Subaru marks the end of an era after confirming that there would be no more ICE-equipped STI in current or future models.
The Japanese automaker forged its legacy among enthusiasts after Colin McRae popularized the name, winning many WRC races in the 90s. The car in question was based on the 1994 Impreza WRX STI, which quickly grew in popularity thanks to impressive handling characteristics and the soulful boxer engine. The STI version of any Subie is the most powerful and performance-oriented offering in its line-up.
Ever since the early 90s and until 2019, Subaru rolled out the STI a few months after launching its standard versions, aware that enthusiasts and car nuts would obsess over every detail. The last STI sold in North America, the WRX STI S209, produced 341 hp and came exclusively with a 6-speed manual.

Unfortunately, as per the latest press release, the automaker spelled the end for the internal-combustion-engine route without any prior indication. And the reason, just like with many other killed sports cars, is regulations. According to Subaru, the regulations and requirements for greenhouse gasses (GHG), zero-emissions vehicles (ZEV), and Corporate Average Fuel Economy (CAFÉ) necessitate the use of electricity.
Hence, if the Japanese company ever launches an STI again, it would feature at least a hybrid powertrain or even a full-electric one. The company says that it “explores opportunities” for future WRX STI models, so there is at least some hope. Just be prepared to live with the fact that electrons, and not octanes, give you a boost forward.
Interestingly enough, last July, rumors hinted of a powerful 345 hp STI version of the 2022 WRX. As if that didn’t come as a shocker, Subaru just unveiled an S4 STI Performance concept at the beginning of the year, but to no avail.

So, with the OG STI chapter coming to an unusual end (still hurts 🤕), Subaru set its eyes on the ever-growing EV market and a performance-oriented successor, following the footsteps of the Solterra.
Until that happens, it’s time to reflect and celebrate the STI lineage so far!
Sayonara until next time, friend.
