2024 Season 2 Release Notes [2024.03.05.01]
The iRacing 2024 Season 2 Release is here! After years of extensive R&D efforts and significant iRacer anticipation, rain and the Tempest Weather system have arrived. Together with multiple new product features, an improved UI, new content, and buckets of updates and fixes, the 2024 Season 2 Release is truly a landmark moment for iRacing. We'll start things off with a week of fun in Week 13, and then official competition will commence on March 12th at 0000 UTC!
Tempest, iRacing’s brand-new weather system that allows for rain racing, is fully operational and ready to manage the meteorological simulation demands of iRacing. The Road License Type is being split into Sports Car License Type and Formula License Type to provide separate competition ladders for drivers and to improve participation, competition, and matchmaking. We’ve added a fun New Driver Onboarding Experience that will help all new customers get onto the track immediately, set up their controls, get them racing with AI Drivers, and provide instructions and a guide for their next steps. We’ve also refreshed the look and feel of iRacing to improve navigation.
Three new cars have been added to the iRacing paddock, including the Dirt Micro Sprint (2 models), SRX, and Super Formula Lights. Three new tracks have also been constructed for iRacing: Algarve International Circuit (4 configs), Millbridge Speedway, and Misano World Circuit Marco Simoncelli (5 configs). A new configuration has also been added to Kokomo Speedway (Tires Out) to provide a different racing line, and a new configuration has been added to Lime Rock Park (School) as part of a new educational experience. Additionally, several pieces of content have been added to the iRacing base package, making them FREE for all iRacing members, including Dirt Micro Sprint, Circuit de Lédenon, Motorsport Arena Oschersleben, Snetterton Circuit, and Winton Motor Raceway.
The New Damage Model is enabled straight out-of-the-box on all three new cars, and it has been overhauled onto an additional FIFTEEN existing car models, including all GTE Class cars and all LMP1 Class cars.

Tempest Weather System & Rain
Time to keep an umbrella within arm’s reach of your iRacing SIM rig, rain is finally here!
The Tempest weather system has completely replaced the original weather system in all aspects.
Tempest in the iRacing Application:
- - Rainy weather may only be enabled at Sessions on asphalt Road tracks.
- - Rainy weather may only be enabled during Sessions that include rain-ready cars with either updated tires or a newly developed rain tire compound available for use.
- - - - With this initial release of Tempest, the Rain-ready cars are:
- - - - - - The IMSA GT3 Class stable of cars (Audi R8 LMS EVO II GT3, BMW M4 GT3, Ferrari 296 GT3, Lamborghini Huracán GT3 EVO, Mercedes-AMG GT3 2020, and Porsche 911 GT3 R (992))
- - - - - - The GTP Class stable of cars (Acura ARX-06 GTP, BMW M Hybrid V8, Cadillac V-Series.R GTP, and Porsche 963 GTP)
- - - - - - Toyota GR86
- - - - - - Dallara P217
- - - - - - FIA F4
- - - - - - Super Formula Lights
- - There are three methods to choose from for weather generation with Tempest: Static, Forecasted, and Timeline.
- - - - Static Weather: Select a few parameters, including cloud cover, track moisture, and temperature. Then, the weather in the Session will not change as time passes. When track moisture is set high enough, rain effects will appear and the cloud cover will be made overcast. However, the rain does not accumulate, drain, or impact the track state in any way - the track remains identical lap after lap.
- - - - Forecasted Weather: Select from a set of guidelines to build a forecast for the session, which predicts the likely weather that will be experienced in the event. Manually select parameters and iRacing’s Tempest system will run with them, including rain. Or you may select to use “Auto” Mode where iRacing will use historic weather data sourced directly from the selected track to craft a realistic day for you. Finally, you can mix and match, preview your results, and even randomly regenerate the whole thing if it’s not what you want.
- - - - Timeline Weather: Become a God of Weather and command the full power of Tempest! Craft a bespoke weather experience using customizable blocks of time throughout your event. Want it to start raining 30 minutes into your endurance race? You can do that. Want to re-enact a historic race’s weather down to the moment? You can do that, too! And so much more.
A new "View Forecast" button is now available for all Sessions that use Forecasted Weather.
- - This button allows you to view the expected weather information for any Session and provides details about which Weather Mode was used to create the session and if rain is possible.
