Subaru is currently working on its next-generation of the subaru WRX STI engines and there’s a very real possibility that these will be the Japanese automaker’s last series of internal combustion engines.
It is understood that the flagship WRX STI will feature a 2.4-liter turbocharged boxer engine with no less than 400 HP. That is a significant jump up from the 310 HP and 290 lb-ft (393 Nm) of torque of the current car. Interestingly, it is claimed that Subaru isn’t just moving to an enlarged 2.4-liter engine for more power but also because the 2.4-liter is said to be more efficient and has better driveability.
Meanwhile, the lesser Subaru WRX is also expected to use a version of the same 2.4-liter turbocharged four-cylinder. It will be detuned but should offer up more than the 268 HP and 258 lb-ft (349 Nm) of the current WRX. It will be available with a six-speed manual and an upgraded CVT. Horsepower and torque figures aren’t mentioned although Car Sensor does claim the car’s CVT can’t handle more than 295 lb-ft (400 Nm).
Both the new WRX and WRX STI will sit on the Subaru Global Platform and feature the brand’s symmetrical all-wheel-drive system.
The report asserts the new models will launch in early 2022.
