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.

2023 GMC Sierra Review: Upscale and off-road capable

Pros: Quiet and torque-rich Duramax diesel; premium interior; big touchscreen on most trims; great trailering tech Cons: Worse ride than most rivals; AT4X priced like a Raptor but doesn't go like a Raptor The 2023 GMC Sierra half-ton pickup is a slightly more upscale cousin of the Chevy Silverado, but didn’t always feel like it. After a refresh last year, the Sierra actually delivers on the upscale part, for the most part of the equation with a comfortable, high-quality interior and better technology in most trim levels. ItÂ’s massively configurable, with four available engines and five different cab/box combinations. ItÂ’s also quite capable off-road with that AT4, AT4X and the soon-to-arrive AT4X AEV Edition. WeÂ’re fond of the diversity of tech available in the Sierra, whether itÂ’s the Google-powered infotainment with large, easy-to-use screens, a clear head-up display, numerous camera feeds for trailering and off-roading, or GMÂ’s Super Cruise advanced driver assistance system. We just wish that last one was available on more than just the Denali trims. If youÂ’re looking for a truck whose capability is matched by its livability, the GMC Sierra is worthy of your consideration, though you can find better ride quality in other brands (we enjoyed the ride in the AT4X, however). And while the AT4X has some true off-road capability, if youÂ’re looking for a Baja-blasting supertruck, though, youÂ’ll find better with the Ford F-150 Raptor and Ram Rebel TRX. If you donÂ’t need the nicer interior or extra tech, you might find something more matching your needs and pocketbook with the Ford F-150, Ram 1500 or even GMÂ’s own Chevy Silverado. ItÂ’s hard to go wrong with any of those nameplates.

After some pleasant updates for the 2022 model year, the changes for 2023 are relatively minor. The price went up, unfortunately. The available 3.0-liter Duramax turbodiesel has been revised for more power and efficiency. Later in the year, the AT4X AEV Edition will add even more off-road capability to this luxurious pickup. There are also some new exterior colors available, a new Graphite Edition for the Pro trim, and new 22-inch ultra-bright wheels for the Denali Ultimate.

2024 GMC Sierra HD AT4X and Extreme AEV muscle their way into the lineup

The new AT4X variant of GMC's 2024 Sierra HD pickup series officially joins the stable this week, giving pickup truck box-checkers yet another off-road trim to chase. Well, two trims, technically, as GMC took the opportunity to announce that the AT4X will also be offered with an upfit package from American Expedition Vehicles, appropriately named the Extreme AEV Edition that takes its cues from the same package offered on the Sierra 1500 AT4X. And with its introduction, the 2024 GMC Sierra HD lineup is now complete.  GMC's Sierra AT4X models mirror the ZR2 packages offered on the updated Chevrolet Silverado. If you paid any attention at all to the Silverado HD ZR2's introduction earlier this month, you'll be familiar with the formula. Key upgrades include a 1.5-inch factory lift, standard electronic locking rear differential, Multimatic DSSV shocks and 35-inch Goodyear Territory all-terrain tires. It also gets beefier skid plates —  both the steel protecting the transfer case and the aluminum piece up front. With the updated 6.6-liter Duramax diesel, GMC says it'll tow up to 18,500 pounds.  "GMCÂ’s AT4X trim, which will be available across the entire GMC truck lineup, offers customers more premium and capable choices when it comes to ‘do-it-allÂ’ capabilities," said GMC VP Duncan Aldred. "Each model delivers unique strengths, with the all-new Sierra HD AT4X taking it to the max, enabling you to go virtually anywhere, with the towing power to bring your recreational toys, gear or camper along for the journey." And by "do it all," he means all the luxury stuff too, judging by the Obsidian Rush interior, which GMC says includes massaging leather front seats and real ash wood trim. The better from which to feel the shove of the AT4's two available 6.6-liter engines, one a gasoline-burner rated at 401 horsepower and 464 pound-feet of torque, the other a Duramax turbodiesel making 470 horsepower and 975 pound-feet of torque. You'll need the latter if you want to hit GMC's advertised towing capacity.  And don't forget the Extreme AEV Edition, which will surely come with a Denali-rivaling (and still TBA) price tag. The stamped steel bumpers stand out right away, as do the integrated front recovery points and winch mount. The package also adds more skid plates protecting the steering gear and transfer case. Its 18-inch "Salta" wheels are also unique.  GMC says it will be cranking out 2024 Sierra HD AT4Xs and Extreme AEV Editions by the third quarter.
