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.

2015 Ford F-150 begins rolling off line at second factory

Ford needs more F-150s. Yeah, we just told you that a few days ago. The Blue Oval is reporting that its trucks are spending a mere 18 days on dealer lots, following a January that was the truck's best month in over a decade. Considering both of those facts, the timing is perfect for Ford to ramp up production of its all-aluminum truck by bringing its Kansas City, MO factory online. KC Assembly has been building F-150s for decades, and completed a $1.1-billion expansion to accommodate the all-aluminum 2015 truck (as well as for work on the Transit van). Similar to what was done at Ford's Dearborn, MI factory, the Blue Oval spent 13 weeks upgrading the plant's body shop, paint shop and a road-test course. Over 900 jobs were added as part of the update. Combined with the equally upgraded plant in metro Detroit, Ford can build 700,000 trucks per year. "The all-new F-150 has surpassed our expectations – setting new standards for fullsize truck capability, technology and efficiency," Joe Hinrichs, Ford's Americas president said in a statement. "With production starting at Kansas City Assembly, we are better poised to start meeting growing customer demand for our pickup." Scroll down for the official press blast from the Blue Oval.