- - - - Remember, for Forecasted Weather, this is a weather forecast and is not a guarantee - meteorology is not an exact science and the longer the Session is, the more opportunity Mother Nature has to shift the winds. However, the Session will respect specific options, such as setting chance of rain to be none. All the other options are hints as to what sort of forecast Tempest will build.
Road License Type Split
We are splitting the Road License Type into two new license types: Sports Car and Formula!
To encourage participation in both forms of racing and better reflect driver skill levels in each while matchmaking, iRacing will split its Road license type into two new licenses - Sports Car and Formula - with the 2024 Season 2 build. When the build deploys on Tuesday, March 5, all users will see the new license types displayed along their existing Oval, Dirt Oval, and Dirt Road licenses, while the Road license type will be retired.
- - When the license type split occurs, all iRacers’ current Road license iRating, Safety Rating, and MPR (progress towards promotion) values will be copied to your new Sports Car and Formula license types. All iRacers’ historical Road license data, such as stats, replays, awards, and other historical information, will be retained after the split with the Road (Retired) license label.
- - While iRating and Safety Rating will carry over from the retired Road license type to get things started, the following data will be collected from a fresh start under the new Sports Car and Formula license types: Race results and statistics (i.e., starts, wins, top 5s, etc.), Awards, Time Trial Rating (ttRating).
- - Due to the nature of the split, all league and hosted sessions scheduled for after the 2024 Season 2 build that use cars currently set for the Road license will be deleted and will need to be rebuilt. Sessions that fail to launch or are otherwise canceled are never charged to the users who create them.
- - The new license types will not affect how iRating and Safety Rating are calculated or what license requirements are for Official Series. There are currently no plans to split any other iRacing license types.
- - For additional information and recommendations, please see the iRacing Customer Support article here: Site faviconRoad License Type Split
New Racer Onboarding
A new feature has been added to iRacing specifically designed to give brand new users a ramp-up directly into iRacing with a guided first on-track experience. This feature allows users to select a preferred starting experience using either Oval or Road content, helps them setup and calibrate their controls, and walks them through a Practice and a Race experience using AI Drivers. It ends by directing the user to more information on the plethora of iRacing features available and a “getting started” guide for each!
Experiencing this new feature is defaulted to “ON” for all newly created iRacing accounts. This feature defaults to “OFF” for all existing iRacing accounts.
- - If you would like to experience this feature for any reason, perhaps you want some help with the basics, or you want to provide a great introduction to someone using your rig, a new toggle is now available in the Settings > User Preferences menu titled: New Racer Onboarding. Toggle this ON, and the next time you login, the experience will start for you!
Part of this feature also includes a new public-facing web page with introductory explanations and guides for using so much of what iRacing has to offer, including Test Drive, Time Attack, Spectating, Ghost Racing, Time Trial, AI Racing, and Official Racing. This guide also includes a New Racer Checklist with suggested activities that provide a progression for slowly increasing the difficulty and complexity of using iRacing.

General
A new styling and format have been applied throughout the core pages of iRacing!
- - This styling provides a more focused approach to possible activities, with nested levels on the left side. Your license class information is now in a vertical bar on the right.
- - Some modal windows, such as the Profile, have been converted to pages.
The iRacing application now uses a native Windows application title bar.
- - This enables all functionality granted by this feature, including window snapping and other quick Windows actions.
Fixed an issue with duplicate error toast notifications when a user gets disconnected. This fix also makes this error toast notification non-dismissable, but replaces it with a Success toast notification once the user is reconnected.
Dashboard
Fixed an issue where the SR value for the 30-Day Performance boxes was rounded to two decimal places.
Official Series
Fixed an issue where drivers with 0 championship points in a series could be displayed as having “NULL” points.
Team Racing
Acceptance of a team invite or application has been updated so the new team members are added to the list of people who may join the team in sessions for which that team is already registered. Before this change, new team members could not join the team in the session.
- - If a session uses the Declare Drivers feature, the new team members can only register as Crew.
- - If a session is not using that feature, then the new team members may be able to register as Drivers if they meet all eligibility criteria for the event.
Modified the appearance and language of the confirmation modal displayed when the user is informed they will be disqualified if the number of required team drivers is not declared.
Leagues
Fixed an issue with League Search where using an arrow button to navigate to additional pages would add a blank line at the top of the modal window when clicked.
