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.

eBay Find of the Day: 1970 Ford Torino King Cobra prototype

Over the last decade or so, competition in NASCAR has led to some pretty funky looking racecars. And when the sport was still up and coming, the tight competition actually led to some interesting production cars. The Dodge Charger Daytona and Plymouth Superbird are perhaps the most well-known cars of the sport's "aero wars" era but the Ford Torino King Cobra might have been the most memorable of all, if not for some different homologation rules established in 1970. The Torino King Cobra never made it to production and never competed in NASCAR, but three examples exist including this one now for sale on eBay.
Designed as a successor for the aero-tuned Torino Talladega, the Torino King Cobra has a sleeker front end with hidden headlights and a sloped nose. As the story goes, NASCAR made a rule change in 1970 requiring 3,000 of the vehicles to be produced, which was substantially more than the 500 units required by the previous rule. One of the three prototypes ever built - and the only one built with the Boss 429 engine - is now for sale on eBay with a starting bid of $500,000. With a little more than three days left on the auction there are still no bids, but in the grand scheme of things this seems like a relatively fair price for a rare piece of automobile and racing history.

Ford opens the doors on its Swedish rally skunkworks

It's always amazing to see how different kinds of racecars are made. Formula One racers are often constructed in modern architectural marvels that hint at some of the cutting-edge technology going into the racing. Conversely, rallying is all about sliding around on a varied course as fast as possible, but it often leaves a vehicle caked in mud. So it makes some sense Olsbergs MSE, or simply (OMSE) rally car shop in Nynashamn, Sweden, shows technological sophistication in a more down-to-earth setting. It builds Ford Fiesta ST racers for Global Rallycross there, and this new video gives viewers a tour through the work.
Former rally driver Andreas Eriksson runs OMSE. These days instead of racing, he and the company's 46 employees are building Ford racers from scratch. A ton of work goes into constructing each one, and according to Eriksson, it takes 400 hours to complete each body. At times, things are so busy that some of the technicians live in the shop in apartments that are on premises. There's even a restaurant to keep them fed. Sadly the dyno room is empty during this visit, though.
By the time OMSE is done, a rallycross car might resemble a Fiesta ST on the outside, but as you see in the video, it's a completely different beast underneath. Check out the work it takes to build one of them, and scroll down to read more about it in the official release.
