Collection: 15-21 STI
The 2015-2021 Subaru WRX STI stands as a modern embodiment of Subaru’s rally heritage, combining raw power with precise handling to create a driving experience that thrills both enthusiasts and purists. Powered by the iconic 2.5L turbocharged boxer engine, this generation STI delivers 310 horsepower (updated for 2018) through its symmetrical all-wheel drive system, giving it incredible traction and acceleration across all road surfaces. With a stiffened chassis, advanced driver-controlled center differential (DCCD), and rally-bred suspension, the STI is engineered to carve through corners with precision while maintaining Subaru’s legendary confidence-inspiring grip.
In 2018, Subaru introduced several key updates to refine the STI even further. The addition of stronger Brembo brakes with six-piston front calipers and cross-drilled rotors provides even greater stopping power and fade resistance. Subaru also recalibrated the DCCD for smoother handling dynamics and more balanced power distribution. A refined interior, featuring updated materials and an upgraded infotainment system, made the 2018 STI more tech-forward and driver-focused. These changes elevate the already-capable 2015-2017 STI, making the 2018+ model years an even sharper, more engaging performance car both on and off the track. Whether tackling winding roads or dominating at autocross, the 2015-2021 STI continues to deliver the kind of visceral, turbocharged thrill that Subaru fans crave.
