iRacing Season 3 build notes, new content announced

With the release of the new iRacing forums on Monday night, the details for iRacing’s 2021 Season 3 build were also announced. All of these changes we’re implemented on Wednesday at 8:00 a.m. ET / 1200 UTC / 1:00 p.m BST. 

We knew of a few things that were in store, like the new Porsche 911 GT3 R, the Formula Vee rookie car and the recent announcement of the 1987 NASCAR Stock Car updates, but that was just the tip of the iceberg for what’s coming in Season 3. 

For NASCAR fans, the addition of Nashville Superspeedway has been announced, while for Formula 1 fans, the Red Bull Ring will be joining the service in three different configurations. 

I know for some of us on the NASCAR side, it was expected that we’d get the new Nashville track with its addition to the 2021 NASCAR schedule. The Red Bull Ring is a fantastic road course in Austria that was popular enough to get two F1 race dates due to the COVID-19 pandemic last year, so we’ll likely see that on the upcoming schedule for the new Dallara iRacing Grand Prix Championship qualifiers in the TBA slot. 

Other important notes include a fully updated SCCA Spec Racer Ford, now in its Gen3 edition, a new and free Volkswagen Beetle Lite for the Rallycross / Dirt Road ladder, more adjustments to the New Damage Model as it is also added to the Formula Vee and Street Stock, some particle effect updates for smoke, dust and sparks, and a new Four-Tire Detection system at select tracks to make off-road incident getting more forgiving. Oh yeah, AI got a decent update too for those who’d rather go offline and practice.

Honestly, there is a TON in the changelog for Season 3, basically something for everyone on the service. I feel like I’ve barely scratched the surface. Let us know what you’re most excited about that’s arrived in Season 3 in the comments or on social media. 

IRACING 2021 SEASON 3 BUILD NOTES 

*Updated as of 9th June 2021 – Changes are IN BOLD and ITALICIZED

iRACING UI

Find Sessions for Content 

  • Each Car and Track info window now features a new tab, Find Sessions. To get to the Car or Track info window from anywhere in the UI, click the three dots icon next to a content and select “Car/Track Info” 
  • – – This tab is separated into three sections which each display a list of all available sessions that use this piece of content. This includes: Official Sessions, Hosted Sessions, and Time Attack. 
  • – – From this window, you can browse all available sessions, navigate directly to the associated Series to learn more, or even join the sessions right away! You may also use select Filters and Tags to curate the list of available sessions to your tastes. 
  • – – This tab is available for ALL pieces of content, even items you do not own. This makes it very easy to learn how a piece of content is used before you purchase it, and it allows you to jump right into events using a favorite piece of content. 

Interface Images 

  • All images in the iRacing UI that previously showed a Member’s in-Sim paint scheme will instead now show any available custom paints present on the file system. 
  • – – This applies to cars, suits, and helmets. 
  • – – This should work for a Member’s own paints as well as displaying other Members’ paints. For example, seeing another Member’s custom helmet on their profile. 
  • – – As a reminder, custom paints should be placed in the “My Documents/iRacing/paints” folder. Helmets and suits are in the base directory and cars are in their respective subdirectories. 
  • Car images will automatically be loaded when the iRacing UI launches. 
  • – – This should minimize the appearance of car images “popping in” when a large number are shown on a page at once. 

Series Racing 

  • Fixed an issue where the Time of Day setting was not being correctly preserved when creating Test Drive events or Hosted Sessions from a Series event. 

Team Racing 

  • For the Declare Drivers feature for events using the “Drive Fair Share” rules, Teams may now update their pending Declared Drivers list prior to the start of the Race Session. 
  • – – Drivers in the list must still be team members that are eligible to drive for the session. 
  • – – The Declared Drivers can only be altered for sessions which have not launched and are currently open for registration. 
  • – – The list cannot be changed for Practice or Hosted Sessions, or Race Sessions after the Session starts. 
  • – – Any team admin or the team member who registered the team can update the list of declared drivers. 

