2015 Sierra All Terrain HD looks ready to hit heavy-duty trails

GMC is getting its heavy-duty trucks ready for the mud this summer with its All Terrain package for the Sierra 2500HD and 3500HD. Meant to blend style, tech and ruggedness, the pack includes a lot of extra chrome outside and an off-road package underneath.
The 2015 Sierra All Terrain HD trucks naturally come standard with four-wheel drive with an electronically controlled transfer case to handle things in the dirt. The Z71 off-road package is also standard, which includes Rancho twin-tube shocks, hill descent control and a skid plate. To add some style when off the beaten path, the pack includes chrome trim on the mirror caps, lower bumper and grille surround, plus LEDs around the headlights and 18-inch wheels (20-inchers are optional on the 2500HD). The 3500HD also gets chrome, adjustable outside camper mirrors. The interior receives a technology upgrade thanks to the standard rearview camera and IntelliLink infotainment that can act as a Wi-Fi hotspot through OnStar 4G LTE, read text messages and includes Siri Eyes Free for iPhone users.
The All Terrain package goes on sale on both trucks this summer and is offered on either the SLE or SLT trim levels in double cab and crew cab models. The standard engine is the 6.0-liter V8 with 360 horsepower and 380 pound-feet of torque, but the Duramax 6.6-liter, diesel V8 with 397 hp and 765 lb-ft is also available. The gas engine is mated to a Hydra-matic six-speed automatic, and the diesel uses an Allison six-speed automatic. Scroll down to read the full announcement about these heavy-duty off-roaders.

Editors’ Picks October 2022 | Electric trucks and some excellent SUVs

This month sees a bevy of totally new or totally redesigned cars gain Editors’ Pick status. Important EVs like the F-150 Lightning and GMC Hummer EV quickly jump into the list, and they do so with authority, as all our editors love these trucks. The Range Rover is always a superb experience, and this generation proves to be no different. Plus, the new generation of Kia Sportage continues to surprise and impress. In case you missed our previous Editors' Picks posts, hereÂ’s a quick refresher on whatÂ’s going on here. We rate all the new cars we drive with a 1-10 score. Cars that are exemplary in their respective segments get EditorsÂ’ Pick status. Those are the ones weÂ’d recommend to our friends, family and anybody whoÂ’s curious and asks the question. The list that youÂ’ll find below consists of every car we rated in October that earned an EditorsÂ’ Pick. 2022 GMC Hummer EV The Four-Wheel-Steer system lets the 2022 GMC HUMMER EV Pickup m View 17 Photos Quick take: The Hummer amazes as an electric supertruck with its wild acceleration, incredible off-road capability, luxuriousness and epic utility. It's far from a "green" eco-friendly vehicle, but that's not the point of this technological powerhouse. Score: 8.5 What it competes with: Rivian R1T, Ford F-150 Raptor R, Ram 1500 TRX Pros: Stupid quick, tons of tech, off-road capability in spades Cons: Not efficient, annoying in tight spaces, price From the editors: Road Test Editor Zac Palmer — "I don't think I've driven a more ridiculous vehicle this year, but that's sort of the point with the Hummer. There's a great argument against this sort of EV in that it doesn't live up to being an efficient and planet-friendly vehicle, but hey, that's not the point. The Hummer EV is a supertruck and wild technological masterpiece for off-roading in the same way that a mid-engine supercar is to track performance. It's not meant to be the EV everybody drives to work and back (mostly because few can afford it), but it serves as a line in the sand of what can be done with electric off-road trucks. This pickup rules, and if you can afford one, you're going to love it." Senior Editor, Green John Beltz Snyder — "This Hummer revival is a showcase of technology and capability on the part of GM, making it an absolute blast to drive and a joy to use.

GM 6.2L V8 claims most powerful light-duty truck engine title

General Motors has officially captured the horsepower crown for mainstream pickup trucks with its 6.2-liter V8. The big mill, available in both the Chevrolet Silverado and GMC Sierra, comes to market with 420 horsepower and 460 pound-feet of torque, handily outdoing its two cross-town competitors, Ram (5.7-liter V8, 395 ponies and 407 lb-ft) and Ford (6.2-liter V8, 411 hp and 434 lb-ft).
The new GM 6.2 will take a bit of an investment, though. Those that want the extra thrust will need to go with either the LTZ or High Country trims from the Chevy, or the SLT and Denali trims from GMC, which are the two highest trim levels for the respective vehicles. Trim levels aside, if you're in the business of towing, GM has you covered. Optioned with the 6.2-liter V8 and the Max Trailering Package, owners will be able to pull 12,000 pounds, a hugely impressive figure.
We still aren't certain as to what sort of economy the new engine will get, but it'll probably be a bad bet for the fuel conscious. As for availability, expect to see the 6.2-liter trucks in showrooms later in the fall.
