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 reveals 345-horsepower output for new Focus RS [w/video]

When Ford revealed the new Focus RS at the Geneva Motor Show, it promised it would deliver "well in excess of 315 horsepower." It didn't say exactly how much that would come to, but now it has. On the eve of its dynamic debut at the hands of Ken Block at the Goodwood Festival of Speed, Ford has confirmed that its new hot hatch will pack 350 metric horsepower. Those reaching for their calculators will find that works out to 345 horsepower by our standards. The power output is backed up by 324 pound-feet of torque, capable of being boosted up to 347 for up to fifteen seconds at a time. Those figures come from a retuned version of the same 2.3-liter EcoBoost turbo four as the one available in the Mustang, but produces over ten percent more power thanks to a new turbocharger, upgraded intake and exhaust, and a larger radiator. All that muscle will be channeled to all four wheels through Ford Performance's new all-wheel drive system with dynamic torque vectoring, launch control, and selectable drive modes, including a Drift Mode that (as you can see from the video below) allows the hot hatch to get more than a little sideways. Ford still isn't saying what those specs will translate to in terms of measurable performance figures, but as far as output goes, things are looking pretty good. The 30th Ford RS model already packs more power and torque than the new Honda Civic Type R (306 hp, 295 lb-ft), Volkswagen Golf R (292 hp, 280 lb-ft), Subaru WRX STI (305 hp, 290 lb-ft) or the Nurburgring-conquering Renault Megane 275 Trophy-R (271 hp, 266 lb-ft) and Seat Leon Cupra (276 hp, 258 lb-ft). It even respectably holds its own against the more upscale BMW M235i (320 hp, 330 lb-ft), Mercedes A45/CLA45 AMG (355 hp, 332 lb-ft), and Audi RS3 (362 hp, 343 lb-ft). Whether it'll outshine them all in real-world conditions remains to be seen, but we're looking forward to finding out whenever Ford deems fit to drops those performance stats on us.
