Alex Palou, the 2021 IndyCar champion, has been named as one of McLaren's reserve drivers for the 2023 Formula One season.

The 25-year-old, who ran in testing with the outfit across the 2022 season, is set to balance his time in the cockpit with his schedule in IndyCar.

Earlier this year, Palou was involved in a dispute over his future, with McLaren and then-current team Ganassi both suggesting he was under contract for next year with them.

After the latter initially filed a lawsuit against the racer, it was settled for him to test, though now the Spaniard makes the step up inside McLaren's team structure.

"I'm excited to be part of the McLaren team as one of their reserve drivers in 2023," Palou said in a statement.

"I can't wait for the involvement with next year's car.

"I look forward to continuing my development as a driver and I appreciate the trust McLaren have in me with this new role next year."

McLaren were involved in a dispute over new driver Oscar Piastri too, after the latter left Alpine amid a bitter fallout over his future.

The Australian will succeed Daniel Ricciardo for the team on a contract through 2024, and will partner Lando Norris, with McLaren yet to confirm the remainder of their reserve driver pool.
