Ford adding stop-start to all major model lines

Ford has gone all-in on its efforts to offer most of its new vehicles with a fuel-efficient EcoBoost engine, but the automaker is reportedly preparing to take another big step toward improving vehicle efficiency. Automotive News is reporting that Ford will soon expand the availability of start-stop technology, which was first offered - presumably the first non-hybrid vehicle, that is - on the 2013 Fusion (equipped with the 1.6-liter EcoBoost engine) as a $295 option.
The benefit of start-stop is reduced fuel consumption as it shuts the engine off at long stops, and AN quotes Ford as saying that drivers can save more than $1,000 on fuel costs over five years. Despite this, the option hasn't been popular on the Fusion thus far, but it could be more beneficial on bigger vehicles like the F-150. Ford also said that the next-gen Edge, which was previewed in concept form at the LA Auto Show, will be equipped with auto start-stop to help make the EcoBoost engines even more efficient.

Ford lowers MPG ratings on six vehicles

Ford has announced that it will be lowering the fuel economy ratings on a number of its 2013 and 2014 model year vehicles after an error was discovered in the company's internal testing data. The EPA has been notified.
Worryingly for Ford, the vast majority of the vehicles affected are hybrids, including the C-Max, Fusion and MKZ in both hybrid and plug-in varieties (where applicable). Also covered as part of the rerating is the entire lineup of 2014 Fiesta engines, with the exception of the ST, including the turbocharged, three-cylinder EcoBoost.
The C-Max was originally rated at 47/47/47 mpg, but dropped to 43/45/40 last year and now to 40/42/37.

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.
