The 2021 Subaru WRX STI won’t get the IIHS highest safety score because it doesn’t come with EyeSight driver assist technology. The STI is now the only model in Subaru’s lineup without EyeSight. The 2022 Subaru BRZ now comes with EyeSight leaving the STI standing alone. The reason why the STI doesn’t have it and won’t get it anytime soon is Subaru Corporation doesn’t want to spend their research money on figuring out a way to make it work with a standard gearbox. Thankfully, the 2021 WRX STI only comes with a 6-speed manual transmission for performance enthusiasts.
