The General Motors 60° V6 engine family is a series of 60° V6 engines produced for both longitudinal and transverse applications. All of these engines are 12-valve cam-in-block or overhead valve engines, except for the LQ1; which uses 24 valves driven by dual overhead cams. These engines vary in displacement between 2.5 and 3.4 litres and have a cast-iron block and either cast-iron or aluminum heads. Production of these engines began in 1980 and ended in 2005 in the U.S., with production continued in China until 2010. This engine family was the basis for the GM High Value engine family. These engines have also been referred to as the X engines due to their first usage in the X-body cars.
The Buick V6, popularly referred to as the 3800 in its later incarnations, originally 198 cu in (3.2 L) and initially marketed as Fireball at its introduction in 1962, was a large V6 engine used by General Motors. The block is made of cast iron and all use two-valve-per-cylinder iron heads, actuated by pushrods. The engine, originally designed and manufactured in the United States, was also produced in later versions in Australia. It was the first six-cylinder engine designed exclusively for Buick products since the Buick straight-six was discontinued in 1930.
The Oldsmobile V8, also referred to as the Rocket, is series of engines that was produced by Oldsmobile from 1949 until 1990. The Rocket, along with the 1949 Cadillac V8, were the first post-war OHV crossflow cylinder head V8 engines produced by General Motors. Like all other GM divisions, Olds continued building its own V8 engine family for decades, adopting the corporate Chevrolet 350 small-block and Cadillac Northstar engine only in the 1990s. All Oldsmobile V8s were manufactured at plants in Lansing, Michigan while the engine block and cylinder heads were cast at Saginaw Metal Casting Operations.
The Oldsmobile Diesel engine is a series of V6 and V8 diesel engines produced by General Motors from 1978 to 1985. The 350 cu in (5.7 L) V8 was introduced in 1978, followed by a 261 cu in (4.3 L) V8 only for the 1979 model year. In 1982, a 263 cu in (4.3 L) V6 became available for both front and rear-wheel drive vehicles. Sales peaked in 1981 at approximately 310,000 units, which represented 60% of the total U.S. passenger vehicle diesel market. However, this success was short-lived as the V8 diesel engine suffered severe reliability issues, and the engines were discontinued after the 1985 model year.
The 122 engine was designed by Chevrolet and was used in a wide array of General Motors vehicles. The 122 was similar to the first two generations of the General Motors 60° V6 engine; sharing cylinder bore diameters and some parts. The 122 was available in the US beginning in 1982 for the GM J platform compact cars and S-series trucks.
GMC has both shared engine designs and architectures with other General Motors divisions as well as having a history of developing and using its own unique engines and powertrains such as for instance its line of their straight-6 and V8 engines.
