The GM Small Gasoline Engine (SGE) is a family of small-displacement three- and four-cylinder gasoline engines ranging from 1.0 L to 1.5 L, developed by Adam Opel AG, Shanghai Automotive Industry Corporation (SAIC), MG Motor (MG), Shanghai GM (SGM) and the Pan-Asia Technical Automotive Center (PATAC).
The new global family is designed to improve fuel economy, performance, and emissions, reduce noise and vibrations. To achieve this, it features lightweight design and advanced technologies like gasoline direct injection, turbocharging, variable length intake manifold and alternative fuel compatibility. It utilizes modular approach with interchangeable components that can be suited to specific application.
The initial engine variants include
To aid with NVH (Noise, vibration, and harshness) levels the direct injection fuel rail mounts to the cylinder head and valve cover via bushings that isolate that loud ticking noise the injector pintles make. GM claims that the 1.0-liter turbo is 25 percent (3 dBA) quieter than the Ford Fiesta's 1.0-liter turbo, and the 1.4-liter is up to 50 percent (6 dBA) quieter than the VW/Audi 1.4-liter turbo. Other silencing measures include a bed-plate cylinder block that increases stiffness, a stiffened aluminum front cam cover. Three-cylinder variants get a counter-rotating (engine-speed) balance shaft that is integrated with the oil pump and located inside the two-piece aluminum oil pan to prevent radiated noise. GM claims the EcoTec triple will idle more smoothly than Ford's three-cylinder, which does not use a shaft.
All turbocharged variants will provide 90 percent of their max torque between 1500 and 5000 rpm, with peak power arriving between 5600 and 6000 rpm. The MHI turbos are sized to provide quick torque response, and are mounted very close to the cylinders, thanks to cylinder heads that incorporate the exhaust manifolds in the head.
To reduce mass, the engines are compact in all directions, made almost entirely of aluminum, and feature composite intake manifolds. This removes 44 pounds (20 kg) from the existing 1.4-liter turbo in the Cruze and makes it 8 pounds (4 kg) lighter than the 1.4-liter VW turbo. GM says this engine weighs 216 pounds (98 kg), ready for installation.
The engines will debut in the 2014 Opel Adamand will be produced in Szentgotthárd, Hungary and GM's Flint Engine plant. The new engine family will spread to other brands and markets by the end of the decade and will replace three separate engine families (S-TEC, Family 0, and Family 1).

The GM Ecotec engine, also known by its codename L850, is a family of all-aluminium inline-four engines, displacing between 1.4 and 2.5 litres. While these engines were based on the GM Family II engine, the architecture was substantially re-engineered for the new Ecotec application produced since 2000. This engine family replaced the GM Family II engine, the GM 122 engine, the Saab H engine, and the Quad 4 engine. It is manufactured in multiple locations, to include Spring Hill Manufacturing, in Spring Hill, Tennessee while the engine block and cylinder heads are cast at Saginaw Metal Casting Operations in Saginaw, Michigan.
The LS based small-block engine is the primary V-8 used in General Motors' line of rear-wheel-drive cars and trucks. Introduced in January 1995, it is a "clean sheet" design with only rod bearings, lifters, and bore spacing in common with the longstanding Chevrolet small-block V-8 that preceded it as the basis for GM small-block V-8s. The basic LS variations use cast iron blocks, while performance editions are all aluminum with cast iron cylinder liners. The engine block and cylinder heads are cast at Saginaw Metal Casting Operations in Saginaw, Michigan.
The General Motors 60° V6 engine family was a series of 60° V6 engines which were 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 GM High Feature engine is a family of modern General Motors DOHC V6 engines. The series was introduced in 2004 with the Cadillac CTS and the Holden Commodore (VZ).
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 Quad 4s is a family of principally DOHC inline four-cylinder engines produced by General Motors' Oldsmobile division between 1987 and 2002; a single SOHC version was built between 1992 and 1994.
General Motors' Opel subsidiary in Europe designed a compact V6 engine with an unusual 54° vee angle. It was an iron block/aluminum head DOHC design with 4 valves per cylinder. All 54° engines were assembled at Ellesmere Port in England.
