GM Ultium tech can scavenge heat from everywhere, even you

GM likes to give us tidbits about its Ultium platform from time to time, and today it’s telling us about the platformÂ’s ability to capture waste heat from the propulsion system. In addition to capturing from the propulsion system, it can also capture humidity from both inside and outside the vehicle and even from passengersÂ’ body heat. Yes, you, your family and/or your friends are a usable heat source as far as GM EVs are concerned. It then deploys the heat in an advantageous way. If at this point, youÂ’re screaming, "Heat pump!" youÂ’d be right. WeÂ’re talking about an elaborate heat pump system that GM is using for its Ultium-based vehicles. Every Ultium-based GM vehicle gets this system that is covered by 11 patents and four publications. The waste heat it collects is used in a number of ways, but its primary use is to heat the cabin quickly and efficiently. GM claims it can heat the cabin of its Ultium-based vehicles quicker than vehicles with traditional internal combustion engines. Plus, when put to use, GM claims that using the heat pump provides its EVs with up to 10% more range than theyÂ’d have without. Beyond heating the cabin, the heat pump is capable of putting waste heat to use by preheating the battery prior to charging so that you can charge quicker. The system can even cool the propulsion system in preparation for Watts to Freedom (WTF) launch control starts. GM says this was vital in helping the Hummer EV achieve its bonkers 0-60 mph time of about 3 seconds. “Having a ground-up EV architecture gives us the freedom to build in standard features like UltiumÂ’s energy recovery capabilities,” said Doug Parks, GM executive VP of global product development, purchasing and supply chain. “This helps us squeeze more efficiency, performance and overall customer benefit out of our EVs.” GM says itÂ’s been developing heat pump technology since the EV1 and its heat pump. This is the modern evolution of that technology, and GM says itÂ’s going to be implemented in every Ultium-based vehicle as a standard feature.

NHTSA investigating nearly 750,000 GM models over non-deploying airbags

Nearly 750,000 vehicles built by Chevrolet, GMC, and Cadillac are the subject of a National Highway Traffic Safety Administration (NHTSA) investigation due to non-deploying driver-side airbags. While the investigation is ongoing, the agency believes the issue is likely due to rust particles that form on the inflator's connection terminal interface. The list of nameplates included in the investigation includes Chevrolet's Silverado, Tahoe, and Suburban, GMC's Sierra, Yukon, and Yukon XL, plus Cadillac's Escalade, Escalade ESV, CT4, CT5, and XT4. All of the potentially affected vehicles are 2020 or 2021 models, according to a bulletin published on the NHTSA's website. Investigators launched the probe in April 2021 after 15 consumers reported airbag-related issues, including nine who said an airbag malfunction light appeared in the instrument cluster. More alarmingly, the NHTSA is aware of six accidents that caused significant damage to the car's front end yet didn't trigger the driver's airbag. It adds that there are no fatalities linked to the issue, but there are six crashes and eight injuries reportedly blamed on it. No evidence suggests this problem is related to the millions of potentially deadly Takata inflators recalled over the past few years. General Motors is aware of the defect. It sent a technical service bulletin (TSB) to its dealers in March 2021 to address the aforementioned warning light. The note explains the issue is due to "rust particles in the connection terminal interface of the driver's airbag inflator." The company hasn't issued a safety recall yet, however. Whether it will partially depends on the NHTSA's findings. It's currently looking into the scope and the severity of the problem, and it wants to understand its implications on driver safety. Investigators will decide whether General Motors needs to recall the 749,312 cars that are part of the probe when they close their investigation. General Motors has already spent a significant amount of money replacing defective airbag-related parts in its cars. In November 2020, it was ordered by the American government to recall nearly 6 million pickup trucks and SUVs equipped with potentially dangerous Takata airbag inflators. It repeatedly argued that testing proved the inflators were safe, and it petitioned the agency four times starting in 2016 to avoid a recall, which cost an estimated $1.2 billion (about a third of its net income in 2020).

2019 GMC Sierra Denali Drivers' Notes Review | Half measures

Associate Editor Reese Counts: This truck feels a full generation behind the competition. It's a half measure that feels more like a mid-cycle refresh than a whole new truck. There are a few high points: the 6.2-liter V8 is great (if thirsty) and the bed is wider than anything else in the class. The tailgate, too, is nifty, though some might write it off as a novelty. I also dig the tech, particularly the infotainment system and heads-up display. Ram might brag about its giant touchscreen, but I think I actually prefer the GMC's user interface. The rest can be summed up with a series of shoulder shrugs. The Sierra finally looks different than a Silverado, but I wouldn't call it handsome. The interior is spacious, but I'd knock the design and materials in a $45,000 truck, much less one approaching $70,000. It's not Toyota Tundra levels of terrible, it's just plain, cheap, and not nearly as space efficient as the Ram. It feels like GM's not even trying to move the needle with this truck. The more time I spend behind the wheel, the less I like it. Assistant Editor Zac Palmer: I got to spend a lot of seat time in this 2019 GMC Sierra Denali, and I came away generally unenthused by GM's most luxurious truck. We harp a lot about how expensive pickup trucks are these days, and this one's near $70,000 price tag is just the same. When you step inside a similarly-specced Ram, it feels like it's worth its price. When I step out of a Silverado and into a more expensive Sierra, I want to feel like it's money well spent. This Sierra Denali does not. Beyond the leather seats and a few small pieces of wood trim, it's hard, black plastic galore. What makes it all the more frustrating is that GM has most of the tech and features it needs (solid infotainment, 360-degree camera, wireless phone charging and the rear camera mirror is genuinely awesome). The presentation just comes off as dated from the start. It's a shame, because I have a strange affinity for how this truck looks from the curb. The sharp angles, brash styling and "tough truck" attitude is appealing to me. I like stomping on the gas and letting the 6.2-liter torque monster under the hood loose. But man do you pay the price for using that engine. Over a few hundred miles of driving I ended at a dismal 15 mpg reading on the trip computer — the saddest part of this was knowing these were mostly highway miles.
