How iRacing Heat Races Work

iRacing released more detailed information on their heat racing format that will be released very soon. I’m going to try to hit the major points in this article, and summarize the heat race process.

Heat races will take place in several different iRacing official series including short asphalt oval series, dirt oval series, and global rallycross. It’s unclear which official series will actually include heat races. Why not all dirt, GRC, and short track series? I don’t know. It seems a little cheap initially, but maybe iRacing wants to test it in a few series before full implementation. For now, it appears that heat races will be used in the Asphalt Super Late Model, one Winged Sprint Car Series, one Dirt Late Model Series, and the Class D GRC Series. It’s good that heat racing soon will be here, but the limitations are disappointing. Heat racing for hosted and league racing is said to be in the works, but “may get pushed back from the build.”

The Heat Race Format

Now let’s get to the actual race events. The flow of a racing event that includes heat races will typically follow the structure below. All of the stages listed will take place within a single iRacing session. You won’t need to disconnect, reconnect, or jump from server to server as you would in iRacing tournament sessions.

  1. Practice
    There will be a short open practice session that is designed to allow time for drivers to connect to the session in plenty of time for qualifying. Since this format will involve (theoretically, at least) many cars, the cars are split into “run-groups.” This allows everyone to practice yet keeps the number of car on the track at a reasonable number.
  2. Qualifying
    Session hosts will be able to select either closed qualifying or open qualifying. Closed qualifying is the same as lone qualifying, i.e., everyone qualifies alone at the same time. With open qualifying, everyone is on the track at the same time, but the cars are split into run-groups, similar to the split used in the practice stage.Qualifying is optional. If no qualifying stage is included, the heat race grids are formed randomly, as they would be in a pill draw.
  3. Heat Races
    Session hosts can specify how many cars transfer from the heat races to the feature race. Anyone who doesn’t transfer to the feature race is added to the unqualified drivers list. It is possible to set it up so that no drivers transfer directly from the heat races to the feature. The drivers from the heat races would still need to earn their way into the final by participating in one or more semi-final races.The grid for the feature is set from the heat races. The unqualified drivers will then advance to an optional consolation race or races.
  4. Consolation Races
    Consolation races can be stacked, meaning that the top drivers from each consolation race advance to the next consolation race. Only the top drivers from the final consolation race make it to the end of the grid for the feature race. If the consolation races are not stacked, the grids are filled directly from the unqualified drivers list. The top finishers from each consolation race advance to the end of the grid for the feature race.
  5. Warmup
    Only the drivers who are on the grid for the feature can participate in the pre-race warmup stage. Session hosts can leave out the warmup stage.
  6. Feature Race
    This is the final stage of the racing event. Only the drivers who have qualified for the feature will be allowed to participate.

Championship Points

iRacing will award championship points to all participants as follows:

iRacing Heat Race Points Structure

Points are awarded for the feature race and will follow the iRacing points system, in which the number of points awarded depends on the field size and the Strength of Field, or average iRating of the field. Only the driver who made it to the feature are considered when making these calculations.

General Information

  • You will have a fresh car at the beginning of every session.
  • The track state carries over from one session to the next.
  • Once hosted heat racing is fully implemented, the host can set up heat races for any type of track.

All in all, it sounds like a great heat race implementation and iRacing has pretty much covered every aspect in detail.

More Information About iRacing Heat Races

While iRacing apparently has not hammered out the details for their heat race format, there is some general information out there, obtained from iRacing staff, about how the heat race format will function, and this is what is planned.

Official races will still be split by iRating, but the splits will probably be bigger. Some drivers will be eliminated from the main through heat races. Those drivers will lose iRating. For example, if 40 cars sign up for a race, there will be two splits of 20 cars each. 15 cars will start each main. Five cars will be filtered out of each split as they run qualifying, heat and consolation races. Those five cars that are eliminated from each split will have two put their virtual cars on their virtual trailers and go virtual home. If you get through qualifying or heat races and decide the field is too strong, you’re motivated to stay in for the feature by the potential loss of iRating.

Just as it is now, there will be a maximum number of cars allowed for each split and that will vary by series. The number of cars allowed to start the feature will also vary by series. For example, maximum 24 cars per split, maximum 18 start the main.

Drivers will get new cars after each session. So if you crash in a heat or a consolation race, you start fresh in the next session. For Rookie classes I would expect to see unlimited fast repairs or resets, and one fast repair for D class races, at least in the feature races. That’s just a guess on my part but that’s the way it is now so I wouldn’t expect it to change.

iRacing Qualifying, Heat, and Consolation Race Points
iRacing Qualifying, Heat, and Consolation Race Points

The top qualifiers and finishers will receive a small number of championship points. Those points have no influence on the progression through the event. Points will always be scored in the feature and will be computed the same way they are now. Feature points vary based on the Strength of Field and the field size. Drivers that did not make the feature are not considered for the Strength of Field or field size calculations. Your points for the entire event will be used to determine which of your races are kept or dropped for the week. iRacing plans to use the USAC points system for qualifying, heats, and consolation races, as shown in the image on the right.

Heat race formats are planned for the 2017 Season 4 build coming in early December.
