Design
The OM639 is based on the four-cylinder OM640 engine and features a dual mass flywheel, exhaust gas recirculation, and Euro 4 emission standard compliance.[2] It is transversely mounted behind the front axle and inclined 60 degrees due to the sandwich floor design used in the Smart and Mitsubishi models,[3] so the engine slides underneath the floorpan instead of into the cabin in the event of a head-on collision to improve safety.[4]
