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.

Automakers' sound systems: Crank it, don't yank it

Years ago, one of the first things most music lovers did after buying a new vehicle was drive to an aftermarket stereo shop to get the crappy stock components swapped for better gear. And you'd typically get not only better sound but also more bang (and boom) for your buck. But in the past decade or so, the overall quality of OEM audio has dramatically increased, while car electronics became more complex, removing the incentive for most new vehicle owners — and all but the most hardcore DIYer — to start from scratch. In 2010, I did a comparison of the average costs for OEM electronics vs. similar offerings from the aftermarket, and back then automakers' stock premium systems were by far the best bargain — and are probably an even better value now. The premium 14-speaker, 1,200-watt JBL system in the all-new 2019 Toyota Avalon is a prime example of this trend. It's standard on the top two Limited and Touring trims and is available as a $680 audio upgrade on the XLE and XSE. I doubt you can even buy 14 speakers and 1,200 watts of amplification from the aftermarket for 700 bucks, much less have it all installed. And because the system is bundled with Toyota's Entune infotainment system, Apple CarPlay and a surround-view camera, removing the head unit means you would likely lose these features. Another advantage of OEMs and their audio partners is they can design the car around the audio system. In the past, automakers would typically place speakers where convenient for packaging, not for optimal sound reproduction, and audio engineers were forced to compromise. But as with the Avalon's premium JBL audio system, this is starting to change. At a recent behind-the-scenes peek for media into the process of developing the system, Toyota and Harman engineers delved into the minutia of sealing the inner panel of the front doors to create an enclosure for 6x8-inch woofers, making space in the pillars for JBL horn tweeters and extensively measuring the acoustic properties of the interior to tune the sound to the space. I'm met some creative and skilled car stereo installers, but none with a degree in psychoacoustics. The system is also the first to feature Quantum Logic Surround that creates a multi-channel listening experience from two-channel sources. And it includes Harman's Clari-Fi processing that "rebuilds key details lost" in compressed audio formats used by streaming music services and MP3s.

Junkyard Gem: 1993 Buick Roadmaster Sedan

In 1931, GM's Buick Division introduced an eight-cylinder engine in its stolid rear-wheel-drive sedan models, and Americans could buy big, comfortable Buick four-doors with straight-eights and — starting in the 1954 model year — V8s driving the rear wheels for more than a half-century after that. Then, the last rear-wheel-drive LeSabre left the assembly line in 1985, and it seemed that an era had ended forever. But wait! For the 1992 model year, Buick revived the Roadmaster name and applied it to an old-timey giant sedan with a V8 engine sending power to the proper wheels. Production of the Roadmaster sedan continued through 1996, and I've found one of those throwback Buicks in a Denver self-service car graveyard. Yes, in an America full of front-wheel-drive cars contaminated by European or — even worse — Japanese influences, The General brought back the spirit of the 1931 Buick sedan. Sure, it was really a near-identical twin to the "whale-body" Chevy Caprice, complete with Chevrolet small-block V8 engine, but that didn't matter. This was the kind of Buick that our prosperous great-grandparents bought in 1932 and 1948 and 1957. And the appeal of the great big eight-cylinder Buick sedan wasn't just limited to the United States. When the film adaptation of the great Marguerite Duras novel, L'Amant, was made, only a 1932 Buick 90 sedan would have made sense for the wheels of the wealthy Saigon heir. A big reason Buick is such an important brand in China right now is the legacy left by the memorable Buick machinery that owned the roads of 1930s China. These days, most of the 1992-1996 Roadmasters you'll see will be the station wagons, but we mustn't forget the sedans. Looking at the interior of this car is like a flashback to the 1960s, when stately Buick sedans had squishy seats you'd just disappear into when you climbed in. Cool-sounding names for ordinary features had gone out of style decades earlier, but not for the Roadmaster! Dynaride was a rear suspension that used air shocks and a compressor to keep the ride height level regardless of load. The last model year for a genuine Buick V8 engine was 1980, though you could make the case that the Rover V8 (made until 2006) was really a Buick all along. The engine in this car is pure Chevrolet: a 5.7-liter small-block V8 rated at 180 horsepower. Buick was a big Olympics sponsor at this time, while Oldsmobile handled golf. Still, the Buick-buying demographic of 1993 tended to approve of golf.
