The 5.7L Hemi was put through 300 hrs of full load full throttle 5300 rpm dyno testing during R&D. I believe and my experience has shown the newer gas engines to be a lot tougher than we give them credit for. The 3.5L Ecoboost is no different. I believe it went through the paces as depicted in the commercial. Read no more or less into it though. The creative mind can deceive and advertisers know this very well. Remember the Hemi ads? People confused them a lot and the writers knew they would.
