NHTSA investigating Ford's solution to May 2014 power steering recall

The National Highway Traffic Safety Administration is investigating a complaint that Ford's response to a May 2014 recall of the 2008 to 2011 Ford Escape and Mercury Mariner doesn't quite go far enough to solve a troubling power-steering problem. Roughly a year ago, Ford recalled nearly a million vehicles after it was found that a problem with the torque sensor's communication with the power steering control module could cut steering assistance for drivers. While manual steering would still be available, the problem was enough to ask drivers to report in to have the PSCM inspected, and if necessary, replaced (along with the torque sensor, or in dramatic cases, the entire steering column). That would only happen, though, if trouble codes were being thrown. If there weren't any problems, dealers were told to simply update the PSCM's software so that any issues between it and the torque sensor would simply throw a visual and audio warning – power steering would still be maintained. The petitioner claimed that following the recall work, he still experienced a problem with the torque sensor. According to NHTSA, a claim was made that Ford didn't go far enough in its solution to the problem, and that "the software update itself may in fact cause further issues with the affected vehicle's power steering, causing it to fail, and ultimately requiring replacement of the torque sensor or entire steering column." The petition was filed in early February and is now officially being looked into by NHTSA.

2016 Ford Shelby GT350 Mustang rated at 526 hp, 429 lb-ft

When Ford debuted the Shelby GT350 Mustang at the LA Auto Show last year, we were told it'd have more than 500 horsepower and over 400 pound-feet of torque. And indeed it does; Ford confirmed today that its hot 'Stang will make 526 hp at 7,500 rpm and 429 lb-ft at 4,750 rpm. Compared to the GT350's main rival, the Chevy Camaro Z/28, that's an increase of 21 hp, but a loss of 52 lb-ft. That said, this Mustang packs some serious prowess, especially in its most hardcore GT350R trim. It sounds pretty wicked, too. It's worth noting that both the standard GT350 and GT350R use the same engine, with the same output ratings. It's also worth noting that this is a flat-plane-crank engine. It's the most powerful naturally aspirated engine Ford has ever made, with 102 hp per liter. Redline is 8,250 rpm. It's a lightweight engine, too – the 5.2-liter mill weighs less than Ford's own 5.0-liter Coyote V8. Perhaps most impressive is the price point for the 2016 Shelby GT350. The standard car comes in at $47,870, while the GT350R will command $61,370 – a big drop over the Camaro Z/28 and it's $73,300 sticker price (including destination but not gas guzzler charges). Ford confirmed the power output news at a media briefing today near its headquarters in Dearborn, MI. Stay tuned for more information as it becomes available. Related Video:

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!"
