Subaru of America marked the 30th anniversary of the founding of Subaru Tecnica International (STI), the championship-winning motorsports subsidiary of parent company Subaru Corporation and developer of high-performance Subaru vehicles and parts. 

STI’s competition-proven engineering has been a critical influence on Subaru new-vehicle development, specifically the brand’s focus on driving performance that instills driver confidence. The WRX STI was the first STI model offered in the U.S. market (2004) and remains the Subaru’s performance flagship.

Since its inception on April 2, 1988, STI has taken Subaru to three World Rally Championships, 47 WRC overall wins, and four class wins in Germany’s 24-Hours Nürburgring. Rallying success continues, and STI will again return to the Nürburgring 24-Hour race in May.

In July 2017, Subaru made history at the Nürburgring Nordschleife (north loop), setting the lap record for sedans at a stunning 6:57.5 with a WRX STI Type RA NBR with the help of Subaru of America and Prodrive. This car also set lap records at the Isle of Man TT and the Goodwood Festival of Speed hill climb, where it was third fastest. Subaru celebrated the car’s records by issuing the limited-production 2018 WRX STI Type RA (Record Attempt), with 500 units allocated for the U.S. The 2018 WRX STI is the best-handling, best-performing STI yet, and the WRX STI Type RA ups the ante with more power, a carbon fiber roof, Bilstein® STI Sport Suspension and a modified Multi-Mode Vehicle Dynamics Control (VDC) system. Also for 2018, Subaru is offering a limited-run BRZ tS (tuned by STI) featuring STI aerodynamic body design, STI-tuned suspension and 18-inch wheels.
