The WRX and WRX STI are seriously outdated. While the new Impreza debuted back in 2016, the current WRX and WRX STI are based on the previous generation.

They’re long overdue for an upgrade and it’s a relief that their replacements are due to arrive in 2021. According to a new report from Forbes, we can expect some pretty big improvements from everyone’s favourite Japanese, rally-inspired saloon. 

Apparently, “sources close to the Japanese automaker” have spilled the beans on a few details surrounding the new WRX. Most importantly, as it relates to horsepower. Obviously, the next generation WRX will be getting a power boost (seriously, what new car doesn’t these days), but that boost may be more significant than we first speculated.

Sources claim the new WRX STI will feature a brand new 2.4-litre turbocharged boxer engine, designated “FA24” and that it will produce no less than 400 horsepower and 361 lb-ft of torque.

That’s a massive leap over the current STI’s 304 hp and 311 lb-ft. But as the familiar 2.0-liter boxer turbo is getting on in years, it’s not surprising that a brand new engine would be so much more potent.  

Apparently, the reworked FA24 will achieve its horsepower increase via a reinforced crankshaft and pistons, optimized timing balance, more boost pressure, and updated valves and intake ports. 

This is a good thing for STI fans. Currently, the car is a bit of a hard-sell at its price point, especially compared to cars like the Honda Civic Type R which offer similar performance and greater creature comforts at a portion of the price. The STI should be the undisputed king of the hot saloon cars and if these rumours end up holding water, it may just be able to reclaim that crown.
