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.

Ford, GM still doing new business with Takata amidst airbag crisis

Lengthy vehicle development times make it difficult for automakers to cut and run from the supplier. You might expect automakers to be fleeing any connection with beleaguered supplier Takata in the wake of the company's exploding airbag inflator crisis. After all, with a Senate hearing, pending lawsuit, plummeting stock value and demand for a national recall, the tier-one supplier isn't at its strongest right now. However, years of cooperation mean that automakers are standing by Takata, and necessity may be playing a role, as well. About 39 percent of Takata's business comes from airbags, and seatbelts make up another significant chunk of the operation too, says Bloomberg. The long-term relationships and lengthy vehicle development times make it difficult for automakers to cut and run from the supplier. "Takata has so much product breadth that I don't really see that they could just disappear," said AutoPacific analyst Dave Sullivan to Bloomberg. For example, Takata helped develop the unique front center airbag with General Motors in models like the Chevrolet Traverse and Buick Enclave. Outside of safety tech, it is also a partner with Ford on the adaptive steering system available on the upcoming 2015 Edge. These long-lasting partnerships make change difficult now that there's a problem. According to Reuters, automakers claim it would take a year or longer to set up with a different supplier for replacement airbag inflators. Switching to a completely different part for the repairs might not be a viable option either, because of the engineering time needed. BMW is taking action, though. According to Reuters, the Bavarian brand is working with the supplier to move inflator production from Monclova, Mexico, to a Takata factory in Freiburg, Germany. The Mexican plant may be the source of some of the faulty parts. News Source: Bloomberg, ReutersImage Credit: Jens Meyer / AP Photo BMW Ford GM Safety Takata airbag recall

Ford Shelby GT350R, GT successor, F-150 Raptor and more rumored for Detroit debut

According to a pair of reports from Hearst's car mags, Car and Driver and Road & Track, Ford has a whole mess of good stuff on deck for the Detroit Auto Show in January. And it all sounds awesome. First, expect to see a hotter version of the Shelby GT350 in Detroit, likely called GT350R. Think of this as the already-hot Shelby with even more track-focused bits baked in – brakes, tires, aero, etc. Everything about the GT350 sounds great, so expect this R variant to be something seriously fierce. As R&T suggests, if the GT350 is the company's new Boss 302, the R is the Laguna Seca. But that's not even close to the biggest news. Road & Track believes a proper Ford GT replacement will debut in Detroit – a road-going version of the Le Mans GTE-class car the Blue Oval is working on for 2016. We've heard about this before, but having the street-legal car debut in Detroit would be absolutely huge news. The performance story continues, though, with R&T suggesting that the next-gen Ford F-150 Raptor will bow in Detroit. Details are scarce about what, exactly, the aluminum-bodied desert stormer will hold, but we expect good things. Finally, Ford's hot hatches might make some news in the Motor City, too. Car and Driver seems to think the all-wheel-drive Focus RS will bow in The D, and that an updated version of the Fiesta ST will also show its face. Road & Track, meanwhile, believes the Focus RS showing will be saved for a European auto show – think Geneva – and our gut feeling is to agree with the R&T theory. All of these rumors point to Ford officially announcing its dedicated performance division – like Mercedes-AMG, BMW M, and so on. We've heard reports of a new, global performance brand from the company already, with the name 999 thrown out as a possibility. In any case, if these rumblings prove to be true, there's going to be a ton to drool over from Ford in January. Stay tuned.
