GM recalling 22K Silverado and Sierra trucks for seat issue

General Motors will recall 21,721 of its new 2014 Chevrolet Silverado and GMC Sierra pickups over front seats that could move if the vehicle is hit from behind. Affected vehicles all feature manual adjustments for the two front seats, according to a report from Automotive News.
Of the nearly 22,000 vehicles covered under the action, the overwhelming majority - 18,972 -- were sold in the United States. A further 2,575 were sold in Canada, while 103 were shipped south of the border to Mexico. Finally, another 71 were sold outside North America altogether. As of right now, there are no reports of injuries due to the defect.
Naturally, Chevy and GMC dealers will make the repairs free of charge, although it's not clear as of this writing if GM will be notifying owners or just addressing the issue at the truck's first service.

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!"

Pickup sales may hit 2M units for first time since 2007

Even as fuel prices creep back up, trucks are still a hot item among new-vehicle shoppers. To see how popular pickup trucks still are, you don't have to look any further than how much effort automakers put into the continual one-upmanship of their trucks. Backing this fact up, USA Today is reporting that the segment could top two million sales this year - a total not matched since 2007, though still far from the pre-recession, three-million-unit levels.
Through August, the Ford F-Series continues to be the segment leader with almost 500,000 units sold, but the Chevy Silverado (328,269), Ram 1500 (234,642), GMC Sierra (122,232) and Toyota Tacoma (110,293) are all seeing at least 20-percent sales increases, helping to account for around 1.44 million truck sales so far this year - not including possible outliers like the Suzuki Equator and Chevy Avalanche.
This year alone, General Motors has completely redesigned its fullsize trucks, Ram and Toyota have significantly updated their offerings, the next-gen Ford F-150 will be out next year and Nissan is promising an all-new Titan around the same time with an eventual Cummins diesel under the hood. It would seem, then, that truck sales are poised to continue their upward trend.
