iRacing Season 2 brings rain racing to four more cars. The Audi RS3 LMS Gen2 TCR, the Audi 90 GTO, the Lotus 49, and the Nissan GTP ZXT can all now run rain tires in 2026.
The Four New Rain-Ready Cars
Audi RS3 LMS Gen2 TCR
The Audi RS3 LMS Gen2 TCR is a brand new car in Season 2. It launches with rain support already built in, so TCR drivers have wet weather options from day one. TCR class racing is one of the more active road racing categories in iRacing, and the new car adds to that immediately.
Audi 90 GTO
The Audi 90 GTO is a well-known IMSA era car that has been in iRacing for several years. Before Season 2, it had no wet weather support. That changes with this update.
Lotus 49
The Lotus 49 is a 1967 Formula 1 car, and it is the most unusual entry on this list. Adding rain tires to a 60-year-old open-wheel car is a bold move. Wet laps in the Lotus 49 will be difficult and unpredictable, because 1960s F1 machinery in the rain offers very little forgiveness.
Nissan GTP ZXT
The Nissan GTP ZXT is an existing car that gains rain support in this update. Like the Audi 90 GTO, it has been in iRacing for some time. However, Season 2 adds wet weather capability to its feature set for the first time.
How iRacing Season 2 Rain Racing Works
Rain racing uses dynamic weather, so track conditions can shift from wet to drying and back during a session. Drivers must choose between rain tires and slicks based on current conditions.
Rain tires grip well on a wet surface, but they lose grip fast when the track dries. Slicks are the opposite. As a result, choosing the right tire at the right time is one of the key skills in wet weather racing.
iRacing tracks wet weather capability per car, so not every car can run rain tires. The Season 2 additions grow the list of cars that can.
Where to Find Wet Weather Races
Most official iRacing series run fixed, dry weather. Therefore, rain races are not part of the standard official schedule.
To find a wet session, check the Hosted Events section of the iRacing UI. Private hosts can enable dynamic weather when setting up a session. Some leagues also include rain rounds in their season format.
Hosted sessions are the best starting point for wet weather practice in iRacing.
iRacing’s Rain Expansion Continues
Each season update adds more cars to the wet weather pool. Season 2’s four additions continue a trend that has been building across several seasons, and the direction is clear.
iRacing is expanding rain racing across more car classes and more tracks. As the feature matures, more official series will adopt dynamic weather.
If you have not tried iRacing Season 2 rain racing yet, these four cars are a good place to start. The Lotus 49 is worth at least one session just to see what 1960s Formula 1 machinery does in the wet.
