The last time a four-cylinder turbo-charged engine was used in a Mustang, Ronald Reagan was president, but this may change. Ford is looking at producing a version of the EcoBoost turbocharged 4-cylinder found in the upcoming 2013 Ford Taurus for the new Mustang. The mustang would be a 2.3-liter version with a different cylinder head configuration.
Ford is also working on a 2.7-liter turbocharged V6 that is capable of powering front-wheel and rear-wheel drive cars. This engine is a likely candidate for the Edge crossover SUV, possibly the Fusion sedan and possibly the Mustang. This V6 may even power the Ford Ranger replacement.
For the Mustang enthusiasts reading this may be shedding a tear, do not worry. The 5.0-liter V8 is not going anywhere soon. However the V8 may receive direct-injection technology, to improve fuel efficiency. A source revealed there may be a plan to turbocharge the V8, but nothing is set in stone as of yet.
The Mustang lineup of engines is starting to resemble the variety Audi offers.
