Cummins Inc. has announced its next-generation of integrated power that it says will benefit high-horsepower applications, the Cummins X15 Performance Series and the Endurant XD 18-speed transmission.

Building upon the powertrain integration of the Cummins X15 Efficiency Series and Endurant powertrain, the X15 Performance Series and Endurant XD powertrain is optimized for high gross combined weight on-highway and severe on and off-highway applications, with full application coverage to be announced at a later date, the company says. Available starting in 2021, the Cummins X15 and Endurant XD is currently going through field tests and validation.

The Endurant XD automated transmission features 18 forward speeds and up to six reverse speeds. A high-capacity bottom 8-bolt and rear power take-off provisions are offered as standard equipment, providing customers with flexibility for final equipment design and the ability to power necessary accessories. A transmission oil cooler provision is available when required, Cummins says.
