US automaker General Motors (GM) has increased its planned investment in Brazil by 3.5bn reais ($674.88m), taking the total to 10.5bn reais through 2028.

The revised commitment marks a 50% rise from the 7bn reais programme the carmaker had announced in 2024.

GM said the extra funding will be concentrated mainly on its operations in São Paulo state.

The spending will support updates to the Chevrolet line-up and the introduction of new technologies including hybrid powertrains in vehicles made and sold in Brazil.

The funds will also be used for improving existing plants and expansion of the group’s local engineering and production capacity.

GM added the investment will continue to prioritise new products, advanced vehicle technologies, and the development of its manufacturing and engineering base in the country.

GM South America president Thomas Owsianski said: “This investment expands our capacity to develop and produce competitive vehicles in Brazil, accelerates the adoption of new technologies, and contributes to the creation of skills and jobs that will be essential for the future of mobility.”

“Brazil has a solid industrial base, engineering capacity, a significant consumer market, and highly qualified professionals.”

Beyond Brazil, GM is also reshaping its manufacturing footprint in Mexico.

The company announced last month that it would begin locally assembling the Chevrolet Groove and Aveo at its Ramos Arizpe plant in Coahuila state from 2027, moving both models away from Asian - specifically China joint-venture - production.

The decision is part of a $1bn investment first disclosed in January 2026 and is aimed at raising domestic vehicle output at the facility to 80,000 units annually by 2030, a target that currently relies entirely on imports.
