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.

Bomb threat closes Ford Romeo Engine Plant [UPDATE]

UPDATE: Ford has released the following statement about what's happening at the factory: "The Ford Romeo Engine Plant was reopened at 12:47 PM after law enforcement investigated and cleared the site. The afternoon and evening shifts are expected to report at their usual start times. Further questions on the investigation by law enforcement can be directed to the Romeo Police Department." Due to a bomb threat, Ford has evacuated its Romeo Engine Plant, and law enforcement is on the scene. According to the Detroit News, police with bomb-sniffing dogs are searching the building, which covers over 2 million square feet. Ford spokesperson Mike Moran wouldn't disclose to Autoblog how the threat was received but said that it came in between 7:00 a.m. and 7:30 a.m. Eastern on July 30. "The day shift was sent home," he said. According to the Detroit News, the second shift was also asked not to come in. About 500 people work at the plant, Moran indicated. At this time, Moran said that there hadn't yet been an update from law enforcement whether anything had been found in their search. The Romeo Police Department confirms to Autoblog that it's handling the investigation. However, the authorities wouldn't comment further about what is happening at the plant at this time.

How and why Ford is rolling out Vignale in Europe

We know that Ford is positioning the new, upscale Vignale brand in Europe to fill a niche market of customers who want a bit more luxury, a lot more service and the same reliability and dependability that a non-Vignale Ford offers. But so far, we've been in the dark regarding how the Blue Oval will sell Vignale vehicles, how many of them will be created, and what the new sub-brand has in store for the future.
Gaetano Thorel, Ford's European marketing head, recently was interviewed by Automotive News and shared details about Ford Vignale. Thorel says, "The Vignale trim line will be priced like an ST model but attract a completely different type of customer." Specifically, he says it will attract customers in the upper 15 percent of the price band who don't want a performance-oriented ST model. He adds that Vignale cars will be about 10 percent more expensive than Titanium-trim cars. About 500 of Ford's European dealers will sell Vignale Fords, Thorel says, "in areas that make sense." The automaker expects 10 percent of its European sales to be Vignale cars, which equates to about 5 percent of its global sales. When asked if there are any other Vignale models planned beyond the Mondeo, Thorel said, "There is nothing written in stone yet."
