Ryan Montgomery, founder of Miata-themed brand Roadster Republic, has created Roadster Atlas, a free interactive 3D model based on a 2004 Mazdaspeed Miata. The model includes 699 individual parts, exploded views and demonstrations of engine movement and suspension geometry; Montgomery says other Miata generations are planned.
Ryan Montgomery, the person behind Miata-themed lifestyle brand Roadster Republic, has made Roadster Atlas, a free interactive 3D model that lets users inspect and disassemble a digital representation of the 1999–2005 Mazda MX-5 Miata. Based on Montgomery’s own 2004 Mazdaspeed Miata, the browser-viewable project contains 699 individual parts and is intended to help enthusiasts see how the car’s components fit together.
As reported by The Drive, Roadster Atlas covers components ranging from body panels to bolts, and allows users to view the car in body-off and exploded configurations. Users can click and drag to change the viewing angle. The model also breaks the engine down into individual components, making it possible to explore how assemblies are arranged rather than seeing only the complete car.
The interactive features go beyond static part views. The engine can be shown rotating, and users can see how different suspension settings alter geometry. The model is accessible through a browser without an account or a download. It can be viewed on mobile browsers, though Montgomery said in a Reddit post that a desktop is the better way to use it.
Montgomery used his 2004 Mazdaspeed Miata as the starting point, but the project is meant to represent the broader NB generation, which ran from model years 1999 to 2005. The Drive reports that the measurements draw on Mazda’s published specifications and information from media and community sources, including owners who have disassembled their cars.
A Visual Guide to Miata Components
Roadster Atlas gives owners and enthusiasts a way to explore a car’s layout without taking apart a physical vehicle. Its exploded views and moving components may help users understand how parts relate to one another, including before considering an upgrade. The model may also make unfamiliar mechanical systems easier to picture for people learning about cars.
That usefulness has limits. The source describes the project as a visual aid, not a replacement for a shop manual or repair instructions. A 3D view can show arrangement and movement, but it does not by itself establish the correct procedure, tools, safety precautions or specifications for a repair. Owners working on a vehicle still need reliable service information appropriate to its exact model and configuration.
The project is also notable as a free, browser-based resource for a specific generation of a widely known sports car. Rather than requiring specialized software or an account, it lets visitors explore the model directly online. Its level of detail could make it useful to curious fans as well as owners, while the planned expansion to other generations could broaden its audience if those models are completed.

From a 2004 Mazdaspeed Miata
The NB Miata is the second generation of Mazda’s MX-5, covering model years 1999 through 2005. Montgomery based Roadster Atlas on his own 2004 Mazdaspeed Miata, but says the model is intended to represent the generation as a whole rather than that one car alone.
According to the source report, the model’s measurements combine Mazda’s published specifications with media and community material, including input from owners whose cars had been taken apart. The source does not provide a full technical validation process or describe how differences between NB variants are represented. That distinction matters for anyone using a general-generation model to understand a specific car.
“The model is best viewed on a desktop.”
— Ryan Montgomery, in a Reddit post, as quoted in The Drive’s report
Questions About Coverage and Accuracy
The source material does not say whether Roadster Atlas has been independently checked against Mazda service documentation or how closely it captures differences across NB trims and model years. Although the reported measurements draw on published specifications and other sources, the model’s validation process is not detailed. Users should not assume every component or measurement applies exactly to every NB Miata.
The report also does not specify when additional generations will appear, which models Montgomery plans to produce first, or whether future versions will include the same level of detail. It describes Roadster Atlas as free to view, but gives no information about licensing, reuse or whether the project will remain available indefinitely.
Other Miata Generations Planned
Montgomery says other Miata generations will be rendered next, according to The Drive. The report does not give a release schedule or name the next model, so the timing and scope of future additions remain unknown. For now, readers can explore the NB-generation model through a browser, with a desktop recommended for its interactive views.
Key Questions
What is Roadster Atlas?
It is a free interactive 3D model of the NB-generation Mazda MX-5 Miata. Users can inspect the car, view exploded configurations and explore individual components in a browser.
Which Miata does the model represent?
Montgomery based it on his 2004 Mazdaspeed Miata, but the project is intended to represent the NB generation, which covers model years 1999 to 2005.
How many parts are included?
The Drive reports that the model contains 699 individual parts, from body panels to bolts. The engine can also be viewed as separate components.
Can Roadster Atlas be used to repair a Miata?
It can help users visualize how parts fit together, but the source says it is not a replacement for a shop manual. The model does not provide a substitute for vehicle-specific repair procedures or safety guidance.
Will other Miata generations be added?
Montgomery says other generations are planned. The report does not identify which generation will come next or provide a release date.
