List of GM engines

This is a list of engines either produced by General Motors or used in its products.

Divisions

Until the mid-1970s, most General Motors brands designed and manufactured their own engines with few interchangeable parts between brands.[1] In the mid-1960s, there were 8 separate families of GM V8 engines on sale in the USA.[2]

By the 1970s, GM began to see problems with this approach. For instance, four different North American divisions (Chevrolet, Pontiac, Oldsmobile and Buick) offered four completely different versions of a 350 cu in V8 engine - very few parts would interchange between the four designs despite their visual similarities, resulting in confusion for owners who (quite naturally) assumed that replacement parts would be usable across the board. In addition to these issues and the obvious overlap in production costs, the cost of certifying so many different engines for tightening worldwide emissions regulations threatened to become very costly.

Thus, by the early 1980s, GM had consolidated its powertrain engineering efforts into a few distinct lines. Generally, North American and European (Opel) engineering units remained separate, with Australia's Holden and other global divisions borrowing designs from one or the other as needed. GM also worked out sharing agreements with other manufacturers like Isuzu and Nissan to fill certain gaps in engineering. Similarly, the company also purchased other automotive firms (like Saab and Daewoo), eventually folding their engine designs into the corporate portfolio as well.

GM´s German subsidiary, Adam Opel AG, relies on a range of 3, 4 and 6 cylinder petrol and diesel engines. A survey of their range shows a reliance on petrol and diesel 4´s, though as of 2014 there is only one 3-cylinder engine and one 6 cylinder engine in service in Opel´s passenger car range.

In addition to automobile and truck engines, GM produced industrial engines, which were sold by brands such as Detroit Diesel, Allison, and Electro-Motive. Most of these engine designs were unrelated to GM's automotive engines.

From the 1950s through the 1970s, each GM division had its own V8 engine family. Today, there are only two families of V8 engines in production for road vehicles: the Generation IV small-block and its Generation V small-block derivative.

Truck engines

In 1937 GM founded the GM diesel division Detroit Diesel which operated for 63 years. In the 1980s and 1990s GM produced the 6.2 L and 6.5-liter V8 Diesels for use in light trucks and in the HMMWV.

Today, GM uses Diesel engines from DMAX, originally a joint corporation between GM and Isuzu, namely the Duramax V8 engine and Isuzu 6H Engine (for trucks).

Industrial engines

Detroit Diesel Series 92 engines

GM diesels stem from the acquisition of Winton Engine Corporation in 1930. Winton was based in Cleveland, and initial production continued in that city. These were mid-sized engines. The main customer of Winton was the Electro Motive Corporation, the pioneering producer of diesel-electric locomotives. GM acquired Electro Motive at roughly the same time as Winton. These two companies were merged to become the Electro Motive Division (EMD) of GM in 1941, which was responsible for locomotive production and engine design. A further division, the Cleveland Diesel Engine Division, was responsible for submarine, marine and stationary versions of the EMD engines. Finally, in 1937 GM set up a third diesel division in Detroit, the Detroit Diesel Engine Division. The Electro Motive Division was responsible for mid- and large-displacement engines (over 150 cubic inches per cylinder) while the Detroit Diesel Division was responsible for small-displacement engines (50 through 149 cubic inches displacement). The Canadian market was served by a single company, General Motors Diesel, which produced versions of the EMD and Detroit engines.