Hosted Racing 

  • Users now have the ability to select specific “Series Branding” for supported cars and tracks in Hosted and League Sessions.
  • – This can be configured by going to the “Race Options” step of “Create a Race” and selecting a Series from the dropdown. Currently, the IMSA series branding is supported for this option on some of the P2, GTE and GT3 class cars.
  • For Open Practice Only events, multiple setups may now be selected for use. For example, this allows users to select both Qualify and Race setups for practicing.
  • Fixed an issue where users were unable to change the selected track for their Session if they had enabled Short Parade Laps prior to attempting to change the track.
  • Filtering the available Hosted Sessions to achieve no results now correctly displays the warning “No Data”.

AI Racing

  • Some additional race options have been added for AI Racing, including:
  • – Short Parade Laps
  • – Wave Arounds
  • – Do Not Count Caution Laps
  • Fixed an issue where loading into an AI Session using a default class-based Opponent Roster would break the loading screen.

Paint Shop 

  • Textures for driver heads with ponytails have been updated. 
  • The McLaren MP4-30 interface model has been updated to better match the in-Sim version. 
  • The RYCO logo has been updated. 

General 

  • Fixed an issue where new users could load into an empty user interface. 

MEMBERSITE: 

Auto-Launching The UI 

  • The home page no longer half-loads when you select to cancel opening the iRacing UI. 

Promotions 

  • Fixed a button layout issue. 

FORUMS

New Forums 

  • New iRacing Forums: https://forums.iracing.com/ 
  • All new posts, discussions, and announcements from iRacing will only be made in our new forums. 
  • The original Membersite forums will remain available through June 23rd. Then they will enter a read-only state for the foreseeable future. 
  • The Private Message system will also remain intact until further notice. 
  • We will be providing an OAuth2 API for third-party development in the near future as well. 

SIMULATION

Connectivity 

  • Improved the reporting and handling of dropped connections. 
  • – – These changes will NOT fix bad network connections, but the messages shown as a result of these changes may give a bit more detail as to what went wrong. In some situations the amount of time it takes for a dropped connection to be cleared will be reduced, so a user may be allowed to reconnect more quickly. 

Cars 

  • Up to 8 different car models may now be used when creating Hosted Sessions.
  • Engine oil cooling has been adjusted to increase temperatures at lower engine RPM. Higher engine speeds are not impacted by this change. 

Tracks 

  • All track collision meshes have been regenerated. 
  • A variety of visually updated tire stacks and tire wraps have been added throughout iRacing tracks. This rhyme was unintentional. 

Race Control 

  • A new mode of off-track detection has been created, “Four-Tire Detection”. 
  • – – Our current off-track detection system checks for whether or not half or more of your vehicle has traveled beyond a racing surface boundary. The new four-tire detection system checks for whether or not all four of your vehicle tires have traveled beyond a racing surface boundary. Since the four-tire detection system requires more of your vehicle to be off of the racing surface before administering a penalty, this system is more forgiving. 
  • – – The four-tire detection system will be deployed on a case-by-case basis. With this initial release, the four-tire detection system is currently active at some areas of Circuit de Spa-Francorchamps and Red Bull Ring. The four-tire detection system will be applied to additional tracks and areas as we continue to collect feedback and data from our members. 
  • – – Any track that is utilizing the four-tire detection system will feature a new “Rules” tab in the in-Sim interface. This new tab will detail where the four-tire detection system is active at the track. 
  • Fixed an issue where closed pit exits could cause a black flag for drivers on a parade lap when the field starts in pit lane. 

