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 cranks up '32 Ford body production

If you're going to build your own hot rod, you'll want to start with a '32 Ford 5-Window Coupe. Favored by American servicemen returning from World War II, the '32 Ford remains the very icon of the hot rod to this day. The trouble is there were only so many of them made in the first place, and finding one today can be a challenge. That's where reproduction models come in.
The aftermarket is replete with companies that will sell you a fiberglass body in the form of a '32 Ford coupe, but quality can be hit or miss. So to help meet demand among hot rod builders and enthusiasts, Ford has teamed up with United Pacific Industries to offer officially licensed body shells.
Announced at the SEMA show in November, the '32 Ford 5-Window Coupe body is made from stamped steel according to original specifications from original machinery where possible or reproduced machinery built to the same original specifications where necessary. The bodies are ready to accept vintage powertrains or crate motors from the Ford Racing catalog, and join the 9,000 other parts offered in the Ford Component Sales catalog - including similar reproduction bodies available for the 1965-70 Mustang and 1940 Ford Coupe. From there, the proverbial sky's the limit.

Watch a Ford Bronco casually jump a McLaren 720S

Michael Cox can't stop jumping his classic Ford Bronco. He's jumped it on the beach. He's jumped it in the desert. He's jumped it at racetracks. Now he's jumped it in Hoonigan's backyard playground. Upping the ante on this one, he completed the jump while a modded McLaren 720S drifted underneath.  For those who don't know Michael Cox, he's a builder, racer, mad man extraordinaire who's worked with BMW and Porsche and specializes in off-road racing. Possibly more famous than the man is the vehicle he's known for driving, a custom-built Bronco that sports a cat-themed desert camo wrap.  Technically, this is not the first time Cox has visited Hoonigan and jumped his Bronco. But last time, the Bronco soared over nothing but tire crumbs and those tiny pebbles that get stuck in tread. This time, the stakes grew significantly, as a custom 720S drifted under the Bronco while it was in the air.  After a few donuts, Cox first tries a jump over a flatbed trailer. Once he easily clears that obstacle, Hoonigan brings the McLaren into the picture. Watch the video above to see a few crazy men show total disregard for the cost of a supercar.  This content is hosted by a third party. To view it, please update your privacy preferences.
