Ford F-150 EcoBoost in NHTSA probe for acceleration issue

According to Automotive News, the National Highway Traffic Safety Administration is launching a probe into 400,000 Ford F-150 models over possible acceleration problems. According to the article, NHTSA has received 95 reports "alleging incidents of reduced engine power during hard accelerations" on 2011 to 2013 F-150 models equipped with the company's 3.5-liter EcoBoost V6 engine.
Automotive News reports that Ford has issued three technical service bulletins "related to intermittent stumble/misfire on acceleration from highway cruise in humid or damp conditions," according to the government agency's documents. About one third of the 95 reports NHTSA has received cited humid or rainy conditions when these problems allegedly occurred.
These technical service bulletins have allowed dealers to address a "condition related to moisture accumulation in the charge air cooler during extended highway cruising at constant throttle in humid or damp conditions," AN reports, citing NHTSA documents. Furthermore, the TSB outlines details for "reprogramming the powertrain control module with the latest calibration and installing a new CAC and air deflector plate."

Shelby GT500 and Roush Stage 3 go head to head at the drag strip

The Ford Mustang is a brilliantly affordable source of horsepower, with a base 300-plus-horsepower version available for well under $30,000. Jumping up to about $35,000 will get you a solid 420 horsepower from a high-revving V8, while those with some extra disposable income can get a pair of 600-plus-horsepower monsters. Both the Roush Stage 3 with its Phase 3 package and Ford's factory Shelby GT500 even crest the 650-horsepower mark, with 675 and 662 ponies, respectively.
Naturally, someone needed to find out which of these hi-po Mustangs was the quickest. And while this video is quite obviously a dealership commercial, at least there's some solid drag racing between two of the most powerful performance machines available for under $100,000.
With two NHRA drag racers at the wheel, the Stage 3 and GT500 go head to head for three races. Scroll down below to see the results in the full video.

Radical RXC is a Mustang-hearted racecar for the road

Radical has been building fantastic open-cockpit racers and roadcars for years, for the track day enthusiast who wants a vehicle that looks like it could show up for a start at the 24 Hours of Le Mans. The company's latest creation is the RXC, and while this coupe looks like a prototype racer, it's road legal in the UK and in some parts of the US. When testing a car this, um, radical, the first thought is likely to get it to the track for some big slides and wide open acceleration, but XCar Films takes the opposite approach in its latest video to learn how this racer fares on public roads. The version tested here is the standard RXC with the 3.7-liter V6 out of the Ford Mustang tuned to 350 horsepower with a seven-speed sequential gearbox; but Radical also offers the same engine with 380-hp, a 454-hp Ford EcoBoost 3.5-liter twin-turbo V6, or even a 500-hp V8. Even in the most basic guise, it's a handful to control in the wet, if this video is any indication. The cliche of a road-legal racecar is bandied around a lot in the motoring world, but it truly applies to the RXC. The only problem with seeing the RXC exclusively on the road is that it can never really open up and show its full potential. This racer is indeed chomping at the bit to rocket off into the horizon, but all those pesky road safety laws hold it back. Still, the video is a chance to get a better impression about this thoroughbred sports car. Scroll down to check it out. This content is hosted by a third party.
