The new Cummins X15 engine is now available with the Freightliner Argosy in addition to the Detroit DD15. This X15 is available in power ratings from 485hp to 600hp, with up to 2050lb-ft of torque. The Cummins X15 features the Advanced Dynamic Efficient Powertrain Technology (ADEPT) – a suite of advanced electronic features capable of delivering fuel economy gains through improved powertrain integration.
The ADEPT package includes two features: SmartCoast and SmartTorque.
• 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.
With this new feature, Freightliner becomes the only brand in Australia to offer customers a choice of 15- litre engines for B-double applications. Loyal Freightliner Argosy customers can now benefit from the new Cummins X15 or the proven Detroit DD15.
