GM issues stop-sale for 3 SUVs over incorrect MPG rating

This week, GM sent a memo to Chevy, GMC, and Buick dealers to tell them to stop selling three SUVS. The 2016 Chevy Traverse, the GMC Acadia, and the Buick Enclave all have EPA window stickers that show higher fuel economy ratings than the vehicles actually have. Unlike other recent – and very public – fuel economy ratings problems from VW and Mitsubishi, it doesn't seem like GM did anything wrong with the testing for these vehicles, it just misprinted the labels. New labels are being printed and should arrive at dealerships this weekend and early next week. After that, the SUVs will be able to be sold and delivered again. The official fuel economy rating for the three SUVs are all the same. The correct numbers for the all-wheel drive versions are 17 miles per gallon combined, 15 city, and 22 highway. The stickers say the SUVs get 17/24/19. The front-wheel driver models were also incorrectly labeled, and the total number of affected vehicles is 59,823. In the memo, GM said the problem was caused by an "inadvertent error," Automotive News says. GM is working with the EPA to solve the issue. We have asked GM for a comment on the mistake and will update this post if we hear back. Related Gallery 2013 GMC Acadia View 16 Photos News Source: Automotive News – sub. req.

Opel did a great job on the 2018 Buick Regal

Ladies and gentlemen, the 2018 Buick Regal. The car you see is actually the Opel Insignia Grand Sport, but General Motors will bring it to the United States as the next-generation Regal virtually unchanged. The Insignia, revealed Wednesday by Opel, gets a sleek new design punched up with LED lights and sweeping proportions meant to conjure a fastback silhouette. It will debut in March at the Geneva Motor Show and launch next year in Europe. Expect the Regal to go on sale in the middle of 2017 in the US. The Opel-Buick relationship has been tight in the last decade, with the outgoing Regal earning strong praise for its German-tuned chassis and premium appearance. While Buick has been the recipient of much of Opel's work, the Insignia is now borrowing one of Buick's great names: Grand Sport. View 12 Photos Opel points to the Monza concept as the source of inspiration for the Insignia, though Buick will undoubtedly say the Avenir concept was the Regal's creative stimulus. Some think it looks like a Mazda. Mark Adams, vice president of GM Design Europe also oversees the automaker's global styling operations. "Its design combines flowing lines and subtle surfaces with crisp, precise lines to even exaggerate its dramatic proportions: it looks longer, lower, and wider than it actually is, and it definitely looks upscale," he said in statement. Expect similar thoughts for the Regal. Opel is also working on an Insignia wagon, which we've captured in spy photos before. We've also heard whispers that it will come to the US market with a Regal badge. Opel's announcement previews many of the details we'll see in the new Regal. Based on a new chassis, the Insignia is 386 pounds lighter than the previous car. The wheelbase is 3.62 inches longer and the track is .43 inches wider. Opel tapered the front and rear overhangs, so there's only a slight gain in overall length. The interior has more room, Opel says, and features a touchscreen with GM's IntelliLink system. The car will also have several drive modes, which tailor the chassis, throttle response, and shifting dynamics. Other technologies includes a head-up display, 360-degree camera, lane-keeping assist, adaptive cruise control, and cross-traffic alert. The Insignia will offer an eight-speed automatic transmission and all-wheel drive with torque-vectoring. We expect both to come to the US market. Meanwhile, another GM brand, Vauxhall, unveiled the Vauxhall Insignia for the British market.

How to hack a Buick Regal with CarKnow

If you own an Apple iPhone or Android device, perhaps you've been tempted to jailbreak or root it. This process gives you access to the the software's code, and can be used to make minor or drastic changes to its operating system. CarKnow, a company in Boston, is working applying a similar concept to the automobile.
Translogic recently took a look inside CarKnow to see just how it can tweak the computers inside a car and what sort of things can be done. As our transportation tech sister site explains, CarKnow basically created a digital duplicate of their Buick Regal in the cloud, while harvesting data generated to create custom apps and infiltrate the deepest function of their test car.
And before you freak out about people maliciously taking over your car, CarKnow's founder, Josh Siegel, stresses that it isn't quite so easy as driving up alongside someone. Take a look at the full video below to see just what it's like to jailbreak a car.