Dirt Racing 

  • Opponent tires on dirt surfaces should appear to be touching the ground better, particularly for slopes, bumps, and divots. 
  • All dirt versions of stockcar tires have been reverted to an earlier version. 
  • – – This change affects the following vehicles: 
  • – – – – ARCA Menards Chevrolet Impala 
  • – – – – NASCAR Cup Series Class Cars 
  • – – – – NASCAR Gander Outdoors Series Class Cars 
  • – – – – NASCAR Next Gen Series Class Cars 
  • – – – – NASCAR Xfinity Series Class Cars 
  • – – – – [Legacy] NASCAR Cup Series Class Cars 
  • – – – – [Legacy] NASCAR Nationwide Chevrolet Impala – 2012 
  • – – – – [Legacy] NASCAR Truck Chevrolet Silverado – 2008 
  • – – – – [Legacy] NASCAR Xfinity Series Class Cars 

Rallycross Racing 

  • Fixed an issue where the high rpm launch rev limit in the rallycross cars would prevent the gearbox from downshifting lower than 3rd gear when stationary. 

AI Racing 

  • AI Drivers are now able to pilot the following additional vehicles: 
  • – – Porsche 911 GT3 R

Race Admins 

  • A new race admin command has been added that can modify the number of laps a Caution or Parade will be: 
  • !pacelaps (or !p for short) <+n|-n|n> 
  • Add +n laps to caution length, or remove -n laps from caution length, or set caution to “n laps to green” at next crossing. 
  • The caution lap length can’t be adjusted until the first full caution lap is completed, since the caution length is not finalized until then. 
  • The number of parade laps may be adjusted immediately, just as cars start driving. 
  • !yellow is primarily intended for throwing a caution, but can still be used to delay an upcoming start/restart by 1 lap if used during the 1 to Green lap, which would be equivalent to !pacelaps +1. 

New Damage Model 

  • The New Damage Model has been enabled for the following vehicles: 
  • – Formula Vee 
  • – Street Stock 
  • The duration during which detached parts from opponent vehicles are collidable has been shortened significantly. 
  • – This should help reduce the possibility of hitting debris generated from local estimates of collision damage in a high latency environment. 
  • – The duration for yourself and your own car parts has not been reduced. 
  • Tire side-wall properties for some vehicles have been adjusted to differ from tire tread properties. These changes should allow more realistic tire-to-object and tire-to-tire contact based on the part of the tire(s) making contact. 
  • – These tire property changes have been enabled for the following vehicles: 
  • – – – – ARCA Menards Chevrolet Impala 
  • – – – – Audi RS 3 LMS 
  • – – – – Dallara IR18 
  • – – – – Indy Pro 2000 PM-18 
  • – – – – Skip Barber Formula 2000 
  • Fixed an issue where some cars were getting repeatedly reset in the pits, and appeared to be bouncing around as a result. 
  • When a spring damper was broken it was possible the wheel could hit the hyper extension limit if it was set fairly low. Whenever the hyper extension limit was exceeded the code was resetting the car while in the pits, without fixing the hyper extension, resulting in a bouncing-reset loop. 
  • Some curbs used on Rallycross tracks have been updated to prevent devastating blows to cars utilizing the New Damage Model. 

Original Damage Model 

  • Fixed an issue where vehicles that have the capability to run the New Damage Model were not having damage scrape textures appear when running with the Original Damage Model. 

Rendering 

  • Fixed an issue where specular highlights were not rendering brightly enough, especially on the track surfaces and cars.  
  • Fixed an issue where the illumination of the world often flickered in brightness as the sun moved, especially during sunsets. 

Visual Effects 

  • Smoke may no longer be disabled via the graphics options. 
  • Tire smoke and dust have received an overhaul! 
  • Smoke and dust volumes and sizes have been tuned based on the moisture levels in the environment. 
  • Smoke blending has been improved. 
  • More lingering dust should be visible towards the end of a dust-cloud’s life cycle. 
  • Dust particle volume has been increased during dirt racing events.

  • Water shaders have been updated for more realistic behaviors including slower speeds along the shores and improved roughness. Water reflections have also been improved 
  • Fixed an issue where smoke effects were not appearing for the player car during Lone Qualify Sessions. 

