a result of the Volkswagen diesel emissions scandal. 

“The EPA and CARB told us they are going to do on-road testing,” Scott Yackley, Chevrolet Trucks assistant chief engineer, told Automotive News. The trucks will not be certified for sale until they are tested on road by the EPA to make sure that the new 2.8-liter diesel engine passes emissions tests during normal everyday use.

This could result in the trucks hitting the market slightly later than the fourth quarter of this year, the planned on-sale period.

This is the first example of more stringent testing measures being introduced by the EPA. The agency says that it will begin testing cars on road, rather than just in a lab. They will also test cars from personal owners and from rental car fleets, so that they aren’t specially prepared by the automaker.

Volkswagen admitted to installing defeat devices in 11 million diesel vehicles which were able to detect emissions testing, and automatically make the engine omit less pollution for the duration of the test. During everyday driving, those cars were polluting 10 to 40 times more than the EPA allows.

Yackley says the GM is confident that the trucks will pass the test. “Part of our development process is on-road and off-road [laboratory] testing,” he said.
