The new Cummins X15 engine is now available with Freightliner Argosy models.

It is available in output ratings ranging from 485hp to 600hp and up to 2050lb-ft.

An upgrade of the 15-litre ISXe5, the new X15 features Advanced Dynamic Efficient Powertrain Technology (ADEPT) – a suite of advanced electronic features capable of delivering fuel economy through improved powertrain integration.

Tested in Australia since last year, ADEPT is for use with Eaton’s 18-speed automated UltraShift Plus transmission.

It uses load, speed and grade-sensing technology to initiate adjustments to engine power, torque and transmission gear selection to take advantage of vehicle momentum for better fuel economy.

The ADEPT package includes two features:

  • SmartCoast – operates when the vehicle is on a moderate downhill grade by disengaging the front box of the transmission and returning the engine to idle to reduce drag, maintain momentum, and ultimately improve fuel economy. Once the engine commands the transmission to be put back in gear, the appropriate gear is engaged.
  • SmartTorque – uses torque management intelligence to help eliminate unnecessary downshifts and keep the engine operating in the most fuel efficient ‘sweet spot’. Torque is varied across all gears depending on torque requirement.

The release is timed with the availability of Cummins Connected Diagnostics – a telematics system that automatically processes fault code data, sending instant notifications from Cummins detailing probable root cause and providing recommended actions.

There are plans to add Over-the-Air (OTA) engine programming and customisation to the engine in the near future to allow reprogramming or recalibration of the engine without having to take the truck to a service station.

The new X15 engine is also available with the Detroit DD15.

Freightliner says it is the only truck manufacturer to offer customers a choice of 15-litre engines for a heavy hauling B-double truck.
