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.

Project Ugly Horse alive and kicking at Road & Track

The hallways of the Autoblog campus are much quieter now that Zach Bowman has taken his prose, along with his welders, wrenches and hammers, over to the digital pages of Road & Track, but that doesn't mean our favorite project Mustang is gone forever. Project Ugly Horse is still coming along, and Zach has gifted us another update on his unfoxy Fox Body.
Last we saw of the Ugly Horse, Zach was strengthening up the '89 Mustang's chassis as he prepares to stuff the turbocharged, direct-injected EcoBoost engine of a Ford Focus ST under the hood. First things first, the old mill must go. Head on over to Road & Track to catch the latest chapter of Project Ugly Horse.

2014 Ford Fiesta Titanium

You might not be interested in owning a subcompact (B-segment) hatchback for $20,000. Let's be clear from the get go here: there are any number of reasonable arguments for staying away from the highest-content versions of these small cars. Ford's player in the B-segment arena is the newly updated 2014 Fiesta, and the Titanium trim represents the most luxurious instantiation of the model. We recently were loaned a Fiesta Titanium for a week, whose final sticker price hit $20,390, with navigation being the only standalone option added to the bottom line. By way of comparison, the most basic version of the all new, one-segment-up Mazda3 hatchback costs $19,740 with delivery and destination accounted for, and no options added on.
Hold on to that thought for a moment, we'll get back to it.
