We’ve been posting on social media recently about the new WRX STI as well as Subaru’s participation in the Isle of Man TT, one of the toughest races in the world, and where the Subaru World Rally Team continues to dominate. Have you ever wondered what STI means though?

STI stands for Subaru Tecnica International, the performance division of Subaru. This division was formed to manage Subaru’s growing motorsports activities in the early 1990s and has since grown to enhance the driving experience for Subaru drivers on the road. Starting with the 1991 Legacy STI (available overseas), the division has been using their motorsports experience to design and manufacture STI versions of vehicles as well as parts and accessories for Subaru vehicles. STI is made up of engineers who dedicate themselves to discovering how they can improve not only the power and performance of their vehicles but also how to make them more enjoyable to drive. They use input from racers as well as simulators wind tunnels and tracks in all types of weather conditions to test and refine the design of vehicles to make them “more communicative, responsive, and easier to push faster, harder, and closer to the limit” in order to “create the ultimate driving experience.” (http://www.sti.jp/)

Of course, not every Subaru gets an STI edition; in fact, North America did not get to experience what STi is all about until the 2004 Impreza WRX StI. However, STi knowledge and experience does go into the design and manufacture of all Subaru models. For this year, you can find STi technology in the 2015 WRX STI.
