The Smart Way To Get A 3-6% Fuel Economy Advantage.
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.
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.
Four ratings are currently available: 400 hp 1450/1650 lb-ft, 400 hp 1550/1750 lb-ft, 420 hp 1550/1750 lb-ft, and 450 hp 1550/1750 lb-ft. All ratings include proprietary SmartTorque2 as well as Vehicle Acceleration Management.
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.
Vehicle Acceleration Management 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 smoother acceleration and reduced driveline wear, while increasing fuel economy.
Eaton Fuller Advantage 10-Speed Automated Transmission.
New features of the Eaton Fuller Advantage 10-Speed Automated Transmission include the strategic use of lightweight components and Precision Lubrication. Small-step technology enables downspeeding in overdrive and efficiency in direct drive. Optimized shifting is based on grade, vehicle weight, engine torque and throttle position.
Fuel economy is further enhanced through precision lubrication. Precision lubrication technology reduces churning losses, and eliminates the need for a cooler in most applications, for reduced weight and increased reliability.
