D he Chevrolet Colorado and its identical brother GMC Canyon belong to the Class of mid-size trucks and thus one of the little pickups that are actually not very popular on the US market. In addition to the classic gasoline engines, a 200 hp 2.8-liter four-cylinder turbo diesel has also been used in the Colorado and Canyon since 2014. And that's exactly what GM wanted to have certified for the 2016 model year.
EPA sees no suspicion of manipulation
Warned The EPA is now acting more cautiously on the VW emissions scandal involving manipulated diesel engines. US media write that GM does not want to assume any intention of manipulation, but the truck should still prove itself in emissions measurements in real road traffic and thus underpin the test bench results. The diesel in the pickups works with urea injection for NOx treatment.
GM sees the market launch of the diesel models at risk due to the extensive emissions test. Actually, the diesel should have come on the market from the fourth quarter of 2015.
