We can see there will be day and night cycles, rain, and other new features. What can players expect in terms of immersion?

There is a fully dynamic 24-hour day and night cycle, which is determined not only by the time of day but also by the geographical location of the driving locations and the month of the year. Sky coverage will also affect lighting on track in real-time, since clouds are not a texture in the skydome, but are fully procedural meshes that generate shadows on the ground modifying the intensity of light and the shadow areas.

All this is visually perceptible, improving not only the driver's effectiveness but also the sense of immersion in the race.
