VB · 2021 production start; 2022+ North American model years
A standalone WRX moves to the FA24F turbo while the Impreza follows a separate chassis line.
Production began in 2021 for the 2022 North American model year. The launch-era WRX uses a 2.4-liter FA24F turbocharged boxer four. North American launch output was 271 hp (202 kW; 275 PS) and 258 lb-ft (350 N·m); the Japanese-market WRX S4 was reported at 275 PS and 375 N·m. North American launch transmissions were a six-speed manual or Subaru Performance Transmission; Japanese WRX S4 grades and equipment differ. These are scoped launch records, not a promise that every later year or market kept the same specification.
Standalone WRX line, separate from the contemporary Impreza. The launch evidence summarized here covers North America and Japan; year-by-year changes and other export-market grades remain partial.

Configuration
Model details
The documented North American launch range used Base, Premium, Limited, and GT names; Japan used WRX S4 grades including GT-H and STI Sport R. Trim names and equipment are market-specific. Subaru of America said in March 2022 that no internal-combustion WRX STI would accompany this generation; that statement does not settle any later electrified STI program.

Identification and ownership notes
VB is the standalone WRX chassis line, not the GT/GK or GU Impreza code. A WRX badge, a photograph, or a decoder result alone does not authenticate an individual vehicle, trim, or installed equipment.