Results & Stats
When an Official Series Session is run, the License Type used within the Session is recorded for statistical purposes instead of the License Type of the Official Series. For example, when an Official NASCAR Series goes to a Road track for the week, these Sessions will be cataloged as Sports Car License Type events for racing stats purposes.
For the Search function, the filter for “Season & Week” has been adjusted to filter for “Year & Season”.
Fixed an issue with the Results screen where the Back button only closed the window.
Paint Shop
A new sponsor, CONSPIT, has been added to the Paint Shop!
Fixed an issue where new customers could have their randomly assigned color pallet override the fixed paint schemes of some vehicles.
Fixed an issue where some car textures were being compressed even if the Graphics Options for shader level was set to High.
Profile
A new Certificates tab has been added to the Profile menu.
- - This tab features a data table displaying your earned certificates. A search field is also available for precise browsing. Each entry displays the date awarded and the results from the Session may be viewed. Finally, a button is available with each certificate to view and download the earned accolade.
Awards
Fixed an issue where a driver’s First Win Award was always displayed as an Oval Racing win.
Brand new Awards and Certificates have been added for the two new license types, Sports Car and Formula!
Unearned Road Awards have been retired and are now hidden.
Errors
Fixed an issue where the “Copy” button on Error Modal Windows did not copy anything to a user’s clipboard.
SIMULATION:
--------------------------------------------------------------
Tempest Weather System & Rain
The weather system used by iRacing has been completely reimagined and reengineered from the ground up. Original weather is no more - the Tempest weather system is now the only method for governing weather within the iRacing universe.
Tempest in the iRacing Simulation:
- - A new Weather Tab is now available in the Simulator, which provides current and forecasted weather information, including a Doppler radar map.
- - - - The INFO tab under TRACK CONDITIONS and the WEATHER tab have information on the current wetness level of the track.
- - A new F11 Weather Black Box has been added. This box provides some basic weather details and features a Weather Report button that will trigger your Spotter to give you the latest weather report details.
Rain Tires:
- - Tire interactions with wet surfaces and standing water have been engineered for realism. This includes lifting water from the track, channeling water through tire treads, casting off the water at various tire speeds and recollecting water in car body work, generating spray clouds, hydroplaning, and adjusting grip based on track surface roughness and wetness.
- - Not all cars are ready and equipped to handle the challenges a wet racing surface provides. Each vehicle and tire set is being developed independently for optimal performance and realism for rain driving. This includes cars that do not switch tires for rain driving.
- - The Ray FF 1600 is equipped with tires ready for rain driving straight out of the pit lane.
- - The following cars have a new set of rain tires available for use. They may be applied as any other tire compound change and follow the same rules:
- - - - The IMSA GT3 Class stable of cars (Audi R8 LMS EVO II GT3, BMW M4 GT3, Ferrari 296 GT3, Lamborghini Huracán GT3 EVO, Mercedes-AMG GT3 2020, and Porsche 911 GT3 R (992))
- - - - The GTP Class stable of cars (Acura ARX-06 GTP, BMW M Hybrid V8, Cadillac V-Series.R GTP, and Porsche 963 GTP)
- - - - Toyota GR86
- - - - Dallara P217
- - - - FIA F4
- - - - Super Formula Lights
Dynamic Track Experience:
- - The Dynamic Track system operates with water and moisture levels on the track surface. As water accumulates, track surface properties will change and racing behaviors should change as a result. This includes a wet driving line, puddle formation, moving water with tires and aerodynamic forces, track polish, and drying surfaces. Water can also leave the track surface entirely due to evaporation and drainage systems mapped to their real-world positions at all asphalt road courses. Be prepared for a vastly different driving experience!
The Race Control Experience:
- - The Race Control system is now aware of the saturation level of the track and will adjust reference lines and race rules accordingly.
- - The Pace Car is now aware of wet corners during pace laps and will slow appropriately.
- - The Qualifying Scrutiny System now tests against wet-aware speeds and adjusts expectations accordingly.
- - The Relative Black Box delta times are now adjusted for saturation levels.
- - The Fuel-to-End Black Box calculations now adjust for saturation levels.
- - Distance calculations for Blue Flags are now aware of wet area speeds.
- - Distance thresholds for slow car Yellow Flags are now aware of wet area speeds.
- - The telemetry value, "CarIdxEstTime" now uses a wet-adjusted lap time estimate.
- - The gain-time checkpoint, time yield, and course-cut penalty systems are all now aware of wet area speeds.
