Engine production began in Moraine, Ohio in 2000.
HistoryEdit
DMAX originally was announced in 1997<ref>History on DMax website</ref> as a 60-40 joint venture<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> between and operated by General Motors and Isuzu. Diesel engine production started in July 2000.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> The company's Duramax V8 engine has been extremely successful for GM, raising that company's diesel pickup market share to 30% in 2002, up from approximately 5% in 1999.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
The DMAX plant was built in Moraine on a land grant site adjacent to a GM plant that made the 6.2/6.5 L Diesel V8 designed by Detroit Diesel. Production of that engine began in 1982. The DMAX Moraine plant was completed in 1999,<ref name=TRH-2023/> next to Moraine Assembly, which shut down in 2008.<ref>Template:Cite news</ref><ref>Template:Cite news</ref> The DMAX Moraine plant added 80 workers in 2005.<ref>Template:Cite news</ref>
The plant is planning to increase production from 580 engines a day, in 2017, to 700 engines a day.<ref>Template:Cite news</ref> To further expand production, in 2019, GM began construction of a new DMAX plant in Brookville, which would send machined engine components to Moraine for final assembly. Completed engines were shipped from Moraine to Flint, Michigan for assembly into vehicles.<ref>Template:Cite news</ref> The Brookville plant opened in 2021.<ref name=TRH-2023>Template:Cite news</ref> Template:As of, the daily component production at the Brookville and Moraine plants are 418 blocks and 324 heads; and 500 blocks, 1,440 heads, and 855 crankshafts, respectively. Moraine produces 882 completed engines per day.<ref name=TRH-2023/>
According to financial filings, Isuzu wound down its investment in DMAX in May 2022,<ref name=TRH-2023/> leaving the company wholly owned by GM. In June 2023, GM announced plans to shift Duramax V8 production from Moraine to an expanded Campus Boulevard plant in Brookville by 2025.<ref name=DMAX-2023>Template:Cite news</ref>