Audio 

  • Road debris sound levels and variations have been improved. 

Pace Car 

  • The Sedan Pace Car may now be selected for use at any and all track types. 
  • The pace car driver has completed a rigorous course in stunt driving with this vehicle, and has passed all final exam maneuvers with flying colors. 
  • After some extensive tutoring on the states of matter, the Pace Car driver is now less apt to drive through solid walls. 
  • Fixed an issue where the Sedan Pace Car’s headlights would incorrectly be lit while parked at night tracks. 
  • Backfire effects have been removed from the Sedan Pace Car. :’( 

Spotter 

  • The Italian spotter packs has been updated, thanks to Renzo A. Olivieri and Marco Arcidiacono. 

Cameras 

  • More camera tool controls can now be mapped to an analog axis on a joystick. 
  • The “show camera” mode is no longer persistent, and will now turn itself off on the next restart of the Sim. 
  • Blimp camera option minimum allowable values have been reduced to nearly 0. 
  • Fixed an issue with cameras’ “aim at group” logic that could sometimes cause a camera to shake or shudder. 

Controls 

  • Joystick calibration routines have been updated so that all control types should be able to calibrate, including combined pedals that operate in the opposite direction of the industry norm. Mapping separate functions to each half of a joystick’s axis should be greatly improved as well. 
  • Support for the display on the new Thrustmaster SF1000 wheel has been enabled. You can turn this on and off with the “Control LCD wheel displays” checkbox in the Sim Options menu. Tire data is not sent to the wheel, other than core temperatures and wear being updated when you stop in your pit box. This matches the rest of the Sim where no real time tire info is displayed. To make this work you will need to be on the latest version of the Thrustmaster driver (2.TTRS.2021 rc29), and you will need to update your drivers and firmware to enjoy the full support of SF1000 in iRacing. 
  • Logitech keyboard back-light support has been re-enabled. 
  • – You will need the latest version of Logitech GHub or Logitech Gaming Software. 
  • Support has been added for the Razer Chroma RGB Controller and other Chroma Link enabled devices in the Razer Chroma keyboard lighting effects. 
  • Fixed an issue where the second brake and second throttle controls were disabled for some vehicles. 
  • Fixed an issue where some analog controls could never achieve a “0 input” value. 

Telemetry 

  • A new session string value, “CarClassEstLapTime” has been added. 
  • – This value indicates the estimated lap time for every car in the session. This value matches the existing value, “DriverCarEstLapTime” entry for the player’s car. 
  • New telemetry values, “CarIdxFastRepairsUsed” and “PlayerFastRepairsUsed” have been added. 
  • – These values log how many fast repairs each participant has used in the current session. These only report on sessions where there is a limit on the number of fast repairs. 
  • ABS brake engagement is now logged to telemetry as the boolean, “BrakeABSactive”. 
  • – This value is true if either the car physics ABS is active or the Driving Aid ABS is active. The car physics ABS now drives the LFE bass shaker just like the driving aid did previously.

SCCA Spec Racer Ford – A FULLY UPDATED FREE CAR! 

