Ford sued over alleged 3.5-liter EcoBoost defects

Three Ford owners from Ohio have filed a lawsuit against the automaker over defects that they allege exist within the company's twin-turbocharged 3.5-liter V6 EcoBoost engine. Automotive News reports that the lawsuit claims the engine "contained serious latent design, manufacturing, or assembly defects." Those defects, the suit claims, cause the vehicle to shake, misfire and lose power quickly.
Two of the plaintiffs, a married couple, own a 2010 Ford Taurus SHO, and allege they experienced a loss of power and stalling, while the third, an F-150 owner, claims he lost power while accelerating. In addition to the Taurus SHO and F-150, the 3.5-liter V6 EcoBoost engine is also available in the Ford Flex, Explorer Sport and Lincoln MKT and MKS. Other three- and four-cylinder EcoBoost engines are not included in the suit. There have been no recalls associated with 3.5-liter V6 engine, and the National Highway Traffic Safety Administration is currently not investigating the matter.
The plaintiffs, however, claim Ford has known about the problem, citing several technical service bulletins issued to dealers of the F-150 that suggest possible fixes. Ford had no comment for Automotive News, saying that it's yet to review the lawsuit, which was filed last Friday in Columbus, OH.

2015 Ford Expedition

While the tide of bigger-is-better SUVs has been in recession since, well, the recession, fullsize utes are still very much with us. Conservative creatures that have been loathe to evolve, fullsize SUVs nonetheless remain enduringly popular among large families, livery customers, and anyone with lots of friends, relatives, and toys to tug around. With respect to Toyota and Nissan, the only players that really matter in the segment are the new-for-2015 Chevrolet Tahoe/Suburban, the GMC Yukon/Yukon XL, and this truck: the Ford Expedition, the latest evolution of which we just drove for the first time at a press preview in West Virginia.
Unlike the General Motors utilities, the standard Expedition and the long-wheelbase Expedition EL are not all-new, but rather are heavily refreshed versions of the same basic truck Ford started selling way back in 2007. The front fascia is where most of the exterior update happens for 2015, with a new three-bar grille design, halogen projector headlamps, and new bumper design with available LED foglamps. Despite all the new bits, the facelift breaks exactly zero ground in terms of design; in fact, it already looks dated, and will only look older once the macho 2015 F-150 bows later this year. Even less has changed out back, where the tailgate gets a wide chrome band spanning the taillamps and a new chrome exhaust tip. Other exterior changes are generally limited to colors and an all-new wheel lineup that includes a gleaming set of six-spoke 22-inch polished wheels on high-end models.
Speaking of high-end models, a new Platinum trim is positioned above the cowboy-spec King Ranch model for 2015. Both the Platinum and King Ranch get their own color combos and exterior trim finishes (satin metal for the Platinum, chrome everywhere and ginormous badges for the King Ranch) and posh, leather-lined interiors with their own aesthetic. The Expedition family also now includes a price-leading XL model, as well as XLT and Limited grades.

The tricky business of octane, power, and MPG

Given tepid green-car sales numbers this year, consumers in the US aren't making the transition away from internal combustion engines too quickly. Regulations are still mandating cleaner emissions, though. In addition to downsizing and turbocharging, there's growing consideration about moving to higher-octane fuel to improve overall efficiency. In a new report, engineers at FCA, Ford and General Motors Powertrain are showing that it could work, too. The major advantage to higher-octane fuel is that it supports higher compression ratios. That in turn can lead to more power from burning the same amount of gas. "Higher ethanol content is one available option for increasing the octane ratings of gasoline and would provide additional engine efficiency benefits for part and full load operation," the researchers write in the study's abstract. The authors even think it could be possible to update some modern vehicles' engine calibration to be optimized for the better gas. While the benefits are there, we still have a long way to go before higher-octane fuel becomes a national standard. According to Green Car Congress, 87 percent of the gas sold in the US is regular grade 87-octane. Meanwhile, premium 91-93 octane makes up just 10 percent. The various grades of fuel illuminate even more annoyances with the current system. For example, Ford generally recommends 93-octane for EcoBoost engines, and the power outputs that the company publishes are based on using it. However according to Green Car Reports, such premium gas is very difficult to find in some regions of the US, especially along the West Coast. The powertrains still run on lesser grades but with lower power output. The researchers' discussion of possibly increasing ethanol in gas also comes during a heated debate on the substance. The current administration is pushing for less of the corn-based fuel in the coming years. Although, several presidential hopefuls might be favor of reversing that course.
