List of GM engines
GM Diesel Engines In the face of the 1970s 'gas crisis', GM turned to Diesel power for economic benefit, directing the Oldsmobile division to develop a V6 and two V8 engines, to be shared with all divisions.

These Diesel engines were designed to fit into the engine bays of gasoline powered automobiles, but despite popular belief, they were not "converted" gasoline engines. Oldsmobile's diesel engines, the 5.7 L LF9 and 4.3 L LF7 V8s and 4.3 L LT6/LT7/LS2 V6, were notoriously unreliable, particularly in the earliest versions, though reliability had improved by the early 1980s with the advent of the DX block, along with better fuel filtering and water separators. By the early 80's,the 5.7L diesel was a fairly reliable engine with the introduction of the rollerized camshaft/roller lifter combination and had many improved enhancements that the late 70's 5.7L diesel engines did not have.

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 Hummvee or Hummer.

Today, GM uses Diesel engines from a joint corporation between GM and Isuzu Dmax (for trucks) but offers no domestic Diesel passenger cars. General Motors' Opel division is one of the leading proponents of Diesel cars in Europe, however. In the 1970s, Opel developed the first Opel Diesel engine ever. This 2.1- litre engine made some records in a car specially built for this purpose, the Opel Rekord D (2100 cc, 60 hp). Later versions were used in the Rekord E and the Ascona B. Vehicles using these engines could be identified by a little "hill" in their hoods. Without this "hill" in the hood, the space for the engine would have been too small. Kadett D, E and Ascona B and C models also used an Opel engine (1600 cc, 54 hp). Later Isuzu engines were installed, namely for the Corsa A (1500 cc, 50 hp (37 kW) and 1500, turbo, 67 hp) as well as for the Kadett E and Vectra A (Vectra A TD: 82 hp).

Opel today uses common rail direct injection engines designed and produced by Fiat S.p.A (MultiJet) and Isuzu (Circle L). Ownership of both designs was acquired by GM in 2005, and a new GM Powertrain Europe division in Turin, Italy (home of Fiat) was founded to manage these assets. The Fiat Diesel engine has 1900 cc, but before this cooperation, Opel had already developed two of their own engines, namely 2- litre Diesels with 82 and 100 hp (70 kW); which were installed mostly in the Vectra B. GM Daewoo recently licensed two common rail designs from VM Motori.

Many of the failures and complaints GM endured have shaped the design of Diesel engines today to be quite reliable and good performing engines. Today's Diesels have excellent fuel filtration systems to minimize failures of injection systems. Many manufacturers require owners to use specific types of oils in their diesel engines, and the use of these oils must be proven for warranty claims (Volkswagen TDI). Drivers also complained of the lack of power, unpleasant noise, and the dirty, smelly exhaust from early GM diesels. Today's diesels with common-rail injection tackle all these shortcomings. They are extremely efficient, yet provide significantly more power than older diesels, and they do so with significantly less pollution and noise. Today's dealer mechanics have also undergone the proper training to service the engines properly.

GM Straight-6 Engines
GM has produced a few families of straight-6 engines. The first was introduced 1929 to replace the straight-4 previously used in Chevrolet cars. It lasted until the 1970s in GM cars, and all the way until 1988 in Chevrolet and GMC trucks/vans. A new straight-6 was introduced in 2002 as part of GM's Atlas truck engine program.

Non-GM:
1999- Daewoo XK6 used in the Daewoo Magnus/Daewoo Tosca Holden in Australia also used straight-6 engines for a number of years in their family sedan models, with local engines ranging in size from 2.15L (132ci) in the original Holden 48-215 of 1948, to the 3.3L (202ci) six used in the 1970's and 80's, up until 1985 with the VK Commodore model. These engines were colour coded and often referred to by the colour of their engine block (grey, red, blue, black). This was replaced in the 1986 VL Commodore model to coincide with unleaded fuel being required in Australia. Since the old engine was considered unsuitable, and a new engine hadn't been developed, the VL Commodore sported the 3.0L Nissan RB30 engine, the last straight six used in a Commodore.

GM Flat-6 Engines
General Motors produced just one flat-6 engine (sometimes called the "pancake 6"), the 1960s Chevrolet Corvair engine.

GM V6 Engines
General Motors was the pioneer of the V6 engine in the United States. At that same time, the company began designing a 60 V6 for their new compact cars. This line started slowly, powering only the smallest cars. One notable version was the DOHC LQ1, designed with Lotus. The smooth and compact 60 engine has become GM's platform of the future, spawning the new global High Value family.

Other V6es came and went in recent decades, including the V8-derived Olds Diesel 4.3 and Vortec 4300 and Premium V-based LX5. The European Opel/Cadillac/Saturn 54 V6 has spawned the company's other future V6, the global High Feature DOHC engine.
