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.

GMC Canyon AT4 OVRLANDX concept previews potential Bison-like model

GMC is signaling a move into serious off-road territory with this Canyon AT4 OVRLANDX concept. As its name suggest, this one-off was put together as a demonstration of what an overland-style GMC midsizer could potentially look like, but a glance beneath the surface reveals the bones of what we expect to be the forthcoming Canyon AT4X.  While "AT4" has been trickling down through the GMC lineup for the past few model years, AT4X kicks the basic off-road formula up a notch, a la Chevrolet's Colorado ZR2, which gains extra underbody protection, locking front and rear differentials and Multimatic's phenomenal DSSV dampers.  GMC Canyon AT4 OVRLANDX Off-Road Concept View 23 Photos OVRLANDX takes that to the next level, borrowing (and building upon) cues from the even-more-rugged ZR2 Bison, including rocker panel guards, cast-iron control arms, a custom front bumper with an integrated winch, built-in front recovery points, wheel arch trim with integrated LED task lighting, and guy lines for protecting the windshield from low-hanging branches. The custom rear bumper is even from American Expedition Vehicles (AEV), with whom Chevy partnered to produce the Bison's unique exterior bits. Does that seem like a wink and nod to you? “We wanted to showcase GMC Canyon with this concept and punctuate GMCÂ’s commitment to premium, off-road capable vehicles,” said Buick & GMC Global Vice President Duncan Aldred. "Consumer reaction to this conceptÂ’s design will help us further serve the growing market of buyers leading authentic outdoor lifestyles." This content is hosted by a third party.

In a way, the roof-mounted tent, awning, cooler and kitchenette are just there to disguise the fact that GMC will likely build a production pickup with much these same specs when the new model debuts for the 2023 or 2024 model year – or perhaps even sooner. While this concept is built around GM's existing 3.6-liter V6 powertrain, the redesigned Canyon is expected to be offered with just one engine: a 2.7-liter turbocharged four-cylinder lifted from the Silverado and Sierra pickups.  Rumors have pointed to a GMC variant of the Colorado ZR2 since the midsize pickup adopted the AT4 branding for its off-road variant.

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.
