MPG** UP to (Hwy/Cty)

The most powerful, best-handling, and most exciting Subaru Tecnica International model ever created is here — the 2019 STI S209 represents a level of Subaru performance never before available in the U.S. The limited-edition S209 is designed from the chassis out to balance raw turbocharged power with precise, intuitive handling.


The Most Powerful S-model Ever

Upgraded SUBARU BOXER® Engine

Under the hood, the STI S209 features a SUBARU BOXER engine and a larger turbocharger for increased boost — along with an uprated fuel pump, injectors, and a remapped engine control unit. The result is 341 horsepower and 0 to 60 mph in less than 5 seconds.


"I'm instantly struck by how delightfully direct and communicative the hydraulically assisted steering feels. It's a revelation."

The Best-Handling S-model Ever

Exclusive Dunlop® Summer Performance Tires and 19-inch Forged Wheels

STI engineers worked in conjunction with the tire experts at Dunlop to develop the summer performance tires’ composition and design — all specifically formulated for the needs of the STI S209. They’re mounted on forged 19-by-9-inch wheels — a half-inch wider than standard — designed for lightness as well as strength to deliver quicker suspension response and featuring a 265 mm section width for even more traction. This extreme grip helps the S209 develop over 1.0 g of lateral acceleration on the skid pad.

“As I sizzle my way around its enticing array of tight corners, uphill chicanes, fast sweepers and blind crests, all the S209’s eye-opening numbers seem less surprising.”


Performance Design

Aerodynamic, Lightweight Materials

The STI S209 features performance-first design elements and limited-edition badging throughout the exterior. Flared fenders at all four corners accommodate the widened wheel and tire package. The carbon-fiber rear wing and front underspoiler work together to create more downforce and stability. And the carbon-fiber roof doesn’t just save weight, it also improves body rigidity.

Additionally, several enhancements to the vehicle’s structure allow the suspension to work better.

Have the brakes been upgraded from the standard WRX STI?
