Laugh at the Fuel Pump
Lower Your Fuel Costs
More Power, Less Fuel
You read that right: No more choosing between weak pulling power or painful moments at the fuel pump. The game-changing DD15 gives you both: amazing driveability and up to 5% better fuel economy than the notorious fuel-miser, the Series 60.
Shift Less, Burn Less
Because the DD15 has a flatter torque curve throughout its RPM range, you’ll need to shift less to maintain speed up and down small hills, or in gusty conditions. And less shifting means better fuel economy. As one of our test drivers said, “It just ate up those hills.”
Use Only the Fuel You Need
The DD15 boosts fuel efficiency by injecting only the precise amount of fuel needed for a particular speed, acceleration, altitude, and grade. Several times per second, the MCM (Motor Control Module) measures how far down you’ve got the hammer, and provides the perfect amount of fuel.
Amplified Common Rail System
The Amplified Common Rail Fuel System (ACRS) improves performance throughout the torque range and allows fine-tuning of combustion to reduce emissions, noise, vibration and fuel consumption. DD15 has one of the highest compression ratios in the industry, and when combined with the ACRS, you get an engine with impressive overall performance. The “amplified” in ACRS means that peak pressure is reached only at each point of injection,
maximizing the combustion potential of each high capacity cylinder. This electronically-optimized fuel delivery actually changes the pressure, the timing and the spray for every injection, to every cylinder, every second the engine is performing. This creates incredibly effective combustion for each and every revolution. Not only does this maximize your performance within the cylinders, but reduces deposits like soot and carbon, resulting in fewer Aftertreatment Device (ATD) regenerations. The bottom line is that all your performance demands are always being met: power, fuel efficiency and emissions.

Integrated, Reliable EGR
We built the Exhaust Gas Recirculation (EGR) system right into the core engine design, making the system more reliable and easier to maintain. Part of that design meant simplifying the EGR to just one valve, which makes the system more efficient at meeting clean exhaust standards and saving fuel in the process.
Runs Hotter, Runs Smarter
With two cooling sensors rather than just one, the DD15 kicks on the fans only when it needs to. And that’s not too often, because the cast-iron DD15 dissipates heat easier and can run hotter.
