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.

Ghostbusters trailer stars Ecto1 and a quartet of actresses

"Um... you didn't disclose that the vehicle was going to be a hearse," says funnywoman Melissa McCarthy in the brand-spankin'-new trailer for the upcoming Ghostbusters reboot. Traditionalist fans may be similarly angered by the vehicle's basis, since the original Ecto1 was an ambulance, not a vehicle for the dead. Leslie Jones' response to McCarthy wasn't meant to answer those critics, but it does a good job of it anyway: "It's a Cadillac!" Naturally, there's a lot more to look at in the new trailer than just the Ecto1. There are, obviously, ghosts. Lots of 'em, in fact. There's also an opening piano sequence that's pretty darn great, but we ought to warn you that if you watch the video up above, you're going to be humming the theme from Ghostbusters for the rest of the day. We're sorry, but it simply cannot be avoided. You've been warned. Related Video:

2021 Cadillac Escalade Review | What's new, features, photos, Super Cruise price

The 2021 Cadillac Escalade is a heavyweight mammoth that is unapologetically bold and quintessentially Escalade. Its general shape and design still plummets from the same tree as a Chevy Tahoe or Suburban, but there’s no mistaking this SUVÂ’s new look for anything but a bejeweled, bold and brash Cadillac. That said, it does take advantage of all the lovely new engineering enhancements made throughout the GM SUV lineup, including the latest-generation magnetic dampers and a new air suspension system. Combined with the long-awaited independent rear suspension design, these pieces bring the EscaladeÂ’s ride up to par with the most comfortable and luxurious SUVs on sale today.  In addition to the ride improvement, CadillacÂ’s new interior is a tech and luxury fortress befitting its price. The new triple OLED screens scream luxury, and the design makes it competitive with LincolnÂ’s gorgeous Navigator once more (a far more comfortable and usable third-row seat helps in that regard, too). Under the hood, there's an interesting new powertrain option with this generation of Escalade: a 3.0-liter turbo-diesel inline-six that brings decent fuel efficiency (23 mpg combined at its best) to a class of vehicle that typically achieves horrendously low figures. In total, with more space, more efficiency and vast improvements in every other category, the 2021 Escalade is poised to stand toe-to-toe with other luxury behemoths.  WhatÂ’s new for 2021? The Escalade is all-new for 2021. ItÂ’s the modelÂ’s first big redesign since the 2015 model year. 2021 Cadillac Escalade Sport Platinum View 60 Photos What are the Escalade interior and in-car technology like? The Escalade doesn't quite achieve the same elevated sense of fashion as Lincoln does with the Navigator, but it nevertheless makes a statement with its tech-forward take on luxury. The 38 inches of curved OLED screens we covered in our Escalade infotainment review dominate the dash in a brazen display of opulence. Large swaths of wood trim stretch across the dash horizontally and also adorn a substantial part of the center console. Your color and design options are plentiful, but it all depends on trim. The purple Dark Auburn is fantastic, and the light-and-airy Whisper Beige is another great option (pictured below). Real wood trim in various colors and patterns can be had, and varying levels of leather and suede coverage are available.
