Subaru Tecnica International is the touchstone of all Subaru motorsport and performance vehicles. Since 1988, STI engineers have tuned, tested, and retuned everything from complete vehicles to hand-built engines to race-ready parts. Every STI design comes hard-earned through decades of performance engineering for rally courses, racetracks, and your favorite stretch of curvy road.

2019 S209

The first S-model to be offered in the U.S., the S209 is the most powerful, best-handling, and most exciting vehicle STI has ever created. From the intake through the turbocharged SUBARU BOXER® engine to the drivetrain and down to the exhaust, STI engineers retuned the WRX STI into something new, with 341 horsepower[1] and a 0 to 60 mph time of less than 5 seconds[2]. The suspension, Brembo® brakes, and chassis were upgraded and modified for even better cornering, traction, and response. Every new S-model becomes the new standard for STI engineering, and the S209 is no exception.
