GM recalling 70k Chevy Malibus, Pontiac G6s over steering issue

A problem with the power steering system in the Chevy Malibu and Pontiac G6 has prompted General Motors and the National Highway Traffic Safety Administration to issue a recall for an estimated 69,633 vehicles. The issue revolves around the electric power steering assist, which could suddenly fail and increase the risk of a crash, especially at low speeds where the power steering is most helpful. The recall affects 2006-2007 Chevy Malibu sedans and Malibu Maxx wagons (specifically those manufactured between April 1, 2006, and June 30, 2006), as well as the Pontiac G6 (which was offered as a sedan, coupe or convertible) from the same model years and manufactured from April 18, 2006, to June 30, 2006. Owners of the affected units can expect to hear from the manufacturer with instructions to bring in their vehicles to their local dealers to have the torque sensors in the power steering system replaced. RECALL Subject : Sudden Loss of Electric Power Steering , 1 INVESTIGATION(S) Report Receipt Date: FEB 04, 2015 NHTSA Campaign Number: 15V064000 Component(s): STEERING Potential Number of Units Affected: 69,633 Manufacturer: General Motors LLC SUMMARY: General Motors LLC (GM) is recalling certain model year 2006-2007 Chevrolet Malibu and Malibu Maxx vehicles manufactured April 1, 2006, to June 30, 2006, and 2006-2007 Pontiac G6 vehicles manufactured April 18, 2006, to June 30, 2006. In the affected vehicles, there may be a sudden loss of electric power steering (EPS) assist that could occur at any time while driving.

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!"

Chevrolet Chaparral 2X Vision Gran Turismo could only work in a video game [w/video]

There's something wondrous about the Vision Gran Turismo series of concepts that has let companies go wild with completely imaginary concepts for Gran Turismo. For Chevrolet's crack at the idea, it has taken a page out of its performance past with the Chaparral Can-Am racers of the '60s and '70s, with its designers having reinterpreted that period look for the future of motorsports as the Chaparral 2X. In real life, the 2X looks even better than in earlier photos. The design takes inspiration from someone in a flying suit with head down and arms outstretched, an influence you can really see that in the vehicle's shape. The driver lies facedown inside with the instruments projected onto a visor. Unfortunately, the powertrain here is a complete flight of fancy and works purely in the video game world. It imagines a laser propelled by lithium-ion batteries and an air-powered generation to make 900 horsepower. The 2X has a theoretical top speed of 240 miles per hour and hits 60 mph in a lightning-quick 1.5 seconds. Scroll down to see the concept on video with Chevrolet designers describing their inspiration and read the company's full announcement. It's also downloadable in Gran Turismo 6. Chevrolet to Show Chaparral Vision Gran Turismo Concept Boundary-pushing, Chevy-powered race cars changed motorsports design DETROIT – When racers Jim Hall and Hap Sharp founded Chaparral Cars in 1962, few could have guessed how they would shake up the conformities of the racing world – and fundamentally change it. Through pioneering applications of aerodynamics and aerospace technology, and a partnership with Chevrolet Research and Development, Chaparral Cars advanced the science of racing cars. It also triumphed on the track over well-established sports car companies from around the world, using Chevrolet horsepower. It was that spirit of innovation that inspired the Chevrolet Chaparral 2X VGT concept race car developed for the Vision Gran Turismo project, which celebrates the 15th anniversary of PlayStation® racing game Gran Turismo by inviting manufacturers to give fans a glimpse into the future of automotive design. It will debut at the Los Angeles Auto Show, Nov. 19, and gamers will be able race the Chaparral 2X VGT following the release of an online update for Gran Turismo 6 during the holiday season.
