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.

2016 Ford Shelby Mustang GT350R First Ride

Ford Performance Chief Engineer Jamal Hameedi was in China when he received an interesting text. Half a world away his team was shaking down the newest Shelby Mustang at Grattan Raceway in rural Michigan. The news was encouraging. The GT350R was keeping pace with a Porsche 911 GT3, even nosing ahead of it during time trials, while the GT350 was running about even with a 911 Carrera S and a Chevy Corvette Stingray. "That was a good text to get," he recounted a week later as we chatted alongside the track at Grattan. On this scorching summer day, there were no Porsches or Stingrays to be found, but we've come to preview the track-focused GT350R. Ford drivers are at the wheel, and we're riding shotgun. After several hot laps, we're left with a predictable observation: The GT350R is wicked fast and quick as hell. Much of this is thanks to the 5.2-liter flat-plane crank V8 that pumps out 526 horsepower and 429 pound-feet of torque. It's the most powerful naturally aspirated road-legal engine in Ford's 112-year history. To help the engineering process, Ford bought a Ferrari 458 Italia and ripped apart its V8. The GT350's engine ended up being 10 pounds lighter. For the coup d'grace, Ford's mill also revs to a Ferrari-like 8,250 rpm. As formidable as all of that looks on paper, it sounds even more imposing in real life (see the related video below). The engine in our GT350R crackles, growls, and opens up to a flat-out roar as we explode onto the track, gripping the door pulls to calm our nerves. Grattan is a challenging, twisty course. The corners are tight, and the elevation changes quickly. At one point, our test driver aggressively tackles a curve and we're briefly airborne. During the first stint, we reach about 140 miles per hour. But the GT350R isn't about straight-line speed or pure power. It's designed to get around a track as rapidly as possible. That means Ford took the 'base' GT350 – which should be more than at home on the track itself – and re-tuned the suspension and aerodynamics. There's a larger front splitter and rear carbon-fiber spoiler. The 19-inch carbon-fiber wheels are stiffer and lighter than comparable aluminum rollers, and they're wrapped in Michelin Pilot Sport Cup 2 high performance rubber. Additionally, Ford ripped out the back seats, air conditioning, trunk floorboard, stereo, backup camera, and anything else that wasn't necessary.

Ford ST Octane Academy [w/video]

The ST school is about more than just handbrake turns, hot laps, and sliding into parking spaces.
I felt like such a rock star. On my second pass around the UrbanCross course (read: fancy autocross) at the Ford ST Octane Academy, I absolutely nailed the exit, sliding the bright-yellow Focus ST sideways into a box the size of a parking space, all four wheels in line.
