Here are all the cars GM is axing as part of its restructuring

GM plans to kill off a couple of great and a few meh cars as part of its restructuring. Here's a rundown of all the cars being phased out of production. None of the vehicles GM axed were SUVs or crossovers. Instead, it was an action reminiscent of what Ford recently decided to do by discontinuing U.S. sales every Blue Oval sedan. GM just didn't explicitly say, "We're killing our cars," like Ford did — probably a smart move by GM. Keep scrolling down to see the full list of deceased GM models. Chevrolet Volt This one was the most surprising of all the cars GM decided to can, primarily because cars with plugs are supposed to be our future. However, maybe consumer demand just isn't quite there yet for a plug-in like the Volt. We came up with all sorts of ideas for what was to blame for the untimely demise of the Volt, so go check that out for a full breakdown of the situation. Cadillac CT6 Here's another car we'll be sad to see go. Cadillac's flagship sedan was such a joy to drive, and it served as the conduit to deliver GM's semi-autonomous Super Cruise system, which still hasn't been surpassed by any other company's technology in our books, even Tesla's Autopilot. That being said, GM does plan to produce the CT6 until March, with the last cars coming off the line set to be twin-turbo V8 V-Series models. If it's going to go, this seems like a pretty great way to make an exit. We'll be patiently awaiting the next flagship Cadillac once this one finally fades away. Chevrolet Impala The Impala is actually a pretty good car. It doesn't sell terribly, and we think it's a completely satisfactory car to drive. However, people would rather have a Traverse or Equinox these days, making the Impala one of the vehicles to find itself on this list. Chevrolet is keeping its smaller brother, the Malibu, but a big, full-size sedan just isn't what people are ordering up these days. It's unfortunate to see it go, but we won't be broken up over it. Chevrolet Cruze We wouldn't rank the Cruze at the top of the compact car class, but if you were looking for a small, cheap American car, it was either this or the Focus. The Cruze had the potential to be a true small performance car if Chevy had ever wanted to make it into one. But sadly, we're seeing it bow out before Chevy ever tried to slot a hot engine and suspension in there to make it competitive with other hot hatches. A Cruze SS would have made enthusiasts take notice.

How GM engineers are using diaper 'snow' to keep you warm

Testing how snow affects General Motors' vehicles isn't really a problem right now for the company's engineers, but in the dog days of summer the process isn't exactly easy. The only real option is for them to book time at the automaker's climatic wind tunnel. However, a flash of brilliance from an engineer allows snow to be simulated regardless of the temperature outside, and the discovery is all because of his daughter's wet diaper. The realization came to GM Thermal Systems engineer Nicholas Jahn while he was swimming with his daughter and noticed how her diaper ballooned in size in the water. He found out the substance that makes this possible is called sodium polyacrylate. When the material gets wet it grows and forms fluffy flakes that are a close imitation of snow. Best of all, the stuff can be prepared easily any time of the year, and it's reusable. The engineering team uses the material to test the effectiveness of the heating systems of GM's vehicles. They spread the sodium polyacrylate over the inlets at the base of the windshield to obstruct the airflow and then crank the heater. After some time, they can see how much is being sucked into the system and design more efficient systems in the future. See how the process works in the video above and read about the diaper discovery in GM's press release below. Diapers Change Chevy Cruze Winter Warm-up Time GM validation engineer uses diaper material "snow" to reduce frigid drives 2015-01-06 DETROIT – An item commonly found on an infant's changing table is helping General Motors' engineers simulate snow year round, ensuring heating systems in cars like the 2015 Chevrolet Cruze can quickly and efficiently warm its interior. Packed snow can prevent air from entering the inlet panel at the bottom of the windshield, obstructing the flow of air into the heating system and reducing the amount of air it can push out. This can lead to less efficient warming of the car's interior and windshield defrosting. "The last thing anyone wants to do when it's freezing cold out is scrape their windshield," said Nicholas Jahn, GM Vehicle Thermal Systems engineer. "The testing we perform on the Chevrolet Cruze with the diaper material allows us to maximize the car's heating capabilities." Ironically, Jahn stumbled upon his diaper-based testing method in the middle of summer. During a swim with his daughter, he noticed her diaper multiplied in size when it came into contact with water.

Leveling kit now available for Chevy Colorado, but not yet for GMC Canyon

In various bits of news this year concerning the Chevrolet Colorado and GMC Canyon pickups, we kept hearing about a front leveling kit. GM Authority found a few details in early order guides in January. In February, the kit came up in relation to the Canyon's AT4 Off-Road Performance Package, and again with AEV's upgraded Colorado Bison. After three months of waiting, GMA has more info. The kit eliminates the trucks' raked stance by raising the front by one inch, using an electro-coated upper spacer and a polyurethane lower spacer in order to maintain the proper suspension geometry. Installation is a bolt-on job with low-profile nuts, but the task will require a spring compressor. Fitted properly, the kit doesn't void GM's new vehicle warranty on the Colorado. Why do we only mention the Colorado? Because for some reason, the kit isn't available for the Canyon yet as a standalone component; the GMC stays raked without one of the aforementioned option packages. For Chevy, the leveling kit is compatible with any trim in four-wheel drive except the ZR2. It cannot be installed on two-wheel-drive trucks, nor any truck wearing wheels that are 20 inches or above. The kit is available now, ordered through any Chevy dealer for $150. There is a treat in store for GMC buyers, though, but it requires spending a lot more money. GM Authority discovered that the 2021 Yukon will offer the brand's first illuminated emblem. Priced at $475 as a dealer-installed option, a backlit glow will show off the GMC logo in the grille. The brand makes the logo in red and black, it's thought the red logo will get the nod, at least at first. Only the front logo earns the spotlight, not the one on the tailgate. GMA says the tchotchke will be available on all four trims when the new full-size crossover goes on sale in a few months.
