When did Chevy stop using carbs?
Chevrolet stopped using carburetors on most of its new vehicles in the United States by the late 1980s, with electronic fuel injection (EFI) becoming standard across the lineup by about 1989–1990. In the years that followed, carbs largely disappeared from Chevy’s mainstream passenger cars.
The change was part of a broader industry transition that aimed to meet stricter emissions regulations and improve fuel efficiency. Carburetors, which rely on mechanical airflow and fuel metering, were gradually replaced by electronic-controlled fuel delivery systems that could optimize performance and emissions no matter the driving conditions. For Chevrolet, this shift occurred across most models through the 1980s, with a complete pivot by the early 1990s in the United States. Exceptions existed in non-U.S. markets and certain special-use vehicles, but they were rare within Chevy’s core lineup.
Timeline of Chevrolet's move from carbs to EFI
The milestones below outline the general timeline for Chevrolet’s transition from carburetors to electronic fuel injection, focusing on the U.S. market.
- Mid-1980s: Electronic fuel injection begins to appear on several Chevrolet models, including notable performance lines like the Corvette, signaling the start of the broad switch away from carbs.
- 1987–1989: EFI becomes standard on most Chevrolet passenger cars in the United States, replacing the traditional carbureted setups across many models.
- 1990: The vast majority of new Chevrolet cars and light trucks in the U.S. use electronic fuel injection, effectively ending the carburetor era for mainstream Chevrolets.
- Exceptions: Some non-U.S. markets and certain fleet or specialty vehicles may have carbureted engines into the early- to mid-1990s, but they were not common in Chevrolet’s U.S. lineup.
In summary, the Chevrolet carburetor era ended for the U.S. market by the end of the 1980s, with EFI becoming the norm by 1990. The transition mirrored a broader shift in the auto industry toward cleaner, more efficient fuel delivery systems.
Summary
Chevrolet’s move away from carburetors was completed in the United States by around 1990, driven by widespread adoption of electronic fuel injection across almost all models in the late 1980s. While there were a few exceptions in non-U.S. markets and specialized vehicles, the mainstream Chevy lineup had effectively eliminated carburetors by the turn of the decade.

- 1991 Ford LTD Crown Victoria: This was the last passenger sedan in the U.S. to be sold with a carburetor. A carbureted version of its optional 5.8-liter V8 engine was available for fleet sales, such as police interceptors, through the 1991 model year.
