## Tesla specifications at a glance

Current-generation figures for every Tesla we cover. Specifications are set by generation, so older model years may differ; each model page breaks them out generation by generation.

## How we verify Tesla specifications

Every figure on these 2 nameplates is checked against owner's manuals, Tesla service documentation, and NHTSA recall and complaint records, then labelled with how confident we are in it. Where a specification is safety-relevant and we could not confirm it to that standard, the page says so rather than guessing.
