Next-gen GM SUVs caught wearing new boxy bodies [w/video]

We recently drove the brand-new 2014 Chevrolet Silverado and found it to be vastly improved compared to the outgoing model. And now that The General's pickup trucks have been squared away, it's time to focus our attention onto their passenger-friendly companions, the Chevrolet Tahoe and GMC Yukon (above).
Our spy photographers have passed along a huge smattering of photos (and a video), showing the new SUVs out testing. Both the short- and long-wheelbase models were spied, and while the overall shape of the vehicles hasn't changed all that much, we expect the updates to be substantial. In addition to new powertrain options, like GM's new small-block V8, we expect the interiors of both SUVs to get massive makeovers, providing better materials throughout their cabins and quieter, more refined environments. We even hear that some trick new suspension developments may be in store for upper-end models.
Visually, these spy shots allow us to see a couple of new details on the SUVs' front and rear fascias, including LED running lamps on the Yukon and some interesting LED taillamp treatments. Of course, the obvious third party missing from this set of photos is the Cadillac Escalade, but as we reported earlier, GM is working to further differentiate the 'Slade from the rest of the fullsize SUV lineup, and is working to make the new model "much less ostentatious."

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.

2021 GMC Yukon will pull a 180 thanks to a Hurricane Turn feature

GMC isn't a hip, young startup, but its engineers are out to prove it's possible to teach an old dog new tricks. The next-generation Yukon will offer adventurers seeking a quick turn-around a "Hurricane Turn" feature that functions a lot like Rivian's Tank Turn technology. The two systems use different hardware to perform a similar action. We didn't hear anything about the Hurricane Turn feature during the Yukon's unveiling because GMC planned to keep it under wraps until later, but an eagle-eyed report at Motor Trend uncovered it and quizzed the firm. It's real, and it's engaged when the driver switches the stability control system off, energetically turns the steering wheel in either direction, and mashes the accelerator pedal to the floor. The Yukon needs to be on a loose surface, too. If you're turning right, the on-board computer applies braking power to the passenger-side wheels to prevent them from spinning, while the engine continues to turn the driver-side wheels to rotate the Yukon on its own axis. The exact opposite happens if you're turning left. It's clever and relatively simple; there's no extra hardware required to enable the feature, though it shows the next Yukon is far more advanced than its predecessor. It goes without saying that only four-wheel drive models will receive the Hurricane Turn feature. There's no word yet on whether it will be compatible with all three engine options, or if it will be limited to a certain trim level. GMC will publish additional details about the system, and hopefully a video of it in action, in the coming months. Rivian, on the other hand, leveraged its four-motor electric powertrain to teach the R1T (and presumably the R1S) how to pull a 180. The right wheels turn in the opposite directions as the left wheels – hence the name Tank Turn – to spin the truck around like a CD in a Walkman. Its system doesn't use the brakes. The 2021 Yukon is due in showrooms in the summer of 2020, and Amazon-funded Rivian won't start making the R1S until the end of 2020 at the earliest, so GMC will beat its younger rival to the punch. What remains to be seen is how often motorists use either function. We're betting not very once the initial novelty wears off. Related Video:
