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 First Drive

We're in the midst of the Second Great CUV War, and the crossovers are winning by a lot. Compact sedans are being hauled around the side of idled factories and unceremoniously shot. FCA, whose be-sweatered CEO is either omnipotent or a troll of the highest order, is organizing a last stand around profit-dense SUVs and trucks on the off chance that gas prices don't rise ever again. It's the tall wagon's finest hour, and GMC is hoping the new Acadia will capture a share of the glory. The old Lambda-platform Acadia was introduced in 2007, leading the full-size, three-row crossover charge that spawned a quartet of semi-indistinct variants, including a Saturn. (Remember Saturn?) These four were truck-like in heft and capabilities, but lighter and better-mannered than their body-on-frame counterparts – and with an unusually stout 5,000-pound towing capacity. The Lambda siblings bombarded established beachheads on the sales territories occupied by minivans and truck-based SUVs. Last year, GMC moved nearly 100,000 Acadias in the US, the best year ever for the model. Now GMC shows up with a deflated Acadia for 2017, 7.2 inches shorter overall, 3.5 inches narrower, and with a 6.4-inch-shorter wheelbase. The company has even carved something like 700 pounds out of its previously portly unibody, mostly due to the size reduction but also through an increase in the percentage of high-strength steel and the use of lighter soundproofing materials. GM's C1XX platform was launched with the Cadillac XT5 earlier this year, and this GMC version is the second to appear. There's even an available four-banger, but more on that in a bit. What remains to be seen is whether the downsized Acadia represents a leaner, meaner fighter or if GMC is sending it into battle hamstrung. Outside, the new Acadia is stealthily innocuous. Gone is some of the lozenge-ness of the outgoing Acadia, but don't fret about it standing out from the crowd. The overall styling falls into lockstep with the Sierra and Canyon. The cut of the rear window, with an upsweep at the trailing edge, emulates the brand's mid-sized truck offering. A chrome mustache cuts across the front fascia below the grille, and there's more brightwork around the front side windows and at the crease below the scallop in the doors. The taillights are more contemporary than before, with an attractive elongated C element comprised of LEDs.

GMC's Denali offerings are going great guns

The Denali trim that GMC uses to denote its top-of-the-line vehicles was introduced back in 1999, partly as a way to challenge the recently introduced Lincoln Navigator. Fifteen years later, and with GMC the tenth-largest US automotive brand by itself Denali has become a sub-brand that keeps the cash registers ringing at the Renaissance Center HQ. While GMC increased sales by 9 percent in 2013, TheDetroitBureau.com reports that that Denali sales rose by 20 percent.
There are currently five Denali models in the GMC line, with the Denali trim available on all but its commercial vans. In 2010, when the now-discontinued Yukon XL Hybrid was also on sale, GMC sold 32,886 units of its top trim. Last year, that number had increased to 75,558, with almost no help from traditional marketing spends. Go to YouTube and search for "GMC Denali commercials" - the few actual commercial results are from years ago. GMC marketing director Roger McCormack tells TheDetroitBureau.com, "It's largely all been organic."
As sales have grown, so has the tide of money GMC rakes in from the additional luxury features on Denali models. The 2015 Chevrolet Tahoe starts at $44,600, yet its 2014 Yukon Denali doppelganger starts at $58,320, pricing that includes additional features like the larger 6.2-liter V8, nicer interior, head-up display and magnetic ride control suspension. The Yukon XL Denali starts at $60,965, but the article says the "average customer" likely to spend "up and above $70,000" to take one home. How does that happen? On a top-trim Tahoe LTZ, the top-tier wheel option is a set of 20-inch chrome wheels for $400; on the 'base' Yukon Denali you can swap for a set of 22-inch chrome alloys for $2,995. Add it up, and an analyst at AutoTrends Consulting said that kind of margin "epitomizes the concept of obscene profitability." We say when it comes to Denali, GMC appears to stand for "Grabbing More Cash."
