GMC boss wants a Jeep Wrangler rival

Challengers come and challengers go, but the Jeep Wrangler continues to push forward even after vehicles like the Toyota FJ Cruiser and the entire Hummer brand have been shut down. Now GMC reportedly wants to take a stab at the quintessential Jeep, as well.
The news comes directly from Buick-GMC vice president Duncan Aldred, speaking with our compatriots over at Edmunds. Although Aldred said there are no plans currently on the table to expand GMC's lineup beyond the current range, "there is plenty of room everywhere in the hierarchy."
That could include a rival to the Wrangler, as well as a flagship luxury SUV positioned above the current Yukon Denali (pictured above). Just when (or for that matter, if) such models might come into fruition remains a big question mark, but it's certainly interesting to see what GM's dedicated truck brand has on the drawing board.

2017 GMC Canyon finally goes Denali

You knew this was coming and perhaps you've been waiting for it: the GMC Canyon dressed up in Denali trim. Even though we're getting to see it before its reveal at the LA Auto Show, you'll have to wait roughly one more year to take delivery since it doesn't go on sale until "late 2016." You can spec the trim on the crew cab models with either the 3.6-liter gasoline V6 or the 2.8-liter diesel engine. You know the formula, and it works well on the Canyon. There's a chrome grille, chrome trim around the foglights, chrome side steps, one polished exhaust tip, a spray-in bedliner, and 20-inch ultra-bright wheels. You can get the rest of the truck done up in one of six colors, two fewer than are available for non-Denali trims. The inside comes in Jet Black only, with heated and ventilated front seats, Denali badging, and a unique instrument panel. Check out the press release below for more info, we'll have live images from LA soon. GMC Introduces 2017 Canyon Denali Exclusive design cues, content elevate industry's first premium midsize truck DETROIT, Tuesday, Nov. 17, 2015 – Denali is the ultimate expression of GMC's professional grade style, luxury and capability – and it is coming to the Canyon midsize truck. The 2017 Canyon Denali is being introduced today, ahead of its public debut at the Los Angeles Auto Show. It goes on sale in late 2016. "Canyon is the segment's first and only premium midsize truck, offering unparalleled capability and efficiency matched with maneuverability and refinement," said Duncan Aldred, vice president of GMC Sales and Marketing. "The all-new Canyon Denali builds on that award-winning combination with the distinctive styling, luxurious interior and elevated content that has defined the Denali nameplate since its introduction nearly 17 years ago." Like all Denali models, the new Canyon Denali is distinguished with a unique chrome grille and unique wheels – 20-inch ultra-bright-machined aluminum wheels with painted accents. Exterior cues include chrome fog lamp bezels, five-inch-diameter rectangular chrome assist steps, a polished exhaust tip and a standard spray-in bed liner. The Canyon Denali will be offered in six exterior colors. Inside, a Jet Black interior features Mulan leather-appointed seats with perforated, heated-and-ventilated front seats – exclusive content in the Canyon lineup – along with unique instrument panel and console trim; and Denali-logo sill plates and floor mats.

'Killing a Duramax' Gale Banks YouTube series methodically tunes a diesel to death

Learning or perfecting a skill by watching YouTube videos is known as attending YouTube University. GM Authority picked up on one of the video site's more fascinating courses, hosted by Gale Banks; in a fair world, he should be referred to as Professor Banks when it comes to diesel engines and truck tuning. A few months after GM introduced the updated L5P 6.6-liter Duramax diesel V8 in the 2020 Chevrolet Silverado HD and GMC Sierra HD that ships with 454 horsepower and 910 pound-feet of torque, Banks decided he wanted to methodically tune the engine to death. The purpose of the resulting series, called "Killing a Duramax," is to push more power out of the engine in order to discover which parts break and when — or, as Banks puts it, force-feed the Duramax "until the crank hits the street and the heads hit the hood." With that knowledge, Banks can figure out all the weak points on his way to building what he calls a "Superturbo," that being a supercharged, twin-turbo race engine with more than 1,000 hp. What makes the series fascinating is Banks' knowledge, paired with the company's comprehensive iDash engine monitoring system that keeps tabs on a glut of parameters every step of the way. So for instance, you get Banks explaining the differences between inches of mercury and barometric pressure, how those are different from the water content of the air measured in grains, then showing those readouts on the iDash, then explaining in detail how they affect the air density in the Duramax system. The stock Borg-Warner variable turbo gets a lot of airtime — Banks accuses it of being "out to lunch" because he feels it's the weakest link on the engine. That turns into a turbo teardown and a deep explanation of performance pitfalls, such as when air pressure on the turbine begins to diverge from the boost pressure coming from the compressor. Banks says he can keep close tabs on where power's coming from, because the iDash monitors the horsepower contribution provided by the ambient air, the turbo, and the intercooler separately. The major changes so far are a stouter Precision 7675 turbo and TurboSmart wastegate (episode 5), a twin intake (episode 6), a custom liquid-cooled intercooler from a marine engine, a new GM oil cooler and synthetic oil (episode 10), and new injectors (episode 11).
