The same build, other model years
Infiniti used the VIN pattern JN1EV7AP for 5 model years. Nothing but the year changes between these pages, so the price gap between them is depreciation on an identical car.
How this VIN pattern is read
A 17-character VIN carries two kinds of information: what was built, and which one it is. This page is the first kind — the nine highlighted positions.
| Positions | Characters | What they encode |
|---|---|---|
| 1–3 | JN1 | NISSAN MOTOR COMPANY, LTD · World manufacturer identifier |
| 4–8 | EV7AP | Model, body style, engine and restraint system |
| 9 | × | Check digit — computed per vehicle, not part of the build |
| 10 | J | Model year — 2018 |
| 11 | × | Assembly plant |
| 12–17 | ×××××× | Production sequence number, unique to each vehicle |
NHTSA safety ratings
Crash-test results are published per model year and body style, so they cover the 2018 Infiniti Q50 as a whole rather than this build alone.

Vehicles of this build
A fixed sample of 2 vehicles carrying this configuration — each with its own history page. The sample refreshes quarterly, not nightly, so it stays put between visits.
Cars are filed by a fixed rule based on the VIN, so a car never moves between groups.
Neighboring configurations
Other factory configurations of the Q50, each with its own build sheet. The set is fixed by the VIN patterns themselves, so it does not shuffle as prices or inventory move.
