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!"

Chevy Express 1500, GMC Savana 1500 get the axe

Fans of truck-based, light-duty vans can officially pour one out for the Chevrolet Express 1500 and GMC Savana 1500, as General Motors has officially put its long-serving big/little rigs out to pasture. Things aren't quite as sad as they sound, though. The heavier-duty 2500 and 3500 vans will soldier on, in order to duke it out with the largest members of Ram ProMaster, Ford Transit and Mercedes-Benz Sprinter families.
The move does seem to make a lot of sense. According to GM, customers only purchase the 1500-spec Chevrolet 23 percent of the time, while the GMC captures a mere 7 percent of the Savana family's sales. With numbers like that, it's no shock that GM thinks it can shift some of its buyers into its van family's more capable variants. "We knew we could move a lot of our 1500 customers into 2500-series territory," said GM's Joe Langhauser, the product manager for the company's full-size vans.
It's not just simple sales figures dictating the move, though. The 1500 line is taking up some valuable factory space that will be better spent on an eagerly anticipated new product.

GM looks to combat high theft rates on SUVs with added tech

The Cadillac Escalade has been at or near the top of most-stolen and insurance-loss lists for more than seven years, until it dropped to number six earlier this year. In 2011 it was fitted with a host of new security features to address its easy-to-override features and that has brought the number of thefts down, but when eight of the ten most stolen rides are large SUVs from General Motors, no one will argue that something else needs to be done.
Thus, GM has fitted this same theft-deterring tech to the 2015 Suburban, Tahoe and Yukon. The Suburban and Tahoe will get the steering lock that the Escalade and Yukon already get, plus bolted-down third-row seats to deter thefts like this, stronger door lock cylinders and shields, and side-cut keys to inhibit picking.
Additional security measures in a Theft Protection Package can be purchased for $395, consisting of sensors on the greenhouse glass and interior, an incline/tilt sensor and added "key control systems" to make it more difficult for the men in black balaclavas to steal what you bought.
