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 gets dirty testing the 2017 Raptor

Want to hear the sweet sound of turbochargers spinning merrily away underhood of a 2017 Ford Raptor pickup truck test mule? Of course you do. And we're happy to oblige. Fortunately for you, those aren't the only sounds you'll hear when you watch the video above. We noted plenty of birds and insects, too, which means Ford has finally seen fit to share some good old fashioned muddy off-road footage of its upcoming off-road superstar as it is subjected to rigorous testing ahead of its on-sale date in the fall of 2016. It's no secret that we're big fans of the first generation of the Ford Raptor. If there was one complaint we've voiced about the truck, it's that the off-road-specific pickup could use a touch more power. Fortunately, more power is coming for 2017 as Ford replaces the outgoing 6.2-liter V8 with a new version of its 3.5-liter twin-turbo EcoBoost V6. We don't know exactly how many horses the new truck will corral, but we know it will be more than the 411 horsepower and 434 pound-feet of torque offered by the previous truck. This is the second time Ford has let out some interesting information about its tests of the next Raptor, the first focusing specifically on grueling desert trials. Considering the promises Ford is making about the 2017 Raptor's various off-road capabilities, we're keen to put the pickup through its paces ourselves. For now, though, join us in watching the video above. Related Gallery 2017 Ford SVT Raptor Desert Testing News Source: Ford Ford Truck Off-Road Vehicles Videos ford f-150 svt raptor ford raptor

Fiat boss Elkann being mentored by... Bill Ford?

Fiat Chairman John Elkann has been turning to an unusual source for advice on the car business. While speaking during an interview with The Detroit News, Elkann said he often asks Bill Ford Jr. for advice on how to proceed with the turnaround at Chrysler. "It's great to have the opportunity to share this with someone like Bill, who has experienced many things and gone through many things ... especially linked to Detroit." Elkann said.
As the Agnelli family heir, Elkann has inherited a long and fruitful friendship with the Ford family. While Giovanni Agnelli built his first Fiat four years before Henry Ford created his first vehicle, it was Ford that showed Agnelli the benefits of mass production and helped pave the way for what would become the Fiat empire.
Giovanni's grandson, Gianni, helped mentor Bill Ford when he was elected chairman of Ford Motor Company. Now, Ford is returning the favor by helping Elkann navigate the automotive industry's tumultuous waters.
