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.

Callaway debuts its new C7 Stingray at National Corvette Museum

Callaway showed off its first tuned version of the 2014 Corvette Stingray at the National Corvette Museum last week, giving the rampant enthusiasts of America's sports car a look at the roughly 620-horsepower, supercharged rocket.
Unlike the Corvette SC610 we showed you back in January, this Stingray packs a fair bit more oomph. Horsepower is only up ten ponies, but torque has jumped from 556 pound-feet to "at least" 600 pound-feet. Neither horsepower nor torque is official quite yet, although Callaway is expecting to know just what its creation can do once testing and validation is completed later this month.
The 6.2-liter, supercharged V8 now boasts a new, three-element intercooler, which Callaway claims only allowed the inlet air temperature to increase by ten degrees Fahrenheit during dyno runs. Previous designs saw a 35-degree-Fahrenheit jump. The exhaust system has also been fettled with, and now is even less restrictive.

Detroit Three's lucrative pickup war intensifies as Ram makes big gains

DETROIT — The battle for profits from sales of large pickup trucks is intensifying among the Detroit Three automakers as sales of small cars in the United States shrivel. For decades Ford has had the single best-selling truck brand in its F-Series trucks. General Motors' Chevrolet brand was a solid No. 2, and Fiat Chrysler Automobiles' Ram was a distant third. Now, that hierarchy may be in flux. Sales figures for December and the fourth quarter released on Thursday show Ram tied with GM's Chevy for the No. 2 spot, as sales of the redesigned Ram pickup surged, fueled in part by demand for an optional 12-inch (30.48 cm) dashboard screen. Chevy not long ago held second place to Ford by a wide margin. GM executives said on Thursday they are bullish on their new GMC and Chevy trucks for 2019.Related: How the Detroit Three's pickups compare on paper 2019 Ram 1500 Laramie review 2019 Chevy Silverado 2.7L four-cylinder review 2019 Ford F-150 2.7L EcoBoost review "There's no doubt this segment (pickup trucks) is one of the epicenters of the auto wars," said Sandor Piszar, director of marketing for Chevrolet at GM. "It's been that way forever, and we wouldn't have it any other way." On Wall Street, investors give electric car leader Tesla a higher valuation than any of the Detroit automakers. But in the nation's heartland, big pickups remain far more popular and profitable than any electric car — and most other consumer vehicles of any kind. Large pickups generate at least $17,000 a vehicle in pretax profit for GM, the company has indicated in disclosures to investors. By contrast, many Detroit Three sedans are so unprofitable, their manufacturers have decided not to build them anymore. 'Hotly contested' Sustaining sales and pricing in the large-pickup segment will be critical in a year when most forecasters expect overall U.S. car and light truck sales to fall. Ford's U.S. sales chief, Mark LaNeve, on Thursday called the F Series "the backbone of our franchise" during a conference call, and added the "segment will continue to be strong, but hotly contested" in 2019. Automakers are banking on pickup truck sales to stay strong even if U.S. interest rates continue to rise. Rising interest rates translate into higher monthly car payments and are expected to deter some buyers in 2019. GM has said 27 percent of Chevrolet and GMC trucks — which can haul trailers by day and substitute for a luxury sedan by night — sell for more than $55,000.
