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 cutting Chevy Sonic, Buick Verano production by more than 20%

General Motors' Orion Assembly plant in Michigan is seeing even more production cuts this year to further reduce inventories of the Chevrolet Sonic and Buick Verano. These latest adjustments mean layoffs for about 100 workers in phases starting in July. "GM Orion Assembly will adjust plant production capacity to better align with market demand," the company said in a statement announcing the change. Through May, sales of the Sonic are down 28.5 percent to 29,082 vehicles, and the Verano is off 15.6 percent, with 15,279 sold this year. According to unnamed plant insiders speaking to Automotive News, the assembly rate is slowing at Orion Assembly from the current 33 cars an hour down to 26 an hour, a 21-percent reduction. GM is also reportedly going to keep the plant idle for three weeks during the normal summer shutdown, rather than the usual two. Earlier in the year, the factory was idled for two weeks due to excess supply of the Sonic and Verano. In March, it was closed again for several days for the same reason. The Orion Assembly plant is the future home to the line for the Chevy Bolt EV. GM Statement: GM Orion Assembly will adjust plant production capacity to better align with market demand. A phased layoff of approximately 100 employees will begin in July 2015 and conclude by year-end.

GM won't really kill off the Chevy Volt and Cadillac CT6, will it?

General Motors is apparently considering killing off six slow-selling models by 2020, according to Reuters. But is that really likely? The news is mentioned in a story where UAW president Dennis Williams notes that slumping US car sales could threaten jobs at low-volume factories. Still, we're skeptical that GM is really serious about killing those cars. Reuters specifically calls out the Buick LaCrosse, Cadillac CT6, Cadillac XTS, Chevrolet Impala, Chevrolet Sonic, and the Chevrolet Volt. Most of these have been redesigned or refreshed within the past few model years. Four - the LaCrosse, Impala, CT6, and Volt - are built in the Hamtramck factory in Detroit. That plant has made only 35,000 cars this year - down 32 percent from 2016. A typical GM plant builds 200,000-300,000 vehicles a year. Of all the cars Williams listed, killing the XTS, Impala, and Sonic make the most sense. They're older and don't sell particularly well. On the other hand, axing the other three seems like an odd move. It would leave Buick and Cadillac without flagship sedans, at least until the rumored Cadillac CT8 arrives. The CT6 was a big investment for GM and backing out after just a few years would be a huge loss. It also uses GM's latest and best materials and technology, making us even more skeptical. The Volt is a hugely important car for Chevrolet, and supplementing it with a crossover makes more sense than replacing it with one. Offering one model with a range of powertrain variants like the Hyundai Ioniq and Toyota Prius might be another route GM could take. All six of these vehicles are sedans, Yes, crossover sales are booming, but there's still a huge market for cars. Backing away from these would be essentially giving up sales to competitors from around the globe. The UAW might simply be publicly pushing GM to move crossover production to Hamtramck to avoid closing the plant and laying off workers. Sales of passenger cars are down across both GM and the industry. Consolidating production in other plants and closing Hamtramck rather than having a single facility focus on sedans might make more sense from a business perspective. GM is also trying to reduce its unsold inventory, meaning current production may be slowed or halted while current cars move into customer hands. There's a lot of politics that goes into building a car. GM wants to do what makes the most sense from a business perspective, while the UAW doesn't workers to lose their jobs when a factory closes.
