Chevy Colorado, GMC Canyon midsize pickup trucks to get diesel engines

The market for midsize pickup trucks has all but been abandoned in the US, but General Motors is about to shake the market up with the all-new (to the US) Chevrolet Colorado and GMC Canyon. Launching next year, GM already told us that its new trucks would be a "fuel-efficient alternative" to fullsize trucks, and aside from the smaller size, Automotive News says that these trucks will accomplish this with a diesel engine.
According to the AN report, the next-gen Colorado and Canyon will offer a small, four-cylinder Duramax turbo diesel with a displacement of either 2.5 or 2.8 liters - both engines are currently used in this truck for other markets. This would allow GM to join the Cummins-powered Nissan Titan and Ram 1500 EcoDiesel as the only non-HD trucks in the US to offer diesel. The article goes on to say that the diesel versions of the Colorado and Canyon would launch about a year after the trucks go into production in fall of 2014.

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!"

2015 GMC Yukon erupts into flames during Anaheim test drive [w/video]

A 2015 GMC Yukon burst into flames while on a test drive in Anaheim, CA on Sunday after smoke filled the cabin. Residents of the neighborhood where the driver abandoned the redesigned Yukon reported hearing a series of small explosions (likely the tires, based on the video), according to a report from KTLA and The Los Angeles Times.
No one was injured in the incident, which The Times reports occurred after a possible oil or fluid leak. As you can see in the image above, the Yukon was engulfed in flames, although the Anaheim Fire Department was able to put out the blaze in about 15 minutes.
"We're very lucky that no one got hurt, and it was in an area that... was safe," Lt. Tim Schmidt of the Anaheim Police Department told KTLA reporters. "If there was any place that was going to be safe, it would be this area. It's very open. It worked out for us."
