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's J Mays feels vindicated by Fusion reception

It's hard to think back now, but the same man overseeing the design of the 2013 Ford Fusion also presided over a rather lackluster period in Ford design, highlighted by vehicles like the Five Hundred and Freestyle. With the redesigned Fusion receiving high praise, J Mays tells Automotive News that he feels vindicated from criticisms suggesting he's not a daring enough designer.
When Mays took over as lead of design in 1997, he admits to having quite an ego ("My head would barely fit through the door some days. I've long since gotten over myself") and the workload to match. With the Blue Oval's portfolio full of premium brands like Aston Martin, Jaguar, Land Rover and Volvo at that point, along with the bread-and-butter Ford, Lincoln and Mercury models, Mays certainly had quite the challenge.
It was in the mid-2000s that Mays took over just the premium brands, and took on the new title of Chief Creative Officer. At the time, Mays endured some criticism for looking backwards to retro styling, rather than setting a new standard for American car design - criticism that Mays says he is free from with the all-new Fusion.

Feds looking into Ford Explorer exhaust leak complaints

There may be a burgeoning problem with exhaust leaks in the 2011-2014 model year Ford Explorer. The National Highway Traffic Safety Administration is examining multiple complaints of a gasoline smell in the cabin of these SUVs. However, the exact cause of this problem is still unknown.
"The agency is reviewing all available data and will take appropriate action as warranted," said a NHTSA spokesperson in an email to Automotive News. Owners seem to generally complain on the regulator's website of the smell entering the cabin through the air vents. At this time, the government organization has not yet opened an official investigation into the problem, though. When it does begin inspecting vehicles, NHTSA posts a detailed breakdown of its public data online.
Similar problems have been reported about the Explorer in the past, though. In 2013, Ford issued a recall for the 2013 model year of the SUV due to a fuel leak that could cause drivers to smell a gasoline odor and repaired them again later for another possible leak. In response to Autoblog's questions, Ford responded via email: "We are not aware of a NHTSA investigation. We are currently reviewing the case and in the event that any action is required, we will address it promptly."
