Why it matters
The S401 was the first S-series STI complete car based on the Legacy rather than the Impreza, a refined high-performance saloon companion to the S202. It was announced as a 400-car run, and reports suggest fewer were completed.

02Production & history
Production
Every figure says what it counts.
| What is counted | Figure | Basis | Status |
|---|---|---|---|
| Factory package productionLimited edition – the stated limit of the run: announced limited run (限定400台); PistonHeads believes only 286 were built | 4001 | Factory production | Independently researched |
Independent counts (e.g. engine and colour) are never combined into a calculated figure. Surviving examples are never presented as original production.
History
Launched in 2002 on the Legacy B4 RSK, the S401 had its EJ20 twin-turbo engine hand-balanced (pistons, connecting rods, crankshaft) with new induction and exhaust, giving 293 PS. STI added stiffer springs, new anti-roll bars, strengthened engine, gearbox and bush mounts and a quicker steering ratio. It sold for 4,350,000 yen.
Production was capped at 400, but PistonHeads reports that about 286 may have been built before the model ended.
