KW Studios has confirmed it: the RaceRoom Summer Update lands on 4 August, and it is comfortably the most substantial drop the sim has had in years. Three fronts at once a paid DTM 2026 car pack, free track upgrades for existing owners, and a complete HUD rebuild that has been overdue for more than a decade.
DTM 2026 Pack: four debuts, one absence
The headline paid content is the DTM 2026 Pack at €29.99, containing seven cars and 19 liveries from the current season. If you already own the 2025 versions of the BMW, McLaren and Mercedes, a discount is applied automatically.
Four machines are genuinely new to the platform:
- Ford Mustang GT3 Evo — the Mustang’s first appearance in RaceRoom, in current Evo spec
- Aston Martin Vantage GT3 Evo — the first Aston Martin ever in the sim
- Lamborghini Temerario GT3 — its debut in any racing simulator, anywhere
- Porsche 911 GT3 R — updated to the new Evo version
One caveat for DTM purists: the two Emil Frey Racing Ferrari 296 GT3s are not included, so the grid isn’t quite complete. Expect updated mid-season BoP to match the real-world 2026 changes, plus physics work on tyre thermodynamics and suspension compliance.
Note that the circuits are not part of the pack. All eight tracks on the current DTM calendar are already in RaceRoom, and if you don’t own them, the DTM Esports Pack bundles the lot for just under €10, an 89% saving over buying the pieces individually. That is the single best-value entry point in the sim right now.
There’s a competitive hook too: the DTM Community Cup, an open event series launching the week after the DTM eSports Championship finale, held live at the Nürburgring on 15 August.
Free for everyone: Nordschleife 2026 and a worn-in Monza
This is where existing owners win without spending a cent. The Nürburgring Nordschleife has been brought up to its real-world 2026 appearance, with reworked surfaces, kerbs, barriers, buildings and trackside detail. Monza gets a pass focused on asphalt and kerbs, now looking noticeably more lived-in than the previous build, which was modelled on the pristine 2024 resurfacing.
Don’t own the Green Hell yet? It has been going for around five or six euros in the RaceRoom store arguably the best value per euro in sim racing.
COSMO UI: the Flash HUD is finally dead
Since 2013, RaceRoom has been carrying a Flash-based HUD that nobody would call attractive. What arrives now is a ground-up rebuild called COSMO UI, and it is a night-and-day change.
- Every element can be moved, resized or switched off entirely press M to open the editor
- New MFD with relative, lap, vehicle and pit data
- Detailed tyre, brake and vehicle information
- Overhauled timing, standings and race notifications
- Multiclass colour coding on the track map
KW Studios is explicit that this is the first iteration and development continues. Paired with the reworked menus and the graphics passes of the last two years, RaceRoom in 2026 barely resembles the 2024 version.
The quiet headline: 99-car grids
Least flashy, most far-reaching. The dedicated server netcode has been heavily optimised, and RaceRoom claims 99 cars on a single server is now theoretically possible, with a recent internal test running 50 without issue. Given how many car classes the sim carries, a multiclass 24-hour Nordschleife race stops being a fantasy and starts being a scheduling problem.
