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.

Chevy's 6.6-liter Duramax is pretty much all new

To say there's a heated battle in heavy-duty pickups is an understatement, with Chevrolet, Ford, and Ram constantly trading blows of increased torque, horsepower, and towing capacity. The latest salvo is the revised, more powerful turbo diesel 6.6-liter Duramax V8 in the 2017 Chevy Silverado. It has 910 pound-feet of torque, an increase of 145, putting it nearly level with the Ford Super Duty. Here's a closer look at where those gains come from. How exactly did Chevrolet add all that torque plus 48 horsepower? The automaker essentially took a fine-tooth comb to the entire engine. Chevy says it changed 90 percent of the V8, and the cumulative effect of those small changes adds up to big increases. As you might guess, the turbocharger is updated. The larger unit features electric actuation of the variable nozzle turbine (VNT), and what Chevy calls a double axle cartridge mechanism that separates the VNT moving parts from the housing. That helps with heat performance as well, with a claim that the exhaust side of the turbo can run continuously up to 1,436 degrees Fahrenheit. Helping that cause are six exhaust gaskets made of Inconel - an nickel alloy that contains chromium and iron – and upgraded stainless steel for the exhaust manifold. Despite having the same cast iron cylinder block, albeit with some minor enhancements, the engine has new cylinder heads, pistons, piston pins, connecting rods, and crankshaft, which have all been upgraded to handle 20 percent higher cylinder pressures. Alongside the increase in pressure, Chevrolet also increased the cylinder head's structure with a honeycomb design. The pattern features high-strength aluminum with dual layer water jackets that not only improve strength, but also optimize water flow for better cooling. For 2017, the cylinder head also benefits from integrated plenum that aids the engine in getting more air under heavy loads. The cylinder head isn't the only component to get a minor update, as the pistons have a larger diameter pin for improved oil flow. The same detailed improvements has been bestowed to the humble connecting rods (second in our hearts only to the inanimate carbon rod). The new design has the bolts oriented roughly 45-degrees to the rod instead of parallel. The angle split design, as it's called allows for easier passage through the cylinder.

UAW Chief Shawn Fain disrupts Detroit's labor tradition

He's known to quote the Bible and Nation of Islam civil rights leader Malcolm X. He's a social media fanatic who keeps the pay stubs of his union member grandfather in his wallet. And now, Shawn Fain is representing nearly 150,000 auto workers in one of the biggest labor strikes in decades. In taking action against all three Detroit carmakers, Fain, the head of the United Auto Workers, has remade the strategy of the union he leads, choosing a bolder, much riskier path than his predecessors after he won office by a narrow margin in a first-ever direct election earlier this year. The strike started as the clock hit midnight on Friday, and followed Fain's decision to open negotiations with Ford Motor, General Motors and Stellantis simultaneously and eschew public niceties involving choreographed handshakes that famously kicked off previous negotiating efforts. The strategy is not without risk. A weeks-long strike would hit workers who live paycheck to paycheck, while the Detroit Three automakers have billions in cash to withstand the walkout. Fain, 54, has made creative use of social media, appearances on network and cable news programs and alliances with high-profile progressive politicians such as U.S. Senator Bernie Sanders, to reframe the UAW's contract bargaining as a battle to re-set the balance of power between workers and global corporations. He has rebutted automakers' concerns about labor costs by pointing out that they have poured billions into share buybacks to benefit investors. "If they’ve got money for Wall Street they sure as hell have money for the workers making the product," he said. “We fight for the good of the entire working class and the poor." In lengthy social media talks to UAW members, Fain alternates quoting Bible verses with the use of charts and graphs to dissect wage and benefit offers from the automakers - details his predecessors kept behind closed doors during bargaining crunch time. Fain, in his unorthodox approach, ran what amounted to a public auction among the companies to push each one to top the other to avoid a costly walkout. Prior UAW presidents picked just one automaker to set a pattern for the other two. Over and over, Fain has told UAW members at the Detroit Three that they can reverse 20 years of wage and retiree benefit concessions, stop further plant closures and end a seniority-based, tiered compensation system that pays new hires as much as 44% less than veteran workers.
