Detroit Diesel's inline 6 cylinder Series 60 engine has been a success from the start of production in 1987. Available in 12.7L and 14L displacements, the Series 60 was the first heavy-duty diesel engine with fully integrated electronic controls in the world, and with the evolution of its electronic controls, it's still the leader. The Series 60 engine is the most popular heavy-duty diesel engine in the truck market for 12 years in a row. The overhead camshaft and cylinder head design not only maximizes engine power and performance, but optimizes fuel economy too. The Series 60 has also successfully crossed over into the off-highway markets. The Series 60 delivers up to a maximum 825 horsepower and is available for Truck, Bus, Construction & Industrial, Gen Sets, and Marine applications.
