Subaru WRX vs Subaru STi
Note: this comparison is for WRX and STi models from 2015 through 2021. Subaru introduced an all-new 2022 WRX and announced that there would not be a 2022 STi. It could be a while before we see a new STi since Subaru is exploring electrified powertrains, and presumably one of those would take a few years to develop. Until then, we will continue to stock used STi models.
Planet's Executive summary:
With 578 horsepower between the two of them, you can't go wrong. For under $30,000, you can drive the Subaru WRX, a turbocharged, all-wheel-drive performance car, respected the world over. If you have approximately $10,000 more, you can buy the STi--a WRX on steroids. For the extra money, you get a bigger engine with more power, an even more sophisticated suspension, and many other upgrades.
