Oh they did innovate alright. The Ecoboost engine was an innovation. A surprising amount of power from a small lightweight engine. The Powershift transmission was an innovative transmission and was quite efficient.

Unfortunately those innovations sucked ass. The Ecoboost engines kept destroying themselves because the timing belts soaked in hot engine oil kept disintegrating. The Powershift transmission was such a terribly broken piece of machinery that even the engineers who designed it told corporate that it was crap and should not be used.
