It is reported that next-generation Subaru WRX STI is on line and it could have a horsepower of 90 (67 kW / 91 PS) and 71 lb-ft (96 Nm) more than its predecessor. Forbes reported that the next-generation WRX STI will arrive in 2021 and said that the model with feature a turbocharged 2.4-liter boxer engine which will produce “no less than” 400 horsepower (298 kW / 406 PS) and 361 lb-ft (489 Nm) of torque.
Reports suggest that the engine will be based on the turbocharged 2.4 liters four-cylinder that resides in Ascent. Nevertheless, it will eventually come with a host of changes as per rumors. Some of the rumors in terms of the feature of the upcoming next generation Subaru WRX STI are the incorporation of new pistons, a reinforced crankshaft, and upgraded valves and ports. Forbes also said that the “boost pressure will be tweaked” which suggests a revised turbocharged.
As of now, nothing has been confirmed by the company yet. So far it is only revealed that the engineers have benchmarked the engine against the turbocharged 2.0-liter four-cylinder that was created by Mercedes AMG. Last summer, the latest version of the engine was unveiled and reportedly, it produces up to 415 horsepower (310 kW / 421 PS) and 369 lb-ft (500 Nm) of torque.
The standard WRX will likely adopt a detuned version of the STI’s engine but we are not sure about its power. Currently, WRX currently comes with a 2.0-liter four-cylinder which offers a horsepower of 268 (200 kW / 272 PS) and a torque of 258 lb-ft (349 Nm).
Though, Subaru has been mum regarding its next-generation car performances, but previous reports suggest that the models will be offered with a manual transmission as usual.
