The iRacing 2024 Season 1 Release is here! This release includes both new content and upgrades for 2024 Season 1, which officially starts on December 12th at 0000 UTC! iRacing adds one new car, the Audi R8 LMS EVO II GT3, to our lineup of vehicle content. iRacing also adds one brand new Oval and Road track each to the service: Autodromo Internazionale del Mugello (Grand Prix, and Short), and Slinger Speedway (Oval, and Figure Eight). We also have a complete rebuild of Okayama International Circuit (Full Course, and Short), a fan favorite piece of free Rookie content, using 2023 data.

iRacing 2024 Season 1 includes Phase 1 of the Oval Refresh Project – you will find more realistic track grip levels as they relate to surface temperature throughout the course of a race. With this release, iRacing is pioneering new 3D curb technology at Mugello and Okayama, which should provide drivers with the most realistic track-edge experience to date – every curb bump of any type and size is now fully modeled for tire interaction. Mother Nature has sprouted with the 3D Foliage System at three additional beloved tracks and the system has been further optimized for look and feel.

The New Damage Model comes enabled on the new Audi R8 LMS EVO II GT3, and it has been added to a whopping FIFTEEN more car models, including nearly every Asphalt Oval car we have! Our AI wranglers have approved both the Audi R8 LMS EVO II GT3 and HPD ARX-01c to report for competitive duty, and have unlocked eight new track configs for racing. Our vehicle dynamics team, per usual, have tested every single car, top-to-bottom, and have supplied you with hundreds of fully optimized new vehicle setups. Ring in the new year with iRacing 2024 Season 1!

SIMULATION:

————————————————————–

Optimization

• Improved rendering performance for complex scenes, such as during gridding.

Updater

• Several pieces of Rookie content have been added to our REQUIRED downloads list in preparation for a short new player onboarding experience planned for release within 2024 Season 1. These items include:
• – – Formula Vee
• – – Street Stock
• – – Lime Rock Park
• – – USA International Speedway

Physics

• A new 3D curbs system has been added to a select group of tracks!
• – – The new 3D curb system fully models all curbing at the track, including small curbing previously simulated via a texture. These new fully 3D object curbs allow for a much greater sense of realism for running over curbs and tire interaction. The following tracks now utilize the 3D curbs system:
• – – – – Autodromo Internazionale del Mugello
• – – – – Okayama International Circuit
• In some areas at some tracks, the lateral distance from the track edge for porous surfaces now increases the rolling drag applied by that surface, simulating an increase in depth of the loose off-track surface. Generally, porous material surfaces start out shallow near the track edge and get deeper the farther from the track surface you travel.
• Grass, dirt, sand, and gravel have had improvements to the feeling of surface displacement.
• For grass surfaces, peak shear strength has been reduced slightly when a tire is slipping.

Race Control

• Fixed an issue where your Average Lap Time in a Practice Session was incorrectly including incomplete laps, for example where you reset to your pit stall.

Oval Racing

• iRacing is happy to release Phase 1 for our Asphalt Oval Refresh Project.
• – – Asphalt Oval Refresh is an ongoing project with the aim to improve the overall experience and realism of asphalt oval racing. This release of Phase 1 includes improvements to the surface grip levels as it relates to surface temperature. This should provide a more dynamic experience overall with factors such as weather, car count, and where cars are running on the track.
• ALL Oval track configs (Asphalt, Dirt, large, small, tri-oval, etc.) now calculate drivers’ SR adjustments based on a factor of 4 corners per lap. Previously, many small Ovals were using a value of 2 corners per lap, which would make penalties more punishing for races of similar lengths than those at larger ovals. This change will help equalize the SR playing field between Oval drivers who prefer small or large oval racing.

AI Racing

• AI Racing is now available with the following new cars:
• – – Audi R8 LMS EVO II GT3
• – – HPD ARX-01c
• AI Racing is now available at the following new track configurations:

• NEW TRACK!
• A new asphalt road racing track, Autodromo Internazionale del Mugello, is now available for purchase and racing!
• – – After half a century’s worth of events on public roads were brought to an abrupt halt in 1970, Autodromo Internazionale del Mugello was constructed in 1973 and opened a year later to bring premier racing events back to the area. It quickly became host to major sports car events, lower-level open-wheel series, and grand prix motorcycle racing, for which it has hosted the Italian motorcycle Grand Prix for the past 30 years. In the COVID-19 impacted 2020 World Driver’s Championship, it hosted the series for the first time with the Tuscan Grand Prix. Mugello features two layouts: its 3.259-mile, 15-turn Grand Prix layout, and a 1.4-mile Short configuration. Both start with its lengthy front straightaway and go into the 180-degree San Donato right-hander before heading into Luco and Poggio Secco. The track has been owned by Scuderia Ferrari since 1988, which uses it for both testing and the Ferrari Challenge Finali Mondiali; the Tuscan Grand Prix in 2020 marked its 1000th Grand Prix event.

• – – Known as the “World’s Fastest Quarter Mile Oval,” Slinger, Wisconsin’s Slinger Speedway is the quintessential bullring short track. Opened in 1948, its defining characteristic is its high-banked corners, which reach an imposing 33 degrees on each end. That steep banking allows racers to post blazing fast laps, including Jeff Bloom’s 9.908-second time in 2010-the first quarter-mile oval lap record in history to break the 10-second barrier. Formerly a flat, clay track, Slinger was reconfigured for the 1974 season into its current paved and high-banked state. Its most famous race each year is the Slinger Nationals, a 200-mile Super Late Model race that has been won by some of the biggest names in short track racing and NASCAR alike; former Cup Series champion Matt Kenseth holds the record with eight wins between 1994 and 2019. Slinger also has a paved X running through its center to host Figure 8 events.
