General Motors and Hyundai Motor on Wednesday outlined plans to develop five vehicles together as they seek to lower costs amid growing competition from nimble Chinese rivals, although some analysts questioned whether the plan would work.

Tar makers will make four automobiles for the South and Central American markets, including a compact SUV, a car and a pickup and mid-size pickup truck.

The carmakers sealed a partnership in 2024 to jointly develop vehicles, engines and clean technologies such as electric and hydrogen powertrains.