- - - - These three systems also scale correctly in sessions where dry laps have been set, and it then becomes wet, or visa-versa. The session pace scaling factors in condition variables as conditions change throughout an event.
AI Driver Experience:
- - AI Drivers are fully capable of driving in the rain and have received special training to prepare them for this day.
- - - - AI Drivers are ready for rain racing with all rain-ready vehicles!
Rain Visual Experience:
- - Rain visual effects include raindrops, wetness shaders, puddles and pooling, aerospray and splashing, vortex effects, mist, windshield and visor droplets, water reflections and ripples, lighting, and so much more.
Rain Auditory Experience:
- - A wide sampling of ambient rain and environmental sounds for rainy weather have been added, and their levels have been optimized.
- - A new audio level slider for rain effects has been added to the Options Screen.
Rain Telemetry variables and data have been added!
- - Live var 'WeatherType' extended to pass back a new irsdk_WeatherDynamics define rather than just constant/dynamic.
- - New live var 'WeatherVersion' that passes back a new irsdk_WeatherVersion define.
- - New live var 'Precipitation' that returns the amount of precipitation seen at the start/finish line.
- - Session string WeekendInfo:TrackWeatherType: extended to cover dynamic weather.
- - Session string WeekendInfo:TrackSkies: extended to cover dynamic weather.
- - New Session string WeekendInfo:TrackPrecipitation: that returns initial precipitation at start/finish line at start of session.
- - Session string WeekendInfo:WeekendOptions:WeatherType: extended to cover dynamic weather.
- - Session string WeekendInfo:WeekendOptions:Skies: extended to cover dynamic weather.
For setup-builders and testing, please note: weather seed generation for Static Weather mode always generates the exact same weather seed when all adjustable parameters are identical between any two Sessions at the same track. This allows for perfectly repeatable and predictable Session conditions to be run at the same track when using the exact same Static Weather parameters.
Anti-Cheat Software
The Anti-Cheat Software used by iRacing has been adjusted from EasyAntiCheat to Epic Online Services.
Updater
Adjusted some processes for the Updater which should now prevent an issue where the updater could fail to launch if it was run a second time immediately after having just completed an update.
Simulation
Some optimization work for data hashing has been completed, reducing visual stutters that could occur whenever another player joins a Session you are in.
Fixed an issue where the Simulation closed on Alt+F4 key-release instead of key-press. This could unexpectedly close the Simulation if it gained focus immediately after another program that Alt+F4 ended on key-press.
Fixed a Simulator crash issue that could occur during Cooldown in Hosted Sessions if the purchased time had already expired by that stage.
Connectivity
iRacing is now participating in evolving networking standards that are designed to allow latency-sensitive applications to identify their network traffic as such. iRacing joins other organizations like Google, Apple, NVIDIA, Valve, and Comcast (among others) in this standard. L4S (Low Latency, Low Loss, Scalable-throughput) uses an underlying network standard known as ECN (Explicit Congestion Notification) to request preferred treatment on the network for real-time applications (like Voice over IP, and gaming). Network traffic adhering to this standard can benefit from reduced latency and jitter from queueing delays, and reduced packet loss during congestion.
A new Explicit Congestion Notification (ECN) meter, or “E Meter,” is now displayed in the Simulator.
- - The "numeric" version of the E Meter displays a green "OK" when we're not responding to congestion. The graphical E Meter remains empty when things are normal, just like the Q Meter is when there's no packet loss.
- - While the congestion response is active, the corresponding side of the E Meter will show a red "CE", or a full red bar (left side for download, right side for upload).
- - - - If upload congestion is present, others will get your car positions less frequently. If download congestion is present, you'll receive others’ car locations less frequently, and if there are lots of people in the session, you might end up seeing fewer opponent cars - just as if you had your account's "Connection type" set to a lower bandwidth amount.
Voice chat is also subverted during an Explicit Congestion Notification (ECN) congestion response.
- - During a CE response on the Sim's upload path to the server, we will now disable recording/sending voice chat. When Push-to-Talk is activated, the notification will indicate that you can't send voice chat due to CE. No notification of your attempt to talk is saved to the Replay.
- - During a CE response on the Sim's download path from the server, the server will inform you that someone is speaking but will not send the actual voice data to you. The notification that someone is speaking is altered to replace the speaker's name with a message indicating that they are muted due to CE. The notification is saved to the Replay, and is shown when playing-back the Replay with the "Voice Chat Review" option enabled.
