Similarly, the Mustangs are expected to get heart transplants next year. It's still unclear what base engine will replace the old 4.0L V6 although a 2.0L EcoBoost four has been rumored. The 3.5L EcoBoost V6 is also expected to be an important part of the lineup. But the most die-hard Mustang fans only seem to care about V8s. A new 32-valve 5.0L is expected to replace the 4.6L and 5.4L V8s in the Mustang and the F-150. Unlike the 5.4L in the trucks, the new "Coyote" V8 uses a significantly lighter aluminum block, and based on the spy pics that have just turned up, it will also use an aluminum intake manifold in place of the plastic unit used on the current V8s. The Coyote should give the Mustang GT 400 hp to play with, putting it on par with the Camaro SS but at a lighter weight. Bring it on!