  • The SCCA Spec Racer Ford has been fully updated to the Gen3 version! 
  • This change includes a brand-new tire spec, new digital dashboard, increased horsepower, reduced vehicle weight, and a 6-speed sequential gearbox. 
  • – The notion of competing in a class of identical race cars so that driving skill is paramount and the size of one’s checkbook doesn’t matter is second nature to iRacers – it’s a central theme of the iRacing.com community. But the concept, originally borrowed from one-design sailboat racing, is rapidly gaining currency in motorsport with classes ranging from Spec Miata to Star Mazda and even to IndyCar, where every team races the same chassis/engine combination. The original successful one-design auto racing class, first introduced a quarter-century ago in Sports Car Club of America amateur racing and still going strong today (after a few universally-applied modifications along the way), is Spec Racer Ford. Manufactured and marketed by SCCA Enterprises (a subsidiary of SCCA, Inc.) the Spec Racer Ford is a purpose-built sports/racing car. With more than 850 cars manufactured, it is one of the most prolific dedicated racing cars in the world, and has served as the launching pad for a number of drivers who have gone on to substantial success in motorsport, including racer-turned-broadcaster Dorsey Schroeder. The car was developed and originally manufactured by Renault/Jeep Sport USA. An initial proof-of-concept was assembled using the longitudinal engine-transmission package from the Renault LeCar, but that vehicle was written off in testing at Road Atlanta and a more practical successor was then developed using the transverse Renault/AMC four-cylinder Encore powertrain. Known as the Sports Renault, that vehicle, which looks virtually identical to today’s SRF, made its debut in SCCA club racing in 1984. The car was sold to competitors in kit form, but to facilitate technical support and give buyers a turn-key option, SCCA established a regional network of sales and service dealers, a concept that under the name Customer Service Representatives, remains a key element in the success of the class today. With AMC sold off to Chrysler and Renault sponsorship withdrawn in 1989 after a fleet of hundreds of cars had been put into service, the class was renamed Spec Racer and the club took over responsibility for manufacturing and supporting the car. Five years later, with the original Renault engines and transmissions growing scarce, SCCA began a program to gradually shift the fleet to a 1.9-liter four-cylinder Ford engine and five-speed transmission, and for several years the club supported two classes racing alongside one another, the original SR and for newly manufactured cars and ones that had been converted, SRF with 105 horsepower (10 more than the Renault) and a top speed of 135 mph. Today only the SRF is raced in SCCA.

Nashville Superspeedway – A NEW TRACK! 

  • A new concrete oval, Nashville Superspeedway, is now available! 
  • In 2001, national-level NASCAR racing returned to Nashville when the 1.333-mile Nashville Superspeedway opened and played host to what are now known as the Xfinity and Camping World Truck Series for the first time. Over its first decade, the track became a staple of the schedule for both series, expanding each to two events, while also adding IndyCar racing for the first eight years of its existence. However, without a NASCAR Cup Series date on its calendar, 2011 proved to be the track’s final season, and it would shut down after choosing not to seek NASCAR sanction for 2012. How times have changed. In June 2020, NASCAR awarded Nashville Superspeedway a Cup Series date for 2021, effectively bringing the track back to life. For the first time, it’ll host all three national NASCAR series in June 2021. Like Dover International Speedway, its sister track, Nashville features a concrete racing surface that will present a unique challenge to the many real-world racing stars who will take it on for the first time. You’ll find yourself facing those same obstacles as you attempt to handle the track’s high speeds on iRacing!

Red Bull Ring – A NEW TRACK! 

  • A new asphalt road course, Red Bull Ring, is now available! 
  • The Red Bull Ring is currently pending approval on track signage by the owners of the real world track. It is possible that this process could delay the release of this content. 
  • The Red Bull Ring features three configs; Grand Prix, National, and North. 
  • The Red Bull Ring’s origins date back to 1969, when the Österreichring opened to replace the Zeltweg Airfield as host of the Austrian Grand Prix and attempt to draw the Driver’s World Championship back to the country. That mission was successful just one year later, and the event became a staple of the series until 1987. The track was completely rebuilt in the mid-1990s and rechristened the A1-Ring, which enabled it to return to the circuit from 1997 to 2003. After a period of uncertainty that followed the demolition of the grandstands and pit buildings in 2004, circuit owner Red Bull began its reconstruction of the track in late 2008 and gradually added both modern and vintage events over the years, culminating in the return of the Austrian Grand Prix in 2014. In 2020, with the COVID-19 forcing a rework of the schedule, the Red Bull Ring became the first circuit to ever host back-to-back rounds to open a Formula 1 season, as well as the first European venue to host the opening round of the season since 1966.
