2021 Chevy Tahoe, GMC Yukon fuel economy and towing capacities go official

Most of the puzzle pieces have fallen into place with GM’s new full-size SUVs, but today we have fuel economy and towing to add to the picture. Numbers for the standard 5.3-liter V8 and upgrade 6.2-liter V8 are out, but GM has held back on the 3.0-liter turbodiesel inline-six for the time being. Those numbers are most likely not ready yet. Minor improvements and decreases are seen throughout the Tahoe/Suburban and Yukon/Yukon XL lineup. Because there are so many variants, weÂ’re going to just lay them out below for you. 5.3-liter V8 2021 Tahoe/Yukon 2WD: 16/20/18 2021 Tahoe/Yukon 4WD: 16/20/18 2021 Suburban/Yukon XL 2WD: 16/20/18 2021 Suburban/Yukon XL 4WD: 15/19/17 6.2-liter V8 2021 Tahoe/Yukon 2WD: 15/20/17 2021 Tahoe/Yukon 4WD: 14/19/16 2021 Suburban/Yukon XL 2WD: 15/20/17 2021 Suburban/Yukon XL 4WD: 14/19/16 As you can see, there isnÂ’t a whole lot of difference between two-wheel drive and four-wheel drive options. You can eke out an extra mpg here and there, but itÂ’s a penalty weÂ’d be happy to live with to have four-wheel traction. The biggest loser in all of this is highway mpg. Chevy has made the trucks bigger and added weight with the independent rear suspension, causing a decrease in fuel economy. For example, a 2020 Tahoe with the 6.2-liter V8 and four-wheel drive is rated at 14/22/17. The 2021 truck drops 3 mpg on the highway and 1 mpg in the combined rating. There are improvements to be found, though. A 2020 Suburban with the 5.3-liter V8 and four-wheel drive is rated 14/21/16. Fuel economy in the city goes up 1 mpg, but you lose 2 mpg on the highway and 1 mpg in the combined rating. ThereÂ’s a bit of give and take here, but at least a slight increase in city mpg has accompanied the greater loss in highway fuel economy. 2021-chevy-tahoe-chicago-01 View 12 Photos As for towing, the Tahoe/Yukon with the 5.3-liter V8 and two-wheel drive has a new 7,900-pound capacity, and the four-wheel drive model is rated at 7,700 pounds. Respectively, those are the best figures youÂ’ll get with the standard towing capacity. Opt for the maximum towing package, and the Tahoe/Yukon capacities go up to 8,400 pounds (two-wheel drive) and 8,200 pounds (four-wheel drive). The numbers all take slight cuts when you go for the 6.2-liter V8. Both the Suburban and Yukon XL offer similar or identical towing figures as their shorter counterparts do.

Watch the 2022 GMC Hummer EV launch using its Watts to Freedom mode

It’s nearly the July Fourth weekend, and GM is celebrating Independence Day a little earlier than most. The celebration comes in the form of a GMC Hummer EV demonstrating Watts to Freedom, or WTF, mode for us on video. You can watch it at the top of this post, but the idea is rather simple. ItÂ’s just a video of a Hummer development vehicle accelerating as quickly as it can from 0-60 mph and beyond. GMC claims its 1,000-horsepower electric Hummer is capable of hitting the 0-60 mph mark in “approximately 3 seconds,” which is borderline terrifying for how large of a vehicle it is. The super-quick time is possible when using the Watts to Freedom launch control mode, which “channels the propulsion systemÂ’s tremendous power into acceleration bursts.” The truck will still be plenty fast when accelerating normally, but WTF mode is what you should use to unlock its full potential. GMCÂ’s video shows us the graphics it uses in the digital cluster to signal Watts to Freedom is activated, and the whole sequence looks like it leans on U.S. military themes for both design and phrasing. For example, GMC lets you know that Watts to Freedom is ready via an “Armed” message in the cluster.  The 2022 GMC HUMMER EV is a first-of-its kind supertruck develop View 40 Photos Instead of a rumbling exhaust and screeching tires, the Hummer appears to silently launch with all four tires grabbing on and catapulting the truck away. It looks quick as it throws all of the weight rearward into an accelerative squat. And in case you missed it, thatÂ’s a lot of weight — GMC says itÂ’ll tip the scale at 9,046 pounds. GMC has previously said that production will begin in late 2021, and this video continues to confirm that timeframe with a note saying “initial availability Fall 2021.” Do keep in mind that only the sold-out Launch Edition is coming at that time. Other cheaper variants will follow in the years to come. Related video: This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings.

GM recalls Colorado, Canyon, and Malibu for airbag problem

The Basics: General Motors will recall and issue a stop sale on 1,740 total examples of the 2016 Chevrolet Colorado, Malibu, and GMC Canyon. This includes 1,579 units in the US and 161 in Canada. The Problem: The second stage of the driver front airbag inflator might not be present. If this happens, the airbag won't fill as quickly as it should in a high-speed crash, which could increase the risk of injury, according to Reuters. This is not related in any way to Takata's inflator problems, and these parts come from a different supplier. Injuries/Deaths: None reported. The Fix: GM will replace the vehicles' airbag assemblies. If You Own One: GM spokesperson Tom Wilkinson told Autoblog he wasn't specifically sure when recall repairs would begin but said it would be "shortly." He expects the fixes to happen "quickly" because of the small number of affected vehicles, and many of them are either in transport or already in dealer stock. More Information: GM recalled the 2015 Canyon and Colorado in 2014 for a completely separate airbag issue. In that case, a manufacturing error improperly wired the connectors. Related Video: GM Statement GM is recalling 1,579 MY 2016 Chevrolet Colorado, GMC Canyon and Chevrolet Malibu vehicles in the United States and 161 in Canada to replace driver-side front airbags. The second stage of the airbag may not deploy properly in certain high-speed crashes. During a routine quality inspection, it was determined that a component required for a second-stage/high-output deployment was not loaded during the inflator build. Dealers will replace the driver-side front airbag assembly. There have been no reports of crashes or injuries related to this issue. This issue is unrelated to the ongoing Takata recalls.
