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.

U.S. auto sales in April expected to drop despite big discounts

DETROIT — U.S. auto sales in April likely fell nearly 8 percent from the same month in 2017 despite big discounts for consumers, industry consultants J.D. Power and LMC Automotive said on Thursday. For much of the past two years, the discounts offered by automakers have remained at levels that industry analysts say are unsustainable and unhealthy in the long term. April U.S. new vehicle sales will likely be about 1.31 million units, down from 1.42 million units a year earlier, the consultancies said. The forecast was based on the first 17 selling days of April. Automakers, including Ford and Fiat Chrysler Automobiles, will release April U.S. sales results on May 1. Earlier this month, No. 1 U.S. automaker General Motors said it will stop reporting monthly U.S. sales because the 30-day snapshot does not accurately reflect the market. GM will instead issue quarterly sales reports. U.S. new vehicle sales fell 2 percent in 2017 to 17.23 million units after hitting a record high in 2016. Sales are expected to drop further in 2018 as interest rates rise and more late-model used cars return to dealer lots to compete with new ones. LMC expects full-year 2018 U.S. new vehicle sales to come in at around 17 million units. "Uncertainty and unfavorable factors appear to be mounting for autos, including a volatile stock market, rising interest rates, rising oil prices and potential trade roadblocks," Jeff Schuster, LMC's head of global vehicle forecasts, said in a statement. The seasonally adjusted annualized rate of sales for April will be 16.6 million vehicles, down more than 2 percent from 17 million units in April 2017, the consultancies said. Retail sales to consumers, excluding lower-margin fleet sales to rental agencies, businesses and government, were set to decline about 9 percent in April. The level of consumer discounts, which can erode profit margins and undercut resale values, "remains the larger concern," the consultancies said. The average discount was $3,698, up $187 from April 2017. Discounts on trucks and SUVs were up $426, but down $226 on passenger cars.
