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.

2017 GMC Acadia adds four-cylinder and All Terrain model

General Motors has officially started the process of updating its long-in-the-tooth fullsize CUVs by unveiling the second-generation GMC Acadia at the 2016 Detroit Auto Show. While the Acadia is 700 pounds lighter, it's also shorter and narrower, which means it's not quite the people mover it used to be. You'll no longer be able to haul eight passengers, although there will still be five-, six-, and seven-passenger offerings. While families might not be thrilled with the loss of a seat, the lighter weight is a net win. Not only will the V6 model feel more powerful and efficient – in addition to the lower curb weight, there's a new, 310-horsepower engine – but it will also likely be more economical. GM estimates the front-drive V6 will return 25 miles per gallon on the freeway, compared to 24 mpg for the current front driver, but city fuel economy remains pegged at 17 mpg. In a move we're not entirely sold on, though, the Acadia will also adopt a four-cylinder engine, and no, it's not GM's highly regarded 2.0-liter turbo. Instead, you'll be able to order this 4,000-pound CUV with a 2.5-liter, 194-horsepower four-cylinder. What it won't be able to provide in straight-line speed, it will make up for with fuel economy. GM is wagering the front-drive, four-cylinder Acadia will net 22 mpg in the city and 28 on the highway. Both engines are paired with a HydraMatic 6T75 six-speed automatic. A new All Terrain model is said to be optimized for wet, snowy and icy conditions, and its drive mode selector removes the Off Road selection in favor of All Terrain. We have live images of both the new Acadia Denali, as well as the new-for-2017 All Terrain model, direct from the floor of the 2016 Detroit Auto Show.

2017 GMC Canyon finally goes Denali

You knew this was coming and perhaps you've been waiting for it: the GMC Canyon dressed up in Denali trim. Even though we're getting to see it before its reveal at the LA Auto Show, you'll have to wait roughly one more year to take delivery since it doesn't go on sale until "late 2016." You can spec the trim on the crew cab models with either the 3.6-liter gasoline V6 or the 2.8-liter diesel engine. You know the formula, and it works well on the Canyon. There's a chrome grille, chrome trim around the foglights, chrome side steps, one polished exhaust tip, a spray-in bedliner, and 20-inch ultra-bright wheels. You can get the rest of the truck done up in one of six colors, two fewer than are available for non-Denali trims. The inside comes in Jet Black only, with heated and ventilated front seats, Denali badging, and a unique instrument panel. Check out the press release below for more info, we'll have live images from LA soon.
