Detroit Diesel Series 60 12.7L Engine Specifications & Applications

Overview of the Detroit Diesel Series 60 12.7L Engine

The Detroit Diesel Series 60 12.7L is one of the most successful and widely adopted inline-six heavy-duty diesel engines ever produced. Introduced in the early 1990s as an evolution of the 11.1L variant, the 12.7L version quickly became a workhorse across on-highway, marine, and industrial markets due to its optimal power-to-weight ratio, mechanical simplicity, and DDEC electronic control system.

With a displacement of 12.7 liters (775 cubic inches), this 6-cylinder, 4-stroke engine is turbocharged and aftercooled, capable of producing 350 to 500+ horsepower and up to 1,650 lb-ft of torque. Known for its durability, fuel economy, and easy rebuildability, the Series 60 12.7L is still supported by a robust aftermarket parts network—including full support from Diesel Pro Power for marine and industrial applications.
