2023 GMC Sierra AT4X new AEV Edition's spirit animal is the Bison

GMC's newly redesigned 2023 Sierra is getting some equipment that might sound familiar to fans of the Chevrolet Colorado ZR2 formula that inspired it. Don't call it a "Bison," but the new Sierra AT4X AEV (American Expedition Vehicles) Edition sounds an awful lot like everybody's favorite bovine-themed midsize off-road pickup, and GMC says it will be its most off-road capable factory Sierra 1500 ever. If you're not familiar with the AT4X formula, it's already pretty robust. The GMC twin to the new Silverado ZR2 boasts Multimatic DSSV spool-valve dampers, improved ground clearance and approach/departure/breakover angles compared to the "standard" AT4, plus front and rear electronic locking differentials. The AEV Edition looks to the margins for additional improvement.  "The Sierra 1500 AT4X is an incredibly formidable platform when it comes to on- and off-road performance and capability,” said AEV CEO & founder Dave Harriton. “We took our signature approach to help elevate this truckÂ’s inherent off-road capability to the next level. We are confident customers will love the result." The standard AT4X already offers plenty of ground clearance (10.8 inches) and an approach angle of 25.5 degrees, departure angle of 23 degrees and breakover angle of 22.7 degrees. The AEV Edition bumps the ground clearance to 11.2 inches and its AEV-sourced stamped steel bumpers improve the approach angle to 32.5 degrees, departure angle to 23.4 degrees (compared to 23 degrees) and the breakover angle improves to 23 degrees.  "Our customers want an uncompromising combination of on-road technology and off-road capability," GMC boss Duncan Aldred said in the company's announcement. "Leveraging GMCÂ’s unwavering dedication to providing premium trucks and AEVÂ’s expertise in engineering and integrating performance-driven parts and accessories, this truck provides extreme capability, technology and comfort." The AEV Edition will ride on 33" mud-terrain tires wrapped around unique 18-inch AEV "Salta" wheels finished in gloss black. The front end was restyled to accommodate the AEV Edition's wheel and tire package (it was too big for the existing wheel wells, apparently) and front bumper.

GM considering new powertrain options for large SUVs

Aside from the new General Motors offerings, there's not a whole lot of action going on in the fullsize SUV segment. That doesn't seem to be stopping GM from pushing the envelope in the market as Automotive News is reporting that the automaker is looking to introduce some new powertrain options into the Chevy Tahoe (and Suburban), GMC Yukon (and Yukon XL) and the Cadillac Escalade - all have been redesigned for the 2015 model year.
Now, we already know that GM and Ford are collaborating on nine- and ten-speed transmissions for a broad range of applications (including the big SUVs), but this new report says that GM is also considering other options as a way to one-up the competition and, of course, to optimize fuel economy. AN quotes Jeff Luke, executive chief engineer for GM trucks, as saying that "interesting powertrain technologies" are coming including a return of a hybrid SUV and possibly even a diesel engine. Although it sounds like the latter could come down to how customers respond to the 2014 Jeep Grand Cherokee EcoDiesel.

2018 GMC Sierra Denali can help you tow without breaking a sweat

Towing a trailer once meant that only those who possessed certain knowledge would be able to go fishing, tow a race car or pull a camper safely. For me, it took four long years of practice working a job behind the wheel of a jacked-up Ford F-250, hauling tons upon tons of mowing equipment for my local parks department, to become proficient. Just how far things have come since then became evident after a recent trip to Utah with GMC, in which we used the half-ton Sierra Denali to tow a set of Polaris side-by-sides through the state. Modern safety technology and a suite of electronic aids make towing simple enough that anyone with a driver's license and something to haul can do it. This revelation came behind the leather-wrapped and heated steering wheel of GMC's outgoing 2018 Sierra Denali. Sitting in the plush, heated and cooled captain's chair, I could barely feel the 6,000 pounds I was towing behind me. Even GMC's smallest full-size truck engine, a 5.3-liter V8 generating 355 horsepower and 383 lb-ft of torque, felt like overkill for what used to amount to a heavy load. With Utah's pristine landscape, the plush confines of the cabin and the uneventful nature of modern towing, mile after mile just streamed by at highway speeds without incident (or excitement). When we finally reached our destination a few hours later, one of GMC's representatives who had chosen to sit in the rear of the cab asked me what I thought about the drive. I pondered for a few minutes and answered with this: "Modern pickup trucks have removed nearly every skill-based variable once associated with towing. I could drive this truck and trailer confidently with just one finger." Consider the near overabundance of towing-assistance systems in the GMC Sierra Denali that I piloted through Utah. Let's start with the most basic of towing skills — something that's now been relegated to the annals of history: reversing a pickup to meet the trailer's hitch. Once upon a time, this required knowing a truck's dimensions and understanding proximity, as well as having a keen eye, a steady foot for both the gas and the brake and the patience to get it right. Now, though, pickups such as the Sierra Denali offer customers a trailer reverse camera system that helps the driver align truck to hitch with pinpoint accuracy.
