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 drops Focus RS teaser ahead of Feb 3 reveal

Ford is trying to get us hyped for the unveiling of the latest Focus RS on February 3 with this new video teaser. The clip showcases the hot hatch doing some big slides in the wet and dry during testing in Europe and the US, and it definitely makes us even more curious about what the Blue Oval has in store with the RS. Even in this short teaser, Ford continues to dress the more aggressive nose of the Focus RS in camouflage, like the previous test cars. Unfortunately, what's going on under all of that concealment remains a bit of a mystery. Rumors suggest the RS likely uses a tuned version of the Blue Oval's 2.3-liter turbocharged four-cylinder estimated to make between 325 and 350 horsepower. A speculated torque-vectoring all-wheel-drive system should keep fears of torque steer at bay, and larger brakes on the test mules indicate that bringing it all to a halt shouldn't be a problem, either. We do know that the hotter Focus will be among the "more than 12" vehicles that the new Ford Performance division will develop through 2020, and the RS will come to the US for the first time. However, US-spec RS models will likely be imported from Europe, which will keep numbers here low and will mean prices estimated to be around $30,000 or more. Until the official specs become available, at least enjoy watching this hot hatch's ability to slide.

Fallon picks Ford F-150 King Ranch, launches dealership contest

New truck! Jimmy Fallon of The Tonight Show has been searching for the perfect new truck for a few weeks now, soliciting help from all corners in the process. Last night, Fallon made the announcement that the Ford F-150 King Ranch - in all of its cowboy glory - had been picked as his big winner.
To add some more spice to a storyline that now dips deeply into the realm of the advertorial, Fallon also announced a contest to see which Ford dealership would get the privilege of selling him the King Ranch. Dubbed "Fingers on a 4x4" The Tonight Show has invited 10 dealer reps from around the country to keep their hands on Jimmy's F-150 for as long as possible. Last salesperson standing wins.
Watch Fallon make his pick and introduce the dealer reps below, and be sure to click on the second video for a live-streaming feed of Fingers on a 4x4 in action (the contest seems to be going strong).
