Dating back to 1938, Detroit Diesel, or better known since 2011 as Detroit, has a long-standing history of developing diesel engines that last. They offer a complete line of heavy-duty diesel engines, axles, transmissions, safety systems, and connected vehicle services for the commercial transportation industry. Their engines are used in many vehicles including Thomas Built Buses and feature power and best-in-class fuel economy.
Born in the Great Depression, General Motors created the GM Diesel Division, and that same year they released their first series engines, Series 71. These engines were built because tanks, landing craft, road building equipment, and stand by generators needed compact, lightweight, two-cycle engines. The engines proved to be successful and during a time where jobs were hard to come by, they were able to employ around 4,300 employees.
Even after World War II ended and the demand for engines that could be used in vehicles like tanks started to decline, the business still continued to grow. In 1988 a joint venture between Penske Corporation and General Motors created Detroit Diesel Corporation. Just shortly after they became publicly traded on the stock market in 1993 and then was sold to DaimlerChrysler in 2000.
Under new ownership, they have had many changes and accomplishments, including a new name, celebrating 75 years and a complete refurbish and retool of their Detroit facility. More recently, in 2007 they launched their DD engine platform.
