F3.8 (Stage V) for 2019

The inline 4-cylinder F3.8 delivers 10 percent more power and almost 20 percent more torque across the entire RPM range. EGR-free architecture reduces complexity and improves reliability. Not only do you get more power - you use less fuel, with total fluid efficiency (includes both fuel and Diesel Exhaust Fluid) improved by up to 3 percent. Equipment used in duty cycles with frequent idling can improve fuel economy even more with Cummins Stop-Start technology.
