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.

GM will compensate SUV owners for fuel-economy error [UPDATE]

General Motors will offer debit cards to owners of some of its crossover SUVs after it was discovered that GM overstated the vehicles' fuel economy on window stickers, Automotive News says. GM will offer reimbursements to about 135,000 customers that are worth between $450 and $1,500 each. Some owners will also have the option of being provided with an extended warranty free of charge instead of the debit card. GM overstated fuel economy on about 170,000 vehicles by one to two miles per gallon because of what it has said was an inadvertent error stemming from not factoring the impact of emissions-related hardware into the EPA window-sticker figures. As a result, GM put a temporary stop-sale on the Chevy Traverse, GMC Acadia, and Buick Enclave before switching out the window stickers on about 60,000 vehicles. Automotive News says letters and debit cards will be sent out next week, and Reuters is estimating that the reimbursement program will cost GM about $100 million. With automakers ranging from Hyundai/Kia to Ford to, more recently, Volkswagen and Mitsubishi being ensnared by emissions or fuel-economy-rating issues, GM is working quickly to address the problem. For those curious, the reimbursement totals, factoring in current gas prices, the SUVs' combined fuel economy, and typical driving of about 12,000 miles a year, will provide between three and 12 months worth of free gas for those drivers (the models get either 17 or 18 miles per gallon combined, depending on front- or four-wheel-drive configuration). While about 135,000 customers will be reimbursed, Automotive News says the fleet buyers of about 35,000 crossovers haven't been addressed yet. UPDATE: GM spokesman James Cain, in an e-mail to Autoblog on Sunday, confirmed that the company will reimburse about 135,000 customers. Purchase customers will be given the option of a pre-paid debit card or a 48-month/60,000-mile protection plan, while lease customers will be offered the pre-paid debit cards. Most of the cards will have a value of between $450 and $900 on them. "We want all of our customers to have a great ownership experience, so we designed this reimbursement program to provide full and fair compensation in a simple, flexible, and timely manner," he wrote.

GMC teases Hummer EV's removable roof panels

Today was supposed to be the day that GM took the wraps off its GMC Hummer EV. We were told as much during the Super Bowl commercial, but GM revised it to an undecided future date, citing the coronavirus as the reason. Instead of the big reveal, we have a teaser.  The Hummer EV is going to feature removable roof panels, and now we get a better look at them. There are four roof panels and a front T-bar that come out of the truck. You can see what that looks like in the video at the top of this post. Comparisons to Jeep are obvious as the open-air experience is likely similar to the Gladiator and Wrangler with their hardtop roof panels removed. That zero-limits slogan makes a bit of sense from this respect. With the sheer number of roof panels, we suspect a single person will be able to remove them alone. In addition to the video of the roof, we get a small peek at the massive digital screens the Hummer will be sporting. Check them out at the bottom of the photo below. They appear to be two large slabs, separate from each other. Other details are scarce on the ground. We’re not sure when the Hummer will make its grand entrance at this point, but are still excited to see the 1,000-horsepower truck hit the road. GMC is still advertising the 0-60 mph time of just 3 seconds, too. The latest tidbit of news suggests that further teasers might be coming, so we could be in for a rather drawn out reveal process. Our senior green editor John Snyder got to see the GMC Hummer in person earlier this year at GMÂ’s EV Day and described it like this: “ItÂ’s a big, off-road-ready pickup complete with giant all-terrain rubber and tow hooks. It features removable roof panels for access to the open sky, which appears to be depicted in the teaser above. It features sail panels behind the C-pillars, similar to those on the Chevy Avalanche and Honda Ridgeline. Its bed was concealed with a tonneau cover, but it sported GMCÂ’s MultiPro tailgate that we first saw on the Sierra Denali. Interior photos showed a spacious interior with blocky shapes, squared hourglass vents that mirror the look of the taillights and a lunar theme that incorporates the topography of the Sea of Tranquility into things like the floor mats and speaker covers. It also has a large infotainment screen as well as a digital instrument panel.” Related video:
