RENNSPORT | RENNSPORT's first update of 2026 includes the “Endurance Classics” DLC and improves the AI

After months of uncertainty and multiple delays, RENNSPORT's first update of 2026 has now been released. It is available for PC and consoles starting today and, alongside new paid and free content, includes numerous optimizations for the racing simulator, which has so far been plagued by technical difficulties.

The update focuses on the release of the “Endurance Classics Part 1” DLC. The first paid DLC is available for €12.79 on Steam and €11.99 on PS5 and Xbox. It expands the vehicle selection with several historic Group C prototypes and GT1 cars, including the 1998 Le Mans winner, the Porsche 911 GT1, the Mercedes-Benz CLK LM, the Porsche 956, and the Peugeot 9X8 Evo.

These vehicles can be driven on a laser-scanned version of the Circuit des 24 Heures du Mans, which is also included in the DLC.

In addition to the paid DLC, the update includes extensive free content, including the Kuala Lumpur Street Circuit, additional track layouts for Fuji and Monza, the Road Atlanta Short Circuit, the Nürburgring Fast Chicane, the Daytona Tri-Oval, the 8ETA Oval, and the Hyundai N Vision 74.

The update also introduces the first stage of RENNSPORT's overhauled AI architecture. Until now, the unpredictable behavior of AI opponents had been one of the game's most noticeable weaknesses. According to the developer, the AI has been “fundamentally overhauled,” meaning opponents now “understand space, aggression, and the physical consequences of a collision.”

“The last time we released an AI, it probably should never have been released in that form,” explained lead gameplay programmer Rikard Häggström.

“It had to be implemented in a relatively short period of time. I would say it was largely a prototype. With an approach like that, it is easy to end up in a situation where you make decisions along the way that are not optimal in terms of sustainability. We have now reached the point where we need to reprogram the game so that it works properly in the long term.”

The single-player experience is further enhanced by an overhauled Championship mode. Instead of being divided into Beginner and Pro tiers, events are now grouped into playlists. A new points system provides a more transparent sense of progress, and rankings can be compared in new global leaderboards.

In multiplayer, the new “Custom Contests” mode allows players to create individual online events. Track limits have also been adjusted. New lens-flare effects and increased graphical contrast additionally provide a more “cinematic” presentation.

To attract new players, the Deluxe Edition is currently available at a 45% discount; shortly afterward, the Standard Edition will be reduced by 50%.

RENNSPORT's first major update of 2026 arrives after a turbulent period for the racing simulation. It was originally scheduled for release in March but was delayed by several months after developer Competition Company separated from Nacon in order to distribute the game independently in the future.

Competition Company aims to double the amount of content in RENNSPORT. Further free updates and additional DLCs are therefore expected over the course of the year.

Under the Hood: Fixes & Stability

We have squashed hundreds of bugs to make your experience smoother. Here are the highlights:

• Stability: Fixed various crashes to keep you on the track and out of the menus.
• Gameplay: Added Tire Wear Equalization to reduce the long-term impact of flat spots. We also fixed a "lag" issue where crossing the finish line sometimes wouldn't count your lap.
• User Interface: A massive cleanup of the menus! Icons are now sharper, navigation is more intuitive on controllers, and the MFD (Multi-Function Display) is clearer during races.
• Hardware: Improved support for Logitech and Revosim hardware, and added deeper vibration functions for a more tactile driving feel.
• Audio & Lighting: Fixed "ghost" car sounds in qualifying and corrected lighting issues on Daytona and the Nürburgring.

08 // Technical Changelog

Stability & Performance

• Client Architecture: Resolved several critical exceptions causing unexpected desktop crashes during active racing sessions.
• Initialisation: Addressed a fatal initialization error where the software would hang or crash if a user prematurely terminated the First Time User Experience (FTUE) setup.

Gameplay & Physics

• Tire Dynamics: Implemented a refined tire wear equalisation algorithm to simulate the gradual smoothing of flat spots over time, reducing physical vibration and restoring predictable grip levels as a stint progresses.
• Transition Logic: Eliminated an erroneous penalty trigger that occurred during the immediate transition between race stages.
• Network Synchronisation: Corrected a race-logic bug where high-latency connection spikes across the start/finish line resulted in unregistered laps.
• Vehicle Physics: Rectified an issue where incorrect ride height parameters were applied to vehicles within the showroom and garage environments.
• Session Persistence: Addressed a tracking bug where event standings and multiplayer leaderboards failed to update reliably post-session.

AI Systems

• Pathing & Navigation: Corrected a behavioral flaw where AI drivers would cut or skip multiple corners in the absence of defensive pressure or external circuit interference.
• Behavioral Overhaul: Executed a comprehensive architectural rewrite to improve competitive positioning, defensive lines, and overall spatial awareness across all grid sizes.

User Interface (UI)

• Data Integrity: Restored missing RENNSPORT Ratings within official contest lobbies and ensured Safety Ratings are fully visible on player cards and user widgets.
• Navigation Logic:
  • Resolved a soft-lock occurring when navigating to session information within the Quick Play interface.
  • Fixed directional input failures on the pit screen that prevented returning to the "Go on Track" state after accessing the drivers table.
  • Corrected a menu restriction in the First Time User Experience (FTUE) setup that blocked users from reaching the "Complete Setup" option without using shoulder buttons (LB/RB).
  • Resolved an issue where menu navigation focus would unexpectedly shift or disappear entirely while interacting with the Replay user interface.
  • Fixed directional input failures when attempting to navigate the leaderboard after applying custom filters on the stage results screen.
