GM's MPG overstatement could affect 2 million vehicles

Late last week, GM admitted that three of its large SUVs fuel economy window stickers did not match their actual efficiency ratings, and so the vehicles couldn't be sold. The stickers on the 2016 Chevy Traverse, GMC Acadia, and Buick Enclave said their ratings were one to two miles per gallon better than they should have been. Officially, the number of affected vehicles sits at about 60,000. But Consumer Reports makes a good point: what's up with all of the previous model year SUVs that are basically the same vehicle? To wit: the 2016 model year vehicles are not substantially different than the 2015 or the 2014, or even going all the way back to 2007. On the EPA's fuel economy website, all of these older models will "have better stated fuel economy numbers than the new vehicles in GM's dealerships," Consumer Reports noted. CR's best point, and the one that makes the 60,000 number potentially grow to 2 million if all of the vehicles built on this platform are affected, is that "[i]t seems unlikely that the company would change the powertrain on these carryover models so late in their model cycles in a way that would cause a dramatic, negative impact on fuel economy." GM says that earlier model year SUVs are not affected and the EPA did not respond to CR's question about the potential for more discrepancies. We've seen automakers reverse course before, so if GM has to come out with a mea culpa soon, don't be surprised. GM is rushing corrected stickers to dealers so that the SUVs can be sold again, but a fix for the already-sold vehicles could be trickier to solve.

GM seeks national mandate for zero-emissions cars

DETROIT — General Motors says it will ask the federal government for one national gas mileage standard, including a requirement that a percentage of auto companies' sales be zero-emissions vehicles. Mark Reuss, GM's executive vice president of product development, said the company will propose that a certain percentage of nationwide sales be made up of vehicles that run on electricity or hydrogen fuel cells. GM says a nationwide program modeled on such a requirement in California could result in 7 million electric vehicles, or EVs, on U.S. roads by 2030. California wants 15.4 percent of vehicle sales by 2025 to be EVs or other zero emission vehicles. Nine other states, including Maryland, Massachusetts, New Jersey and New York, have adopted those requirements. In January, California Governor Jerry Brown set a target of 5 million zero-emission vehicles in California by 2030. The Trump administration criticizes California's ZEV mandate, saying it requires automakers to spend tens of billions of dollars developing vehicles that most consumers do not want, only to sell them at a loss. Reuss told reporters that governments and industries in Asia and Europe "are working together to enact policies now to hasten the shift to an all-electric future. It's very simple: America has the opportunity to lead in the technologies of the future." A national mandate also would create jobs and reduce fuel consumption, CO2 emissions and "make EVs more affordable," Reuss added. GM, the nation's largest automaker, will spell out the request Friday in written comments on a Trump administration proposal to roll back Obama-era fuel economy and emissions standards, freezing them at 2020 levels instead of gradually making them tougher. Under a regulation finalized by the Environmental Protection Agency at the end of the Obama administration, the fleet of new automobiles would have to get 36 miles per gallon by 2025, 10 mpg higher than the current requirement. But the Trump administration's preferred plan is to freeze the standards starting in 2021. Administration officials say waiving the tougher fuel efficiency requirements would make vehicles more affordable, which would get safer cars into consumer hands more quickly. GM on Thursday said it doesn't support the freeze, but wants flexibility to deal with consumers' shift from cars to less-efficient SUVs and trucks.

Buick Envision Plus is a seven-seater tweener developed for China

Buick has filled the gap separating the Envision and the Enclave with a new crossover named Envision Plus. Launched at the Shanghai auto show, the three-row people-mover is scheduled to go on sale in China later in 2021. The plus-sized Envision stretches 190.7 inches long, 74.1 inches wide, and 66.7 inches tall, figures that make it around eight inches longer and two inches taller than the regular Envision. It's also a full 14 inches shorter, four inches narrower, and three inches lower than the Enclave, which is the biggest crossover in the Buick range. Designers didn't settle for stretching the Envision's wheelbase. They gave the Plus a more upright front end characterized by a taller grille, a flatter and longer roofline, and a redesigned rear end accented by a strip of bright trim that connects the lights. Only photos of the upscale Avenir trim (shown above) have been published so far. Images of the cabin are not available yet. We expect the Plus offers an interior close to the standard Envision's — from the driver's point of view, at least. The biggest difference is that the longer Envision lives up to its name by letting motorists take more gear or kids along for the ride thanks to a more spacious trunk and third-row seats. Power for the Envision Plus comes from a turbocharged, 2.0-liter EcoTec four-cylinder engine fitted with 48-volt mild-hybrid technology. Bolted to a nine-speed automatic transmission, the turbo-four is the same basic engine found in the American-spec Envision, where it develops 228 horsepower and 258 pound-feet of torque, but figures for the Plus weren't released. Front- and all-wheel-drive models will presumably be available. Buick will release pricing information closer to the model's on-sale date. As of writing, the Envision Plus has only been announced for China, where it will be built, but unverified reports claim it will arrive in American showrooms before the end of 2021. We've reached out to the company, and we'll update this story if we learn more. 2021 Buick Verano Pro GS View 5 Photos What else did Buick show in Shanghai? Buick no longer sells sedans in America, but it remains present in that segment on the Chinese market. In addition to the Envision Plus, it unveiled a model named Verano Pro developed specifically for China, built locally, and aimed at relatively young buyers. At launch, motorists will be asked to choose between the regular sedan and a sportier-looking variant that wears the storied GS emblem.
