Fernando Alonso will receive an additional 15-place grid penalty for new power unit components ahead of the Malaysian Grand Prix.

The McLaren driver had already received a 30-place grid penalty after taking a new power unit for Friday practice, with Honda upgrading the engine block and exhaust. The upgrades focused on reducing weight and making the parts more robust, but will be used fully by Alonso in Japan - Honda's home race - next weekend.

As a result, Alonso has reverted to a previous specification of power unit for the rest of the Malaysian Grand Prix weekend. However, the power unit has a new turbo and MGU-H, both of which are the ninth of each component and therefore carry an additional 15-place grid penalty, bringing the total penalty up to 45 places in total.

Team-mate Jenson Button was already using a previous specification of power unit but will now run the new lightweight exhaust - as Alonso will - for the rest of the race weekend.
