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 Chevrolet Cruze TD fires up its new diesel motor

Ever since General Motors confirmed plans to produce a diesel-powered Cruze back in 2011, we've been eagerly awaiting its arrival. And as part of the 2013 Chicago Auto Show, Chevrolet has pulled back the cover on its oil-burning compact sedan, set to go on sale in the near future with a starting price of $25,695, not including $810 for destination.
The heart and soul of the Cruze TD (that's its official name) is a 2.0-liter turbo-diesel inline four-cylinder engine rated at 148 horsepower and 258 pound-feet of torque, mated solely to a six-speed automatic transmission. The engine also has an overboost function that will increase torque to 280 lb-ft for up to ten seconds. The full brace of official specs haven't been released, but GM tells us that highway fuel economy will come in at 42 miles per gallon. If that number sounds familiar, it's because the Volkswagen Jetta TDI has the exact same rating. Unlike the Jetta, however, the Cruze TD can run on B20 biodiesel, where as the Volkswagen can only accept B5.
Model-specific changes to this 2014 Cruze TD include an aero kit and unique 17-inch alloy wheels. Inside, there's a full leather interior, and Chevrolet will provide two years of complimentary scheduled maintenance, not to mention a 100,000-mile powertrain warranty.

GM might lose 90-year U.S. sales crown over chip shortage

Automotive News editor Nick Bunkley tweeted on October 1 that according to AutoNews data, General Motors "has been the largest seller of vehicles in the U.S. every year since passing Ford in 1931." With automakers having turned in light car and truck sales data for the first three quarters of 2021, GM's 90-year-run might not reach 91. According to AN figures, Toyota was 80,401 vehicles ahead when the October workday started. Worse, GM is so far behind its historic pace that it might only sell enough light vehicles in the U.S. to match its numbers from 1958.  Meanwhile, the New York Times put a few more salient numbers to the pain GM and Toyota are enduring alongside the the rest of the industry. GM sold 33% fewer cars in Q3 2021 than it did in Q3 2019 during the dark days of the pandemic, 446,997 units this year as opposed to 665,192 last year. GM's Q3 2020 was only down 13% on Q3 2019. Over at Toyota, the bottom line showed a 1% gain in Q3 2021 compared to 2020, with 566,005 units moved off dealer lots. The finer numbers show two steps forward and one step back, though; Toyota's September sales were down 22% compared to last year.  GM remains optimistic about what's ahead, GM's president of North American operations telling the NYT, "We look forward to a more stable operating environment through the fall." We'd like to see that happen, but we don't know how it happens. The chip shortage said to have been the inciting incident for the current woes isn't over, and not only can no one agree when it will be over, the automakers, chip producers, and U.S. government still can't get on the same page about who needs what and when. Looking away from that for a second shows articles about "No End In Sight" for supply chain disruptions in early September, before China had to start working through power supply constraints, global supply chain workers started warning of a "system collapse," and roughly 500,000 containers sat waiting to be unloaded at Southern California ports — a record number seemingly broken every week. And back to chips, we're told just a few days ago the chip shortage is "worse than we thought."   For now, the NYT wrote that GM dealer inventory is down 40% from June to roughly 129,000 vehicles, and down 84% from the days when dealers would cumulatively keep about 800,000 light vehicles in stock. However, GM just announced it would have almost all of its U.S. facilities back online next week, although some would run at partial capacity.
