Chevy Bolt-based prototype may be a Buick EV for China

Late last spring, we got a look at a GM prototype that was clearly based on the Chevy Bolt EV, but with updated styling. It seemed like it could be a more crossover-styled Bolt, given the recently trademarked name of EUV. Now we get another look at the prototype, but the bodywork seems less suggestive of a Chevy, and more of a Buick. This vehicle definitely still appears to be based on the Bolt, rather than on another small GM platform. In the photos of it next to the current model, the size, wheelbase and profile are extremely similar. There are differences, though. The nose isn't as sloped or as rounded, and the rear window kicks up a little earlier. The biggest changes are in the front and rear fascias, and it's here that we see hints of Buick. There are prominent air inlets on each side of the front bumper that give the car a more aggressive look. The headlights still have a fairly rounded, organic look, but with little extensions like fangs underneath. The styled running-light section, rounded shape and the smoked lenses seem very Buick-like. The grille features a large badge that doesn't fit the shape of a bow-tie, and is more that of a round logo like Buick's. Around at the back, the full-width taillights stand out, and in the middle there is obviously a round badge, again like a Buick. The wide taillights would also be a natural evolution of Buick's current light design language that uses somewhat wide and thin lights. The rear bumper has been redesigned with new lower taillights. Now that we've established that this seems very much like a Buick, we don't think we'll see this particular version offered here with the badge. This is more likely a Buick version of the Bolt for the Chinese market, where the brand is associated with luxury and has been the spearhead for GM's electric and hybrid models. In fact, the Chevy Volt hybrid was sold there as the Buick Velite 5, which was part of a family of a electrified Velite models. This would probably also carry a Velite badge as well. While we might not see this specific Buick variant, we probably will see it offered as a Chevy in some form. With its more aggressive, crossover shape, it could be the rumored EUV model. Or it could be just a refresh of the current Bolt, since the model has been largely unchanged since its introduction for the 2017 model year. And extrapolating from this prototype, we can see how the headlights could be tweaked to tie into those air scoops as on the Suburban and Silverado.

Camaro SS, Hellcat Widebody, and an Airstream camper | Autoblog Podcast #545

On this week's Autoblog Podcast, Editor-in-Chief Greg Migliore is joined by Green Editor John Beltz Snyder and Senior Editor Alex Kierstein. We talk about a lot of American stuff, including the Chevy Camaro SS 1LE and the new Blazer, Dodge Challenger Hellcat Widebody, Ford's new train station and a diesel F-150 towing an Airstream trailer, as well as some Tesla pickup news. Somehow the Kia Stinger also made its way into this red, white and blue episode (because it's great, and it's our new long-termer). This week, we try something a little different in the "Spend My Money" segment. Autoblog Podcast #545 Your browser does not support the audio element.

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.
