NHTSA closes rollaway investigation into 1.56M Ford SUVs

It's taken four years of study, but the National Highway Traffic Safety Administration has finally closed the books on its investigation into rollaway accusations surrounding 1.56-million Ford SUV models.
The probe, which centered on the 2002-2005 Ford Explorer, 2002-2005 Mercury Mountaineer and 2003-2005 Lincoln Aviator, ends without the federal agency calling for a recall. According to The Detroit News, the investigation was closed due to a "low number of complaints" - NHTSA documented 180 such complaints that resulted in 14 crashes and six minor injuries, but the number of incidents have been slowing. The suspected defect rate for the trucks' automatic transmissions was found to be 4.4 per 100,000 units, and the brake-shift interlock mechanism failure rate was judged to be even lower at 3.4 per 100k.

Ford, Alcoa announce next generation of aluminum lightweighting for F-150

Ford likes what it has seen with the use of aluminum in its world-beating F-150 pickup trucks. Now, the Blue Oval is working with Alcoa to use that company's Micromill material to increase the amount of aluminum in Ford vehicles. In fact, Ford will start using Micromill on 2016 model-year F-150s later this year, and will double the material's use in 2017. The purpose, as you might suspect, is light weighting, which allows Ford to boost towing capacity while adding as little weight as possible. Ford will be the first automaker to use Micromill, and will use it in both structural components and exterior panels. Micromill's rolling-mill system cuts the time it takes to turn molten metal into coil to 20 minutes from about 20 days. Already, Ford has had positive results by using aluminum on its leading pickup truck model. In April, it was announced that the 2015 Ford F-150 achieved a five-star Overall Vehicle Score in the National Highway Traffic Safety Administration's testing. Safety features like inflatable seat belts, adaptive steering columns and a forward collision warning system helped matters. General Motors may have taken note of those results, even after running an ad campaign touting its continued use of steel over aluminum. Last month, GM said it would sink $877 million into its Flint, MI, truck factory. Reuters said much of the expense was to convert many of the bodies for models like the Chevrolet Silverado and GMC Sierra pickups into aluminum. You can take a look at Ford's press release below. Ford Motor Company and Alcoa Inc. are collaborating to produce next-generation automotive aluminum alloys that are more formable and design-friendly. Ford will use Alcoa's Micromill® material in multiple components on the 2016 F-150 – becoming the first automaker to use the advanced automotive aluminum commercially. The companies entered into a joint development agreement to collaborate on next-generation aluminum alloys for automotive parts using Micromill™ technology. ''Light-weighting enables us to design vehicles with great customer attributes – like the F-150, which can tow more, haul more, accelerate quicker and stop faster than the previous F-150, and is more fuel-efficient than ever," said Raj Nair, Ford group vice president and chief technical officer, Global Product Development.

Watch these videos of an NHRA racer's bodywork blowing off into a crowd

Just a few months ago, fan safety at racetracks was a hot topic following the last-lap NASCAR Nationwide Series crash at Daytona that sent large pieces of racecars into the grandstands injuring 33 fans. Now, a freak incident at a National Hot Rod Association event resulted in a drag racer's bodywork flying into the crowd at the NHRA Four-Wide Nationals in Charlotte over the weekend. The carbon-fiber body of Robert Hight's Ford Mustang funny car blew off toward the end of a run when his engine exploded, but fortunately, the two fans evaluated after the incident were later released without serious injury.
As you can see in the image above, the body flew high into the air before landing on a walkway in front of the grandstands, a bit of happenstance that likely gave most fans enough time and space to move out of the way. Scroll down to watch a couple of videos showing what happened, including one from a fan's perspective that also reveals what appears to be part of the body's metal bracing landing dangerously close to the crowd.
