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.

Mark Reuss: GM can't afford product 'misses,' has 'thought about' CT6 V-Series

Mark Reuss is a busy man. He oversees General Motors' global product portfolio, an all-encompassing task for a company that sold more than 9.9 million cars and trucks last year. When GM launches a well-received product, like the road-going rocket ship that is the Chevrolet Corvette Z06 – he gets credit. When the company stumbles with the slow-selling Chevy Malibu or grapples with fallout from the decade-old Saturn Ion and its flawed ignition switch, he gets blamed. GM owners, the press and sometimes the federal government, demand answers. Bob Lutz famously held the job before Reuss. So did Mary Barra, who's now GM's chief executive. There's a New GM, but the lineage is connected to a long history. When he's not thinking product, Reuss, an executive vice president, also runs the purchasing and supply chain for the company, which is still one of the largest industrial empires in the world. We caught up with Reuss on the floor of the New York Auto Show, where GM had just rolled out two crucial new products: the 2016 Cadillac CT6 and the 2016 Chevrolet Malibu. Speaking with a small group of reporters, Reuss delved into a variety of subjects, including the new Malibu, Cadillac's future (he thinks the ATS-V is going to "flame the M3 and M4"), and other topics. On fixing the Malibu: "We can't miss. We can't have those kinds of misses [like the previous generation] on our cars and crossovers and trucks. We can't do that. If we do that, we give a reason for someone to go buy something else. It's that simple. "On a car like the Malibu we have a chance to really fix all of that, which we have, and then lead. Then you've got a real opportunity there. So that's what we've really been focused on here – to fix those things." He later added: "We need that car here to transform Chevrolet desperately because it's the heart of the market. And when you think of Chevrolet, people will come back and think about what we did with the [new] Malibu and the Cruze... It's hugely important to us." On Cadillac: "If we go out and try and out-German the Germans, it's probably not going to work. We've got an opportunity here generationally where there's a lot of people younger than me that have parents that drove BMWs and Mercedes, and I think there's an opportunity there for those people to drive something different than what their parents did, and I think that's always been an opportunity in the auto industry if you look at the history of it.

Forget everything you know about Cadillac V

Cadillac rolled out the CT4-V and CT5-V performance sedans to a rather confused group of journalists last night. What are these cars? Only 355 horsepower in the CTS-V replacement? And just 320 horsepower for the ATS-V successor? Surely, there's something out of place — you can get up to speed with all the details here. Cadillac understood our confusion and explained what was going on rather quickly. The explanation means you have to forget everything you know about what "V" means for a Cadillac, though. Any Cadillac with the singular "V" badge on it previously has denoted the absolute top-tier of performance for that particular model. The CTS-V had the Corvette Z06 engine in it and made 640 horsepower. The ATS-V had a boosted 3.6-liter V6 good for a raucous 464 horsepower. They were equivalent to BMW M, Mercedes-AMG or an Audi RS. We're not talking about the lesser M or AMG models, either. No, the last Cadillac Vs were meant to compete with cars like the C63 or M3, the top-tier of performance in those brands' lineups. This is where you're going to have to start re-learning, because that's no longer the case for a Cadillac with a V badge gracing the rear end. What Cadillac has essentially done is demote what V means, with the intention of offering "something else" above it. With this new strategy, we'd equate a Cadillac V to something like an AMG 43, M340i, or Audi with an S badge on it. Cadillac has even come out with a car similar to this strategy before in the V-Sport. That didn't confuse everybody, though, because the name was different, and the strategy was clear. Now, Cadillac V is just a small stepping stone to these mysterious high performance cars still to come. We asked for any information concerning these future track-ready, fire-breathing monsters, but mum is the word for now. The naming strategy for something above a V is uncharted territory, and it'll also force everyone to learn what the top of the Cadillac lineup is all over again. Cadillac CT5-V View 6 Photos Why confuse folks like this? Cadillac wants to take advantage of the V brand cache in more of its lineup than just two super sedans. Think future vehicles like an XT5-V, XT4-V and others like that. Now that V doesn't mean a Nurburgring-conquering 500+ horsepower luxury muscle car, it makes it far easier for Cadillac to get V badges on everything. Obviously, GM isn't the first to think of this strategy.
