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's Mark Reuss explains why a performance Cadillac ELR-V won't happen

Hey, I've got enough things to worry about. That's one interpretation of General Motors executive vice president Mark Reuss' response to a question posed by Driving the Nation about the recently-introduced Cadillac ELR plug-in hybrid. Reuss said GM will "definitely expand the tuning envelope" for the ELR. The question was whether GM would consider adding magnetic ride control to the quite-powerful-for-a-plug-in Caddy, creating an "ELR-V" model in the process. Reuss' non-answer: "Good question, can't really answer that," but then elaborated that magnetic ride control uses up "a lot" of power otherwise spoken for in terms of providing the longest electric-only range possible. Interestingly, he did add that GM will "definitely expand the tuning envelope" for the ELR, as you can see in the video below. With the model retailing for north of $75,000, fewer than 60 percent of US Cadillac dealers were carrying the ELR as of last month and just 99 ELRs were sold during the first two months of the year. In an effort to sell more vehicles, GM said in January that it would offer the ELR for a 39-month lease for $699 a month for qualified lessees and with a $5,999 down-payment required.
