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.

Cadillac Lyriq shown in pre-production form for the first time

A single photo of the upcoming Cadillac Lyriq testing in camouflage was posted on LinkedIn by Mahmoud Samara, Cadillac’s vice president of sales, service and marketing. ItÂ’s significant, because we havenÂ’t seen a single photo of the actual pre-production Lyriq yet. All Cadillac has shown us so far is a concept-like version of the crossover that is destined for production. This photo of the crossover done up in camouflage gives us the first impression of how Cadillac is transforming the Lyriq from concept car to production car. ItÂ’s moving at speed with some motion blur in the image, but we've lined both it and the original production-intent prototype up atop each other below for you to compare. In a way, this photo is a lesson in how deceiving camouflage on a car can be. The undisguised Lyriq has exponentially more presence and pizzazz than the one in black and white speckled wrappings. Given just the camo car, weÂ’d be able to discern that Cadillac is working on a large, coupe-like electric crossover, but the details would remain a mystery. The dramatic window line is totally obscured by the camo car, and so is its wild rear taillight that wraps up into the giant rear pillar. That huge rear blade/pillar is one area that could see change from the Lyriq photos weÂ’ve seen so far, too, as it looks like a massive blind spot for the driver. Other notable differences include regular-sized wheels and tires, a potentially higher roofline (for more practical headroom and cargo space) and actual side mirrors instead of the camera mirrors. Does it all look slightly less futuristic? Sure, but remember that the camouflage is there to disguise and trick the eye. One element that does look completely carried over is the massive screen inside. You can see the monolith stretching across the dash from far away. ItÂ’s likely that we get a full array of spy shots from one of our usual sources soon with far more angles to look at. SamaraÂ’s announcement in his post made it clear that pre-production testing is underway at GMÂ’s testing facilities. Cadillac has previously said that the Lyriq would officially go on sale in late 2022, so expect more disguised prototypes until then.

GM shows off 'digital vehicle platform' enabling more in-car tech and OTA updates

It appears to have dropped the sobriquet "Global B," but General Motors' new electrical architecture has bowed in drawings and video. This is the "digital vehicle platform" GM president Mark Reuss spoke to Reuters about in 2015, saying it would move a great deal of a vehicle's computer work to the cloud and enable over-the-air updates. Reuss took the microphone for the debut, too, saying, "Our new digital vehicle platform and its eventual successors will underpin all our future innovations across a wide range of technological advancements, including EVs and expanded automated driving." The system will go into production later this year, appearing in dealerships first either on the 2020 Cadillac CT5 or the mid-engined 2020 Chevrolet Corvette. Yes, these are the same electronics cited for delaying the launch of the C8 Corvette over excessive draw, security and getting the more-than-100 computer modules to communicate seamlessly. When Car and Driver asked about that, GM replied with "No comment." Volkswagen's having the same issues with the Mk8 Golf right now, though, so GM isn't alone, and this will be the new normal among OEMs for a while. What's certifiable is that the new architecture is robust enough to handle 4.5 terabytes of data per hour, which is five times what GM's current wiring can handle. And thanks to Ethernet connections of 100 Mbps, 1 Gbs and 10 Gbs, communication within and without the vehicle happens much faster. The advances mean better screen resolutions, better battery management for hybrids and electric vehicles, the capability for over-the-air updates and "functionality upgrades throughout the lifespan of the vehicle." Cadillac's Super Cruise has already been lined up as a leading candidate for constant improvements in the driving assistance suite, a key part of GM's "vision for a world with zero crashes, zero emissions and zero congestion." And whenever GM decides to take the plunge, it will mean a 48-volt electrical system. More than 300 specialists worked on the digital platform, and security was a huge part of the task. We've already heard that GM consulted with Boeing and military contractors on how to prevent hacking. The carmaker has an internal Product Cybersecurity group that reached out to the research community, and created a "bug bounty" program to crowdsource uncovering any flaws.
