A full day/night cycle and weather
Project CARS is one of only a few racing games to feature a day/night cycle in addition to a weather system. As seen in the screenshot above, both can be very precise. If you want to race in April at 12:00PM during a Thunderstorm, you have that option. Bright skies, light rain, and storms are on full display.
rnThe day/night cycle makes for some spectacular views during races, especially in cockpit view. Also, weather isn't static. You can actually see the clouds move through the sky, and with them the weather they bring. You'll watch rain trickle down before stopping, and overcast skies clear up during longer races.
