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.

Buyers ditching expensive European sedans to buy expensive American trucks

The New York Times ended the automotive week with a story that adds numbers and context to a range of other stories, from the crossover craze to the increasing median price of a new car to ever more grandiose pickup trucks. The NYT piece reveals that the shift to larger vehicles isn't merely about the average U.S. buyer swapping the midsize sedan for a Ford Edge. Luxury buyers are migrating from plush sedans to plush SUVs and trucks that creep close to six-figure prices, and the Detroit Three are running Treasury presses because of it. From 2013 to 2017, the truck category — everything from pickups to minivans — climbed from 30 percent of the market to 41 percent. In January of this year, trucks claimed 66 percent of new vehicle sales. At the milk-and-honey end of profits, GMC alone accounted for 11.3 percent of all vehicle sales over $60,000, not just trucks. That puts the luxury truck maker behind Mercedes-Benz and Ford, The Blue Oval's feasting on Lariat, King Ranch and Raptor versions of the F-150, which make up more than half of that pickup's sales, putting it ahead of Chevrolet, Porsche and Lexus on the high-dollar sales list. The average transaction price of a GMC in Denali trim last year was $56,000; it's easy to see why, when one dealer told the NYT he just swapped a 2012 BMW 550i for a $71,000 GMC Sierra Denali. That truck starts at $52,900. The NYT started its story with a buyer who took home a Ford Raptor instead of an Audi A6, and optioned that $50,020 Ford Raptor close to $80,000. Over at Lincoln, the new $72,055 Navigator — the one so popular that Ford will increase production — crossed hands for an average sale price of $77,000 in January. And a Jeep dealer told the NYT that the two $93,000 Trackhawks he had on his lot "won't be here more than a few weeks." While trucks head up in sales volume and price, cars are headed so viciously in the opposite direction that "the Detroit Three and even some foreign manufacturers acknowledge they are now losing money on many of the cars they sell." So ... get ready for a lot more crossovers and trucks. Related Video: Find out what vehicle is right for you. Give our Car Finder tool a try.

GM files for Z71 Trail Boss trademark

Try as they might to keep their plans a secret, automakers have their hands tipped through a variety of methods – be they through loose lips, spy shots or patent and trademark applications. That's how we know, in this instance, that General Motors is working on (or at least considering) an off-road machine wearing the name Z71 Trail Boss – the name which our compatriots at AutoGuide.com tell us that GM has registered for use on light-duty trucks. Now if that alphanumeric designator sounds familiar, it should. GM has long used it to designate the off-road packages on many of its body-on-frame trucks from Chevy and GMC. These days you can order a Z71 package on the Chevy Colorado, Silverado, Tahoe and Suburban and on the GMC Canyon, Sierra and Yukon. The package typically includes components like a beefed-up suspension bits, high-capacity air cleaner and underbody protection plates. The Trail Boss designator would seem to suggest something further reaching than a suspension package, though. Just what it would entail we don't know; minds immediately start running toward Chevy or GMC going after the Ford F-150 Raptor, but we'll likely be looking at something closer to the Trailhawk packages Jeep offers on the likes of the Renegade and Cherokee.
