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.

Next-gen Chevy Cruze caught cruising in the cold

Spy photographers have caught what looks like the next-generation Chevrolet Cruze out on snow patrol. The camo could be tricking our eyes, but it look like it has an even tidier, more rounded front end and even lower fenders in relation to the top of the hood. And either a chunk of camo has been wedged between the side mirrors and the doors, or the mirrors are up for revision, too.
The door handles have been moved up the side of the car, leading the way to a rear end that grows a bit in length. If the rumors are true, the coming second-generation Cruze sits on the new D2XX platform that will replace the Delta and Theta platforms at General Motors. A global architecture, the Cruze will be the first to get it, but it will underpin everything from next Chevrolet Volt to the Equinox and could be responsible for 2.5 million units by 2018. The next Cruze is expected to begin production in GM's Lordstown, Ohio plant in the third quarter of 2014.

Chevy Volt gets customer satisfaction 'recall' for rear hatch issue *UPDATE*

Last week, General Motors has issued a "Customer Satisfaction program" for some 2011-2015 model year Chevrolet Volts to fix the manual rear lift gate not working as appropriate. According to Volt owner posts on Facebook, the problem manifests itself by the hatch not opening up all the way (sometimes worse in the cold) with some people bumping their heads. Dealers will replace the lift gate struts as part of the program. Some drivers were notified through the vehicle's OnStar system that there is a problem. GM has not yet said how many Volts are affected. *UPDATE* This program is for all 2011-2015 model year Volts. Chevrolet spokesperson Michelle Malcho told AutoblogGreen that, "This is not a recall, so there won't be any formal information posted on the GM website." The fixes will be free to affected Volt owners. Some 2010-2015 Cadillac SRX vehicles are also affected by the same problem and will also be fixed.
