All it takes is one automaker to make it harder on everyone else, and that’s exactly what Volkswagen has accomplished. The first set of diesel vehicles that are going under the EPA and CARB’s microscope are the GMC Canyon and Chevrolet Colorado. Both trucks can’t be certified by the federal agency until they go through tests not only in a lab, but also on the road.
The big thing that the EPA and CARB are looking for, of course, are any defeat measures that make the trucks look like they pollute less. GM claims that it hasn’t engaged in the kinds of practices that VW was up to, and soon enough we will all know if that’s genuinely true. If no such measures are found, then the Canyon and Colorado will be certified by the feds and everything will be fine.
Truck shoppers who have eagerly been awaiting the launch of the diesel versions of the Canyon and Colorado might have to wait a little longer. Even though both models were set to launch in the fourth quarter of 2015, the additional EPA testing could go on long enough that the vehicles don’t hit dealerships until the first quarter of 2016.
A report from Automotive News said that it’s uncertain if the EPA and CARB are conducting their tests congruently or not. At this point, it seems the feds aren’t interested in disclosing too many details about their testing methodologies, maybe in part so that automakers are clueless about how to create workarounds and game the system once more. Another possibility is that regulators aren’t entirely sure which testing methods they want to stick with in the long run, so they’re trying out a few to see how they work.
General Motors claims to have conducted extensive emissions tests both in the lab and on the road to ensure both pickup trucks meet all federal standards. Engineers had to outfit both models with additional equipment not used in other global markets.
