2015 Ford Mustang EcoBoost loses big power on 87 octane

The 2015 Ford Mustang with the 2.3-liter EcoBoost four-cylinder is a pretty potent package on paper. With 310 horsepower and 320 pound-feet of torque, it boasts better performance numbers than the 3.7-liter V6, but with better fuel economy as an added benefit. However, if you're in the market for one of these boosted 'Stangs, you should probably keep in mind that it really prefers to gulp premium, 93-octane fuel. It can drink 87-octane swill in a pinch, but you're going to find significantly less power underfoot when pulling away. While it's not shocking that the ponies are dialed back with a lower grade of gasoline, an alleged page from a Ford training manual obtained by Mustang 6G purports to show just how much power is lost, though. According to this document, the 2.3-liter EcoBoost makes 275 horsepower and 300 pound-feet of torque when running on lower octane fuel. That's a substantial reduction of about 11.3 percent compared to when the engine drinks 93 octane. Interestingly, according to Mustang 6G, that finding was a bit better than expected, because a Ford engineer reportedly said power would be down about 13 percent without altering peak torque. In speaking with Autoblog, Paul Seredynski of Ford powertrain communications, objected to part of this document. While he couldn't confirm the specific losses listed for the Mustang EcoBoost, "torque remains unchanged" with lower octane gasoline, Seredynski said. He speculated this training manual page was "possibly from before the engine was certified" and therefore showed incorrect figures. Serendynski did confirm that the automaker recommends using 93 octane, and like all modern engines, the software adapts if it's lower. "Peak power would be reduced" by using a lesser grade, he confirmed.

Next SVT Mustang may axe Shelby name, go naturally aspirated

Following our first glimpse at the 2015 Ford Mustang out on the road, the fine folks at Road and Track have divulged some details on what the Blue Oval's next pony might have in store. We've already seen that the car will get some very sleek, Evos-inspired design cues, and an independent rear suspension is indeed in store. These new details, however, concern the muscle car's beating heart.
For starters, the base Ford coupe is expected to carry on with V6 power, likely from the same 3.7-liter unit found in today's car. From there, R&T says the next step up will be a four-cylinder EcoBoost engine, likely displacing 2.3 liters, putting out as much as 350 horsepower. Of course, a Mustang wouldn't be a Mustang without V8 thrust, and R&T states that the 5.0-liter Coyote V8 will continue on into the 2015 car, making something like 450 horsepower.
But it's at the high end of the Mustang range where things will, reportedly, get very, very interesting. Road & Track claims that the top-shelf 'Stang will likely lose the supercharger from its engine, producing a metric crap-ton of naturally aspirated grunt instead. Additionally, the SVT-fettled Mustang will likely be dropping its Shelby moniker, in favor of "a name you're familiar with," according to the magazine (you know, like, Cobra).

Here are the best-selling cars and trucks from January 2015

Every month, Autoblog slogs through all the sales figures reported by automakers that do business in the United States, and, after a little bit of sorting, we put it into an easy-to-read chart in an attempt to make it as easy as possible to follow the ins and outs of sales and shipments. But that only covers the brands themselves, not the individual models they sell. And we think you'd all be interested in knowing which vehicles beat their rivals in sales from month to month, so we've put together this handy gallery to keep you in the know. While the leader of the pack may not come as much of a surprise, the order that the top ten finishes in changes frequently – due to automaker deals, the price of gas, etc. – and we've included some statistics to help you see how their current performance stacks up to month's past.
