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.

GM re-recalls 11k SUVs

General Motors is recalling a bunch of previously recalled SUVs because, well, they still aren't quite fixed. The latest repairs are necessary on 10,974 SUVs in North America, including 9,932 in only the US. Affected models include the 2006-2007 Buick Rainier, Chevrolet Trailblazer, and GMC Envoy; plus the 2006 Trailblazer EXT and Envoy XL. While not listed by NHTSA, a statement by GM to Autoblog says the 2006-2007 Saab 9-7X and Isuzu Ascender are also affected. In these SUVs, it's possible that liquid could get into the driver's door master power window switch module and cause a short circuit. This could potentially lead to a fire, and owners are urged to park the vehicles outside until repaired. GM has been trying to fix this issue for years. It started as an investigation into fires, and that led to a recall for about 250,000 vehicles in cold-weather states. A nationwide campaign came in 2013 for 193,000 of them in the US. Last year, the automaker decided to replace the whole module as a repair. However in a recent investigation of these recalls, GM discovered that this latest group of SUVs never received the new part. According to documents submitted to NHTSA (as a PDF), "Some dealers incorrectly used the labor code associated with module replacement when, instead of replacing the module, they only added a protective coating to the module." To fix things this time, the models finally get the correct component.

Certain 2006 Chevrolet TrailBlazer EXT and GMC Envoy XL, and 2006-2007 TrailBlazer, Envoy, Buick Rainier, Saab 9-7X and Isuzu Ascender vehicles may continue to have a condition in which the printed circuit board inside the driver's door may corrode and short if exposed to certain fluids such as melted snow containing road salt. GM is aware of four fires but no crashes, injuries or fatalities associated with the expanded recall. The total number of vehicles being recalled, including Canada, Mexico and exports is 10.974. Customers are urged to park these vehicles outside until repairs have been made. GM reported this recall to the NHTSA on September 23.

2021 GMC Canyon gets AT4 trim and a 'more upmarket' Denali

The AT4 train continues at GMC, with the 2021 Canyon AT4 climbing to altitude in Vail, Colorado, to announce its arrival. The off-road package, teased during the Sierra HD launch last year and already rolled out on the Sierra and Acadia, replaces the Canyon All Terrain trim. The rectangular grille goes away, the new rig picking up a larger, Sierra-like grille with a dark chrome surround and vertically-oriented fog lights. And because nothing says off-road badass like red recovery hooks, of course there's a pair peeking out from under the tweaked lower bumper. Otherwise, all the All Terrain kit carries over, like the tuned suspension with Advanced Hill Descent Control, transfer case skid plate, automatic locking rear differential, and 31-inch Goodyear Wrangler DuraTrac® tires on 17-inch aluminum wheels. Inside, the headrests are embroidered with AT4 logos, and Kalahari stitching is exclusive to this trim. GMC also announced a more polished Denali trim, without providing any photos. The coming pickup adopts a grille with a "more sculpted and layered pattern," plus five-inch chrome assist steps, and 20-inch Diamond Cut aluminum wheels that we'll assume come in a different pattern than the current 20-inch Diamond Cut aluminum wheels. The cabin goes upscale with open-pore ash wood trim and aluminum trim, a new Cocoa/Dark Atmosphere color theme, and unique stitching. Both the AT4 and Denali offer the same two engine choices. There's either the 3.6-liter V6 throwing out 308 horsepower and 275 pound-feet of torque, shifting through an eight-speed automatic, or the 2.8-liter Duramax diesel producing 181 hp and 369 lb-ft, shifting through a six-speed auto. The 2021 trucks will be available later this year, pricing to be announced closer to the on-sale date. The 2020 Canyon All Terrain starts at $37,695, the 2020 Canyon Denali starts at $41,595.
