The diesel emissions scandal has obviously prompted authorities directly responsible for enforcing standards to pay more attention during their testing of new vehicles. GM’s new batch of oil-burning pickups have now gone under the magnifying glass like never before, according to a report published by Automotive News.
It says GM was informed that the new Chevy Colorado and GMC Canyon diesel variants would not receive certification until they underwent both lab and real world testing. This could potentially delay their Q4 2015 introduction, says the source.
Scott Yackley, the assistant chief engineer for Chevrolet Trucks confirmed the new on-road testing procedure that will be intorudced.
He said “the EPA and CARB told us they are going to do on-road testing,” but that they are confident no problems will be discovered as they do test their vehicles for emissions and efficiency outside the lab (apparently).
So expect possible delays to the previously announced showroom debut date for the two models.
