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.

Shelby Baja 700 takes Ford F-150 SVT Raptor to the next level

The Ford F-150 SVT Raptor can be called many things, but "underpowered" is not one of them. Still, that's never going to deter a company like Shelby from taking the off-road monster even further. Pictured here is the Baja 700, an even more extreme take on the Blue Oval's outgoing performance off-roader. The legendary Ford tuner has fitted it with a new supercharger, throttle body, injectors, heat exchanger and Borla exhaust, boosting output to over 700 horsepower. Of course Carroll's boys didn't stop there, thoroughly reworking the suspension with 3-inch King coilovers, bypass rear shocks, Rogue Racing upper and lower control arms and more, fitted to 18-inch matte black wheels with BFGoodrich K02 off-road rubber. Naturally, it's got the requisite graphics and badging to go with it all, along with a skid plate and a reworked interior by Katzkin and a three-gauge dashboard pod. Only 50 examples will be made, each priced at $45,000 – over and above the price of the base vehicle, which sells for about the same. So you're looking at a good $90k for this monster truck, before auxiliary lighting and other options are taken into account. Related Video:

Ford reveals all-new Everest SUV at Asia-Pacific forum [w/poll]

While the Explorer may have shifted from a truck-based sport-ute to a car-based crossover, Ford still offers buyers on the other side of the Pacific a Ranger-based SUV in the form of the Everest. And at the Asia-Pacific Economic Cooperation (APEC) Summit in Beijing today, the Blue Oval revealed the all-new version you see here.
Previewed in concept form over a year ago and made specifically for the Asia-Pacific market, the new Ford Everest is designed to be more refined on the road and more capable off of it. Like the Explorer once was, the new Everest is based on a stretched version of the overseas Ford Ranger pickup. Depending on the specific market, Ford will offer the new Everest with a range of engines including a 2.0-liter EcoBoost turbo four and two Duratorq turbodiesels - a 2.2-liter four and a 3.2-liter inline-five - mated to a six-speed automatic transmission.
Earmarked to take on the likes of the Toyota Land Cruiser Prado (known in these parts as the Lexus GX) and the Jeep Grand Cherokee, the new Everest promises rock-crawlers even better off-road capabilities. It's got nearly nine inches of ground clearance, over 30 inches of wading depth, a 29-degree approach and 25-degree departure angles and a set of features including on-the-fly adjustable four-wheel drive.
