GMC introduces off-road performance package for Sierra AT4

GMC is giving its off-road-focused Sierra AT4 pickup even more performance with some factory-installed upgrades. The package is called the AT4 Off-Road Performance Package. With it you'll get the 6.2-liter V8 engine upgrade, cat-back performance exhaust system, performance air intake and 18-inch aluminum wheels shod in Goodyear Wrangler DuraTrac tires. The upgraded performance comes in the form of extra power. Thanks to the bolt-ons, you gain 15 horsepower and 9 pound-feet of torque over the 6.2-liter in stock form. This increases output to 435 horsepower and 469 pound-feet of torque — not too shabby. This package is priced at $4,940, and available for order now. That's a hefty price for what amounts to some minimal bolt-on modifications you could easily do yourself. However, buying it through GM means you get to keep your warranty in place. The Sierra AT4 already has more off-road features than a normal Sierra 1500. You're getting a two-inch lift, four-wheel drive with two-speed transfer case, locking rear differentials, skid plates, Rancho off-road shocks and hill descent control. Both the wheels and tires are available as options already, but this package just bunches related stuff together. It'll be up to you to decide if an exhaust and intake are worth the extra dough.

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.

GMC Syclone spools up a storm on Jay Leno's Garage

A storm was brewing on American roads in the early 1990s. That's when Detroit's automakers were producing some of the hottest performance trucks ever devised – models like the Ford Lightning, GMC Typhoon, and its flyweight pickup sibling, the GMC Syclone. Jay Leno just happens to have one of the latter in his garage, and took it out to showcase in this latest video segment. The Syclone was an exercise in absurdity, and could not only trounce any other pickup on the road, it could outrun anything else GM made and just about anything else on the road – beating Ferraris and Porsches off the line. In a pickup, for crying out loud. The kicker is that its engine wasn't such a monster, either: under the hood sat a 4.3-liter turbocharged V6 pumping out what would seem by today's standards to be an adequate 280 horsepower and 350 pound-feet of torque. Even the smaller of the EcoBoost V6s available in today's Ford F-150 produces more than that. But in a lightweight, compact pickup, those figures were enough to propel the Syclone to 60 in 4.3 seconds and run the quarter-mile in 13.6 seconds. Long before the dune-jumping Ford F-150 SVT Raptor or even the Viper-powered Dodge Ram SRT-10, GM made fewer than 3,000 Syclones based on the compact Sonoma (sister to the Chevy S-10) and another 4,700 of the Typhoon, which was mechanically similar but more practical (albeit heavier) wagon bodywork from the Jimmy. But as Jay aptly points out, the Syclone was the one you wanted. Scope it out in the ten-minute video clip above.
