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.

You'll have to apply to purchase a Ford GT

With the 2017 Ford GT rumored to cost around $400,000, an anonymous insider says that the company is taking a very exclusive approach in deciding who gets to own these supercars. The Blue Oval isn't forgetting its roots, though, and some current customers might get the first crack at the coupe's extremely limited production numbers. Reddit user 3031983 claims to work at a dealer and have access to an internal Ford website, which is where this info comes from. The ordering process for the latest GT begins in early 2016, and any interested buyers need to file an application with Ford first. Anyone can submit the request, but Ford is giving top priority to current GT owners. Once selected, customers will be walked through the personalization process and will eventually complete the purchase through a dealer certified to sell the GT. Autoblog reached out to Ford, and the company confirmed that all of the user's details are accurate. The concierge-style service certainly isn't uncommon with other high-end vehicles, though. It's also understandable that the Blue Oval would want to work closely with wealthy, enthusiast buyers, rather than just shipping its supercar off for dealers to sell. The user also reports that Ford is limiting global production of the GT to just 250 units a year, which the company confirms. That makes the Blue Oval's supercar truly exclusive for its early life. For comparison, Ferrari only built 499 LaFerraris, and there were 918 Porsche 918 Spyders. Related Video:

National Geographic Channel balances Ford F-150 on four coffee mugs

Proving that there is still something to be learned on television these days, National Geographic Channel recently introduced a new series called Duck Quacks Don't Echo. On the first episode of this science/comedy show, host Michael Ian Black proposes the idea that a truck can be supported with a ceramic coffee mug under each wheel - yes, he says that the entire weight of a truck can be balanced on just four coffee mugs.
Looking to find out whether this is fact or myth, the show uses a regular cab Ford F-150, weighing in at 4,800 pounds, and four average coffee mugs. Lowered onto the mugs, the idea is quickly put to the test. Can the cups hold up under 4,800 pounds? If so, what, exactly, would it take to break them? Scroll down below to find out.
