TOKYO -- Komatsu has teamed with a U.S. maker of commercial electric vehicles to produce electrified heavy machinery, looking to start mass production ahead of rivals as early as 2023, Nikkei has learned.

Proterra designs and manufactures electric buses. The company, founded in 2004, went public this month. Komatsu, Japan's top construction machinery maker, hopes to combine in-house components with Proterra's batteries and peripherals -- built specifically for heavy-duty vehicles like a bus -- to get to market faster.
