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.

GMC's Denali offerings are going great guns

The Denali trim that GMC uses to denote its top-of-the-line vehicles was introduced back in 1999, partly as a way to challenge the recently introduced Lincoln Navigator. Fifteen years later, and with GMC the tenth-largest US automotive brand by itself Denali has become a sub-brand that keeps the cash registers ringing at the Renaissance Center HQ. While GMC increased sales by 9 percent in 2013, TheDetroitBureau.com reports that that Denali sales rose by 20 percent.
There are currently five Denali models in the GMC line, with the Denali trim available on all but its commercial vans. In 2010, when the now-discontinued Yukon XL Hybrid was also on sale, GMC sold 32,886 units of its top trim. Last year, that number had increased to 75,558, with almost no help from traditional marketing spends. Go to YouTube and search for "GMC Denali commercials" - the few actual commercial results are from years ago. GMC marketing director Roger McCormack tells TheDetroitBureau.com, "It's largely all been organic."
As sales have grown, so has the tide of money GMC rakes in from the additional luxury features on Denali models. The 2015 Chevrolet Tahoe starts at $44,600, yet its 2014 Yukon Denali doppelganger starts at $58,320, pricing that includes additional features like the larger 6.2-liter V8, nicer interior, head-up display and magnetic ride control suspension. The Yukon XL Denali starts at $60,965, but the article says the "average customer" likely to spend "up and above $70,000" to take one home. How does that happen? On a top-trim Tahoe LTZ, the top-tier wheel option is a set of 20-inch chrome wheels for $400; on the 'base' Yukon Denali you can swap for a set of 22-inch chrome alloys for $2,995. Add it up, and an analyst at AutoTrends Consulting said that kind of margin "epitomizes the concept of obscene profitability." We say when it comes to Denali, GMC appears to stand for "Grabbing More Cash."

New Takata problem results in recall of 414 GM vehicles

An airbag-inflator rupture discovered by Takata during testing has resulted in a new recall affecting 414 vehicles from General Motors, including 395 of them in the US. This latest campaign covers 2015 model-year examples of the Buick LaCrosse, Cadillac XTS, Chevrolet Camaro, Equinox, Malibu, and GMC Terrain. There are no reported breaks in any of these vehicles on the road, and the company estimates only one percent of them actually have the faulty parts. According to documents submitted to the National Highway Traffic Safety Administration (as a PDF), one side-airbag inflator failed a cold test at -40 Fahrenheit "releasing high pressure gas and propelling the separated components apart." The supplier told GM about the failure the next day. In these vehicles, the safety device might not only burst but the bag could inflate incorrectly, as well. GM and Takata say that a cause is not yet known, but they are "conducting an investigation." GM will begin notifying affected owners via overnight mail on Oct. 19. Dealers will replace the side airbag modules on all of the affected vehicles with new components outside of the suspect lot. All of the removed parts will also be collected for further study. Takata's faulty front airbag inflators have resulted in a serious scandal for the supplier. Initial figures indicated 34 million US vehicles are need of repair, though more recent figures have knocked that down to 23.4 million bad parts in 19.2 million automobiles. GM was already among the dozen automakers with models to fix, and some of its pickups were affected, along with the Saab 9-2X and Pontiac Vibe. GM Statement: General Motors is recalling 395 cars and crossovers in the U.S. because one of the front seat side air bags inflators may be defective. In the event of a deployment, the air bag's inflator may rupture and the air bag may not properly inflate. The rupture could cause metal fragments to strike the vehicle occupants, potentially resulting in serious injury or death. GM is unaware of any incidents involving vehicles with these components, which were part of a lot in which one inflator failed acceptance testing at the supplier. Dealers will replace the side air bag module or modules in affected vehicles. Including Canada, Mexico and exports, the total population of the recall is 414, GM estimates 1 percent of the recalled vehicles may have the defect.
