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.

2017 GMC Acadia First Drive

We're in the midst of the Second Great CUV War, and the crossovers are winning by a lot. Compact sedans are being hauled around the side of idled factories and unceremoniously shot. FCA, whose be-sweatered CEO is either omnipotent or a troll of the highest order, is organizing a last stand around profit-dense SUVs and trucks on the off chance that gas prices don't rise ever again. It's the tall wagon's finest hour, and GMC is hoping the new Acadia will capture a share of the glory. The old Lambda-platform Acadia was introduced in 2007, leading the full-size, three-row crossover charge that spawned a quartet of semi-indistinct variants, including a Saturn. (Remember Saturn?) These four were truck-like in heft and capabilities, but lighter and better-mannered than their body-on-frame counterparts – and with an unusually stout 5,000-pound towing capacity. The Lambda siblings bombarded established beachheads on the sales territories occupied by minivans and truck-based SUVs. Last year, GMC moved nearly 100,000 Acadias in the US, the best year ever for the model. Now GMC shows up with a deflated Acadia for 2017, 7.2 inches shorter overall, 3.5 inches narrower, and with a 6.4-inch-shorter wheelbase. The company has even carved something like 700 pounds out of its previously portly unibody, mostly due to the size reduction but also through an increase in the percentage of high-strength steel and the use of lighter soundproofing materials. GM's C1XX platform was launched with the Cadillac XT5 earlier this year, and this GMC version is the second to appear. There's even an available four-banger, but more on that in a bit. What remains to be seen is whether the downsized Acadia represents a leaner, meaner fighter or if GMC is sending it into battle hamstrung. Outside, the new Acadia is stealthily innocuous. Gone is some of the lozenge-ness of the outgoing Acadia, but don't fret about it standing out from the crowd. The overall styling falls into lockstep with the Sierra and Canyon. The cut of the rear window, with an upsweep at the trailing edge, emulates the brand's mid-sized truck offering. A chrome mustache cuts across the front fascia below the grille, and there's more brightwork around the front side windows and at the crease below the scallop in the doors. The taillights are more contemporary than before, with an attractive elongated C element comprised of LEDs.

2019 GMC Sierra 1500 prototype shows off differences from Silverado

Now that the new Silverado has made its debut, we're awaiting the reveal of its mildly restyled twin, the GMC Sierra 1500. While it likely won't be that different as far as capability and major equipment are concerned, we are looking forward to seeing what design changes it will have. Based on these recent spy shots, the changes will be mild, but still enough to make it visually distinctive. One of the more obvious differences will be in the front fascia treatment. Unlike the Silverado's grille that's level with the top of the headlights, the GMC's will rise above the lights, which will also yield a slight drop on each side of the hood to meet the lights. The grille is quite tall, extending far below the headlights, too. We can make out, behind some mesh, two dips on the outer edges of the grille that give the Sierra a more menacing frown. Large foglights are also found right near where the scoops for the wheel air curtains, and the headlights are unified on the edges, rather than split on the Silverado. Along the sides, the sheet metal looks relatively unchanged. At some angles, we can make out the distinctive shoulder line from the Silverado that runs up to about the rear mirrors where it stops to make room for another crease that rises up from somewhere in the middle of the front doors to lead to the front. The wheel arches are decidedly different from the Silverado's though. While the Silverado has fairly rounded arches, the Sierra's have a rear-slanted bevel to the fronts of the arches and a rounded 90-degree corner at the rears. There isn't much we can tell about the rear except for the taillights. They're quite large, and unlike the Silverado's, there aren't any areas where the sheet metal intrudes. It also appears that the tops of the taillights extend farther forward into the bed sides than the Chevy's. Because the Sierra has almost always been a mechanical twin of the Silverado, we expect it to offer the same 5.3-liter and 6.2-liter V8s, as well as the new 3.0-liter diesel inline-6. Also, being a GMC, it will likely have a flashy, chrome-laden Denali trim level. We also will see the fully revealed model soon, as Automotive News reports the debut will be on March 1.
