2015 GMC Sierra Elevation Edition goes dark, looks good

Forget about the so-called sporty Chevrolet Silverado Rally Edition. If you want a General Motors pickup with some added style, this one looks like a more cohesive, well-done package to our eyes (though it's also not "sporty," despite GM using that term over and over again). It's called the GMC Sierra Elevation Edition, and it hits dealerships later this year.
For its more stylish truck, GMC has fitted the 2015 Sierra Double Cab with a body-colored grille surround, door handles, mirror caps, side moldings and bumpers. The truck also rides on black 20-inch aluminum wheels.
The Elevation Edition, which GMC contends qualifies as a sport truck, comes standard with the Sierra's 285-horsepower, 4.3-liter V6, though buyers can opt for the more powerful 5.3-liter V8 with 355 hp. Other standard goodies include OnStar with 4G LTE connectivity and Bluetooth, all housed in the 4.2-inch Intellilink color display.

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!"

GMC Canyon's jump seats innovate to keep kids safe [w/video]

We dig simple solutions to problems. There's something highly gratifying about making a minute change to fix something, rather than tearing up the playbook. That's what GMC has done with the new Canyon midsize pickup.
When putting a car seat in, car seat manufacturers require that at least 80 percent of the seat's base fit on the bottom cushion. That's a big problem in extended-cab pickups like the Canyon, which feature jump seats with shorter bottom cushions, in place of the larger, more traditionally designed bench.
The Canyon gets around this with extendable jump seats - simply pop out the headrest and slot it into the bottom seat cushion, and the truck can now easily accommodate a child's seat.
