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.

This Ford F-150 might have a Land Rover turbodiesel V6

Our spy photographers just caught this Ford F-150 driving around Dearborn, wearing camouflage around the bed – not so unusual near Ford's headquarters. What's interesting with this particular mule is that it might be packing a Jaguar-Land Rover turbodiesel V6. As with the Super Duty, the F-150 prototype pictured here sports a Venturi exhaust tip popping out the side of the rear bumper behind the wheel, which – along with the sound reported by our shutterbug – suggests that it's burning oil up front. That could mean Ford has found another application for the 3.2-liter, five-cylinder Power Stroke diesel that it just federalized for the Transit van. However our sources suggest what the mule is actually powered by the 3.0-liter Lion V6 diesel that Jaguar Land Rover – once subsidiaries in Ford's Premier Automotive Group – is bringing over for the Td6 models of the Range Rover and Range Rover Sport. The engine produces a respectable 254 horsepower and a healthy 443 pound-feet of torque, and is tipped to be mated to the same ten-speed automatic transmission as the new Raptor. That could give the F-150 the kind of fuel economy and muscle it would need to challenge the likes of the Ram 1500 EcoDiesel and the heavier-duty Nissan Titan with the Cummins engine. With gas prices as low as they are, however, and sales of diesel-powered vehicles lagging, Ford could just be trying to keep up with the competition by offering a light-duty diesel pickup. With its lightweight aluminum body, the diesel F-150 could even surpass the Duramax diesel-powered Chevy Colorado and GMC Canyon for frugality at the pumps, according to Mark Williams of PickupTrucks.com. He told Autoblog that, "it makes perfect sense for Ford to do a diesel. It seems like everyone is pushing them to do a Ranger, but if they can get the F-150 to push 30 mpg it can challenge the Ram Ecodiesel and even the Colorado Duramax." Reached for comment, Ford spokesman Mike Levine sent us the following statement: "We do not speculate about future products. While diesel is a solution, it is not the solution. EcoBoost offers the ideal combination of performance and fuel economy that over 60 percent of F-150 customers are choosing."

Ford Australia debuts Ranger-based Everest SUV concept

Ford has been in hot water in Australia ever since it announced plans to end local production of the Falcon and Territory SUV. Besides canceling a model that is to Oz what the Mustang is to America, the end of production means more than a few folks will be out of work.
Keen to prove that it has a plan for the market, Ford has unveiled the Aussie-penned Everest Concept, a rough-and-tumble, seven-seat SUV. While not a direct replacement for the aging Territory (that role will eventually be filled by either the Edge or Flex, according to Car Advice) it's an indication from Ford's brass that the Blue Oval is still committed to Australia.
To prove that fact, Alan Mullaly, Mark Fields, Jim Farley and regional execs descended on Sydney for the debut of the new concept. Ford's Australian president and CEO, Bob Graziano, said of the Everest, "Our customers, our employees and Australia can be assured that we're connected to the nation and committed to our customers through terrific products with class-leading technologies."