Cars
The starter motor torque curve has been improved for 3-cylinder cars.
- - This should help with issues where some of these cars fail to start at high altitudes.
The starter motor will now continue cranking while the ignition delay is counting down.
Fixed an issue that could occur where the Traction Control (TC) system was intervening incorrectly for some cars with certain engine braking throttles.
Removed an ancient legacy piece of code that provided roughly a 1 in 1,000,000 chance of catastrophic engine failure at any time for no reason.
Fixed a calculation issue that could occur with oil pressure values that could approach zero but never actually hit zero.
Tires
Grass slipperiness has been increased slightly for both dry and wet situations.
Off-track rolling drag forces have been updated, especially when a car is also under braking.
A tire’s off-track surface depth detection has been updated. As a tire gets farther from a racing surface, the effects of the off-track surface will be stronger as the sand or dirt becomes looser and deeper.
Dynamic Track
Improved the accuracy of the Current Track Temperature readout in the Info panel.
Race Control
As part of the 2024 Season 2 Release, our Race Control developers put together a special training curriculum designed for iRacing’s long-time pace car driver. We felt it was time to impart on him some of the lessons learned from developing so many successful seasons of AI Racing School. As a bonus tidbit, and as a result of the class registration process, we finally learned the name of our long-time mysterious pace car driver: Fred!
- - Fred has completed a pair of classes focusing on how to pace smoothly, especially for tight corners, chicanes, and for leading a 2-wide pace field. Fred is now aware of tight corners and will slow gradually into them and accelerate at a reasonable rate out of them in order to accommodate the field. Fred is now also aware if he is leading a 2-wide pace field or if it is a large field in general, and will adjust the pacing speed to accommodate.
- - Fred completed mandatory training on what is and what is not the pit lane. Fred sometimes forgot he was already out of the pits and on the race track, but continued to obey the pit speed limit.
- - Fred was also selected to complete a course focusing on collecting the pace field in difficult situations. Fred can now pick up the pace field if a Caution comes out when the race leader is very close to the Start/Finish Line or pit entry/exit. He has now kicked his old habit of tearing out unreasonably quickly, or doing a full hot lap, before settling in to lead the pack.
Fixed an issue where the penalty value displayed for gain-time checkpoints could be incorrect.
Team Racing
Fuel usage data is now copied when changing drivers. If the previous driver has useful data and the new driver does not, the new driver will receive the previous driver's fuel data. This should also fix cases where teammates cannot toggle the Auto-Fuel checkbox for the new driver.
Dirt Racing
Some racing dirt surface parameters have been adjusted which should provide both a more grounded feel for tires on dirt, and slightly slow down racing in the slick.
Rallycross Racing
Fuel tanks for Rallycross cars have been adjusted to 80 liters.
AI Racing
iRacing’s AI Racing School led a double curriculum for Winter 23’ - 24’ where much of the time was focused on driving in wet conditions. Let the AI Drivers be the first to tell you that driving in the rain is tough! But they have persevered and have earned their first stripes for rain-driving capability.
- - This season’s racing curriculum literature included:
- - - - The True Tire Temperature Test: Tepid to Torrid

Graphics
Depth resolve buffer format has been optimized. This change impacts SSR, SSAO, heat haze, SMAA, and DOF to process faster.
Screen Space Reflections (SSR) rendering methodology has been updated. Note that this feature defaults to OFF. For rain, it is worth exploring how this feature performs on your machine across its two settings: Low and High. This can be set independently for Drive and Replay, which gives you the ability to customize the graphics vs. performance impact based on the scenario.
Particle effects may now be down-sampled to half or one-quarter resolution based on the performance needs of the system. This provides a potentially massive improvement to processing speed without entirely sacrificing appearance.
- - Quarter resolution particles are always enabled at a minimum.
Improved the rendering look and performance of the Dynamic Track Surface for rain.
A variety of additional background characters should now have their undivided attention drawn to the player car and/or focus object.
Headlight intensity has been increased overall, in both wet and dry conditions. This helps significantly in wet conditions, as everything is generally darkened, and improved exposure intensity for night racing.
Trees populated via the SpeedTree system (those at newer tracks) have had some of their lighting and shadow properties adjusted.
Tire skid mark generation strength has been adjusted.
Fog rendering effects have been updated.
PopcornFX has been updated to a newer version.
