How to estimate it
Fermi’s official “Napkin math”
The Corolla has been around since 1966, so about 60 years by 2026. It's the best-selling car ever made, so how many a year? Call it a million, worldwide.
- Years on sale
- ~60
- Sold per year (avg)
- × 1 million
- 60 × 1M
- ≈ 60 million
Rounded assumptions may give a slightly different estimate. The official answer above is the game’s reference value.
Source calculation & reference
- Best-selling nameplate in history (passed the VW Beetle)
- 1997
- Cumulative sales passed 40 million (Toyota)
- July 2013
- Cumulative sales passed 50 million (Toyota)
- summer 2021
- Cumulative sales passed 57 million (Toyota)
- August 2026
- ≈
- 57 million Corollas
