More Next-Generation 2021 Subaru WRX STI Details Surface
Recent reports out of Japan’s BestCarWeb site gives new details on the next-generation 2021 Subaru WRX STI. This information has not been confirmed by Subaru Corp, so it’s still rumored at this time. We do know the next-generation WRX/STI is coming sometime next year getting major upgrades and the Subaru Global Platform.
BestCarWeb is reporting the new 2021 STI will be exchanging the EJ25 2.5-liter turbo Boxer for the new FA20 Direct Injection Turbo Boxer that currently powers the sport-tuned WRX sedan. The website says power will be increased to 315 horsepower, a bump of 5-hp from the current 2.5-liter turbo engine, and would produce around 325 lb-ft of torque.

They say WRX and Levorg, at least in Japan, will be getting a newly developed 1.8-liter and 1.5-liter downsized direct-injection turbo Boxer. The 1.8-liter would produce 266 horsepower matching the WRX 2.0-liter output and the 1.5-liter will pump out 148 horsepower.
The report goes on to say, the STI will not be getting an automatic transmission option and will still be one of the few remaining vehicles to only be offered with a manual gearbox. The WRX will stay with the 6-speed manual and also the Lineartronic CVT automatic fitted with EyeSight driver assist.
Earlier reports from Road & Track say the new 2021 Subaru WRX STI will be powered by the Ascent, Legacy and new Outback-sourced 277 horsepower FA24 2.4-liter turbo Boxer. Subaru Tecnica International would rework the internals and bump up horsepower and torque considerably if they use it in the next-generation WRX STI.
It’s reported the 2.4-liter turbo could make 330 plus horsepower in the new STI which would make performance fans happier than the upgraded 2.0-liter’s 315 horsepower. Subaru could also use the 2.4-liter turbo mated with new hybrid technology being developed now.
VIZIV Performance Concept
We are expecting the next-generation 2021 Subaru WRX in Concept form to break cover at the Tokyo Motor Show in October that will give fans a better idea of what the exterior styling will look like.
Of course, this is all speculation and has not been confirmed by Subaru Corp who has been quiet about the new performance sedan overhaul. Subaru needs to replace the aging 2.5-liter EJ25 Boxer in the fourth-generation 2020 Subaru WRX STI and a new turbocharged engine will likely get the nod. Stay tuned.
