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.

Nuclear-powered concept cars from the Atomic Age

In the 1950s and early 60s, the dawn of nuclear power was supposed to lead to a limitless consumer culture, a world of flying cars and autonomous kitchens all powered by clean energy. In Europe, it offered the then-limping continent a cheap, inexhaustible supply of power after years of rationing and infrastructure damage brought on by two World Wars.
The development of nuclear-powered submarines and ships during the 1940s and 50s led car designers to begin conceptualizing atomic vehicles. Fueled by a consistent reaction, these cars would theoretically produce no harmful byproducts and rarely need to refuel. Combining these vehicles with the new interstate system presented amazing potential for American mobility.
But the fantasy soon faded. There were just too many problems with the realities of nuclear power. For starters, the powerplant would be too small to attain a reaction unless the car contained weapons-grade atomic materials. Doing so would mean every fender-bender could result in a minor nuclear holocaust. Additionally, many of the designers assumed a lightweight shielding material or even forcefields would eventually be invented (they still haven't) to protect passengers from harmful radiation. Analyses of the atomic car concept at the time determined that a 50-ton lead barrier would be necessary to prevent exposure.

Did a US automaker blow the whistle on Hyundai, Kia fuel economy issue?

In all of the most hotly contested mainstream segments of the motoring universe, the difference of one mile per gallon averaged on a widow sticker can mean the difference between a sale and a walk-off - to say nothing of two or three mpg. So, when Hyundai and Kia were forced to reveal that many of their 40-mpg ratings were actually 38s and 37s, well, it made for big news.
It also, conceivably, made for a competitive disadvantage immediately, when the Korean automakers' products were being shopped versus the guys down the block. And it's that disadvantage that makes a recent story from Automotive News so juicy.
AN is reporting that Margo Oge, former head of the Environmental Protection Agency's Office of Transportation and Air Quality, got a tip in 2010 that Hyundai/Kia were "cheating" to get its impressive fuel economy numbers. The tip, said Oge (who retired from the EPA this past September), came from a senior vice president from a domestic automaker. The source was credible enough for Oge to launch an audit of the Hyundai figures, which ultimately lead to the debacle that we reported on a few months ago, and that the Korean company has been trying to bounce back from ever since.
