Collection: 18-21 STI
The 2018-2021 Subaru WRX STI represents the pinnacle of Subaru’s performance lineup, combining raw power with advanced technology and a commitment to driving excitement. Powered by a 2.5-liter turbocharged boxer engine producing 310 horsepower, the STI delivers exhilarating acceleration and unmatched grip, thanks to its legendary symmetrical all-wheel drive and driver-controlled center differential (DCCD). The aggressive styling, with its bold front fascia, muscular stance, and iconic rear wing, commands attention on and off the track.
During this generation, Subaru introduced the limited-edition Type RA and the ultra-exclusive S209, both of which pushed the boundaries of performance even further. The Type RA offered enhanced aerodynamics, reduced weight, and improved handling, making it a more agile and track-focused version of the STI. Meanwhile, the S209 raised the bar with its bespoke tuning, lightweight components, and a powerful 341-horsepower engine, delivering an exhilarating driving experience that few can rival.
