NHTSA upgrades Ford floor mat unintended acceleration probe

According to a Bloomberg report, the National Highway Traffic Safety Administration has upgraded an investigation into complaints of unintended acceleration lodged against Ford vehicles. The investigation began in June of 2010 when just three complaints had been received and it only concerned the Ford Fusion and Mercury Milan, but this was at a time when the phrase "unintended acceleration" made grown men go pale. With 49 additional complaints received since then, the investigation has been reclassified as an engineering analysis - the last phase before a recall - and it has been expanded to include the Lincoln MKZ, making for a total of "around 480,000" units affected between the three sedans from the 2008 to 2010 model years.
The ostensible cause is that floor mats are trapping the accelerator pedal, but according to a Ford statement at the time, the entrapment is due to owners placing the optional all-weather floor mats, or aftermarket floor mats, on top of the car's standard floor mats. NHTSA has backed up that assessment, pinning the blame on "unsecured or double stacked floor mats."
On the face of it, it would appear that NHTSA has upgraded the status not because of Ford's error, but owner error, and Ford has stated publicly that it is "disappointed" in NHTSA's move. On top of NHTSA still being skittish after that other unintended acceleration debacle, it could be seen to be taking its time investigating all of the variables: it's reported that Ford changed its accelerator pedal design in 2010, a "heel blocker" in the floorpan has been considered a potential culprit in how the floor mats could be trapping the pedal, some drivers have said the floor mats weren't anywhere near the pedal, and according to a report in the LA Times, in "a letter sent by Ford to NHTSA in August 2010, the automaker said it found three injuries and one fatality that 'may have resulted from the alleged defect.'"

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.
