New Subaru WRX STI To Get 400 HP From 2.4-Liter Turbo Boxer?


The next-gen Subaru WRX STI will allegedly pack a version of the brand’s 2.4-liter turbocharged boxer four-cylinder making 400 horsepower (298 kilowatts) and 361 pound-feet (490 Newton-meters) of torque, according to “sources close to the Japanese automaker” speaking to Forbes. The new model reportedly arrives in 2021.

A version of this engine is already available in the Subaru Ascent and turbocharged variants of the Outback and Legacy where the mill offers 260 hp (194 kW) and 277 lb-ft (376 Nm) of torque. This insider indicates that the version for the STI would gain stronger internal components, revised valves, and more boost to allow for the significant increase in power. There are no transmission details, but like every WRX STI, it would hook up to an all-wheel-drive system.

Styling for the new STI reportedly takes cues from 2017’s Subaru Viziv Performance Concept (picture above). Its styling is reminiscent of the current model but with much sharper lines and a more coupe-like silhouette.
