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.

2019 Lincoln Nautilus vs 2018 Cadillac XT5: How they compare on paper

There will no doubt be endless ads touting the "first-ever" 2019 Lincoln Nautilus, which is accurate, but it's really just a mid-cycle update of an existing midsize luxury SUV attached to a greatly welcomed name change. Frankly, Lincoln could've called it the Diamond Jubilee Bill Blass and it would've been an improvement. Whatever. The MKX is dead. Long live the Nautilus. Now, speaking of SUVs with silly alphanumeric names, the 2018 Cadillac XT5 lines up remarkably well with the 2018 MKX. Besides hailing from American luxury brands, they have virtually identical exterior dimensions and similar standard engines as well. Cross-shopping seems assured. But what does the change to the 2019 Nautilus mean for how it compares to the XT5? Cosmetic changes might tweak exterior dimensions by a tenth of an inch here or there, but the interior should remain the same. The Nautilus gets a new engine, though, so check out our spreadsheet below to see if America's (and Canada's) luxury SUVs still stack up. Conclusions The switch to a turbocharged four-cylinder base engine means the XT5 and MKX/Nautilus are no longer on equal terms under the hood. While the Cadillac now has a considerable power advantage, the Lincoln Nautilus could save you hundreds every year based on its likely fuel economy (the 2.0-liter turbo engine, albeit with a different transmission, is in the mechanically similar Ford Edge). Besides the new engine for 2019, the Nautilus also gains an eight-speed automatic and an automatic stop start system. Both of those elements are already included on the XT5. It was announced that the 2019 Nautilus will start at $41,335, which compares to the base MKX at $39,960 and the 2018 Cadillac XT5 at $41,590. In other words, the Lincoln is still less expensive, but just barely. Standard feature content is also comparable, especially as the Nautilus gains standard Apple CarPlay and Android Auto, which are already standard on the XT5. So really, no matter what they're called, the Cadillac and Lincoln should continue to be neck-and-neck competitors. 2019 Lincoln Nautilus Photos View 20 Photos 2018 Cadillac XT5 Photos View 28 Photos 2018 Lincoln MKX Photos View 57 Photos Related Video: Cadillac Lincoln Car Buying Crossover SUV Luxury Comparison consumer cadillac xt5 lincoln nautilus

2019 Cadillac XT4 First Drive Review | Fashionably late

SEATTLE, Wash. — The 2019 Cadillac XT4 compact crossover debuted in New York, Cadillac's recently-adopted home, several months ago. Since then, a lot's changed. Cadillac honcho Johan de Nysschen got the boot, the economy's continued to improve, and we've changed coasts to experience the XT4. The setting is Seattle and its environs, a place that embodies the moment – a town flush with tech money and outdoor lifestyle experiences. Oh, and traffic. Lots of that. What hasn't changed is that this is a vehicle that Cadillac desperately needs. Between and below the Escalade and XT5 are vast gulfs of white space that could swallow entire crossover-focused brands. The dealers, we imagine, howled. And de Nysschen was replaced, it turns out, by a career GM exec with a penchant for building bridges with dealers. Must be a coincidence. The XT4 should please everybody involved in that power struggle. It's cute, for one, which will make for happier dealer-customer interactions. It brings appreciable but unintimidating technological advances to a brand looking to flex some segment leadership muscles. And it doesn't strictly feel like a rebadged version of a lower-tier product, a bad habit that Cadillac keeps failing to kick. We'll discuss its competition within its segment, and how they compare to the XT4, in another piece to follow. If you're wondering where the XT4 comes from, the easiest way to think about it is as a cut-down version of the basic underpinnings of the XT5, wrapped in nicely-proportioned sheetmetal. To be blunt, there's more unadorned plastic on the lower fascia and rockers than we'd like at this price point, but the rest is handsome. Large, elegant lamps sit at both ends, set off with trendy creasing and little accent vents – Sport models have clear taillight elements, while others have red-tinted lenses. The XT5, itself a newer vehicle, looks outclassed and dated instantly when put up next to its sleeker, more modern little sibling. The interior, however, is more alike than different. The major shapes are similar, as are the placement of the switchgear. The 8.0-inch infotainment screen is, as in the XT5, embedded in a slabby wedge of dash. It's still a touchscreen, but a little dial now provides an alternate way to navigate. A Qi charging panel and easily accessible, but not too prominent, USB, charging, and aux inputs reside just above. The seats in our tester, a Premium Luxury trim, are covered in a soft, warm caramel-colored leather.
