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.

New car market raining on convertibles' parade

Whether fitted with soft or hard folding lids, today's droptops are better than ever for year-round motoring. Advancements in power top mechanisms, sealing, aerodynamics, structural rigidity, rollover safety and creature comforts like heated and cooled seats mean that modern convertibles are more versatile and better to drive than ever before. Yet the segment's sales took a dive during the recession and haven't come back, Automotive News reports.
Part of that is because automakers are looking at today's more sensible buyers and simply not developing as many new models, and that lack of fresh iron is curbing sales. AN cites R.L. Polk data which notes that only about one percent of new vehicles registered in the US last year had tops that folded. Back in 2009, it was 1.4 percent, and it was 2 percent in 2006. All-in, some 151,636 convertibles were registered in 2012. That's more units more than were registered in each of the past three years, but the market has also grown as the economy has picked up speed, and as a percentage of new vehicles purchased, convertible sales are lagging.
Thus far in 2013, the Ford Mustang is America's top-selling convertible, with 6,421 units registered through the end of April, followed by its rival, the Chevrolet Camaro, at 4,751 units. The Volkswagen Beetle isn't far behind, with 4,305, but from that point, it's a steep drop off to the fourth-place Mercedes-Benz SL-Class and its 2,380 sales.

Experts wonder if aluminum F-150 gives Ford a real advantage

There's no doubt that Ford is taking a risk in producing the body of its upcoming new F-150 pickup truck in aluminum. What is up for debate, however, is whether aluminum was a wise risk to take in the first place. Wards Auto took the opportunity to poll some experts on the subject of aluminum versus steel in the automotive sector, with somewhat unsurprising results.
Richard Schultz, a project consultant at Ducker Worldwide, which bills itself as "a leading aluminum industry consultant (though they also deal in steels), suggests that the potential drawbacks to aluminum - higher costs, lower supply - aren't really impediments to the auto industry's increased acceptance of the lightweight metal.
Similarly, Randall Scheps, global automotive marketing director for Alcoa, a massive aluminum producer, counters claims that aluminum is less safe for vehicle occupants, suggesting that the use of aluminum can actually increase safety as it could potentially allow for larger vehicles with more crush space than steel.
