Unveiling the Upcoming Subaru WRX STI

Introduction

While the standard Subaru Impreza has transitioned to the advanced Subaru Global Platform, the performance-oriented WRX and WRX STI models have remained based on the older Impreza architecture. However, recent reports indicate that changes are on the horizon, particularly with the development of a new engine aimed at enhancing performance.

New Engine Developments

According to insiders, the next-generation WRX STI is expected to debut in 2021, showcasing an all-new turbocharged 2.4-liter boxer four-cylinder engine. This upgrade is critical for delivering extraordinary power levels, targeting an impressive 400 horsepower and 361 lb-ft of torque. Currently, the existing WRX STI utilizes the EJ25 turbocharged 2.5-liter engine, producing 310 horsepower and 290 lb-ft of torque.

Performance Specifications

The anticipated STI-spec version of the FA24 engine will likely feature:

• Reinforced crankshaft
• Enhanced pistons
• Increased boost pressure

In comparison, the existing turbocharger configuration in the STI achieves respectable output but limits further performance enhancements due to its aging architecture.

Styling and Design

For the design of the new WRX and STI, fans can expect inspiration drawn from the recent Viziv Performance concepts. However, production models tend to be less aggressive than these initial prototypes.

Conclusion

While specific release dates remain uncertain, reports suggest that the WRX STI will be unveiled before the standard WRX model in 2021. This upgraded approach, along with new powertrains and styling, places the next-generation WRX STI as a highly anticipated vehicle among enthusiasts.
