Ford so far has not used EcoBoost technology in any application where the engine ratings are expected to serve 100% duty cycle. Instead, medium duty trucks use different engine series, and where they overlap with 3/4 ton and 1-ton applications, the shared engines are down-rated from the pickup truck numbers, e.g. when the B-series Cummins is put in Class 6 and Class 7 cab-chassis.
For 2016 Ford is dropping the Cummins and going with the 6.7 Scorpion engine. Like in the past it's derated from pickup truck specs to 270/675.
