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 Mustang renders reveal look of the real thing

This is, according to the pony-car obsessed kids over at Mustang6G.com, the closest, most accurate rendering of the new, 2015 Ford Mustang to date. Artis Chazcron used a combination of Ford CAD images and information from assorted spy shots to assemble a fairly handsome car, albeit one that conforms to the tired cliché of being more evolutionary than revolutionary.
Now, it's very important to note that these are still speculative renders, and that they only represent the base car - that could explain the lack of the Mustang's vestigial side scoops, along with other, newer styling cues that Mustang6G seems to think will arrive on production models. Those items include a new, double-bubble roof, although the Mustang aficionados claim that even if it were present, it'd barely be visible from these angles.
The front end is pretty spot on, compared to what we've seen from earlier spy shots, while the tail, with its interesting light design is something new. The louvered taillights look quite different from the current version, obviously, though Mustang has gone the whimsical route with taillights before. Also, note the new rear diffuser uses an integrated reverse light and rear foglight, the latter of which is required for sale in Europe.
