NHTSA investigating 725k Ford, Mercury vehicles for stalling issue

Owners of Ford Escape, Mercury Mariner, Ford Fusion and Mercury Milan models, listen up. According to a report on Automotive News, the National Highway Traffic Safety Administration has opened an investigation into these four vehicles totaling an estimated 725,000 units. The investigation appears to center around a malfunctioning throttle body on non-hybrid models of the 2005-2012 Escape and 2011-2012 Fusion. With Mercury dying off after the 2011 model year, this probe will also apply to the 2005 through 2011 Mariner and the 2011 Milan. There has been some discussion around the Escape stalling issue for some time now, but this investigation appears to be larger in scope than before.
Though not a recall yet, NHTSA's Office of Defects Investigation (ODI) has received 123 complaints of stalling or surging vehicles, while Ford itself has logged 1,472 complaints. The investigation report, which is posted below, seems to indicate that a faulty circuit board for the throttle body could cause the vehicle to go into limp mode, which, according to NHTSA, could cause complaints of both stalling and surging.

Ford, Samsung shack up to bring regen braking to non-hybrid models [w/video]

Ford must be desperate to get itself ready for the beach this summer because it is really trying to get into shape. Shortly after unveiling the Lightweight Concept that cut the weight of a Fusion down to that of a Fiesta, it's now the rest of the line's turn for improvement. The company is wrapping up a 10-year research project aimed at developing next-gen automotive batteries to improve efficiency.
Ford claims that 70 percent of its lineup will have stop/start tech by 2017. The key to this massive proliferation is its new dual-battery system that combines a lithium-ion battery with a lead-acid one and regenerative braking. The setup works by harvesting braking energy and converting it to electricity. When the vehicle stops, the engine shuts off, but the Li-ion battery has enough juice to keep the accessories running. The engine starts up again as drivers take their foot off the brake. The layout would mean less wasted gas while idling. It's already available on Ford hybrids and is somewhat similar to the i-Eloop capacitor-based system from Mazda.
The bigger challenge is tuning the regenerative braking right. While hybrid drivers may be a little more adventurous, when it comes to getting a hang of regen braking, conventional buyers might not be so open-minded. The systems have a tendency to be a little grabby at first and then taper off at very low speeds. Ford needs to make sure it's just right to avoid turning off buyers.

2015 Ford F-150 shaves 700 pounds, adds 2.7-liter EcoBoost [w/video]

The Ford F-150 is one of the best selling vehicles on the planet. Considering that, one can imagine that when it comes time for a redesign, there are hardly any half measures. For its lucky thirteenth generation, Ford has gone all-in on the single most important vehicle in its portfolio, redesigning it from the ground up.
The big news is the F-150's new, lightweight, Atlas-inspired body. Ninety-three percent of that new body is made from a sort of aluminum alloy not unlike what the US military uses in its M2 Bradley fighting vehicles and Humvees, and it accounts for up to 70 percent of the F-150's 700-pound weight reduction. As a side benefit, the aluminum body should prove more resistant to dents and dings. Built Ford tough, indeed.
If you're wondering where the other 30 percent of that 700-pound weight loss went, 8.5 percent (60 pounds) came from the increased use of high-strength steel (up from 23 percent to 77 percent) in its ladder-box frame. Ford claims this steel is comparable to some of the heavy duty pickups used by its competitors, with a PSI rating of 70,000.
