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.

GM opens official investigation into C8 Corvette transmission leaks

In March 2020, a month after Chevrolet began customer deliveries of the 2020 C8 Corvette, a GM dealer technician created a Reddit thread about a leaking gearbox in a Corvette with 32 miles. That car hadn't even been sold yet. Since then, as a search of "C8 Corvette transmission leak" shows, it's been tales of woe for some owners. Something in the Tremec TR-9080 transaxle in the back of the mid-engined Corvette doesn't work as it should, the fault able to cause codes that the transmission needs service, or that the driver needs to shift to park. In some cases, the battery would die because of follow-on issues after the initial transmission code, that code preventing the car from powering down. As Autoevolution reports, GM filed paperwork with the National Highway Traffic Safety Administration in August to look into what's going on. Between forum threads and GM's investigation document, there are several issues mentioned. The most common appears to be the dual-clutch transmission leaking fluid due to gasket failures like the one suffered by one owner at 858 miles, and another for an owner currently enduring a second leaking transmission. The Midengined Corvette Forum reported that Chevy engineers redesigned the TR-9080 pan, fitting Corvettes with the new unit at some point in the 2021 model year. The original pan was stamped steel unit affixed to the engine with two studs and 13 bolts, plus "reinforcement plates." The updated pan is said to be a cast aluminum unit affixed with two studs and 17 bolts, omits the reinforcement plates, and gets a new machined new groove around its edge to seat the gasket seal. The GM paperwork now at the NHTSA mentions a P1789 code, and says one reason for it could be "debris on the park position sensor magnet causing an incorrect position reading to the TCM." This might be caused by another issue mentioned in forums, which is clogged transmission filters. GM gives instructions for returning transmission filters to the company, and a poster on one forum said the Corvette tech at the dealer where he bought his Corvette told him the automaker "requires every used transmission filter to be returned to GM."  Whatever's going on, the problems haven't stopped, and they go beyond the P1789 code. Over the weekend, a 2022 Corvette owner posted on Corvette Forums that he got a check engine light on his car after just 850 miles.

Chevy donates first 2015 COPO Camaro for wounded vets

Want to get your hands on a new COPO Camaro? Only 69 will be made this year before it's phased out ahead of the next Camaro's arrival. And the very first one will be auctioned off this weekend in Palm Beach. That's where Barrett-Jackson will be selling the hand-built drag-racer with the serial number 2015COPO001. The vehicle is being donated by Chevy, with 100 percent of the proceeds benefiting the Achilles Freedom Team of Wounded Veterans, a charitable organization that helps disabled athletes, especially veterans of the armed services. Introduced last fall at SEMA, the 2015 COPO Camaro is built specifically for drag racing with a 350-cubic-inch LSX racing engine with a 2.9-liter Whipple supercharger. It's got 555 horsepower, a three-speed automatic transmission (it's a drag machine, not a circuit racer after all), all the requisite safety equipment, special suspension setup, unique livery and a quarter-mile time in the mid-eights. Look for this unique example to cross the auction block at around 5 PM on Friday, April 18, when we hope it will raise a princely sum for a good cause. 2015 COPO Camaro No. 1 Sale to Benefit Disabled Veterans Top bid from Barrett-Jackson goes to Achilles Freedom Team of Wounded Veterans DETROIT – Chevrolet is selling the first 2015 COPO Camaro race car to raise money for Achilles Freedom Team of Wounded Veterans, which helps wounded veterans participate in marathons and share their success within a supportive community including their families. The hand-built car carries serial number 2015COPO001. It will be sold on Saturday, April 18, at the Barrett-Jackson Palm Beach auction, with 100 percent of the winning bid going to Achilles Freedom Team of Wounded Veterans, a non-profit organization that helps disabled athletes, including veterans, gain access to races, equipment, and training dedicated to improve their physical abilities. "This sale gives the highest bidder the opportunity to buy the first of only 69 factory-assembled 2015 COPO Camaro race cars, the final year of the fifth-generation Camaro," said Jim Campbell, U.S. vice president of Performance Vehicles and Motorsports. "Chevrolet is excited to offer this milestone Camaro to help a very worthy organization." Chevrolet introduced 2015 COPO Camaro No. 001 last fall at the SEMA Show in Las Vegas, and it has been featured in Chevrolet Performance advertising and other marketing initiatives.
