New ISX15 SmartAdvantage™ Powertrain Ratings in Q4 2016

In response to customer needs, Cummins added ISX15 ratings earlier this year with 1850 lb-ft of torque, including a new 475-hp rating. Customers have the choice of straight ratings or SmartTorque2 technology. These engines are configured specifically to leverage downspeeding technology and deliver exceptional pulling power at lower engine rpm while simultaneously increasing fuel economy.

Now, Cummins and Eaton® are offering three new ISX15 SmartAdvantage Powertrain ratings as well. Rated at 400 hp, 450 hp and 475 hp, these engines deliver 1850 lb-ft of peak torque in gears eight through 10 of the Eaton Fuller® Advantage™ 10-speed AMT transmission. Availability will begin during the last quarter of 2016.

The integration of engine and transmission, combined with downspeeding capabilities, will result in fuel-economy gains over and above the current product, for a lower total cost of operation and ownership. Here is the complete list of ISX15 SmartAdvantage Powertrain ratings:

Customers running U.S. Environmental Protection Agency (EPA) 2010 engines should realize fuel economy gains that exceed 12 percent to 15 percent with this new SmartAdvantage Powertrain. Cummins also offers an online spec’ing tool for the SmartAdvantage Powertrain, so you can walk customers through the process of identifying the optimal spec for their operation.

In 2017, the X15 SmartAdvantage Powertrain will be offered with 1850 lb-ft peak torque at ratings of 400 hp, 450 hp and 500 hp – more horsepower than has previously been available with the SmartAdvantage Powertrain. The addition of these new ratings are part of Cummins and Eaton’s commitment to make the SmartAdvantage Powertrain the right choice for a broader range of customers with varying duty cycles.