Memory allocation for PopcornFX has been updated.
Fixed an issue where the graphics Auto-Config did not properly save the chosen display device to the “settings.ini” file. This fixes an issue for users with multiple monitors using full-screen mode.
Audio
Some general PA commentary has been added to Japanese tracks.
A new undertray scrape sound has been added to some cars.
Pit Stop
Auto-Fuel now re-enables itself on pit exit if “autoFuelDefaultEnable=1” even when “autoResetPitBox=0”.
Auto-Fuel is now disabled and grayed-out when you are no longer being scored, such as when the Race is over, or you have been Disqualified.
Spotter
Spotter messages concerning weather conditions, rain, track moisture state, and rain tires have been added.
A new spotter message has been added for Rallycross Racing, reminding the driver to take the Joker Lap if the race is about to end and the driver has not taken it yet.
A new spotter message has been added that lets the driver know Race Control and Scoring have ended. Time to burn it down!
A new spotter message has been added that reminds the driver that the car is out of fuel if the car is out of gas and cranking or trying to start.
Incident messages involving car contact will now specify which car was contacted. For example, the chat window will now display, “Car #5 Contact…” instead of only “Car Contact…”.
The default Spotter and Crew Chief volume level has been reduced.
Fixed an issue where the Spotter would inform you that the car ahead of you had gone off-track, and then after you passed the car, he would inform you again that the car behind had gone off-track. The Spotter now knows this is in fact, the same car.
Fixed an issue where the Spotter could deliver an incorrect damage assessment to team members when towing begins.
Fixed an issue where the Spotter would tell you how many tire sets you had left in Sessions that did not have tire change limits.
Fixed an issue where the Spotter would call out how far away your pit box was while you were being towed.
Options
The "Network:" tooltip has been updated to include a description of the new “E Meter” for Explicit Congestion Notification (ECN).
A new option to enable the high-contrast mouse cursor has been added to the Options screen, and the high-contrast mouse cursor appearance has been updated.
Controls
A new slider has been added to the Options screen that lets you limit the brake output range.
- - This allows users to long calibrate their brake pedal without editing the “joyCalib.yaml” file.
A new dual-clutch bite-point feature has been added.
- - Users may now set the maximum range of the clutch pedal at launch time to some value below 100% and then use a separate button or analog paddle to hold the clutch at 100% until it is time to launch. Finally, using the primary clutch, users can then roll off the clutch as usual but with more precision. This opens up dual-clutch style launches to all players, even ones with only a single clutch pedal, and helps level the playing field.
- - - - This feature does not automate a launch for you - you still have to roll the clutch off manually. However, it will help you set the initial bite point during launch for more precision.
Improved default force values for Asetek brand racing wheels have been implemented.
The Fanatec API has been updated.
Support has been added for Simmagic P-HPR haptic pedal reactors.
Fixed an issue where warning messages could be generated about unknown wheels.
Active Reset
The saving and loading of the track state when Active Reset is triggered has been disabled.
Fixed an issue where the screen would change camera views to a track-side camera for a tick whenever Active Reset was triggered. Now, the camera view remains in the cockpit, and no visual flickering should occur.
Sporting Code
The Sporting Code has been updated to reflect the Road License Type split into Sports Car and Formula.
A new section, 6.11.1. has been added to document proper Rain Racing procedures.
New Glossary entries have been added for: Formula, Full Course Caution, Local Caution, Rain Race, Restart, Sports Car, and Tire Compound.
Fixed an issue with the incident penalty tables in section 3.5.

Dirt Micro Sprint Car
NEW CAR!
- - The Dirt Micro Sprint Car, a new Dirt Oval car, is now available for testing and racing on this environment!
- - Want to get your start on the dirt racing ladder? The Micro Sprint is your first step. One of the fastest-growing small car classes in America, don't be surprised if you see many of the drivers competing in these small yet nimble machines become the future stars of pro racing. Whether it’s in a weekly racing series, traveling championships that run across America, or major events like the Tulsa Shootout, they're a fun, affordable way to get out on track and have some fun! Micro Sprints mostly race on small tracks, such as the quarter-mile Millbridge Speedway in North Carolina. Equipped with a 600cc engine that produces more than 160 horsepower, they've got enough power for young racers to learn the skills they need to step up, but are approachable enough not to overwhelm them. Micro Sprints can be run both with and without a wing, and on iRacing, you'll have the opportunity to try both!
