2024 Cummins ISX15 Smartadvantage™ Powertrain - HD Truck Cummins ISX15 450 SA Direct Drive

The new SmartAdvantage™ Powertrain takes the power of Cummins ISX15 with SmartTorque2 (ST2) and combines it with the smooth shifting of the Eaton Fuller Advantage 10-Speed Automated Transmission for improved fuel economy. The engine and transmission share critical data, determining the torque required to deliver the power level drivers need. Error-free, guessproof shifting makes every driver in your fleet as efficient as your best driver.

Cummins ISX15 with SmartTorque2 (ST2) is available exclusively with the SmartAdvantage™ Powertrain. Higher torque is delivered earlier in the rpm range so you can cruise at 1150 – 1240 rpm and still get the torque and power needed to match real-time load demand. Fuel economy is improved through the combination of downspeeding, optimized communications between the engine and transmission, and the effective use of direct drive. These advanced technologies make it easier for drivers to operate within a larger “sweet spot” for better fuel economy.

Features may include:

The patented design is widely recognized as the industry leader for performance. Electric actuation improves precision and responsiveness. The VGT Turbocharger also increases fuel economy and braking horsepower.

Delivers superior performance regardless of engine rpm. Multiple injection events per cycle improve fuel efficiency and enable smoother, quieter operation.

Proprietary system consists of a Diesel Particulate Filter (DPF) and Selective Catalytic Reduction (SCR) technology for near-zero emissions.

Fleetguard filters protect against corrosion and contaminants that can cause performance issues. High quality DEF is widely available at authorized Cummins and Fleetguard locations, as well as in bulk delivery.

A single ECM manages the engine and aftertreatment system for optimum performance and fuel efficiency.
