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 highlights new F-650 and F-750 with full-size Tonka show truck [w/videos]

Who among us hasn't been tempted by the prospect of buying a big yellow truck and painting the name Tonka along the side? Well apparently there were some folks over at Ford who were just as tempted, only they actually had the means to make that childhood fantasy a reality in the form of the truck you see here. Revealed at the NTEA Work Truck Show this week in Indianapolis, this Tonka show truck stands nearly 10 feet tall. It's painted bright yellow, just like the one you played with in the sand box (and probably still would given the opportunity and maybe no one else looking) and has a blacked-out nose treatment and special graphics. As you can see, it's also equipped with a working dump bed, and has a truly staggering 33,000-pound gross vehicle weight rating, built to showcase the Blue Oval's new line of medium duty trucks. Of course "medium duty" is a relative term, and the new F-750 is clearly a heavier piece of machinery than the company's own Super Duty pickups, but they're lighter-duty than a proper big rig. The new 2016 Ford F-650 and F-750 are just as tough as the models they replace, but they're now quieter and more comfortable to use. In fact, Ford says its 6.7-liter Power Stroke V8 diesel is now 25-percent quieter inside the cabin at highway speeds, 45-percent quieter at idle and 35-percent quieter standing outside in front of the grille. Ford notes that it's the only medium-duty truck manufacturer that makes its own engines and transmissions. That Power Stroke diesel comes with 270 horsepower and 675 pound-feet of torque as standard, but can be upgraded to 300 hp and 700 lb-ft or all the way up to 330 hp and 725 lb-ft. Commercial buyers will also be able to choose between Regular, Super and Crew Cab models with a straight-frame, dock-height or tractor-towing frames, meaning that whatever it is you've got to haul, chances are high that the new Ford F-650 and F-750 can be set up to get the job done.

USPS releases hot rod stamps to speed up your delivery

After one of the worst winters in recent memory for much of the country, summer is finally here. It's time to drop the top, open the sunroof or at least put down the windows and take a long drive. The United States Postal Service is celebrating the season's sun in automotive style with two new hot rod Forever stamps.
Both stamps depict classic '32 Ford hot rods. One shows the car from the front at a low angle in red (pictured above), while the other depicts the car from the back in black with flames running down the side.
To introduce the new stamps on their first day of availability, the USPS went straight to the source at the National Street Rod Association Street Rod Nationals in York, PA. They were unveiled by Postmaster General Patrick Donahoe, Car Crazy host Barry Meguiar and NSRA Special Events Director Jerry Kennedy.
