2015 Ford Mustang to swap out base V6 for 330hp four-cylinder?

Ford's next-generation Mustang could arrive with the heart of a Focus RS.

Ford's next-generation Mustang will reportedly share its entry-level engine with the next Focus RS hot hatch. Ford's all-new Mustang is expected to bow for the 2015 model year.

Speaking with the UK's Auto Express, Matthias Ton, head of Ford's global performance car division, revealed that Dearborn-based automaker is developing a new 2.3L EcoBoost four-cylinder that will be used in the base model Mustang as well as the next-generation Focus RS. The four-cylinder is expected to replace the Mustang's current 3.7L V6.

Thanks to Ford's EcoBoost turbocharging technology, the four-cylinder will reportedly develop upwards of 330 horsepower. That would represent a 25 horsepower gain over the Mustang's current V6, and the turbo four would undoubtedly trump the six-pot's 280 lb-ft of torque.

And given Ford's dedication to efficiency, the four-cylinder Mustang would certainly best the 3.7's ratings of 19/31mpg city/highway.

The 2.3L could be ready to launch with the new Mustang for the 2015 model year, but the Dearborn-based automaker has been known to delay engine upgrades by a model year or two.
