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.

2014 Chevy Silverado, GMC Sierra first pickups to ace updated NHTSA tests [w/video]

General Motors has just become the first pickup truck manufacturer to receive five-star overall vehicle scores in the National Highway Traffic Safety Administration's New Car Assessment Program. The updated safety standards, which went into effect in 2011, are more strenuous than the previous NHTSA curriculum and involve collecting both more and more substantial data, reflecting the improved safety inherent in newer vehicles. This feat is made more impressive by the fact that both Ford and Ram have released brand-new trucks since the new testing went into effect - GM's victory is no technicality.
The rating only applies to the redesigned, light-duty Silverado, Sierra and their upmarket variants, High Country and Denali, respectively, while only Crew Cab variants were tested. Considering that the four-door body style will make up 60 percent of GM's light-duty truck sales, the exclusion of the other variants seems reasonable.
This news is sure to be yet another feather in GM's pickup-oriented cap. Be sure to scroll down for video of the crash testing, as well as the full press release from General Motors.
