GM diesel pickups first to undergo extra EPA, CARB testing

The effects of Volkswagen's long-running diesel emissions evasion are starting to spill over to other automakers, but General Motors is taking things in stride. The 2.8-liter, four-cylinder Duramax in the 2016 Chevrolet Colorado and GMC Canyon is the first engine to get extra scrutiny by the Environmental Protection Agency and the California Air Resources Board, Automotive News reports. Rather than just the usual in-lab test, it's also being checked on the road. However, the extra evaluation shouldn't have any impact on when the trucks with his mill hit dealers later this fall. "We're in our final stages of the EPA certification, and our launch is on track," Chevy spokesperson Otie McKinley tells Autoblog. The four-cylinder diesel in the trucks makes 181 horsepower and 369 pound-feet of torque, and the automaker is touting low NOx production. In the announcement for the Colorado's specs, the company calls it "the cleanest diesel truck engine ever produced by General Motors." The tech includes exhaust gas recirculation to lower combustion temperatures and improve emissions. There's also a urea tank like on the bigger diesels for full-size trucks, and it gets refilled in time with oil changes. An indication on the instrument panel lets drivers know when that's needed, too. Even with the more demanding testing, the company doesn't seem too worried about the four-cylinder passing. "Part of our development process is on-road and off-road [laboratory] testing," Scott Yackley, Chevy Trucks assistant chief engineer, said to Automotive News. In the wake of the VW scandal, the EPA has pledged more rigorous testing. Before, on-road emissions evaluations were largely limited to heavy-duty vehicles, but the agency has decided to apply the checks more often to other models. There's also now greater cooperation with Canadian authorities.

GMC doesn't care if it's Mt. McKinley or Denali

GMC is getting a mountain of free publicity from President Obama's decision to rename the former Mt. McKinley back to Denali in Alaska. The truck-and-SUV brand is happy to see the moniker of its high-end trim in the news, but doesn't intend to change any marketing because of the switch. "It had no impact or change on our strategy," a GMC spokesperson told the Detroit Free Press. The brand doesn't expect sales to change, though the frequent use of the word Denali in the news in a positive light amounts to free, albeit temporary, advertising for the company. Denali is the word for the nation's tallest mountain in the Koyukon Athabascan language, and it means "the high one." In 1896 a prospector rechristened the peak Mt. McKinley to support presidential candidate William McKinley. He won the election, but was assassinated in 1901. The title stuck, and the site officially got the name when a national park was created there. Since then, there has been a push to return to the original moniker, and according to the Free Press, the park became Denali in 1980. Now, the peak has followed suit. GMC started using Denali to denote the top models on the 1999 Yukon. Today, it's available as an upmarket alternative on most of the brand's lineup.

GM mulling off-road variants of fullsize SUVs

According to General Motors, owners "just love off-roading with [its fullsize body-on-frame sport utility vehicles]," namely the 2015 Chevrolet Tahoe and Suburban and GMC Yukon. If that's the case, it's a bit odd that sales of the previous generation of these models with the Z71 off-road package didn't sell particularly well.
Perhaps, considering this disconnect between owner's thoughts and desires with actual sales, it's not surprising that General Motors is reportedly "considering" an off-road specific model. That means the package would include styling changes and badges along with suspension modifications and larger wheels with appropriately sized fender flares.
There's no indication if the off-road model would be called Z71 or when it may potentially go on sale, assuming it ever goes on sale at all.
