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 details continue to dribble out

PickupTrucks.com has gotten its hands on a few more details concerning the 2014 Chevrolet Silverado and the 2014 GMC Sierra. General Motors held a conference call on the two trucks, allowing Jeff Luke, executive chief engineer for both, to answer a few questions. Luke said truck buyers are largely concerned with power and fuel economy, and as such, GM will continue to explore new methods of providing both. That may translate into any number of drivetrain permutations, including light-duty diesel engines, eight-speed transmissions or even a twin-turbocharged V6.
What's more, both the 2014 Silverado and its GMC twin will boast a tow rating of 11,500 pounds, but only when equipped with a max-trailering package. Without that special package, the rating drops to 10,200 lbs for regular cabs and 9,700 lbs for crew cabs. Buyers will no longer be able to opt for a 4.10 gear ratio.
We're also excited to hear that GM plans on making the Z71 package into something more than just a few a stickers. While Luke didn't go into details, PickupTrucks.com says "it will get significant improvements in the future." Head over to the site for a quick rundown of the call's highlights.

2017 GMC Sierra 2500HD All Terrain X eyes Ram Power Wagon

If where you're going, you don't need roads, you're spoiled for choice by American automakers. Ford has the F-150 Raptor, Jeep the iconic Wrangler, and Ram offers Power Wagon. And that's just the tip of the factory off-road iceberg. General Motors is getting in on the off-roading action with the Canyon and Sierra 1500 All Terrain X. Now, the automaker is adding another notch on its belt with the Sierra 2500HD All Terrain X. On the outside, GMC continues to the all-black trend as the rest of its off-roading-oriented lineup, which includes 18-inch aluminum wheels finished in black, a bespoke grille surround, black sport bar that's mounted in the truck's bed, and four-inch side steps in black. The All Terrain X will only be offered in two colors – Black Onyx and Summer White. Those looking for more off-roading capabilities and tack the Z71 off-road suspension package as an option on the All Terrain X, adding performance Rancho shocks, Hill Descent Control, and a shield for the underbody transfer case. Two engine choices lie under this crew cab pickup's massive hood - the 6.0-liter gas V8 or the all-new Duramax 6.6-liter turbo-diesel V8. The gasoline-powered V8 continues to make 360 horsepower and 380 pound-feet of torque, while the new Duramax turbo-diesel generates 445 horsepower and 910 pound-feet of torque. While the All Terrain X may not have the same murderous look as the Ram Power Wagon, it makes off-roading a luxurious affair. And it's blacked out. The 2500HD power wagon will be on sale early next year, with a pricing announcement coming sometime in the next few months.
