2014 GMC Sierra Regular Cab revealed

Despite initially launching in just the Crew Cab configuration, the lineup of 2014 GMC Sierra and 2014 Chevrolet Silverado trucks will eventually grow to include three cab sizes and three bed lengths. Oddly enough, our first look at the Regular Cab bodystyle has arrived in a General Motors press release discussing the aerodynamics of the new truck, with an image showing a Sierra Regular Cab testing in the wind tunnel. GMC's website says that Regular Cab and Double Cab models will be available by summer.
While it really didn't take too much imagination to figure out what the two-door version would look like, this Regular Cab Z71 looks pretty sharp with its standard-length (6.5-feet) bed - a longer bed will also be offered. In regards to the aero tuning of the 2014 Sierra, these images show just how far GM has gone in maximizing the truck's fuel efficiency and reducing its noise, vibration and harshness (NVH) levels. Interestingly, the press release shows visual evidence that keeping the tailgate up is best for aero - there's always been some Mythbusters-level contention about such things -but GM also says that adding tonneau covers (preferably soft) and running boards can also help improve the overall aerodynamics. Scroll down for all of this aero info in the official press release.

2016 GMC Sierra Denali Ultimate wants to take even more off the top

What do you do when getting to the top of Denali isn't enough? You create a higher peak called Denali Ultimate. That's what GMC has done with the 2016 Sierra, the new Sierra Denali Ultimate adding even more content and showing off the truck's refreshed face and new Denali grille. The reasoning behind this truck is perfectly sane. GMC says that in 2013 it had zero percent of the premium light-duty truck market; since that time, the brand says the segment (with an average transaction price beyond $55,000) has grown by a factor of ten, and the Sierra Denali has given GMC a 15.5-percent share. When it goes on sale in in the first quarter of next year, it can be optioned on the four-wheel drive 1500 Crew Cab with either the five-foot-eight or six-foot-six-inch bed. Standard equipment includes a sunroof, Lane Keep Assist, automatic headlights, Tri-Mode Power Steps, chrome tow hooks, and 22-inch wheels. The press release below has more. GMC Sierra Denali Ultimate: The Pinnacle of Premium Unique 22-inch wheels, expanded package of standard content drives exclusivity DETROIT, Tuesday, Nov. 17, 2015 – GMC is taking the range-topping style, craftsmanship and capability of the Sierra Denali even higher with the 2016 Sierra Denali Ultimate. It builds on the Sierra Denali's already class-leading attributes with a package of precision-crafted features designed to elevate its comfort, design and capability in the growing premium niche of the full-size truck market. GMC introduces the Sierra Denali Ultimate today, ahead of its public debut at the Los Angeles Auto Show. It goes on sale late in the first quarter of 2016. "The Sierra Denali has helped drive the growth of premium portion of the light-duty crew cab segment," said Duncan Aldred, vice president of GMC Sales and Marketing. "This truck is the ultimate expression of the Sierra Denali with greater emphasis on the bold and refined presence and advanced features that make Denali models synonymous with precision and exclusivity." Thanks in large part to Sierra Denali, which was redesigned in 2014, GMC commands 15.5 percent of the premium full-size truck segment, where average transaction prices exceed $55,000. The segment has nearly doubled in 2015 and grown tenfold since 2013, when GMC had zero percent of the market. In fact, Sierra Denali has helped GMC earn a higher share of the premium portion of the light-duty crew cab segment than of the overall full-size pickup segment.

Diesel Power finds the ultimate modified oil-burner

For nine years, Diesel Power magazine has run the Diesel Power Challenge, this year's grindfest being "a week-long torture test that features seven events, nine trucks, 8,000 horsepower, and nearly 15,000 pound-feet of torque." The road to being crowned "the most powerful truck" starts with a dyno run, and then continues through the completion of a CDL-style obstacle course, an eighth-of-a-mile drag race while towing a 10,000-pound trailer, a quarter-mile drag race without a trailer, a fuel economy test in the mountains and finally a sled-pulling test through a 300-foot-long packed-mud pit.
What kind of trucks get into such a fight? Last year's winner, for instance - who upgraded his truck this year to prove he didn't "luck into the win" - drives a 2008 Ford F-250 Super Duty with a 6.4-liter Power Stroke V8 upgraded with a custom intake, Elite Diesel triple turbos and a two-stage nitrous system. Another competitor has a 2005 Dodge Ram 2500 powered by a 5.9-liter Cummins inline-six, upgraded with Garrett turbos, dual-stage nitrous, a seven-inch exhaust stack and twin fans built into the bed to cool the Sun Coast Omega transmission. The numbers on that truck: 1,255 horsepower, and 2,063 pound-feet of torque at the wheels. Naturally, as the image above might suggest, things don't always end well.
You'll find all five videos covering this years challenge below. A scene in the dyno video sums it all up perfectly: a competitor leaves his nitrous on too long and the crew is treated to some ominous poppings, he leans out the window, throws both hands up and shouts, "Amer'ca!"
