The reference database for
cars, engines and machinery.

PromtEngine is building a structured technical database covering vehicles, engines and machinery — specifications, engine families, applications, emissions and measured performance, drawn from government and open data rather than guesswork. Alongside it sits a library of practical troubleshooting and maintenance reference.

What we are building

Most vehicle specification sites carry a single market, a single source, and no way of telling you where a number came from. PromtEngine is being built the other way round: every specification is traceable to the dataset it came from, cross-checked against other sources where they overlap, and connected to the engine family, applications and related machinery around it.

That covers passenger cars and light trucks, but also the areas that are badly served elsewhere — industrial and non-road engines, tractors and agricultural equipment, construction machinery, marine and powersports engines, and the engine families that appear across all of them.

Development services

The same engineering that runs this platform is available as a service. We build vehicle and machinery data platforms: ingestion pipelines from public and commercial sources, entity resolution across catalogues, specification databases, and the search and comparison layers on top.
