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.

GM readying aluminum-body fullsize pickups

Ford's extensive use of aluminum in its 2015 F-150 is a big deal. A really big deal. Big enough, in fact, that General Motors is reportedly changing its fullsize pickup strategy. According to The Wall Street Journal, The General has locked in partnerships with Alcoa Inc. and Novelis Inc. - companies that will supply aluminum for the next-generation Chevrolet Silverado and GMC Sierra trucks.
"Ford's introduction of the 2015 F-150 pickup truck was a game changer, and it's the first, not the last, conversion of this type," Novelis spokesperson Charles Belbin told the Journal. The switch to aluminum has allowed Ford to shave roughly 700 pounds off its fullsize truck's curb weight. And while official mileage ratings have not been announced, the weight loss should go a long way for improving efficiency, especially when combined other efficiency-minded improvements including better aerodynamics and new, turbocharged V6 engines.
Of course, aluminum-bodied cars are nothing new. But extensive use of aluminum in a major, best-selling product like the Ford F-150 is expected to kick off widespread use of this weight-saving material as availability rises and cost decreases. The WSJ reports that GM had originally explored the idea of moving to aluminum pickups back in 2008, but abandoned the idea due to cost concerns amid economic woes.

GM opens military discount to 21M veterans and their spouses

May marks the start of National Military Appreciation Month, and General Motors is getting into the spirit by expanding its military discount program to, well, just about everyone. That includes a total of 21 million military veterans and their spouses, along with the current slate of active duty, reserve, and National Guard members. The discount can slash thousands of dollars off the price of a new Buick, Chevrolet, or GMC vehicles, with Automotive News listing an $1,100 discount on the top gas-powered version of the Malibu, the Premiere. Those that want a bit more spice can get $1,700 off the price of a last-generation 2015 Camaro SS, while truck buyers will enjoy $3,000 off the Chevy Silverado All Star. That's just a start, though, since the military discount can be paired with other GM incentives. The discount doesn't apply to everything, though. Some are understandable – none of Cadillac's vehicles are included in the deal, nor is the Corvette Z06. You'll also be unable to apply the discount to a range of base-level trims, like the Chevy Cruze or Equinox L, the base Colorado, or the entry level GMC Acadia, Canyon, and Terrain. A full list is available at GM's dedicated military discount website. GM's expanded discount plan runs from today through May 31.
