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.

2014-15 Chevy Impala recalled over airbag fault

Over 5,700 current-generation Chevrolet Impala sedans are being recalled, General Motors announced today. The fullsize four-doors suffer from an issue with the front seats. According to a report from The Detroit News, a production problem during the seat steaming process could cause "a calibration error in the electronic control module." In turn, that would cause an issue with the Automatic Occupant Sensing system. The AOS is a crucial element, as it looks at the weight on the front seat to determine whether the airbags should be armed or not. According to a bulletin from the National Highway Traffic Safety Administration, a problem with the system could mean that the airbags deploy when they shouldn't, such as when there's a child or infant seat mounted in front. The problem is limited to 2014 and 2015 models that have both heated and vented front seats. Owners will be asked to report to dealers for a free recalibration and ECU reset. Scroll down for the official bulletin from NHTSA. Related Video: Report Receipt Date: JUL 24, 2015 NHTSA Campaign Number: 15V465000 Component(s): AIR BAGS Manufacturer: General Motors LLC SUMMARY: General Motors LLC (GM) is recalling certain model year 2014-2015 Chevrolet Impala vehicles manufactured April 15, 2013, to June 19, 2015, equipped with front vented-heated passenger seats. Accordingly, the Automatic Occupant Sensing (AOS) system may fail to suppress the front passenger air bag if a child seat is in the front passenger seat. These vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) No. 208, "Occupant Crash Protection." CONSEQUENCE: If the front passenger air bag deploys with a child seat in the front passenger seat, it increases the risk of injury to the child. REMEDY: GM will notify owners, and dealers will correct the calibration-learning error by preconditioning the empty seat, and also resetting the ECU to a seat zero-value, free of charge. The manufacturer has not yet provided a notification schedule. Owners may contact Chevrolet customer service at 1-800-222-1020. GM's number for this recall is 15400. NOTES: Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.

Hurst Edition Trans Am proves the Screaming Chicken will rise from the ashes

It seems the Pontiac Trans Am steadfastly refuses to die. Ever since Chevrolet was granted a retrofied Camaro to compete with the Ford Mustang, Pontiac lovers have lamented the loss of this 1970s icon. And, looking at the Hurst Edition from Trans Am Depot, shown here at the 2012 SEMA Show, may explain what all the fuss is about.
It's not going to appeal to everyone's muscle-car tastes, but there's certainly room for a brash-and-bold black-and-gold Special Edition in many a Trans Am lover's garage. After all, if you want the keys to a custom pony car, you'll certainly get noticed in this one. If this scheme isn't your bag,, you can alternatively order your Hurst Edition in white and gold or silver and black. Oh, and don't forget a color-coordinated Screaming Chicken on the hood.
No matter which way you choose to go, your inner Burt Reynolds will appreciate the Eibach suspension kit, forged wheels with Pirelli PZero tires, functional shaker hood, fender air extractors, rear spoiler and, of course, a Hurst shifter inside. The interior is emblazoned with all manner of special touches, including a Hurst dash plate and T/A stitching on the Katzkin two-tone leather seats.
