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.

Cadillac and Buick boost GM's return to growth in China

BEIJING — General Motors on Monday said continued market recovery from the COVID-19 crisis helped its China vehicle sales grow 12% on year in July-September, marking the Detroit automaker's first Chinese quarterly sales growth in two years. The second-biggest foreign automaker in China by units — after Germany's Volkswagen AG — said on Monday it had delivered 771,400 vehicles in China in the third quarter. That followed a 5% fall in the second quarter, when parts of China were still emerging from virus-busting lockdown measures. GM has a Shanghai-based joint venture with SAIC making Buick, Chevrolet and Cadillac vehicles. It has another venture, SGMW, with SAIC and Guangxi Automobile Group, producing no-frills minivans and which has started manufacturing higher-end cars. Sales rose 26% for cars under its mass-market Buick brand in the third quarter versus the same period a year earlier, while those of premium brand Cadillac jumped 28%, GM said in a statement. Sales of its mass-market Chevrolet marque fell 20%. Sales of no-frills brand Wuling grew 26%, whereas those of mass-market Baojun vehicles tumbled 19%. "GM's compact models returned to four-cylinder engines and that helped sales growth," said LMC Automotive senior analyst Alan Kang, referring to an attempt to market cleaner but noisier three-cylinder versions. "Cadillac also has a more complete lineup this year." China's biggest automakers' association expects overall car sales to grow by double digits in July-September versus a year earlier. Makers such as Toyota, Honda and Geely saw sales jump in the just-finished quarter. GM has seen its China sales suffer in a crowded market and slowing economy. To revive its fortunes, it plans to have electric vehicles (EVs) make up over 40% of new models in the next five years in China, where the government promotes greener cars. The automaker's Wuling Hong Guang MINI EV, a micro two-door EV with a starting price of 28,800 yuan ($4,200), was China's biggest-selling EV in August. GM's sales fell 15% in 2019 from a year earlier to 3.09 million vehicles. The automaker delivered 3.65 million vehicles in 2018 and 4.04 million in 2017. Related Video:

First Cadillac ELR rolls off the line

Gearing up for the Belle Isle Grand Prix this weekend, General Motors invited some of the Chevrolet and Cadillac racecar drivers out to its Detroit-Hamtramck assembly plant. While there, the racers - including IndyCar Driver and Chevrolet Volt owner, Simona De Silvestro - witnessed the very first 2014 Cadillac ELR to roll off the assembly line.
These vehicles are not destined for customers, however, but instead pre-production units will be used by engineers for testing purposes. Actual production of ELR consumer models is expected to commence closer to the end of this year. As a refresher, this range-extended electric Cadillac shares much of its powertrain with the Volt but will have a sportier coupe design inspired by the Converj Concept. De Silvestro manged to snap a few images of here own, which you can see in the gallery below.
