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."

40+ cars that barely avoid the gas guzzler tax

The Gas Guzzler schedule, with mpg ratings and charges that haven't changed since 1991, lays out which fuel-swillers owe what to Uncle Sam.
I started thinking about the "Gas Guzzler Tax" - considerably less well known as The Energy Tax Act of 1978 - when I was driving Dodge's new Challenger SRT Hellcat last week. Unsurprisingly for a car that can burn 1.5 gallons of gas per minute at max tilt, theoretically able to empty a full tank of premium in about 13 minutes, the Hellcat will be subject to the Gas Guzzler Tax schedule when it goes on sale.

2015 Ford Expedition stays the course, adds EcoBoost power

The era of the body-on-frame, fullsize SUV is rapidly vanishing in favor of smaller, unibody crossovers. However, Ford still sees life in the segment with the reveal of the updated 2015 Expedition, now available (solely) with the company's 3.5-liter EcoBoost V6. The new truck will make its public debut at the 2014 DFW Auto Show in Dallas on February 19.
The loss of the previous 5.4-liter V8 in favor of Ford's 3.5-liter, direct-injected, twin-turbocharged V6 engine might rankle some of the Expedition's fans, but Ford claims that the change gives the SUV better fuel economy, more power and increased low-end torque than before. Unfortunately, official engine specifications won't be released until later this year, but Ford says engine output will be similar to the 365 horsepower and 360 pound-feet of torque that this powerplant produces in other applications. The EcoBoost is mated to a six-speed automatic transmission, and the SUV now uses electrically assisted power steering, for an even greater fuel economy advantage. Ford claims this also allows for better maneuverability at low speeds and better feel at high speeds.
Exterior styling is basically unchanged for 2015. The front end has the same three-bar chrome grille and headlight design, but the lower air dam gets added chrome and LED lamps. The rear gets more brightwork on the hatch, and there's a chrome-tipped exhaust pipe. As before, Ford is offering the Expedition in two wheelbase lengths - 119 inches and 131 inches. A new, optional, continuously controlled damping system alters suspension settings constantly based on 46 parameters and offers comfort, normal and sport modes (just like the Expedition's sister, the recently refreshed and decidedly less-attractive Lincoln Navigator).
