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 alerting truck and sedan owners to a do-over on brake recall

A recall campaign intended to address issues with braking systems on certain 2019 General Motors trucks and sedans may have introduced a new issue, the automaker has acknowledged, and thousands of owners driving repaired vehicles may need to return to their service departments for another update.  The update addresses a fix that was pushed out to owners of more than half a million brand-new GM trucks and sedans that could potentially lose partial braking function, according to the Detroit Free Press. The original software fix helped address situations where the vehicles' anti-lock braking systems would become disabled, which in turn would prevent electronic stability control from activating. Vehicles subject to the recall would often experience software glitches that prevented them from properly communicating the operational state of these systems, meaning drivers would have no idea that their brakes may not behave as expected in an emergency. The 2019 Chevrolet Silverado 1500, Cadillac CT6, and GMC Sierra 1500 were all recalled in the original campaign.  Unfortunately, the early version of this fix appears to have introduced yet another software glitch, indicating that the original fix did not do the trick. Those who have not yet had their cars serviced can rest easy; they will only receive the most up-to-date version of the software fix.  Related video    

Farley reacts as UAW expands strike against Ford, GM

Members of the United Auto Worker union walk out of the Chicago Ford Assembly Plant as Lance Williams from Lansing, Ill., waves the UAW flag Friday. (AP)   As the United Auto Workers walk off the job at an additional Ford and General Motors plant, Ford CEO Jim Farley addressed investors and members of the media Friday, pleading the case for the company's latest overture to the union and addressing both public and investor concerns regarding the core issues facing American manufacturing.  Farley made a public case for Ford's efforts to resolve the dispute, expressing frustration with the ongoing stalemate and noting both the concessions Ford offered before the strike began and the signing of a contract with Canada's Unifor. Farley also acknowledged UAW President Shawn Fain's success in getting the union's message out, quipping: "Shawn has been on TV more than Jake from State Farm at this point." The first-ever simultaneous strike against the Detroit Three automakers enters its third week with threats of continued expansion, but little in the way of obvious concrete progress.  "If the UAW’s goal is a record contract, they have already achieved this," Farley said. "It is grossly irresponsible to escalate these strikes and hurt thousands of families." Farley also lamented the fact that EVs have become the subject of partisan conflict, with the company's recently announced battery production facilities taking heat from both pundits and investors as Ford was forced to press pause on the venture while negotiations continue. Former President Donald Trump dropped in to Michigan this week to declare EVs the enemy of blue-collar jobs. "They've become a political football, and that's a shame," he said. Friday saw an expansion of the UAW strike to Ford's Chicago assembly plant and GM's Lansing, Delta Township, Michigan, assembly plant, covering about 7,000 workers, Fain said in an announcement, bringing the total number of workers on the picket lines to 25,000. The strike will not include any additional members at Stellantis, where talks have reportedly been more productive. The Ford and GM plants went on strike at noon Eastern today (Friday). Ford builds the Explorer and Lincoln Aviator in Chicago. GM's Delta Township plant builds Chevy Traverse and Buick Enclave. "Despite our willingness to bargain, Ford and GM have refused to make meaningful progress," Fain said in a video address Friday morning.
