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 removes start/stop from full-size trucks and SUVs with V8 engines

GM is removing start/stop technology from a number of its popular full-size SUVs due to the ongoing chip shortage. This follows the removal of cylinder deactivation technology from some of its trucks, which was also due to the chip shortage. GM Authority first reported the news, but we’ve just confirmed everything with a GM spokesperson.  The following 2021 model year vehicles will be affected: Chevy Tahoe, Chevy Suburban, GMC Yukon, Cadillac Escalade, Chevrolet Silverado 1500 and GMC Sierra 1500. Only versions of those vehicles built with the 5.3-liter V8 or 6.2-liter V8 and mated to the 10-speed automatic will have the tech removed from them. Only vehicles manufactured on or after June 7 will be affected. “By taking this measure, it will enable us to continue production of our high-demand full-size SUV and pickups as the industry continues to rebound and strengthen,” GM said in a statement. Those who ultimately buy one of these vehicles without start/stop technology will receive a $50 discount off MSRP for their troubles. Losing this fuel-saving tech could be a big negative for some, but we know many folks turn it off anyway. Not having to press the button to deactivate start/stop every time could actually be a positive if youÂ’re part of the camp who does that already. 2021 Cadillac Escalade Sport Platinum View 27 Photos On the downside, GM says “most of the affected vehicles will experience a minor reduction in fuel economy.” We donÂ’t have revised window stickers in hand to know how each model will be affected, but any 1 mpg reduction will be rather impactful for vehicles rated as low as these trucks already are. Any reduction will be seen in the city mpg rating, so take the kind of driving youÂ’re going to be doing into account before purchasing. When it comes to greenhouse gas compliance rules, GM says it doesnÂ’t foresee this impacting the companyÂ’s average fleet score. It also intends to begin adding start/stop back to these models as soon as possible, but there will be no retrofit effort made to fit the tech to vehicles already built without it. “Our supply chain organization continues to make strides working with our supply base to mitigate the near-term impacts of the semiconductor situation,” GMÂ’s statement reads. “GM continues to leverage every available semiconductor to build and ship our most popular and in-demand products, including our highly profitable full-size trucks and SUVs for our customers.

Deep discounts — $12K, $13K, $16K — are fueling a pickup price war

Heavy discounts of up to $16,000 per vehicle are fueling a "truck war" among full-size pickups sold in the United States by the Detroit Three, a Reuters analysis shows. Strong U.S. sales this year of the highly profitable big trucks have helped offset lagging passenger car sales. But it is not clear how much of the truck demand is linked directly to ample factory incentives and dealer discounts, or how far sales might decline without those subsidies. A Reuters survey of Ford, General Motors Co's Chevrolet and Fiat Chrysler Automobiles's Ram truck dealers across the United States indicates stores are offering deep discounts the country's bestselling full-size pickup trucks. "The walls are not crashing down on full-size trucks," said Sam Fiorani, vice president of global vehicle forecasting at AutoForecast Solutions in Chester Springs, Pennsylvania. Detroit-based automakers want to keep cranking out their high-margin trucks, he added, and "giving up a little of the profit is the cheapest way to do it." Stores are offering discounts of up to $12,000 on the 2018 Ford F-150, which remains the best-selling vehicle in the country, recording more than 80,000 sales in May. Discounts run up to $13,000 on the 2018 Chevrolet Silverado and as high as $16,000 on the Ram 1500. Average transaction prices for full-size pick-ups range from around $42,000 to $45,000, industry analysts and automakers say. All three companies are spending furiously - GM and Fiat Chrysler to help sell off carryover 2018 trucks to prepare for redesigned 2019 models, and Ford to sustain its long-held sales crown. A supplier fire that temporarily shut down production of the F-150 last month "changed the game," said Jeff Schuster, senior vice president of forecasting at LMC Automotive in Troy, Michigan said. The supply halt nudged Ford's crosstown rivals "to ratchet up incentives on the current models to go after weakness at Ford," he said. Deals advertised on the companies' official websites range from rebates and low-interest loans to ultra-cheap lease rates, but they are not telling the whole story. Ford, for instance, advertises a $2,000 rebate and a $500 financing credit on sales of certain F-150 models. But James Collins Ford in Louisville, Kentucky, is offering discounts of up to $12,215 on the 2018 F-150 XLT SuperCrew 4x4. The price cuts are even steeper at a number of GM and Fiat Chrysler dealers. Quirk Chevrolet is selling the 2018 Silverado 1500 Double Cab at $13,000 off sticker.
