Ford auctioning off F-35-themed 2015 Mustang for charity

Ford's been a supporter of EAA AirVenture, a huge, annual air show held in Oshkosh, WI, for several years now, with one of its most notable contributions being a modified Ford Mustang, designed to look like one of America's great fighting aircraft. There was an SR-71 Mustang, based on the legendary spy plane, a Red Tails edition, which honored the ground-breaking Tuskegee Airmen of World War II, as well as Blue Angels and Thunderbird Mustangs, based on America's two great military aerial demonstration teams.
Each car is auctioned off, with all proceeds going to the EAA Young Eagles program, which introduces kids to the joy of flight. For the 2014 AirVenture, which runs from July 28 to August 3, the one-off pony car is based on the new-for-2015 Mustang, and America's latest fighting aircraft - the controversial F-35 Lightning II.
The unique Mustang sports titanium paint scheme, with both glossy and matte sections, as well as yellow-and-blue trim and decal elements inspired by CF-1, the first F-35 test plane. A carbon-fiber front splitter and rear diffuser add some visual eye candy, while the interior boasts a set of Recaro seats. Ford also opted to fit unique wheels and a brawnier rear spoiler, to tie everything together.

American automakers fall in latest Fortune 500 rankings

Not that it means anything beyond bragging rights, but if you're fixated on the positions of domestic automakers on the annual Fortune 500 list, both General Motors and Ford are still on it but they've slipped a couple of notches. The list ranks American companies and they're ordered solely by revenue. GM, fifth last year, came in seventh, while Ford fell from ninth to tenth even though both companies saw small gains in annual revenue.
GM's $152.3 billion in revenue was less than a third of that of the first company on the list: Wal-Mart, which regained the title from Exxon Mobil. Berkshire Hathaway and Apple are the firms that moved GM down. Ford, displaced by energy company Valero, had $134.3 billion in revenue.
On a side note, profitability isn't a factor, but both GM and Ford were down in this year's list compared to last year's: GM declined from $9.2 billion to $6.2 billion, Ford fell from $20.2 billion to $5.6 billion. If profits were included, Exxon Mobil would probably still be king: although the energy company made almost $20 billion less in revenue than Wal-Mart's $469.2 billion, it posted $44.9 billion in profit compared to Wal-Mart's $17 billion.

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.
