Cummins EX Ratings

The NEXT Level

Of Powertrain Optimization

 

 

 

The combination of either the 2020 or later X15 Efficiency Series or 2021 X12 engine with EX ratings, Endurant HD transmission, and GPS look-ahead data gives you the next level of powertrain optimization. Currently, EX ratings provide access to 4 unique features including On-Ramp Boost - a proprietary feature exclusive to Cummins. Future updates will continue to provide access to electronic engine and transmission features that improve driver performance and operational efficiency.

Previous powertrain features like SmartCoast and Predictive Cruise Control - which required a unique ADEPTTM calibration - are enabled on EX ratings by default.
