2015 Ford Mustang EcoBoost Returns 31MPG, V6 Worsens

Monroney stickers for the 2015 Ford Mustang V6 and four-cylinder EcoBoost models have leaked. With the new 4-cylinder EcoBoost returning more than expected, the V6 dropped from where it was this time last year. The question is — will buyers really care? According to the Mustang fan website Mustang6G.com, here is how the MPG data breaks down so far: - Mustang EcoBoost (manual): City 22 / Highway 31 - Mustang EcoBoost (auto): N/A - V6 Mustang (manual): City 17 / Highway 28 - V6 Mustang (auto): City 19 / Highway 28 PHOTOS: See More of the 2015 Ford Mustang GT For sake of comparison, the 2014 Ford Mustang V6 auto is rated at 19-mpg city and 31-mpg highway. That's about a 10 percent drop in highway fuel economy. But the reason owners won't care is the 2.3-liter EcoBoost inline four is rated at 310 horsepower and 320 lb. ft. of torque. That makes it a more powerful and more fuel-efficient Mustang than the V6 version that's rated at 300 horsepower and 280 lb. ft. of torque.

The EcoBoost uses direct injection, variable cam timing and turbocharging. It also will get a unique intake manifold and turbocharger housing. The EcoBoost is a different beast that some owners may not want under the hood. Plus it burns 91 octane compared to regular in the V6. What's still unknown are the fuel economy numbers for the 5.0-liter V8. It produces 435 horsepower and 400 lb. ft. of torque. Then again, anybody ponying up for the V8 probably won't care about fuel economy numbers except to brag how low they are. PHOTOS: See More of the 2015 Ford Mustang
