If you’ve been following the development of the dirt racing simulator community, you may have noticed a new name gaining attention: DirtSim. But where did it come from, and how did it evolve from what was previously known as Dirt Track Racing 2.5?
The history is still somewhat incomplete, but there are enough breadcrumbs to put together a reasonable timeline of the project’s development and its transition into the DirtSim platform.
It Started With Dirt Track Racing 2
For longtime dirt racing simulation enthusiasts, the story begins with Ratbag’s original Dirt Track Racing 2. Although the original game is getting long in the tooth, its community has kept it alive through years of modifications, custom tracks, cars, chassis, paint schemes, and online racing.
Team VLR became one of the names associated with keeping that community active, continuing to develop and support the game long after its original commercial life had ended.
September 2026: Dirt Track Racing 2.5 Beta
One of the first concrete milestones in the newer project’s development appears on September 27, 2026, when Team VLR published a download titled DTR2.5 Beta Game!
The beta release was particularly interesting because its description specifically mentioned testing track wear and improved visuals. These features suggested that development was moving beyond simply maintaining the original game.
The beta was subsequently updated on October 5, 2026. The available download was identified as:
DTR2.5-BETA-195-Full-Setup.exe
This gives us a documented starting point for the DTR2.5 beta phase, although development may have begun considerably earlier.
October 2026: The Emergence of DirtSim
By October, the project was appearing under a new identity: DirtSim.
One documented milestone came on October 25, 2026, when the DirtSim news archive announced the arrival of ranked racing.
This was an important development. DirtSim was no longer being presented simply as a modified version of an older racing game. It was developing its own online racing infrastructure and competitive environment.
The platform’s features include:
- Online organized racing
- Driver ratings and racecraft scoring
- Ranked competition
- Track surface evolution and wear
- Race replays
- Photo mode
- An expanding track library
- Support for grids of up to 64 drivers
These features point toward a more comprehensive dirt racing simulation experience.
A Different Direction: The Move to Unreal Engine
I had the opportunity to speak directly with DirtSim developer Howard Weaver, who clarified an important distinction in the project’s history.
According to Weaver, Dirt Track Racing 2.5 was a modified version of the original Dirt Track Racing 2. DirtSim, however, is an entirely different undertaking. The development team began experimenting with Unreal Engine, eventually building DirtSim as a separate, independent racing simulation. It is not a continuation, modification, or reworking of either DTR2 or DTR2.5.
There is, of course, a strong historical connection. Howard Weaver’s roots, along with those of Team VLR, are closely tied to the original Dirt Track Racing 2 community. That history helped establish the foundation of experience and enthusiasm behind the project. But the technology, development direction, and resulting game are something entirely new.
In other words, DirtSim may have roots in the DTR2 community, but it isn’t DTR2.5 with a fresh coat of paint. It’s a new simulation built on a different engine, with its own development path and ambitions.
Team VLR continues to list DTR2.5 as a separate download within its traditional Dirt Track Racing 2 downloads section. Meanwhile, DirtSim has its own website, branding, and racing infrastructure.

This serves as a no-nonsense entry into realistic driving. Dual-motor force feedback delivers honest steering weight and road detail, while the sturdy floor pedals offer progressive braking and smooth throttle. Stainless steel paddle shifters, a leather-wrapped rim, and a full 900-degree rotation create a setup that earns its spot on your rig without needless extras. It works cleanly with Xbox Series X|S, Xbox One, and PC.

Where Things Stand Today
DirtSim represents an interesting development for the dirt racing simulation community. Rather than simply preserving an older title, the project appears to be building a more complete racing environment around the familiar dirt racing experience.
For those who have spent years racing dirt online, the prospect of a dedicated platform with organized competition, evolving track surfaces, driver ratings, and larger fields is certainly worth watching.
I haven’t been active in the community for quite some time, but I’m looking forward to giving DirtSim a try. Sometimes the best reason to fire up a racing simulator is the simplest one: load the game, join a race, and go have some fun.
And that’s something the original Dirt Track Racing 2 understood remarkably well.
Historical note: The dates above reflect the publicly documented release and news entries located during research. The exact transition date from DTR2.5 to DIRTSIM has not yet been independently verified.
