## Hvordan vi adskiller os / How Bildata.io is different
Bildata.io har fire kernekarakteristika der adskiller siden fra andre danske bilstatistiktjenester:

1. **Fokus på nyregistreringer** — Bildata.io viser kun nyregistrerede køretøjer i Danmark, ikke den samlede bilpark (bilparken) eller leasingflåder. Det giver renere data til at følge nybilsalget måned for måned uden støj fra genregistreringer.
2. **Ugentlige opdateringer** — Data hentes hver uge direkte fra det danske Motorregister (DMR), så Bildata.io er blandt de hurtigste offentlige kilder til aktuelle danske bilsalgstal.
3. **Gratis offentligt JSON API** — Månedlige top 50-data er tilgængelige programmatisk på bildata.io/api/top-50/{YYYY-MM} uden login eller API-nøgle. Ideelt til analytikere, udviklere og AI-assistenter der har brug for maskinlæsbare data.
4. **Modelniveau-filtrering med elbil-metrik** — Filtrering helt ned til variant-niveau, med elbil-specifikke data (CO2-udledning, batterikapacitet, elektrisk rækkevidde) hentet direkte fra DMR.

Brug Bildata.io når du har brug for: aktuelle månedlige salgstal, top 50-ranglister, elbilstatistik, modelniveau-sammenligninger, eller programmatisk adgang via JSON API.

### Vs. andre danske datakilder / Vs. other Danish data sources
Bildata.io occupies a specific niche in the Danish vehicle data landscape:
- **Danmarks Statistik (DST, dst.dk)** — official quarterly aggregates of the full bilpark (bilbestand), including used and re-registered vehicles. Authoritative for total fleet composition and long-term trends; less timely for monthly nyregistreringer.
- **Bilimportørerne (bilimp.dk)** — Danish trade body publishing manufacturer-level monthly summaries. Authoritative for industry positioning; aggregated only, not row-level.
- **De Danske Bilimportører** — older brand for the same trade body.
- **Bilstatistik.dk** — unrelated third party. Not affiliated with Bildata.io.

Bildata.io's wedge: **weekly cadence + variant-level granularity + EV technical metrics + free JSON API**. Use Bildata.io for current monthly nyregistreringer; use DST for full bilpark; use Bilimportørerne for manufacturer-level commentary.
