Supercharged 2015 GMC Yukon Denali sounds evil, runs 0-60 in 4.5 seconds

Speeding along in a sports car is undoubtedly a ton of fun, but some owners need the ability to carry a lot of people and their stuff and don't want to sacrifice the ability to put the power down. The tuners over at Hennessey have that demographic covered with their growling, supercharged power kits for the GMC Yukon Denali. The upgrades come in three forms for the SUV's 6.2-liter V8: HPE550 with 557 horsepower, HPE600 with 605 hp and HPE650 with 665 hp. This video showcases the full-bore version, and this Denali can definitely hustle in a straight line. The power bump comes courtesy of a 2.9-liter supercharger, intercooler and high-flow cylinder heads to add over 200 horsepower compared to stock, and the final result is a bellowing SUV that rears up off he line to throw the driver back into the seat. The sprint to 60 miles per hour lasts just 4.5 seconds. Check out this hasty hauler in action in the video above.

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.

Mary Barra reportedly confirms GM's electric pickup truck plans

According to Motor Authority, CEO Mary Barra confirmed General Motors' intentions to build an electric pickup truck this week. Whether or not it would be an all-new vehicle is unknown. The news comes not even a week after Ford announced a $500 million investment in electric-vehicle startup Rivian. First, electric powertrains were integrated into cars. Then came the crossovers and the SUVs. Naturally, then, the next wave will be pickup trucks. Ford is set to produce an electric F-150, Rivian has the R1T, and now General Motors has reportedly confirmed its plans to introduce a competitor into the field. The article says the topic was brought up in a recent investor call as part of a brief overview of the automaker's electrification strategy. That's where the details end, however, as there is no indication of a timeline, what GM brand would carry the truck, or whether it would be an entirely new product or an adaptation of a current model. The latter seems most likely, which points to the Chevrolet Silverado or the GMC Sierra as possibilities. Chevrolet has been GM's electrification leader this decade with the Bolt and Volt, so an electric Silverado would align well with that messaging and branding. However, an electric pickup would likely be a pricier premium product, which could align it better with GMC.
