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 profiles surprisingly affluent Focus ST buyers

It comes as no surprise when Ford says that 32-percent of Focus ST buyers are under 35, but we weren't expecting this: the average annual salary of Focus ST buyers is $127,000. Twenty-two percent of non-ST Focus buyers are under 35, while their average annual salary is $67,000.
We like the Focus ST because it has 252 horsepower, is genuinely fun to drive and offers great value for performance-minded car enthusiasts; facts that are not lost on customers, it seems. Ford says that the Focus ST has the highest percentage of conquest sales for a non-hybrid model it sells, and that the top-four trade-ins are from Honda, Chevrolet, Mazda and Toyota. Demand for the hot Focus is strongest in Los Angeles, Detroit, Houston and Orlando.
"[The Focus ST is] having this kind of halo effect for other vehicles we'd hoped for when we invested in the ST brand," says John Felice, vice president of US marketing, sales and service, because it's helping to boost sales of other Ford vehicles.

2015 Shelby GT bows in Scottsdale with 627 supercharged ponies

Between the base V6, the EcoBoost turbo four, the eight-cylinder GT, the monstrous GT350 and the new GT350R (to say nothing of transmission and convertible options), muscle-car enthusiasts have a staggering array of Mustangs to choose from. And now there's one more as Shelby American has introduced the new 2015 Shelby GT. Building off the success of the 2007 Shelby GT and the 2013 follow-up, the new 2015 model was just introduced at the Ford booth at Barrett-Jackson in Scottsdale, AZ. It's based on the latest Mustang GT (whether factory fresh or commissioned from an owner's existing pony car) but upgrades with an enviable list of enhancements from Ford Racing Performance Parts, Shelby's own upgrades and top-shelf third-party components. For starters, the engine is supercharged up to 627 horsepower (with over 700 available through further upgrades). It's got 3.73 gears, a Borla exhaust, WELD Racing wheels, Michelin tires and Wilwood six-piston front brakes. Visual enhancements include a carbon-fiber body-kit (including a two-piece rear diffuser) and billet aluminum front grilles. Designed from the get-go to be sold around the world, the 2015 Shelby GT is certified for use in all 50 states and comes with a Shelby American CSM number registered in the company's registry, but all those enhancements don't come cheap: Shelby's charging $39,995 for the new GT, and that's just for the modifications. Add that to the $32k sticker on a Mustang GT donor and you're looking at over $70k – which is not only more than Ford itself is expected to charge for its own GT350, but more than Dodge gets for a Challenger Hellcat.
