The company was founded as Freightliner Inc in 1942 and is now a division of Daimler Trucks North America, a subsidiary of the German Daimler AG. The company is known mainly for the heavy duty class 8 diesel trucks it produces, as well as classes 5-7 trucks.
As of 2005, Freightliner is the largest manufacturer of heavy duty trucks in North America with annual revenue of over $32 billion (2006 est.) and over 22,000 employees (including Detroit Diesel). Because Freightliner LLC is a wholly owned subsidiary of Daimler, a non-American corporation, it is not included in Fortune 500 rankings. It is comparable to the 125th largest company in those rankings based on the criteria used.
