Detroit Diesel – other road engines: the collective page of heavy truck diesel engines outside the named ranges, DD8 to DD16, 200 to 500 hp, displacements from 7.7 to 15.6 litres
This page gathers the Detroit Diesel truck engines the register could not assign to a named range. Detroit Diesel, headquartered in Detroit, Michigan, belongs to Daimler Truck and supplies the engines for its own Freightliner brand as well as for Western Star. The EPA engine-family codes such as TDDXH07.7MDE, TDDXH12.8NXE or TDDXH15.6GEE encode displacement in litres and show the range assignment: 7.7 litres for the DD8, 12.8 litres for the DD13, 14.8 litres for the DD15 and 15.6 litres for the DD16.

The register lists here 14 versions with 200 to 500 hp rated output at 1,500 to 2,200 rpm, model years from 2012 to 2026, maximum torque from 560 to 1,850 Nm at 1,000 to 1,400 rpm. Injection is recorded as Direct Injection on 12 engines and as Electronic Direct Injection on 2, with fuel mostly ultra-low-sulfur diesel; all certified versions are recorded for the US market.
Detroit Diesel is the classic engine supplier for Freightliner tractor units and distribution trucks in North America, with the DD13 as the standard long-haul engine and the DD16 as the strongest version for heavy haulage.
On a used purchase, operating hours and the service history of the injection system, the condition of the turbocharger, the tightness of the charge-air ducting, and the function of the diesel particulate filter and SCR catalyst with AdBlue dosing all count; parts and service run through the Freightliner/Detroit Diesel dealer network.