- - This car has two models available, Winged and Non-Winged.

SRX
NEW CAR!
- - The SRX, an asphalt and dirt Oval car, is now available for purchase and racing!
Legendary racers Tony Stewart and Ray Evernham turned the world on its head when they announced the creation of the Superstar Racing Experience in July 2020. The concept married elements of past all-star racing series with senior tour golf and weekly short track racing: six straight weeks of action in the summer on a mix of paved and dirt ovals, featuring an eclectic mix of racing champions, rising young stars, and even some local heroes who earned their way onto the grid for one shot at glory with the pros. Designed from the ground up by Evernham and built by Fury Race Cars, the SRX car is a stock car unlike any other. Equipped with 700 horsepower Ilmor V8s and a high spoiler straight out of the 1970s, these cars were built for lots of power and low downforce, making them a challenge to drive. Like in the real world, iRacing's SRX car is equipped with paved and dirt tires, so you can race it on whichever ovals you'd like!

Super Formula Lights
NEW CAR!
- - The Super Formula Lights, a new Formula car, is now available for purchase and racing!
Super Formula Lights is the final step that drivers face on the Super Formula ladder before heading into the top-level series. With a history of taking its basis from global Formula 3 regulations, for 2024, the series will feature Dallara's latest addition to one of the most impressive portfolios of open-wheel cars in racing history. Known as the Dallara 324, the current Super Formula Lights car is a successor to the 320 model that the series featured over the previous four years. Aside from chassis and aerodynamic upgrades, the new car sees a big departure from years past as it moves to the first spec engine in series history. It features a turbocharged, three-cylinder, 1.6-liter Toyota TGE33 engine developed by TOM'S, capable of producing roughly 275 horsepower. This is the same caliber of machinery that most of the world's top young open-wheel racers to go through as they climb to the highest level, so don't underestimate it!

TRACKS:
--------------------------------------------------------------
Algarve International Circuit
NEW TRACK!
- - Algarve International Circuit, an Asphalt Road track with 4 configs, is now available for purchase and racing!
Commonly known as Portimão for the city in which it's based, Algarve International Circuit is one of Portugal's premier racing facilities. Breaking ground in early 2008 and opening later that year, it has boasted a full calendar of global and national events ever since. Twice the home of the Portuguese Grand Prix, the track has also hosted the 6 Hours of Portimão, numerous TCR events, and various other motorcycle, open wheel, and sports car races in that time. A lap of Portimão is marked by heavy elevation changes throughout its 4.653 km (2.891 mile) layout. These big slopes mix with a varied selection of tight and sweeping turns to produce one of the most old-school feeling laps out of any circuit built in the 2000s. You'll have the chance to sample all of its variations through both its Grand Prix and Moto configurations, each of which are available both with and without chicanes.

If your favorite NASCAR driver lives in North Carolina and likes turning laps on dirt for fun between Cup Series weekends, you've probably seen Millbridge Speedway. If they've got a kid who wants to race, too, you've definitely seen it. Whether it's midgets, micro sprints, or box stocks, the midweek entry lists are typically packed with talent at the miniature dirt oval just half an hour from Charlotte Motor Speedway. Millbridge is owned and operated by the Burnett factory, who first became involved with the track in 2011. Their efforts have taken the quarter-mile bullring from nearly becoming a "lost speedway" to cult status among those who know it well. For the authentic Millbridge experience, take the Dirt Micro Sprint out for a spin, and you'll see why it's such a beloved track among its regulars.

Misano World Circuit Marco Simoncelli
NEW TRACK!
- - Misano World Circuit Marco Simoncelli, an Asphalt Road track with 5 configs, is now available for purchase and racing!
Over the past 50-plus years, Misano World Circuit Marco Simoncelli has established itself as one of Italy's most fun racing circuits. Opened in 1972, it has seen a handful of reconfigurations in its half-century of operation, most recently settling on its current 4.226 km (2.626 mile) Grand Prix layout in 2008. In 2012, the track was given its current name to honor late motorcycle racer Marco Simoncelli, who grew up in the area and ascended to the top levels of the sport. The current Misano layout hosts everything from Grand Prix motorcycle racing to Formula 4 and numerous sports car championships. Here on iRacing, you'll sample five different layouts, ranging from the current Grand Prix and Truck layouts to two historic GP configurations and even a short Club circuit.
