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.

These are the fastest-selling new cars of 2024

Automakers finally appear to be back on their feet after a few years of severe instability, but that hasn’t helped all of them in the sales department. iSeeCars recently released its study on the fastest- and slowest-selling new vehicles and found that some companies are moving vehicles off dealersÂ’ lots at more than twice the pace of others. Toyota was the fastest-selling new car brand between October 2023 and March 2024, moving vehicles in an average of 39.6 days. Surprisingly, Alfa Romeo came second, averaging 41.8 days on the market. Last year, we saw a list of the fastest-selling individual nameplates overall, as opposed to this study that's ranked by brand. Fastest-selling new cars of 2024 Toyota: 39.6 days on the market Alfa Romeo: 41.8 Cadillac: 43.4 Honda: 44.2 Jaguar: 44.4 Kia: 47 Hyundai: 47.1 Subaru: 49 BMW: 49.1 Mazda: 53.1 The brands moving inventory the fastest show a strong value and desirability for buyers. iSeeCars executive analyst Karl Brauer noted, “Fast-selling brands like Toyota and Honda represent mainstream consumers seeking maximum value for their new-car dollar. Conversely, high-ranking luxury, low-volume brands like Alfa Romeo, Cadillac, and Jaguar reflect both their limited supply as well as high demand from affluent buyers willing to snap these models up shortly after they arrive on dealer lots.” Of course, there is no light without darkness, and on the other side of the list are a handful of brands struggling to move inventory. Lincoln was the slowest-selling new car company, with an average of 82.6 days to sell. Infiniti was close behind at 79.8 days, and Buick took an average of 79 days to move units. iSeeCars noted that new EVs take much longer to sell than their hybrid counterparts, at an average of 70.6 days on the market in March 2024, compared to just 49.5 for hybrids. Some of the fast-selling new brands also made the used car list. Used Hondas sold the fastest, only sitting on dealersÂ’ lots for an average of 26.1 days. LexusÂ’ used cars sat for 26.3 days, and Toyota moved its used inventory in an average of 27.4 days. By the Numbers Green Alfa Romeo Cadillac Toyota Car Buying

Cadillac dealers frustrated over Escalade production snarls

Lincoln went through it during the launch of the MKZ last year, Jeep went through something similar with its Cherokee launch, and now the 2015 Cadillac Escalade has apparently caught the bug: dealer delivery delays because of quality control checks. Automotive News reports that Cadillac dealers have been waiting three times longer than usual - a month or more - from the time an Escalade leaves the assembly line to when it gets delivered. Worse, dealers are saying they don't always know where their vehicles are in transit, or when they are set to arrive. The situation has upset customers who have put down deposits and things have gotten so bad that some dealers have reportedly stopped taking pre-orders.
Cadillac says it has the delay, called "dwell time," down to two weeks, and it expects to cut that to a week by the beginning of September. The company said "a lengthy quality-assurance process on some interior parts" has caused the lag, the report citing additional issues with figuring out which vehicles should be delivered first. A spokesman said that more trucks have been put in the distribution system to work through the backlog, but it's clear it's still going to take some time to set things right, with one dealer telling AN that cars ordered in February and March still haven't arrived.
Brand chief Kurt McNeil said additional personnel are at the Escalade's Arlington, Texas factory to speed up the checks, and spreadsheets tracking every order have been distributed to field staff. Even with the snafu, though, the Escalade is Cadillac's best seller through July.
