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 Canada recalls 159,240 GMC and Chevy trucks for faulty defroster circuit

General Motors is recalling more than 159,000 2014-2019 Chevrolet Silverado and GMC Sierra pickup trucks in Canada due to a potential fire risk. GM says the rear defroster circuit could overheat on trucks optioned with the power-sliding rear window. Thus far, there is no word on the recall's relation to U.S. vehicles. The recall, found by Automotive News, was posted to Transport Canada on June 28, 2019 with manufacturer recall No. N192220470. Included in the 159,240 vehicles are the 2014-2018 Silverado 1500, the 2015-2019 Silverado HD, the 2014-2018 Silverado LD, the 2014-2018 Sierra 1500, the 2015-2019 Sierra HD, and the 2014-2018 Sierra LD. The notice says the rear defroster circuit, specifically on trucks with the power-sliding rear window, could overheat. Because of its placement, this excess heat could cause melting, smoking, or possibly fire, in the worst case scenario. As of now, there is no official word when GM will initiate the recall and there is no official fix detailed just yet. GM suggests that owners, who will be notified by mail if their vehicles are affected, take their trucks to a dealer to remove the rear window defroster fuse as a stop-gap.  Automotive News contacted GM to find out if the problem is also found in trucks sold in the United States, but no definitive statement was made, as the investigation is reportedly ongoing. We will update this space if American vehicles are found to be included in the problem.

Next-generation Chevrolet Colorado breaks cover in new spy photos

The next-generation Chevrolet Colorado broke cover in this fresh set of spy photos this week, giving us a glimpse of what to expect when GM's compact trucks are replaced in what is expected to be either 2023 or 2024.  Thanks to its still-extensive camouflage, this prototype doesn't give away a ton about the new Colorado's styling, but in profile, it appears as though the swoopy, upswept rear cab line might become a thing of the past. We wouldn't be surprised to see the new Colorado adopt a more angular, squared-off look more akin to that of its big brother, the half-ton Silverado. The Silverado is also expected to donate what may be the new Colorado's only powertrain. Taking a cue from Ford, Chevy is expected to offer the next-gen Colorado with just a turbocharged four-cylinder engine — the new corporate 2.7T in this instance. The large, 310-horsepower four-pot can easily take over for the 3.6L V6 currently available in the GM twins and one-up the 270-hp Ranger to boot. This would mark the end of both a V6 and diesel option being offered in GM's midsize trucks, and tracks with the company's slow, silent effort to eliminate lower-margin models. We say "trucks" because, well, whatever happens with Chevy is likely to translate to GMC. The Canyon will be due for replacement at the same time, and will likely carry on as a re-skin of Chevy's offering. We're not yet certain exactly when Chevrolet will start selling the next-gen Colorado, but given the reasonably complete state of this prototype, we expect it won't be long now. Rumors suggest it could hit the market in 2023 as a 2024 model.  Related Video: The Best Midsize Pickup: Ranger vs Gladiator vs Tacoma vs Colorado
