Mercedes plans to introduce a sixth upgraded power unit for its W17 cars later this season, utilizing Additional Development and Upgrade Opportunities regulations. The team is eyeing the upcoming races in Austin or Mexico to deploy the new components.

Future engine integration remains a critical factor for the championship standings as Antonelli maintains his lead over Russell.
