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.

Valet mode captures joyride in red Corvette

A man in California is among the first to catch a valet behaving badly in his 2015 Corvette using a controversial built-in recording feature. Dan Cowles told KTLA 5 when he bought his dream car, a 2015 Chevrolet Corvette Stingray, he opted for the Performance Data Recorder. The Corvette PDR uses a high-definition camera mounted in the windshield header, a microphone in the cabin and a GPS receiver that record and track the sports car's movements and sounds. They work together to produce a video with telemetry overlay, so you can see acceleration rates, lap times and g-forces. The system can be customized to show extensive performance data, or simply video of your drive like a traditional dash cam. It also comes with Valet Mode, which locks the glove box, disables entertainment and records video. The audio recording feature ran afoul of several state's recording consent laws, but this video has no audio, indicating the fix may have been as easy as turning off the microphone. Cowles dropped off his hot red 'Vette with the valets at the Segerstrom Center for the Performing Arts in Costa Mesa, CA. When he got his car back he checked the PDR and discovered footage of the valet taking a short, but intense, joyride in the garage. In the video, the valet finds a straightaway in a tiered parking garage and pushes the car to 50 miles per hour in five seconds before quickly stopping. He then parks the car without incident. The valet then gets out of the car and takes one more admiring look at the front. The valet company has yet to commented on the video, according to Fox News, but valets everywhere should be on notice; that little red Corvette you have your eye on may have its eyes on you.

Chevrolet To Oversee Restoring Sinkhole Corvettes

What Mother Earth devoured, Chevrolet plans to resurrect. The carmaker said Thursday it will oversee restoration of the classic cars swallowed by a huge sinkhole beneath the National Corvette Museum in Kentucky. General Motors Design in Warren, Mich., will manage the painstaking work to repair the eight prize vehicles, the automaker said Thursday. The cars were consumed when the earth opened up early Wednesday beneath a display area when the museum in Bowling Green, Ky., was closed. No injuries were reported. The museum was open Thursday except for the area where the sinkhole occurred. Mark Reuss, GM's head of global product development, said the damaged vehicles rank as "some of the most significant in automotive history." "There can only be one 1-millionth Corvette ever built," he said, referring to one of the damaged cars. "We want to ensure as many of the damaged cars are restored as possible so fans from around the world can enjoy them." Just how the cars will be pulled out of the ground remains to be seen, said museum executive director Wendell Strode. The local fire department estimated the hole is about 40 feet across and 25 to 30 feet deep. The hole opened beneath part of the museum's domed section. "We feel pretty confident that most of the cars can be extracted," Strode said Thursday. "And we hope and believe that with just a little bit of luck, that all eight cars can be extracted and be part of the restoration." Chevrolet spokesman Monte Doran said some of the cars look to be in good shape, while others are buried in rubble. "It will likely be several weeks until we can get the cars out and assessed," he said. The GM Design team has helped restore other historic cars, but the Corvette project looks to be its biggest, he said. "These Corvettes are part of our history, and they want them restored properly," Strode said. "We're thrilled they're doing this." The cars looked like toys as they plunged into the hole, piled in a heap amid dirt and concrete fragments. The museum owns six of the cars while two - a 1993 ZR-1 Spyder and a 2009 ZR1 Blue Devil - are on loan from General Motors. The other cars damaged were a 1962 black Corvette, a 1984 PPG Pace Car, a 1992 White 1 Millionth Corvette, a 1993 Ruby Red 40th Anniversary Corvette, a 2001 Mallett Hammer Z06 Corvette and a 2009 white 1.5 Millionth Corvette. Pictures of the sinkhole showed a collapsed section of floor with multiple cars visible inside the hole.
