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.
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.
