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.

Supercharged 2015 GMC Yukon Denali sounds evil, runs 0-60 in 4.5 seconds

Speeding along in a sports car is undoubtedly a ton of fun, but some owners need the ability to carry a lot of people and their stuff and don't want to sacrifice the ability to put the power down. The tuners over at Hennessey have that demographic covered with their growling, supercharged power kits for the GMC Yukon Denali. The upgrades come in three forms for the SUV's 6.2-liter V8: HPE550 with 557 horsepower, HPE600 with 605 hp and HPE650 with 665 hp. This video showcases the full-bore version, and this Denali can definitely hustle in a straight line. The power bump comes courtesy of a 2.9-liter supercharger, intercooler and high-flow cylinder heads to add over 200 horsepower compared to stock, and the final result is a bellowing SUV that rears up off he line to throw the driver back into the seat. The sprint to 60 miles per hour lasts just 4.5 seconds. Check out this hasty hauler in action in the video above.

2019 GMC Sierra 1500 spied in base trim level

When the 2019 GMC Sierra 1500 half-ton pickup was revealed, it was shown in the ultra-deluxe Denali trim with its carbon fiber bed and trick tailgate. And thanks to spy shots, we've been able to see the more modest SLE a few months ago. Now we get to see it in the most plain work truck iteration thanks to the above photos. This Sierra doesn't appear to have any trim designation. The SLE we saw had a badge in the lower left of the tailgate, but none appear on this except "Sierra." This fits with the current trim scheme for the Sierra, which calls the basic one simply by its model name. In addition to less badging, this Sierra ditches most of the chrome found on other trim levels. The grille insert is plain black plastic, as are the fender vents, door handles and window trim. There aren't engine badges, either. Currently the only engines announced for the Sierra are the gasoline 5.3-liter and 6.2-liter V8s and the diesel 3.0-liter six-cylinder. We would assume from the basic nature of this truck that it has the 5.3-liter V8. Nothing has been announced about a gasoline V6 for the new generation of Sierra and Silverado pickup trucks, despite a 4.3-liter V6 still being available on the 2018 model. Also, since this is a base Sierra, the bed is all steel and the tailgate is one big panel. Pricing still hasn't been revealed for the Sierra. But this and the other Sierra trims will go on sale in the fall, with pricing likely announced sometime in-between. Related Video: This content is hosted by a third party.
