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.

Ford expands door-latch recall to 156k more vehicles, nearly 550k total

Ford is being inundated with recalls as of late. Just days ago it called in over 590,000 cars for a variety of issues. Now, the Blue Oval has announced an expansion of its door latch campaign to cover an additional 156,000 vehicles in North America. Counting the original 389,585 cars, this has brought the total to 545,906. Under this expansion, the same models are affected, but Ford is broadening the coverage dates in some cases. The recall covers the 2011-2014 Fiesta, 2013-2014 Fusion, and 2013-2014 Lincoln MKZ; there are 456,440 units in the US, 50,681 in Canada, and 38,785 in Mexico in need of repair. In these vehicles, a door might not latch because of a broken pawl spring tab. Even if a passenger can successfully close it, the faulty part could unlatch while driving. According to Ford, there are two allegations of doors bounding back and hitting a person. There's also one possible accident from a door opening and striking another vehicle. Dealers will replace all of the latches to fix the problem. Related Video: MAY 1, 2015 | DEARBORN, MICH. FORD EXPANDS DOOR LATCH SAFETY RECALL IN NORTH AMERICA DEARBORN, Mich., May 1, 2015 – Ford Motor Company is expanding a safety recall regarding door latches to include approximately 156,000 more vehicles at the request of the National Highway Traffic Safety Administration, bringing the total to 545,906 vehicles in North America. The door latch in certain vehicles may experience a broken pawl spring tab, which typically results in a condition where the door will not latch. If a customer is then able to latch the door, there is a potential the door may unlatch while driving, increasing the risk of injury. Ford is aware of a total two allegations of soreness resulting from an unlatched door bouncing back when the customer attempted to close it, and one accident allegation when an unlatched door swung open and struck the adjacent vehicle as the driver was pulling into a parking space. Affected vehicles include certain 2011-14 Fiesta vehicles built at Cuautitlan Assembly Plant, Nov. 3, 2009 to May 31, 2013; certain 2013-14 Fusion vehicles built at Hermosillo Assembly Plant, Feb. 1, 2012 to May 31, 2013; certain 2014 Fusion vehicles built at Flat Rock Assembly Plant, April 12, 2013 to April 26, 2013; and certain 2013-14 Lincoln MKZ vehicles built at Hermosillo Assembly Plant, Feb. 1, 2012 to May 31, 2013. There are 456,440 vehicles in the United States and federalized territories, 50,681 in Canada and 38,785 in Mexico.

The 2015 Ford Mustang is not so mellow in yellow

When we first saw the 2015 Ford Mustang, much was made of its new, more expressive color palette, which includes the return of both yellow and orange in addition to a new grayish shade, Guard. At that time, we didn't have anything to look at but a few small scale models painted in the new colors - the only Mustangs on display were in Race Red.
For its auto show debut here at in the Motor City, Ford has trotted out a couple of as-yet-unseen shades, including the striking Triple Yellow shown above. The new shade marks a return to a paint color that enthusiasts have been clamoring for, and we must say, it looks excellent under the lights of Cobo Hall.
Stat wise, there are still a number of questions we have about the redesigned Mustang. None of the three engines have had official power figures published. The same goes for pricing information, although if any loose-lipped execs let something slip in Detroit, we'll be sure to let you know. Until then, have a look at the new Triple Yellow Mustang on display at the 2014 Detroit Auto Show.
