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:    

GM recalls 638,000 U.S. SUVs, trucks for unintended braking

WASHINGTON — General Motors is recalling 638,000 U.S. sport utility vehicles and pickup trucks because a wheel-speed sensor could fail and cause unintended braking, it said Thursday. The recall covers 2015-2020 Chevrolet Suburban, Tahoe, and Yukon and 2014-2018 Chevrolet Silverado 1500 and GMC Sierra 1500 vehicles equipped with a 5.3-liter engine, a 3.08-ratio rear axle and four-wheel drive. The sensor failure could result in unintended activation of the driveline protection system, and cause unintended braking of the wheel on the opposite side of the failed sensor. That could cause the vehicle to pull to one side unexpectedly, increasing the risk of a crash, the Detroit automaker said. GM said it was not aware of any crashes relating to the issue but found 150 field claims alleging the condition caused unintended braking or lateral vehicle motion. A GM dealer in May submitted a warranty report relating to the issue in a 2018 GMC Yukon, and two days later, a GM brand quality manager submitted the report to GMÂ’s Speak Up For Safety program that tracks potential safety issues, which prompted a GM investigation and testing.

Leaked GM document shows GMC Sierra I6 diesel is more powerful than F-150's

GM told us earlier this year that the 2019 GMC Sierra would be getting a 3.0-liter I6 diesel option, but it never mentioned power or fuel economy figures. Hold the phone though, because a leaked GM Canada document just showed up online that lists out the details we've been waiting for. Originally published by TFL Truck, the 3.0-liter oil-burner supposedly makes 282 horsepower and 450 pound-feet of torque. For those who are counting, that's more than the Ford F-150's 250 horsepower and 440 pound-feet from its 3.0-liter diesel. It soundly bests the 240 horsepower and 420 pound-feet of torque from Ram's 3.0-liter diesel as well. Fuel economy is another story, though. The promotional material states that it will get 28 mpg on the highway, which is 2 mpg short of the F-150's 30 mpg — mind you, it's only capable of that magical 30 mpg figure in rear-wheel drive form. There's another caveat here, too; these are numbers for Canada, so they're not exactly finalized EPA figures. However, we wouldn't expect drastic differences between the two when the American numbers come out. The leaked documents also state the diesel Sierra will be capable of towing 7,800 pounds. That number seems remarkably low when compared to the F-150, which can tow up to 11,400 pounds with its diesel. Extra power and torque would have us assume that GM could get even better numbers than Ford, so we're going to hold our final judgment for official word. A 10-speed automatic will do the shifting on the diesel, just like on the 6.2-liter V8. Since the Chevy Silverado is also expected to get this engine, we can assume the figures would be almost, if not identical, to those we see here. We recently drove the 2019 Sierra and Silverado without the diesel engines, so go check those reviews out if you'd like to know more of our thoughts on the redesigned GM trucks. Related video:
