Detroit DD15 Gen 5 showcases durability of new diesel tech

When Detroit launched the latest iteration of the DD15 inline-six diesel engine for on-highway applications, the company promised a completely updated unit that was engineered to deliver the efficiency the market expects from a heavy-duty engine platform in the Class 8 truck segment. Less than a year later, the current generation of DD15 engines have backed up the company's claim by hitting the one-billion-mile mark of cumulative field service.

“Reaching more than one billion miles in less than one year of service is not only an impressive milestone, but a true testament to the performance of the DD15 Gen 5 engine,” said Admir Kreso, chief engineer, Daimler Truck Powertrain. “Our customers have the confidence to put the DD15 Gen 5 to the test - with great success.”
