The Chevrolet Bolt is headed to China as a Buick SUV

When spy photos of what appeared to be Chevrolet Bolt EV with some minor front- and rear-end updates circulated last week, Autoblog surmised that GM was working on some sort of Bolt-based vehicle — potentially a crossover — to be sold in China as a Buick. We may just have corroboration for that theory. On Thursday, Motor1.com spotted a story published earlier this week on the Chinese site Auto Home which claims that GM has applied to sell an all-electric SUV under the Velite 7 nameplate in China.  There's little differentiating the Velite 7's exterior from the Bolt EV's, apart from bumpers, badges, and a little extra ground clearance. Up front, the bowtie is replaced by a round Buick badge, and the bumper picks up an almost Prius-like appearance thanks to contrasting vertical elements and a thin grille bleeding into the head lights to give it a full-width appearance. Chevy Bolt-based prototype View 16 Photos If the Chinese report is accurate, there is one significant difference under the skin. Per the application, the Buick crossover variant is to be powered by a 174-horsepower electric powertrain. That's down 26 horsepower from the Bolt EV's powertrain, and we can't help but think that a lifted Buick variant might just need every pony it can get.  The needs of the Chinese market are unique, and we're certain GM knows what it's doing if these figures are accurate. We have no reason to believe Buick plans to sell the Velite 7 EV here in the States, though we expect an updated Chevy Bolt eventually, and we wouldn't be surprised if Buick brings something along shortly to fill the void left by the departure of the Regal sedan and its variants.  Related Video:

GM exploring ways to raise half-ton Duramax diesel tow rating

Lots of truck owners cheered when GM announced fuel economy numbers for the 2020 Chevrolet Silverado with the 3.0-liter Duramax diesel inline-six. Even after Ram let loose its EPA mileage ratings for the 2020 Ram 1500 EcoDiesel, the Chevy oil-burner still took the trophy. The victory was years in the making, GM engineers spending an entire four-year development cycle refining the LM2 Duramax to increase mileage. The tradeoff, as well all know by now, is towing; the Duramax in half-ton duty pulls a maximum 9,300 pounds in the Silverado. Rivals across town can do more, the Ford F-150 PowerStroke rated at 11,500, the Ram 1500 EcoDiesel game to pull 12,560. GM engineer John Barta told Muscle Cars & Trucks that more hauling chops could be on the way, explaining, "We’re actually looking at upgrading some of the materials around (the engine bay) to see if we can maybe raise our tow rating." Engine bay materials are at issue due to thermal complexities underhood. John Barta, GM's assistant chief engineer of diesel engine controls, said the Duramax's inline-six configuration allowed engineers to get emissions hardware like the combined selective catalytic reduction, diesel oxidation catalysts, and diesel particulate filter unit closer to the engine, where it heats up quicker, getting emissions down quicker. But that filter puts another heat source in those confines, enforcing a cap on the tow rating to keep the engine and other systems from overheating. "If you look under the hood," he said, "youÂ’ll see a significant amount of silver ‘moon tapeÂ’ around to make sure things arenÂ’t getting overheatedÂ… if we were to go up in higher towing, which we can, we start impacting the possibility of deteriorating some of the components.” There isn't much space for more grille, so swapping for a better grade of "moon tape" or a different kind of material could reduce engine bay heat, extracting a higher tow rating in the process.  It's important to note a point Barta's been making for months about the Duramax figures, though. "Even though itÂ’s nice to brag about big numbers, in reality, light duty customers are not towing that large with their trucks," and, "We do know that (95 percent) of our light duty customers donÂ’t tow over 9,000 pounds." On our First Drive of the 2020 Silverado diesel we called out the tow rating, but emphasized that the Chevy and GMC have more important challenges to overcome.

GM recalling over 40,000 Chevy, Pontiac and Saturn models over fuel pump woes

The National Highway Traffic Safety Administration has issued a recall for a number of General Motors cars and crossovers bought or currently registered in the hot-climate states of Arkansas, Arizona, California, Nevada, Oklahoma and Texas. As many as 40,859 units consisting of the 2007 Chevrolet Equinox, Pontiac Torrent and Saturn Ion and the 2007-2009 Chevrolet Cobalt (shown) and its Pontiac G5 twin are being recalled for potential fuel leaks.
This recall is being issued due to potentially faulty fuel pump components that can crack and cause gasoline to leak from the return or supply ports and possibly cause a fire. NHTSA has not indicated how many fuel leaks or vehicle fires have been reported. As a fix, GM will replace the fuel pump modules on all affected vehicles free of charge. Since Pontiac and Saturn have been shuttered, owners will be able to go to another GM-brand dealership to have their vehicles repaired.
While the list of affected cars and crossovers varies by state and model year, if you own any of these models and live in Arizona, California, Florida, Nevada, Oklahoma or Texas, be sure to check the official notice below for more details.
