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.

Ford updates Power Stroke diesel V8, strengthens F-450, tweaks King Ranch

Ford is giving its F-Series Super Duty trucks some upgrades for 2015, and we're happy to say that one of them is an improved Power Stroke diesel V8. Also, Ford is strengthening the top-of-the-line F-450 to handle more abuse. And if wild west-style luxury is your thing, the automaker has performed minor cosmetic updates to its King Ranch Edition trucks, as well.
The turbocharged 6.7-liter Power Stroke V8 is currently rated at 400 horsepower and 800 pound-feet of torque, and Ford only tells us the new and improved Power Stroke can "produce power beyond today's" engine. What, then, did Ford actually improve upon? First, the Blue Oval swapped in a new, larger turbocharger. The new Garrett GT37 turbine unit is 72.5 millimeters in diameter, eclipsing the old GT32's 64-mm diameter piece. Ford states output increases with the new turbo setup, but since the new turbocharger operates at a lower peak pressure than the old one, the automaker was able to eliminate the wastegate system and reduce the engine's complexity. Ford even redesigned the turbo's oil and cooling lines to make the powerplant simpler. A byproduct of the larger turbo is better engine exhaust braking, which is controlled manually by a button on the dashboard.
Ford claims the upgraded diesel engine is more powerful, more robust, more efficient and more refined than before.

Shelby Cobra, Mercedes 300SL and 1947 Woodie from Petersen Museum headed to auction

The changes happening at the Petersen Museum have been making the rounds in major press, but it probably won't be until August 18, during Pebble Beach, when we get the full story on what's happening; that's where and when museum reps plan on announcing the way forward for the SoCal institution. In the meantime, the museum is still reorganizing its collection, and that means auctioning some of its showpieces at this weekend's Auctions America event in Burbank.
Three of the stars are a 1964 Shelby Cobra 289, one of less than 20 produced with a three-speed C-4 automatic transmission, a 1960 Mercedes-Benz 300SL owned by actor Robert Stack and the last 1948 Ford Sportsman 'Woodie' ever produced. The Cobra, now restored to its original white exterior and red leather interior, was a factory demonstrator that first sold for $5,250. Showing just 38,950 miles on the odometer, its pre-sale estimate is $800,000 to $1 million.
The 300SL is actually a 1957 model but wasn't titled until Robert Stack took possession in 1960. The lead actor in the The Untouchables TV series used to drive by the Sunset Boulevard Mercedes dealership to ogle the car, but couldn't justify spending the money to buy it. When he and the producer of The Untouchables won Emmys for the show, the producer, who happened to be Desi Arnaz, bought the car for Stack. He owned it his whole life, it has been left as Stack drove it and still bears the California license plate "UNTCHBL."