The Mitsubishi Sirius or 4G6/4D6 engine is the name of one of Mitsubishi Motors' four series of inline-four automobile engines, along with Astron, Orion, and Saturn.
The Mitsubishi 4G9 engine is a series of straight-4 automobile engines produced by Mitsubishi Motors. All are 16-valve, and use both single- and double- overhead camshaft heads. Some feature MIVEC variable valve timing, and it was the first modern gasoline direct injection engine upon its introduction in August 1996.
The Family 1 is a straight-four piston engine that was developed by Opel, a former subsidiary of General Motors and now a subsidiary of PSA Group, to replace the Opel cam-in-head engines for use on mid-range cars from Opel/Vauxhall. Originally produced at the Aspern engine plant, production was moved to the Szentgotthard engine plant in Hungary with the introduction of the DOHC version. GM do Brasil at São José dos Campos, GMDAT at Bupyeong and GM North America at Toluca also build these engines.
The Family 0 is a family of inline piston engines that was developed by Opel, at the time a subsidiary of General Motors, as a low-displacement engine for use on entry-level subcompact cars from Opel/Vauxhall.
The PSA XU is a family of internal combustion engines used in Citroën and Peugeot automobiles. It became the dominant mid-size engine in Peugeot and Citroën products through the 1980s and 1990s.
General Motors introduced a line of Diesel V8 engines for their C/K pickup trucks in 1982. This engine family was produced by GM through 2000, when it was replaced by the new Duramax line. AM General's subsidiary General Engine Products (GEP) still produces a military variant of this engine for the HMMWV.
The Family II is a straight-4 piston engine that was originally developed by Opel in the 1970s, debuting in 1979. Available in a wide range of cubic capacities ranging from 1598 to 2405cc, it simultaneously replaced the Opel OHV, Opel CIH and Vauxhall Slant-4 engines, and was GM Europe's core powerplant design for much of the 1980s.
The Tau is a family of gasoline V8 engines produced by the Hyundai Motor Company. It replaced the Omega engine line.
Medium Gasoline Engine (MGE) is a medium-displacement 4-cylinder gasoline engine developed by Opel Automobile GmbH and marketed as 'SIDI Ecotec'.
The Opel cam-in-head engine (CIH) is a family of automobile engines built by former General Motors subsidiary Opel from 1965 until 1998. Both four- and six-cylinder inline configurations were produced. The name derives from the location of the camshaft, which was neither cam-in-block nor a true overhead camshaft. In the CIH engine the camshaft is located in the cylinder head but sits alongside the valves rather than above them. The overhead valves are actuated through very short tappets and rocker arms. The four-cylinder CIH was largely supplanted by the Family II unit as Opel/Vauxhall's core mid-size engine in the 1980s. A four-cylinder version of the CIH remained in limited production until 1998, and six-cylinder versions of the CIH until 1995.
The Medium Diesel Engine (MDE) is a four-cylinder diesel engine developed by Adam Opel AG and branded "1.6 CDTI Ecotec" in most markets. Opel also adds the marketing term "Whisper Diesel" in some markets, claiming relatively low levels of noise, vibration, and harshness. Production commenced in late 2013 at Szentgotthárd, Hungary. The MDE is Opel's first all-aluminum diesel engine and offers a power density of 85 hp (63 kW) per liter 136 PS in its most powerful version. Maximum power and torque have been increased versus the previous-generation 1.7-liter engine, while fuel consumption has been reduced by up to 10 percent compared with a 2.0-liter CDTI engine of similar power output. This new 1.6 CDTI engine will replace the current 1.7-liter and lower-powered 2.0-liter diesel engines in a wide range of Opel models, with more- and less-powerful versions to come. The most powerful version of this engine, delivering 136 PS at 3,500–4,000 rpm and 320 N⋅m (236 lb⋅ft) at 2,000 rpm, was first introduced in the 2013 Opel Zafira Tourer, and later in the 2014 Opel Astra J and restyled 2014 Opel Meriva B. In 2014, versions were released with power outputs of 110 and 95 PS.
