2024 GMC Canyon AT4X AEV Edition pushes the limits even higher

The GMC Canyon AT4X is already a formidable off-road pickup truck, but now it’s getting even more capable with the addition of the 2024 GMC Canyon AT4X AEV Edition. If youÂ’re familiar with the Chevrolet Colorado ZR2 Bison, then by proxy youÂ’re familiar with GMCÂ’s version of it already. Like the bow-tie version of the pickup, the AT4X AEV Edition is lifted an additional 1.5 inches beyond the regular AT4X, giving it 12.2 inches of ground clearance, which is identical to the ZR2 Bison. You also get to work with a 38.2-degree approach, 26.0-degree departure, and 26.9-degree breakover angle. ItÂ’s fitted with AEV beadlock wheels wrapping 35-inch Goodyear Wrangler Territory mud-terrrain tires and uses hot-stamped boron steel skid plates for the radiator, steering gear, transmission, transfer case, fuel tank and rear differential. Appearance-wise, the AEV Edition sports a new front fascia with integrated fog lights and larger fender flares that facilitate the bigger tires. It uses AEV stamped-steel front and rear bumpers that include heavy-duty recover points, and the front bumper is compatible with a winch. The rear bumper (below) is particularly clever, as it has easily removable plastic corners that can be replaced with 10 millimeter-thick steel skid plates for a little extra protection on the trail. YouÂ’ll find an AEV in-bed mount for the spare tire, too, as the big 35-inch tire doesnÂ’t fit in the usual under-bed storage spot. GMC wasnÂ’t ready to provide hard numbers for payload or towing, but expect the Canyon AT4XÂ’s specs to go down in a similar manner as the ZR2 Bison that lost 230 pounds of payload capacity and 500 pounds of towing. And yes, the AEV Edition retains the AT4XÂ’s high-output four-cylidner that produces 310 horsepower and 430 pound-feet of torque. You get all the other AT4X goodies, too, including things like the Multimatic spool valve shocks and electronic-locking front and rear differentials. It also gets the sweet off-road launch control system that initially debuted on the Bison that can adjust power in real-time based on the traction available off-road. On the inside, the AEV Edition adds three standard auxiliary switches that you can hook up off-road or overlanding accessories to. The truck is also fitted with AEV-embroidered headrests and AEV all-weather floor liners. Pricing for the AT4X AEV Edition isnÂ’t available quite yet, but GMC says itÂ’s expected to be available for customer orders later this year.

2024 GMC Sierra 1500 AT4X makes Duramax diesel standard

Changes are afoot for the 2024 GMC Sierra 1500 lineup. The one ringing the biggest bells for the off-roading crowd is the engine swap headed to the AT4X trim. Right now, if you want an AT4X you've got Hobson's choice of engines: The 6.2-liter EcoTec V8 with 420 horsepower and 460 pound-feet of torque. Next year, the 3.0-liter Duramax turbodiesel inline-six that's standard equipment on the AT4 and Denali Ultimate trims becomes the standard engine on the AT4X. The oil-burner makes 305 hp and 495 lb-ft., sent through the same ten-speed automatic the 6.2 V8 is yoked to. GM said around 20% of buyers have checked the Duramax box when buying a Sierra 1500 since the automaker released the upgraded engine for the 2023 model year — it's also offered on the SLE, Elevation, SLT, and Denali trims. The percentage should grow thanks to the diesel's low-speed grunt being one of the best "force multipliers" when traipsing over and through particularly challenging corners of the woods. The 6.2-liter will take the exhaust note crown over the diesel after the introduction of an active exhaust system with a Sport mode exclusively for the 6.2. Assuming no more changes to engine lineups before the 2024 Sierra arrives, the SLT, AT4, Denali, Denali Ultimate, and AT4X will have access to the active exhaust option.   GM Authority says the Duramax is getting another maximal friend in 2024, too. The 2.7-liter Turbo High-Output four-cylinder makes 310 hp and 430 lb-ft and is standard equipment on the entry-level Pro trim. the SLE, and Elevation trims will be renamed "TurboMax," which sounds like an Autobot, and that's not a bad thing. GM applied to trademark the name in January. The new moniker is headed to the Chevrolet Silverado as well, and we'd bet on exterior badging to let the world know.  Elsewhere around the Sierra, there will be two new exterior colors, Downpour Metallic and Thunderstorm Gray, mixable and matchable with two new aluminum wheel designs. And between those wheels, power retractable steps will be available for the Denali, Denali Ultimate, AT4 and AT4X trims. We'll be waiting to see how the steps differ from the GMC MultiPro Power Steps available now for $1,195.  Related video: This content is hosted by a third party.

GM 6.2L EcoTec V8 rated at 21 mpg by the EPA

General Motors is already laying claim to best-in-class power for its new 6.2-liter V8 that will be offered in the 2014 Chevy Silverado and GMC Sierra this fall, and now it has released fuel economy numbers for the big engine. Available as an option on the Silverado LTZ and High Country (shown above) models as well as the the Sierra SLT and Denali trims, the 6.2L EcoTec3 V8 will return 15 miles per gallon in the city and 21 mpg on the highway on rear-wheel-drive trucks; these numbers drop by one mpg each on four-wheel-drive models.
These estimates are in addition to the engine's 420 horsepower, 460 pound-feet of torque and max trailering capacity of 12,000 pounds, and considering all that power it's not terribly far away from the fuel economy of GM's equally new 4.3-liter V6 and its rating of 18 mpg city and 24 mpg highway. This announcement comes just days after a report indicated that GM is unable to keep up with the demand of the 5.3-liter V8 in the fullsize Chevy and GMC trucks due to supplier issues. GM's official press release for the 6.2-liter V8's fuel economy is posted below.
