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.

Spy photos show Trump's new Cadillac-badged rolling fortress

Development on the new presidential limo, oh-so appropriately nicknamed The Beast, is moving along at a GM proving ground. We got a brief glimpse of the Cadillac-badged rolling testament to safety and security late in February thanks to some clever drone work. We now have a new batch of ground-level photos that show the limo cruising around, presumably being put through the vehicle equivalent of boot camp. Currently, President Trump is making do with the first-generation Beast. While still likely safer than anything else on the road, it's starting to be a bit dated. In addition to the updated styling that makes it look like a comically oversized Cadillac CT6, The Beast v2.0 is likely packing a whole new suite of technology and safety equipment. That's just an assumption, as there's no press release with a full list of features. We can't imagine that the government would want everyone knowing what's beneath The Beast's skin. Expect Trump's ride to have reinforced doors, extra-thick glass, and even a filtration system that would protect against a biological attack. There's speculation that it's equipped with tear-gas cannons, similar to one of James Bond's rides. Even the relatively normal-looking tires are likely to be strengthened in some way, allowing them to still roll if punctured. Add up all of the extra reinforcement, and the truck-based ride is likely to have a mass that's equivalent to a small moon. All that tech doesn't come cheap. Expect The Beast to cost taxpayers somewhere around $1.5 million. Hey, it's still less than the new Bugatti Chiron.

GM to make most cars LTE hotspots for 2015

General Motors isn't the first automaker to deliver in-car Internet access, but a proposed plan announced today could make the technology more widespread than any of its competitors have offered. By the 2015 model year, most Chevrolet, Buick, Cadillac and GMC products in the US and Canada will offer 4G LTE mobile broadband access. Initially, GM will just be pairing with AT&T to deliver this service, but additional carriers will be revealed in the future.
Current in-car Wi-Fi hot spots are limited to 3G, but GM says that 4G LTE is 10 times faster than 3G service and will allow for full Internet access, including streaming video for entertainment as well as services like real-time traffic updates and navigation driving directions. There is also no need for a paired smartphone with this new system, which should make it easier to use, and GM and AT&T will also be working together to develop new apps for customers.
Buyers can expect to start seeing 4G LTE in their cars starting next year, and GM is already planning to expand the service to other global markets as well. All of the information from GM's announcement is posted in a press release below.
