Big Results for Every Job

With a Cummins ISB6.7 engine at the core of your medium-duty business, you get the most flexible engine option, delivering a low cost of operation with maximum uptime. It’s available at 200–325 HP and 520–750 lb/ft. With the HPCR fuel system, flexible injection timing allows multiple injections per cycle, maximizing fuel economy and performance while decreasing noise and emissions.

Built for Your Bottom Line


Designed for your less-than-truckload, regional distribution and vocational applications, the Detroit DD13 engine with BlueTec SCR emissions technology gives you the flexibility of multiple options for horsepower and torque, all in a package that provides great fuel economy, easy serviceability, consistent horsepower and robust performance.


Designed to Work Harder. Every Day

The Cummins ISC8.3 Engine—trusted by drivers and owners alike—offers one of the highest power-to-weight ratios in its class, with such heavy-duty features as replaceable wet liners, an XPI fuel system and a Cummins Aftertreatment system. It’s designed to work harder for you every day, on every route, at every RPM.

Power the Evolution

Freightliner engineers re-examined, then re-designed many features of the DD15 to reach a high level of performance. The DD15 runs a proprietary asymmetric turbocharger to reduce weight and complexity, and as a result is more compatible with EGR technology.


A Better Value Package, Every Mile

With one of the highest power-to-weight ratios in its class—and heavy-duty features like replaceable wet liners, XPI fuel system and an improved ECM along with enhanced airflow—the Cummins ISL9 Engine gives you the high-level performance and reliability you need to handle every load for every hour you’re on the road.
