3-6% Better Fuel Economy. Cummins ISX15 With SmartTorque2.

The first choice of heavy-duty fleet owners and Class 8 drivers, Cummins ISX15 delivers unsurpassed fuel economy, reliability and resale value. Its technology has been proven in millions of miles of real-world hauling under the most extreme driving conditions.

The 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. Two ratings are currently available; 415 hp (309 kW) and 450 hp (336 kW). Both ratings include proprietary SmartTorque2 as well as Vehicle Acceleration Management. The ISX15 SmartAdvantage Powertrain will be available in applications up to 110,000 lb (49,895 kg) gross combination weight (GCW) later in 2014.

SmartTorque2 automatically senses vehicle weight, grade and operating gear, then selects the optimum torque for the best fuel economy and performance in every gear. Whether you are driving up a hill, merging onto the highway or passing slower traffic, the SmartAdvantage Powertrain provides the power you need, when you need it.

Cummins Vehicle Acceleration Management (VAM) is a unique electronic feature that is automatically enabled on Cummins ISX15 ST2 engines in the SmartAdvantage™ Powertrain. It assists with the acceleration rate from the launch of the vehicle, maintaining more consistent acceleration due to a more efficient transition through the gears. VAM results in a smoother acceleration experience for the driver and reduced driveline wear, while increasing fuel economy.

Key features of the ISX15 include:

  • VGT™ Turbocharger - This 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.
  • XPI Fuel System - Delivers superior performance regardless of engine rpm.
  • Cummins Aftertreatment System With SCR - This totally integrated design from Cummins Emission Solutions keeps emissions at near-zero levels.
  • Fleetguard Filters -Provide superior protection against contaminants that can cause performance issues.
  • Single High-Capacity ECM - A single ECM manages the engine and aftertreatment system for exceptional fuel efficiency and performance.
