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 says 70% of its models to get stop-start by 2017

Ford is following up on a report we posted a few weeks back that the Blue Oval would be adding stop-start technology to its entire model range. Now, the Dearborn-based automaker has announced that the fuel-saving feature would be available on 70 percent of the company's range by 2017.
Ford claims the technology will improve fuel economy by around 3.5 percent, although its actual effect will vary based on how the owner drives - apparently up to a 10-percent improvement is possible for those who sit in heavy traffic (Los Angelenos, this means you). The latest recipient of the technology is the updated 2014 Ford Fiesta with the company's three-cylinder EcoBoost powerplant.
Part of the reasoning for the new addition has to do with cost. Ford claims the tech is affordable and easy to implement. "Simply put, Auto Start-Stop helps customers use less fuel, which is an important component of Ford's Blueprint for Sustainability," Ford's global powertrain vice president, Bob Fascetti, said.

2015 Saleen 302 Black Label Mustang unveiled with 730 horsepower

The last time Saleen made these pages it was to report that the firm was out of money. However, just before that announcement, the tuning specialist told us about the three Saleen 302 Mustangs it was developing at three levels - White Label, Yellow Label and Black Label, with those latter two trims to put out 640 horsepower and 565 pound-feet of torque. Well, the Black Label is here - don't let the California Sunset paint fool you - and it's more powerful than planned, with 730 hp and 600 lb-ft blasted out of a 5.0-liter Coyote V8 hooked up to a twin-screw supercharger. Saleen says it's the most powerful, refined, and advanced Mustang it has ever built. Keeping all that power on the road is the increase in downforce that comes from a body that's been extended one inch in front and two inches in the back, and the wing suspended over the decklid. The stock suspension is refitted with Saleen S4 springs, shocks, swaybars and bushings, and the 20-inch wheels on 275-section rubber hide 15-inch dimpled rotors. The interior gets the requisite frills in leather and contrasting stitches, as well as new gauges and badging. It'll take $73,214 to open the door, but just $2,015 to put down a deposit.

To round out their fleet, Saleen pulled out all the stops and developed one of the best Mustangs to date. This car is set to change the way pony cars are looked at from here on out. At a one-of-a-kind event in Downtown LA, Saleen raised the curtain on the latest pony car out of their Corona, CA headquarters. "Since I started building cars in 1984 my goal has always been to go above and beyond where anybody has been before", said Steve Saleen. "This will by far be the most refined and advanced Mustang we have built to date." With over 30 years of experience in both racing and manufacturing vehicles, it was only a matter of time before Saleen built a Mustang as comprehensive and technologically advanced as the 2015 302 Black Label. Power Saleen combined the reliability and potency of the 5.0L Coyote motor with a twin-screw supercharger. The pair produces the most power from a production Mustang yet at 730 horsepower and 600 lb-ft of torque on 91 octane gas.
