Today's brand spotlight on Detroit Diesel will explore the company's history, evolution, and engines and why they're an excellent choice for your next truck. Whether you are in the market for a new engine or just doing your research, this will be a worthwhile read. Let's get started.
Detroit Diesel Engines
Based in Detroit, Michigan, U.S, Detroit is an industry-leading engine, axles, and transmission manufacturer that caters to Western Trucks and Freightliner. Detroit now aims to provide a complete range of trucking solutions. Daimler Truck AG, a multinational commercial truck manufacturer, was the parent company of Detroit Diesel.
Since it arrived in the market in 1938, the brand has delivered over five million engines globally. In addition to the regular trucking product line, the company offers a Virtual Technician Service known as Detroit Connect for remote fault detection and support.
Beginning of Detroit Diesel
The company was initially known as the General Motors (GM) Diesel Division when it started its journey in 1938. Due to exceptional reliability and fuel economy, GM Diesel Division quickly became successful.
One of the first engines manufactured by the company was Series 71, which became very popular among heavy-duty military and construction vehicles. Series 71 came to the market almost at the same time as World War II when there was an enormous demand for heavy engines for tanks, construction trucks, and power generation machines.
GM Diesel capitalized on the growing demand, and during 1943, they reached a yearly manufacturing capacity of 58,000 through a team of 4,300 staff. Series 53, the successor of Series 71, also posted excellent sales figures and contributed to the reputation of GM Diesel in its early days.
GM formed a joint venture with Penske Corporation in the late-1980s to form the Detroit Diesel Corporation (DDC) as a subsidiary of Daimler Truck North America. In 1993, the DDC reached a market share of 33% in the heavy-duty highway truck segment, which was a leap from its 3% market share only a few years earlier. The growth also helped the company become publicly traded on the New York Stock Exchange.
Now that you know about the early days of Detroit Diesel, let’s explore how it went for the company in recent decades.
2000 – Current for Detroit Diesel
In 2000, the DDC underwent a significant organizational change when DaimlerChrysler, the German multinational automobile giant, acquired DDC. DaimlerChrysler integrated DDC within DaimlerChrysler Powersystems, a new business wing for the German company.
DDC invested $350 million to completely modernize its production plant before introducing Series 60, the new generation of DD engines, to the market in 2007. Within less than two years, Detroit Diesel sold one million units of Series 60.
DDC brought in several new engine models within a couple of years, including DD13, DD15, and DD 16, with BlueTec, a new clean diesel emissions technology. Truck Writers of North America awarded the Technical Achievement award to DD15.
