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 recalling over 243,000 crossovers over possible seat belt defect

2010 Buick Enclave - Click above for high-res image gallery
The summer of 2010's recall hit parade continues unabated today, with General Motors having just announced that it is asking 243,403 owners of its 2009-2010 Lambda crossovers to bring their three-row haulers in for inspection. The culprit? Second-row seat belts in select Buick Enclave, Chevrolet Traverse, GMC Acadia, and Saturn Outlook CUVs have "failed to perform properly in a crash."
According to GM, a second-row seat-side trim piece is to blame, as it can impede the upward rotation of the buckle after the seat is folded flat. As a result, if the buckle makes contact with the seat frame, cosmetic damage can occur, potentially requiring additional force to operate the buckle properly. So far, no great shakes, but in the process of applying that additional force, the occupant may push the buckle cover down to the strap, potentially revealing and depressing the red release button. As a result of this, the belt may not latch, or in certain cases, it may actually appear to be latched when, in fact, it isn't.

2017 GMC Acadia starts at $29,995

The 2017 GMC Acadia has a lower price in addition to its smaller size and 700-pound weight loss. The latest model starts at $29,995 (including $925 destination) when it arrives at dealers this spring, which is $1,905 less than last year's base version. That low price is just for the front-wheel-drive only SL trim, but there are savings throughout the 2017 lineup. The least expensive all-wheel drive version comes on the SLE model for $35,375, versus $37,100 last year (after $925 destination). The top-spec all-wheel drive Denali now costs $47,845, compared to $50,815 for the 2016 version. You can check out the MSRP for each trim in the release below. The new All Terrain model costs $40,040 and gets a more sophisticated all-wheel drive system with an active twin clutch. GMC claims the layout improves performance in wet, snowy and icy conditions. However, the trim is only available in five-passenger configuration, and storage bins in the floor replace the third-row seat. The 2017 Acadia price is also competitive with some challengers in the segment. For example, a base 2016 Honda Pilot is more expensive at $31,045 (after $900 destination), and the top Elite is $47,470, which is barely cheaper than the Denali. A base 2016 Ford Explorer is more costly at $31,995 (after $945 destination), and the Platinum for $53,915 is several thousand more than a Denali. The latest Acadia offers customers a bounty of tech and efficient powertrains. The IntelliLink infotainment system has support for Apple CarPlay and Android Auto, and there're available safety systems like front pedestrian braking and a surround view camera. Most models come with a 2.5-liter four-cylinder, which GMC estimates gets 22 miles per gallon city and 28 mpg highway with front-wheel drive. A 310-horsepower 3.6-liter V6 offers an estimated 25 mpg highway for front-wheel drive models. Both powertrains use a six-speed automatic.
