Numerous changes have been made to the Jeddah Corniche Circuit for 2023 "to deliver smoother, safer and even more exciting racing."
The changes, as revealed by RacingNews365.com, were made following complaints from drivers about the high speed nature at the track coupled with poor visibility.
The modifications were carried out last year in cooperation with racing circuit constructors Tilke GmBH after consultation with the FIA, F1 and drivers.

Improved visibility and corner cutting deterrents
The main changes are improvements to the driver sightline in specific areas of the track.
This includes the walls at Turns 14 and 20 being put back by 7.5m and 5m respectively, while the fence walls have been adjusted at Turns 8 and 10 for increased visibility.
One of the concerns of improving the sightline at these corners was the potential increase in speeds.
To combat this 'Rumble Lines' that slow cars down have been added at Turns 3, 14, 19, 20, and 21 have been added along with bevelled kerbs at Turns 4, 8, 10, 11, 17, and 23.
The final major change is at the Turns 22 and 23 chicane, where a re-profile has been made to reduce speeds by 50kph.
Changes to the DRS zone will also be made involving the adjustment of the detection and activation zones. These are expected to be confirmed by the FIA ahead of the weekend.
