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.

Lower gas prices mean there are excellent deals on green cars right now

The phenomenon was big enough to make news in 2006, then in 2008, in 2011, in 2012, in 2013, and again last year: a big move in gas prices means a big move in alternative-fuel-vehicle sales. True Car's TrueSavings report, which averages transaction prices across the country to figure out what people are paying compared to MSRP, shows that electric cars and hybrids are ripe for excellent savings right now. The Ford Focus Electric presents the greatest disparity, with the average transaction price of $25,168 representing a 16.1-percent saving off its $29,995 MSRP. The Kia Optima Hybrid and Toyota Prius also snagged spots in the top five, with the Kia offering a 10.7-percent discount and the Toyota a 10.1-percent discount. One hybrid managed to show up among the top five lease offers, too: the Lincoln MKZ Hybrid is just $315 a month for 36 months after $3,875 down in some markets. Alt-energy vehicles got bumped out of the top five finance deals, however. That was dominated by light trucks and, oddly, two subcompacts. The press release below has more details. TrueCar finds hybrids, EVs top list of best savings in January Gasoline price plunge = savings for consumers on alternative fuel vehicles SANTA MONICA, Calif., Jan. 15, 2015 /PRNewswire/ -- Ford's Focus Electric hatchback, which sells at an average of 16 percent off MSRP, tops January's list of best savings on new vehicles, according to TrueCar, Inc. (NASDAQ: TRUE), the negotiation-free car buying and selling platform. The "TrueSavings" monthly report analyzes current transaction prices and identifies opportunities for consumer savings. "Fuel savings are not top of mind to many consumers right now, and that makes this a great time to buy a hybrid or electric vehicle," said John Krafcik, president of TrueCar. "With gasoline prices now averaging just $2.10 per gallon, and vehicle preferences tied so closely to short-term gasoline prices, automakers are heavily discounting their most fuel-efficient cars to clear inventories." Toyota's Prius, the world's best-selling alternative fuel vehicle for more than a decade, also makes January's list of best savings. Customers who purchase a Prius Two model this month can save 10 percent off the hybrid car's $25,025 MSRP. "Gasoline prices and vehicle type preferences are strongly related, and this relationship is cyclical in nature," said Krafcik.

Next Ford F-150 delayed for aluminum body panel issues?

The timetable for next-generation Ford F-150 may be in trouble if a report from The Truth About Cars is true. The next F-150 is slated to make extensive use of weight-saving aluminum in its body, but the aluminum alloy provided by suppliers hasn't met Ford's requirements in the earliest phases of pre-production, according to the report.
The F-150 represents a huge portion of Ford's profits and is the best-selling truck in the US, even in the face of increased pressure from cross-town rivals General Motors and Ram. While the current truck is treading water against its competition, we'd be lying if we said the F-150 weren't growing quite long in the tooth.
If production of the next-generation of the Ford cash cow, said to be based on the Atlas Concept from the 2013 Detroit Auto Show (pictured above), is delayed, it could be bad for Ford. Production at Ford's Dearborn Truck Plant is already set to be delayed six to ten weeks, missing an internal on-sale deadline of Memorial Day.
