NHTSA closes Ford F-150 EcoBoost acceleration probe

Typically when we report on the findings of an investigation from the National Highway Traffic Safety Administration, it's because the government body has discovered a safety issue and prescribed a recall. In this case, however, NHTSA has closed an investigation into a reported performance deficit without ever getting to the recall stage.
The issue revolves around the Ford F-150 - specifically those equipped with the 3.5-liter EcoBoost engine - of which some 360,000 were built in the 2011, 2012 and 2013 model years. After receiving an initial 95 complaints, NHTSA opened an investigation last May - almost a year ago - into the reported issue of reduced engine power under hard acceleration. The agency has since received a total of 525 such complaints, and Ford itself reported receiving over 4,000.
Together, NHTSA and Ford determined that the problem resulted from cylinders misfiring, an issue itself stemming from water getting into the charge air cooler (CAC) mated to the turbochargers. In particularly humid or rainy conditions, water was found to get into the CAC, causing some of the cylinders to misfire, which in turn triggered the ECU to disable those cylinders in order to protect the catalytic converter from damage.

Porsche 911 Turbo and Nissan GT-R Nismo star in World's Greatest Drag Race 4

We love Motor Trend's annual World's Greatest Drag Race video. Now back for its fourth appearance, the idea of lining some of the world's fastest cars up for a ten-wide, straight-line, full-throttle run is, well... it's pretty freaking badass.
The lineup this year boasts some impressively fast cars to be sure. The group of ten includes the following darlings: Alfa Romeo 4C, BMW i8, BMW M4, Chevrolet Camaro Z/28, Ford Fiesta ST, Jaguar F-Type R Coupe, Nissan GT-R Nismo, Porsche 911 Turbo S, Subaru WRX STI and, last but not least, the Volkswagen GTI. Give us any one of those for the weekend, and we're happy to take the keys.
It must be said though, that for a publication that draws as much water as Motor Trend does, there are some big cars that we might expect to be here instead. The Lamborghini Huracán or Ferrari 458 Speciale would have added some exotic flare to the list, and the omissions of the Chevy Corvette Stingray (for the second year in a row) and the Dodge Challenger Hellcat are real head-scratchers.

Ford GT successor to debut in Detroit and go racing

Anticipation for all of the exciting reveals at the 2015 Detroit Auto Show just a few weeks away is building to a fever pitch, and rumors are mounting that Ford has a big surprise in store in the shape of a future performance halo model. Insider sources speaking to Autoweek claim the next Ford supercar is definitely going to be revealed at the Detroit show in early January. However, the model is not necessarily the next-generation Ford GT in terms of its name or design aesthetic. Instead, one of these people indicates that the new halo model might drop retro styling altogether. If the latest reports are to be believed, Ford's high-performance project goes beyond something to just grab headlines and rocket down the street. According to Autoweek, the automaker is also reportedly employing Chip Ganassi Racing to run a two-car racing effort in the Tudor United SportsCar Championship in 2016. That would allegedly include a trip to the 24 Hours of Le Mans to race on the 50th anniversary of the Ford GT40's win in 1966. The speculation goes that at least the racing version might use a twin-turbo EcoBoost V6 for power. However, the motorsports part of the program may not be announced during the auto show reveal. Rumors about the new halo car from the Blue Oval and its racing intentions have been percolating for months. The company might have considered an LMP2 entry, but speculation popped up later about the production supercar. A more recent report suggested that Ford might show a new Shelby GT350R Mustang, a successor to the F-150 Raptor and next Ford GT in Detroit.
