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 to squeeze out more production capacity for midsize trucks

General Motors was predicting a strong showing for the Chevrolet Colorado and GMC Canyon before they debuted, and demand among dealers for the midsize trucks even exceeded company's expectations. The positive situation has left GM with a problem, though: finding ways to increase capacity for the pickups at the Wentzville Assembly plant in Missiouri. With a third shift already running, GM has continued to look for ways to build just a few more of the trucks at the plant. The company has plans to hire as many as 1,000 more workers for the Saturday and Sunday shifts to construct an additional 2,000 pickups a month, according to unnamed insiders at the factory speaking to Automotive News. The little adjustments even extend to getting rid of an unpaid break to add 18 minute of assembly time over the course of a day, which equals about 3,500 more vehicles a year. All of this effort comes because the trucks are in such high demand. According to GM's figures, the company has delivered a combined 35,720 units of the Colorado and Canyon from January through April 2015, and the Chevy was the fastest-selling truck in the US for the previous three months. In May, it spent an average of just 12 days in showrooms before being snapped up. And even better for the company, 43 percent of these buyers came from other brands. According to Automotive News, the most popular trade-ins have included the Ford F-150, Toyota Tacoma, and Dodge Dakota. Related Video:

Chauffeur attacks motorist in road rage incident

A California man was the victim of an intense and violent road rage attack on the 405 freeway on Tuesday, but when the police were called they told the driver to shake it off. Shahnam Asbaghi told KTLA that the altercation began when a GMC Yukon private car began tailgating him. "This limousine Yukon driver was just tailgating me the whole time since when I got onto the 405 North," Asbaghi told reporters. "It was so bad I actually got scared and nervous so I exited early." When Asbaghi exited the freeway, the Yukon followed and rear ended him at the bottom of the ramp. "He just rammed me with his car at probably 25, 30 miles per hour," said Asbaghi. "When he hit me he got out of his car, came around to the driver's side and punched my window four or five times. Then he ran back to his car, got in his car, and drove away." Startled, Asbaghi followed his assailant in an attempt to get the Yukon's license plate number. After a quick chase, the Yukon stopped near Sepulveda Boulevard and Sherman Way where the driver got out of the truck, retrieved a long, unidentified item from the rear cargo area, and attacked Asbaghi's car again. Video shot by Asbaghi shows the chauffeur striking the driver's side window with the object, tossing it back in the Yukon, then leaving the scene. Asbaghi called 911, but the police weren't impressed. "Because my head wasn't smashed, because the window wasn't smashed, no harm no foul is what they told me," Asbaghi told KTLA. The cops did make the drivers exchange information, but no arrests were made. The Los Angeles Police Department is now looking into the incident to make sure they handled the situation correctly. The day after the attack, L.A. Private Car announced via Twitter that they fired the angry Chauffeur after reviewing the footage.
