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."

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.

Xcar gets the scoop on Ford's strategy for the GT at Le Mans in 2016

Ford's plan to return to the 24 Hours of Le Mans in 2016 with the latest GT might have been one of the worst kept secrets in motorsports in recently memory. Even before the road car debuted at the 2015 Detroit Auto Show, rumors were flying about the Blue Oval's strategy. The wait for the official announcement just before this year's race was certainly a long one, but it was probably worthwhile just to see the competition version's spectacular looks. Xcar recently got the chance to interview Ford about the company's objectives for the new racer's development. Both the GT racing and street programs are meant as ways to advance cutting-edge technology and potentially let it trickle down to less-expensive models in the future. This is especially the case when it comes to finding ways to make carbon fiber cheaper and better. Of course, the supercar is also a showcase of what Ford can do competitively, and apparently there are patent-pending suspension parts the company isn't even talking about yet. Ford would love to score a class victory at Le Mans next year, and is pretty clear here and in its earlier promo video that it sees Ferrari as a major rival in the race. While that makes sense historically, the cross-town competitors at Corvette could be an even bigger challenger. That squad has a more recent legacy of success in the 24-hour challenge, including a victory in the GTE-Pro class this year. Related Video:
