Duramax vs. Cummins vs. Powerstroke

The big jobs in Chatham take a lot of power, and when you want the maximum power in your truck, you gotta go diesel. The three American truck manufacturers have their own brands of OEM diesel engines that amp up the horsepower and displacement for the toughest jobs. In the battle of Duramax vs. Cummins or Duramax vs. Powerstroke, we’ve got the information you need to help you make a smarter decision.

Duramax Engine

The Duramax 6.6L engine is what you’ll find under the hood of Chevrolet and GMC trucks. This engine has an exhaust gas recirculation system that improves the airflow through the engine, increasing the total amount of power. The Duramax also comes compatible with B20 biodiesel and has an electronically controlled variable-geometry turbocharger.

Cummins Engine

If you’re looking for torque, this is the engine you want. In the battle of Duramax vs. Cummins, the Cummins 6.7L engine comes out on top in the torque department with an absolutely colossal 1000 lb-ft of torque. Additionally, towing capacity tops out over 31,000 pounds, giving you the ability to tow an absurd haul with minimal fuss. You’ll find the Cummins engine in Ram trucks.

Powerstroke Engine

When comparing the Duramax vs. the Powerstroke which features in Ford vehicles, one thing that stands out for the Powerstroke is its horsepower. The 6.7L Powerstroke engine has an impressive 475 hp, providing the most muscle out of all the American diesel engines. With that said, it’s torque that you’ll need to get up to speed on Rochester-area highways.
