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.

Creations n' Chrome Top Notch Mustang is a one-of-a-kind fox

Is there a cooler car from the 1980s and early 90s to mod than a Fox-body Ford Mustang? No, there isn't. If you disagree with us, we suggest you have a look at this 1990 Mustang Coupe, which just might change your mind. Although considering just how extensively modified this car - the Top Notch Mustang from Creations n' Chrome - is, we wonder just how much Ford is left in this old pony.
It rides on a custom race tube chassis that weighs a scant 700 pounds, while carbon-fiber bits and bobs help lower the overall curb weight to a mere 2,400 pounds. When paired with supercharged, 5.0-liter, Aluminator V8 from Ford Racing, the results are, doubtlessly, exciting. 855 horsepower at the rear wheels and 667 pound-feet of torque are available from that force-fed V8 should be just plenty for this car's intended purpose of running in standing-mile competitions.
The Top Notch Mustang is more extreme than just weight savings and a big engine, though. That 5.0-liter is essentially in what's known as a front-mid layout - where the engine is actually behind the front axle. In this case, the 5.0-liter V8 is 17 inches further back than a factory Fox-body, for better weight distribution. As a result, the cabin has been completely overhauled. An SLA front suspension, wheels from HRE, Wilwood brakes and Sparco interior items round out the extensive list of mods.

2014 Roush Stage 3 Mustang

Up until now, it's been some years since I managed to get behind the wheel of the hot Mustangs tuned by the folks at Roush Performance. My memories of those vehicles are fond, as the Roush up-fits usually make for better-driving examples of the iconic Ford pony, with better-tuned suspensions, excellent short-shift kits and, of course, huge additions of power. The wake-your-neighbors aural characteristics of these cars have been nothing short of outstanding, too.
But in the years since my last experience with the Roush formula, Ford's own development team has churned out some pretty potent 'Stangs. We currently live in a world where the Blue Oval will sell you a Mustang with 662 horsepower from the factory, and the recently departed Boss 302 remains one of the best Mustangs - and best sports coupes - the Autoblog crew has ever driven.
So with great-driving and hugely powerful Mustangs coming straight off the line at Ford's Flat Rock Assembly Plant, does the Roush package still offer that extra special something to make it stand out? I spent a week with a Stage 3 coupe to find out.
