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.

Rising aluminum costs cut into Ford's profit

When Ford reports fourth-quarter results on Wednesday afternoon, it is expected to fret that rising metals costs have cut into profits, even as rivals say they have the problem under control. Aluminum prices have risen 20 percent in the last year and nearly 11 percent since Dec. 11. Steel prices have risen just over 9 percent in the last year. Ford uses more aluminum in its vehicles than its rivals. Aluminum is lighter but far more expensive than steel, closing at $2,229 per tonne on Tuesday. U.S. steel futures closed at $677 per ton (0.91 metric tonnes). Republican U.S. President Donald Trump's administration is weighing whether to impose tariffs on imported steel and aluminum, which could push prices even higher. Ford gave a disappointing earnings estimate for 2017 and 2018 last week, saying the higher costs for steel, aluminum and other metals, as well as currency volatility, could cost the company $1.6 billion in 2018. Ford shares took a dive after the announcement. Ford Chief Financial Officer Bob Shanks told analysts at a conference in Detroit last week that while the company benefited from low commodity prices in 2016, rising steel prices were now the main cause of higher costs, followed by aluminum. Shanks said the automaker at times relies on foreign currencies as a "natural hedge" for some commodities but those are now going in the opposite direction, so they are not working. A Ford spokesman added that the automaker also uses a mix of contracts, hedges and indexed buying. Industry analysts point to the spike in aluminum versus steel prices as a plausible reason for Ford's problems, especially since it uses far more of the expensive metal than other major automakers. "When you look at Ford in the context of the other automakers, aluminum drives a lot of their volume and I think that is the cause" of their rising costs, said Jeff Schuster, senior vice president of forecasting at auto consultancy LMC Automotive. Other major automakers say rising commodity costs are not much of a problem. At last week's Detroit auto show, Fiat Chrysler Automobiles NV's Chief Executive Officer Sergio Marchionne reiterated its earnings guidance for 2018 and held forth on a number of topics, but did not mention metals prices. General Motors Co gave a well-received profit outlook last week and did not mention the subject. "We view changes in raw material costs as something that is manageable," a GM spokesman said in an email.
