New X15™ SmartAdvantage™ Powertrain 1850 lb-ft Rating Extends Fuel Economy Leadership

Since its introduction, the SmartAdvantage Powertrain has earned a reputation for superior fuel economy and lower operating costs than the competition. Your customers that are running 2010 model year trucks can expect to see up to 20 percent better fuel economy with the X15 SmartAdvantage Powertrain.

The most recent news is that Cummins and Eaton are now offering an X15 SmartAdvantage Powertrain rated at 500 horsepower with 1550/1850 lb-ft torque. This new rating is capable of delivering an additional fuel economy gain of .75 percent for performance-oriented fleets.

The new rating is compatible with rear-axle ratings as low as 2.47, which enables engine cruise speeds as low as 1075 rpm. That’s better than some direct drive transmissions! Downspeeding also means less stress on engine components and can lead to longer engine life.

The higher peak torque rating (at least 100 lb-ft more than any other SmartAdvantage Powertrain rating) results in an improved ability to muscle up steep grades with fewer downshifts, and should have great appeal (and higher residual value) at trade-in.

This new rating is just the latest development in Cummins and Eaton’s efforts to make the SmartAdvantage Powertrain the right choice for more fleets. A complete list of available X15 SmartAdvantage Powertrain options can be seen in the table below and the Cummins PowerSpec tool can help you ensure that your customers spec the right option for their application.
