The Detroit Diesel Corporation started in 1938 as a part of General Motors, but it's now part of the Tognum and Daimler AG companies. Detroit Diesel is headquartered in Detroit, Michigan, and specializes in both heavy- and medium-duty diesel engines. The Detroit Diesel Series 60 engine is an energy efficient engine designed for both consumer and commercial vehicles, and it comes with a two-year unlimited mile warranty. Only purchases from an authorized dealer qualify for the warranty.


The Series 60 engine displacement is 3.7 gallons and refers to how much fluid the pistons can move from the top dead center to the bottom dead center of the cylinders. This is an inline 6-cylinder engine, and it weights 2,840 lbs. The engine bore is the diameter of the cylinders, and the bore for the Series 60 is 5.24 inches. The stroke is 6.61 inches, which is the total movement length of the piston. The compression ratio is the comparison between the largest capacity volume vs. the smallest capacity volume of the combustion chamber, and the Series 60's ratio is 17 to 1. The onboard electronics system is the DDEC VI, which controls and guards the engine.


The Series 60 engine improves fuel efficiency and meets current (as of 2010) emissions standards. The engine features a one-piece piston, which has a high compression ratio and helps minimize piston friction. This helps reduce oil consumption and soot loading, and it helps the engine perform better overall. Another feature designed to reduce emissions is the exhaust gas recirculation (EGR), which cools the engine using water and then recirculates the exhaust. This system also cleans up the exhaust before it's released back into the air, and the system reduces the overall weight of the engine by 10 pounds, according to Detroit Diesel. The cylinder head of this system also helps move air around the engine.


The horsepower of the Series 60 engine ranges from 425 to 515 hp, depending on the model, with 1,200 RPM. The engine lean range or cruise power rating of the Series 60 ranges from 425 hp to 515 hp with a maximum RPM of 1,100. You don't need to change the oil until nearly 30,000 miles, and the engine starts at temperatures down to -40 degrees Fahrenheit. This engine has undergone nearly 14 million miles of testing.
