German-American auto and commercial vehicle manufacturer DaimlerChrysler, parent of motorhome industry supplier Freightliner, has completed the acquisition of Detroit Diesel.

However, the acquisition of Detroit Diesel will not impact Freightliner’s use of Cummins engines on the diesel pusher chassis it supplies to the builders of Class A motorhomes, according to Freightliner.

Detroit Diesel engines are in horsepower (hp) ranges that are different from Cummins engines that are used by the motorhome sector of the RV industry, according to a Freightliner spokeswoman.

Detroit Diesel builds engines from 22- to 11,000-hp for on-highway, off-road (including power generation) and automotive markets worldwide.

DaimlerChrysler believes the acquisition of Detroit Diesel makes it the world’s largest manufacturer of commercial vehicles. In addition to Freightliner, its brands include Mercedes-Benz, Sterling, Setra and Thomas Built Buses.
