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.

These horribly misguided front-drive design studies nearly became the Mustang

As we eagerly await the unveiling of the all-new sixth-generation Mustang, Ford has been giving us some great information over the past few months showing what has gone into shaping its venerable pony car. As many changes as the Mustang has gone through in its 50 years, though, it appears the fourth-gen model played a decisive and pivotal role in the car's future.
As is part of Mustang lore, the front-wheel drive Ford Probe was originally developed as a next-generation Mustang in the Eighties before cooler heads prevailed. The Blue Oval has just released a handful of images showing how bad things could have been - including a full-scale clay model of a front-wheel-drive Mustang (shown above). Fortunately, the FWD Mustang plan was scrapped and Ford went to work designing a rear-wheel-drive replacement for the Fox Body Mustang, with three design studies making it far enough to become full-scale models. These include the soft "Bruce Jenner" Mustang, the over-the-top "Rambo" Mustang and the middle-ground "Arnold Schwarzenegger" Mustang, which finally became the basis for the 1994 'Stang.
By early 1991, the design language of the fourth-generation Mustang had been worked out, and the rest, they say, is history. Scroll down for the fascinating press release telling the story of the fourth-gen Mustang, and be sure to check out the gallery of horribly misguided sketches and various design studies that were all on the table in the late 1980s.

Ford shutters Genk assembly plant in Belgium

Ford has become the latest automaker to close one of its European assembly plants. The facility in question is located in the Belgian city of Genk and has been in operation since the early '60s when it started building the Taunus, Ford's first mass-produced, front-drive model. As part of the plan first announced over two years ago, the Genk Body & Assembly Plant is now closing its doors after half a century in the business and over fourteen million vehicles built. Although the plant itself employed some 5,000 workers, once you take into account the suppliers built up around the plant, the overall impact on employment in the area edges closer to 12,000. Genk Body & Assembly had until recently been tasked with producing the Mondeo sedan (which in its current iteration we know as the Fusion) as well as the S-Max and Galaxy minivans. Production of the Mondeo shifted in 2013 to the company's plant in Valencia, Spain, which also handles the Kuga crossover and Transit Connect cargo van, and will soon take over the minivans from Genk as well. The move follows a similar decision undertaken by General Motors to close the Opelwerk plant in Bochum, Germany. It also reflects a scaling down of automobile production in Belgium specifically: although Audi still manufacturers in Brussels and and Volvo in Ghent, Opel closed its plant in Antwerp in 2000 and Renault ceased production in Vilvoorde back in '97. However Ford still maintains its famous proving ground half an hour to the north in Lommel, Belgium.
