Who makes Buick engines?
General Motors makes Buick engines.
Buick engines are designed and built by GM's Global Propulsion Systems (the GM Powertrain group), with production at GM engine plants in North America and other GM facilities. In China, certain Buick engines come from joint ventures such as SAIC-GM. There is no separate, independent engine maker for Buick.
Where Buick engines come from
Buick's current lineup relies on GM engine families developed and produced by GM's powertrain network. The following are the main engine families currently used in Buick models across markets.
- 3.6L V6 (LGX) – The modern GM V6 family powering Buick SUVs such as the Enclave and Envision; produced by GM's Global Propulsion Systems at multiple North American and international plants.
- 2.0L turbocharged four-cylinder Ecotec family (LTG/LGX variations) – Used in Buick Envision and other models; built by GM's powertrain facilities as part of the Ecotec lineup.
- 1.4L turbocharged four-cylinder Ecotec family (A14NET) – Used in Buick Encore and related models; produced by GM's powertrain network.
- 3.8L V6 (3800) – Historically significant for older Buicks; production has largely ended as GM shifted toward newer Ecotec/LGX engines.
Across markets, these GM-engine families form the backbone of Buick powertrains. In China, some Buick engines are produced by GM's local joint ventures, such as SAIC-GM, to meet market-specific requirements.
China-market engines
Joint venture production
In China, Buick engines are frequently produced by SAIC-GM and other GM joint ventures. These locally produced engines are designed to suit Chinese market regulations and consumer preferences, and may differ in displacement or tuning from those used in the U.S. or other regions.
Summary
Buick engines are manufactured by General Motors through its Global Propulsion Systems/Powertrain organization, with some engines produced by GM joint ventures in China (notably SAIC-GM). Buick relies on GM’s Ecotec and LGX/LGX V6 engine families, reflecting GM’s centralized approach to powering Buick vehicles worldwide.
Do Buicks have good engines?
Buick had long been reliable but became synonymous with reliability with the 3800 engines it put in quite a few of their vehicles, its the most internally balanced engine ever put into large scale production. They even slapped on a supercharger lol. No Idea about the new ones but I would assume good quality as well.
