Available in the Freightliner Cascadia 116” BBC day cab, the Cummins X12 engine is designed for weight-sensitive applications. The X12 has the power of a 13L but weighs less than an 11L. With its simplified aftertreatment design, the X12 was developed to help customers stay on the road longer and get back on the road faster with longer maintenance intervals contributing to increased uptime.
The Cummins X12 is only available in a 116" Day Cab configuration with an Eaton Cummins Endurant Transmission. This combination is the lightest powertrain available for the Class 8 on-highway market, weighing only 2700 pounds.
The Cummins X15 offers ratings to deliver the performance and response customers expect. The X15 Efficiency series delivers up to 5% better fuel economy than the prior X15 Efficiency Series engine (GHG17). The X15 Performance Series offers exceptional transient response and a powerful engine brake.
