Red Bull brings change to Verstappen's home Grand Prix: This is new on the RB21!

Formula 1 returns this weekend, as cars will be running on the Zandvoort track with the conclusion of the regular summer break.

In total, only three teams have decided to make changes on their challengers.

In terms of the frontrunner teams, only Red Bull Racing arrives with a new car part. The Austrian team has longer chord front wing flaps.

Because of the expected demands of the Dutch circuit, 'the extended chords on the flap elements' aim to 'increase the load available via angle', the FIA's car presentation document writes.

Alpine and Sauber also brought performance-specific updates for the Dutch Grand Prix.

The French team has new rear brake duct furniture to improve 'rear wheel wake management', while Sauber updated its rear brake duct vane design to 'affect the flow field around the rear of the car.'

In terms of the other seven teams, no updates were presented.

The first session of the day, FP1, will get underway at 12:30 local time (11:30 GMT)
