As part of a v1.10 update across PC, PlayStation and Xbox, several tweaks have been made to EA SPORTS F1 23 alongside the headline changes to a track layout and driver roster.
In order to accommodate construction work near the circuit, Turns 16-19 cannot be used for the 2023 race, and thus the Marina Bay Street Circuit will be slightly shorted as a temporary measure. This layout is now recreated within the game, significantly reducing lap times. In our testing, around seven seconds quicker per lap.
