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.

Supercars for the win | Autoblog Podcast #515

Some days at Autoblog are better than others. And in this episode, we talk about those days. Specifically, the days where we get to drive supercars. Mike Austin, Greg Migliore, and Alex Kierstein join up in this episode to talk about driving the McLaren 720S, Ford GT, and Porsche 911 GT3. We also drove some less-super, but still notable cars that we talk about at the top of the show. And as always, we play the game Spend My Money where we get to tell readers what we'd do if we were them. We had a lot of fun with this one, we hope you enjoy listening to it. The rundown is below. Remember, if you have a car-related question you'd like us to answer or you want buying advice of your very own, send a message or a voice memo to podcast at autoblog dot com. (If you record audio of a question with your phone and get it to us, you could hear your very own voice on the podcast. Neat, right?)

1914 Ford Model T at Historic Greenfield Village | AutoblogVR

We drive all of the newest and most sophisticated cars, but a 102-year-old Ford is one of our recent favorites. Senior Editor Alex Kierstein headed to historic Greenfield Village in Dearborn, MI, to learn to drive a Model T in the latest AutoblogVR segment. Kierstein picks up the Model T fairly quickly, despite its controls. Though they were designed more than a century ago to be simple and easy to use, driving a Model T is complicated and counter-intuitive to the modern motorist. But by the end of his lesson, Kierstein has it all figured out and is enjoying himself. In our other new segment, Detroit Manufacturing, Senior Editor Greg Migliore showcases the city''s industrial might. He tours a modern Fiat Chrysler factory that churns out Dodge Durangos and Jeep Grand Cherokees and then wanders the ruins of the mythical Packard Plant. There's also some tasty and unexpected twists in this VR episode. Each week, new episodes will launch on the AutoblogVR App. We'll preview them here on Autoblog, but for the full immersive experience, head over to the app, which you can download for free from the App store and Google Play.
