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!"

GM renders new Chevy Colorado, GMC Canyon pickups

At a series of industry seminars in Traverse City, MI today, General Motors executive vice president Dan Ammann gifted us with our first glimpse of the upcoming midsize pickup range from Chevrolet and GMC.
Just two slivers of nose are all we can see of the soon-to-be announced Chevy Colorado and GMC Canyon, though the teaser image does make plain that the pair will follow the styling cues (at least up front) found on big brothers Silverado and Sierra.
GM hasn't given us much in the way of detail in its ultra-brief press release that accompanied the teaser image, which is to be expected. We're told only that the pair of trucks are designed to be "capable, versatile and fuel-efficient alternatives to full-size pickups" and that production will start sometime in 2014, at the Wentzville, MO assembly center.

Best cars for snow and ice in 2023 and 2024

What's the best car for snow? The real answer is "the one with winter tires." What do we mean by that? You could have the finest, most advanced all-wheel-drive system or four-wheel drive in the world, but if you're running all-seasons (the spork of tires), your fancy four-wheeler won't matter much. The odds are, any vehicle on the road running good winter tires will probably perform adequately in slippery, slushy and/or snowy road conditions. (Here's a more complete explanation of why winter tires are totally worth it). In other words, you don't really need any of the cars on this list. With a set of winter tires, countless others will do the job, and even these will be at their best with proper rubber. You can find a variety of winter tires for your car here at Tire Rack. Keep in mind that you will need a full set of four snow tires for safety and performance, no matter what you're driving. The days of your dad putting just two snows on the family truckster to get it moving in a straight line are long gone. Don't get us wrong, getting a car that performs well in snow and ice is still a worthy criteria for car buyers. According to the U.S. Transportation Department, 70% of Americans live in places that get snow and ice. And much of the country has been blasted with arctic air for much of the new year. So let's look at the cars. First, we're highlighting choices for a variety of buyers and price points. Second, we're not just considering snow; we're considering general wintery conditions people will experience driving to work or school. As such, these are all choices with advanced all-wheel-drive systems, usually with "torque-vectoring" systems that not only automatically shunt power front and back, but side to side between the rear axles. Most have extra ground clearance for getting through deep snow, and we prefer those vehicles with more responsive steering, throttles and transmissions that provide a greater sense of vehicle control in slippery conditions.    Acura RDX Read our Acura RDX Review Acura's Super-Handling All-Wheel Drive system was one of the first to offer torque-vectoring, and besides often being touted for its ability to greatly enhanced dry-road handling, its benefits in the slick stuff can be profound. It's actually surprising that Acura hasn't leaned into this capability further by offering more rugged versions of its vehicles.
