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.

LG Chem's troubled Chevy Volt battery plant hiring once again

The Michigan battery plant known for paying its workers to do nothing has turned things around and is now hiring more workers, specifically to do something. South Korea-based LG Chem, which runs the factory to supply the Chevrolet Volt extended-range plug-in vehicle with its lithium-ion batteries, held a job fair recently to bring on 40 new employees in order to meet higher battery demand, according to WZZM, the ABC affiliate for Grand Rapids, MI. The LG Chem factory is in Holland, MI, about 30 miles west of Grand Rapids, and it made its first batteries last year. Prior to that, though, the factory gained notoriety after a US Department of Energy (DOE) probe found that workers there were getting paid to do, well, nothing. That's because demand for the battery packs was so low that it cost less for the plant to sit idle. The DOE was conducting the probe because of its financial grant to LG Chem. But that was then and today is today. LG Chem is looking to ramp up production in advance of the second-generation Volt. That 2016 model-year version is said to have a longer all-electric range and better performance and will ride on a new chassis, but few official details have surfaced. We will know more when we get our first look at the car at the Detroit Auto Show in January.

Weekly Recap: Ford guns for 2016 Le Mans glory with new GT

On the eve of the 24 Hours of Le Mans, Ford confirmed it will return to the French endurance race in 2016 and campaign the new GT racecar 50 years after three GT40s swept the podium at the Circuit de la Sarthe. The factory will back a two-team, four-car effort that will compete in the World Endurance Championship and the Tudor United SportsCar Championship running cars operated by Chip Ganassi Racing with Felix Sabates. The GT racecar will make its track debut in January at the Rolex 24 at Daytona, and the driver lineup will be announced later. "But rest assured, there's quite a line forming out the door," Ganassi said at the announcement. The GT is the modern successor to the iconic GT40, which won Le Mans four straight years from 1966-1969. The racecar is a rolling testbed of Ford's latest technologies, including a powerful twin-turbo EcoBoost V6. The car also makes extensive use of carbon-fiber pieces and advanced aerodynamics. Ford tapped Multimatic Motorsports of Canada and Roush Yates Engines to aid in the development of the GT racer. The road-going version, which was revealed in January at the Detroit Auto Show, is also set to launch next year. It caps Ford's growing performance lineup, and the company has ambitious plans to launch more than 12 new sporty models by 2020, including hot metal like the Focus RS, F-150 Raptor, and Shelby GT350R. The GT embodies Ford's best tech, but news of its return to Le Mans immediately conjured images of the company's fierce rivalry in the 1960s with Ferrari and intense competition with Porsche. "When the GT40 competed at Le Mans in the 1960s, Henry Ford II sought to prove Ford could beat endurance racing's most legendary manufacturers," Ford executive chairman Bill Ford said in a statement. "We are still extremely proud of having won this iconic race four times in a row, and that same spirit that drove the innovation behind the first Ford GT still drives us today." Ford is going back to Le Mans. Somewhere, Hank the Deuce must be smiling.
