TL;DR
Ryan Montgomery created Roadster Atlas, a free interactive 3D model of the 1999–2005 NB Mazda MX-5 Miata, using his 2004 Mazdaspeed Miata as a starting point. The model includes 699 individual parts, exploded views and animations; Montgomery says he plans to model other Miata generations next.
Ryan Montgomery has created Roadster Atlas, a free interactive 3D model that lets users inspect and disassemble a digital 1999–2005 NB Mazda MX-5 Miata. Built from his own 2004 Mazdaspeed Miata and containing 699 individual parts, the browser-based project offers owners and enthusiasts a way to see how components fit and move without taking a physical car apart.

The model covers parts ranging from body panels to bolts, and the engine can be separated into individual components. Users can rotate the car with a click-and-drag control, view it with the body removed or inspect an exploded view that spreads components apart. The report by The Drive says the project is accessible through a browser, without an account or download, and can be viewed on mobile devices. Montgomery has advised that a desktop browser is preferable.
Roadster Atlas also includes animated demonstrations. Users can watch the engine rotate and see how different suspension settings change the geometry. Those features make the model more than a static parts diagram: it offers a visual way to explore how the car is assembled and how selected mechanical systems behave.
The Drive reports that Montgomery based measurements on Mazda’s published specifications, alongside information from media and community sources. That material included input from owners whose cars had been disassembled. The project uses Montgomery’s Mazdaspeed as its starting point but is intended to represent the broader NB generation, rather than only that specific car.
A Visual Guide to Miata Components
For owners planning modifications or trying to understand a particular system, a model that shows how components relate can provide useful orientation before they consult detailed repair information. The ability to remove digital bodywork, separate parts and watch selected mechanisms move may help users form a clearer picture of the car’s layout than a conventional exterior rendering would.
That usefulness has limits. Roadster Atlas is not a substitute for a shop manual, according to the report, and its visual explanations should not be treated as repair procedures or a source of verified instructions for a specific vehicle. Still, making a detailed model freely available in a browser lowers the barrier to exploring the NB Miata’s construction, including for people who do not own one or have access to a disassembled car.

Built Around the NB Miata
The NB was the second generation of Mazda’s MX-5 Miata and covered model years 1999 through 2005. Montgomery used his 2004 Mazdaspeed Miata as the project’s starting point, then drew on published specifications and other sources to make the model representative of the generation. The project is associated with Roadster Republic, Montgomery’s Miata-themed lifestyle brand, according to The Drive.
Roadster Atlas brings together details that are often encountered separately: parts diagrams, exterior views and demonstrations of mechanical movement. Its exploded views let users examine how pieces are arranged, while interactive controls allow inspection from different angles. The Drive reported that Montgomery spent months making the model, though the available source does not give a precise start date or a more detailed production timeline.
“The model is best viewed on a desktop.”

Limits of the Digital Model
The available reporting does not specify how each of the 699 parts was verified, whether every NB model-year or trim variation is represented, or how closely the digital model matches differences among individual cars. Montgomery’s use of Mazda specifications and community information is described, but the source does not provide a part-by-part methodology or accuracy assessment.
It is also unclear whether Roadster Atlas includes repair instructions, torque values or other specifications needed to carry out work safely; the report says it is not meant to replace a shop manual. Users should treat it as a visualization tool and consult appropriate service information for maintenance or repair. The source does not give a dated schedule for additional generations.
More Miata Generations Planned
Montgomery says other Miata generations are planned for future versions of Roadster Atlas. No release dates or specific generations were provided in the source report. For now, the NB model is available to explore for free in a browser, with the desktop experience recommended for inspecting its parts and animations.
Further updates could show how the project handles differences among generations and variants, but those details have not been announced in the available reporting. Until additional models are released, the NB remains the project’s focus.
Key Questions
What is Roadster Atlas?
It is a free interactive 3D model of the NB-generation Mazda MX-5 Miata, with controls for rotating the car, removing bodywork and separating components.
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 broken down into its components.
Does it work on a phone?
The model can be viewed in a mobile browser, but Montgomery recommends a desktop browser for the interactive experience.
Can it replace a Miata repair manual?
No. The report describes Roadster Atlas as a way to visualize how parts fit and move, not as a replacement for a shop manual or a complete repair guide.
Will other Miata generations be modeled?
Montgomery says other generations are planned, but no release dates or specific models were provided in the source report.
