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.

Meet the Greenest and Meanest vehicles of 2016

If you've been keeping track, you won't be surprised with the number one entry in this year's list of greenest cars from the American Council for an Energy-Efficient Economy (ACEEE). In fact, the top three spots on the 2016 list are all the same as they were in 2015. After that, things get interesting. For one thing, this is the first Greenest list that doesn't have any purely internal combustion engine powertrain on it. Hybrids, yes, but if you want to be one of the top 12 greenest cars this year, you'd better have some sort of electric angle. ACEEE says that the conventional, gas-powered Smart Fortwo and Chevrolet Spark just missed the cut. In a statement, ACEEE lead vehicle analyst Shruti Vaidyanathan said, "The 2016 scores are in, and plug-in electric vehicles are outpacing all other vehicle offerings in terms of environmental friendliness." Like last year, one of the noticeable vehicles missing from the green list is the Tesla Model S. One reason? ACEEE takes curb weight into account (lighter is better), and the Model S is a heavy beast. The ACEEE doesn't just look at the clean side of the ledger. It also puts out a "meanest" list. These are the vehicles that pollute the most, not only from their tailpipes, but also any pollution created during the entire manufacturing process, from mining the raw materials to the energy used to produce the vehicle at the factory. The entire list, from greenest to meanest, is done using a "cradle to grave" analysis.

GM reintroduces Tripower name in the worst way possible

The story of General Motors' use of the Tripower moniker begins way back in 1957, when Semon E. "Bunkie" Knudsen, then General Manager of GM's Pontiac division, directed his engineers to inject more performance into his brand's line of V8-powered automobiles. Fuel injection was an option, but hot rodders flocked instead to Tri-Power (marketed way back when with a hyphen), which grafted a trio of two-barrel Rochester carburetors onto a single intake manifold. A legend was born. And that legend was born of performance. At idle and when full power wasn't required, Pontiac's Tri-Power system used just the middle carburetor, which helped make the setup easier to tune. Depending on the year and model, either a vacuum system or a mechanical linkage opened up the two outer carbs, thereby switching from two barrels to six, and allowing the engine to take in more fuel and air. And it was an easy marketing win – six barrels is better than four barrels, right? Because performance! So, when news filtered in that GM has resurrected the Tripower name, those of us who grew up attending classic car shows and wrenching on old Pontiacs did a double-take. And then we all collectively sighed. Turns out that today's Tripower refers to a trio of fuel-saving measures that include cylinder deactivation, active thermal management, and intake valve lift control, according to Automotive News. And, at least for now, it applies to GM's line of fullsize trucks powered by a 2.7-liter turbocharged four-cylinder engine. We're all for saving fuel whenever possible. And we have zero say in how any automaker chooses to market its products and technologies. But, we'll offer our two cents anyway: Relaunching a storied name from the past is fine. Relaunching a storied name from the past while completely overlooking the reasons the name got famous in the first place is only going to irritate the people who remember the name in the first place. Couldn't they just call this new technology package something else?
