Last month, we got our first glimpse at the Subaru Impreza Sedan concept car, and it looked pretty good. In all likelihood, the new Impreza will also spawn the next-gen WRX and WRX STi. Word on the street suggests that the new STi might be a hybrid that bows in during the 2017 model year.
The next WRX STi is tipped to use a 2.0L FA20 boxer flat four, combined with an electric motor to make a total of about 326 hp. That would be 21 hp more than the U.S. version makes now. The car is also said to get Subaru’s first automated dual-clutch manual transmission. Rumors suggest that a plug-in hybrid model might even be offered later.
If it holds true, it sounds like Subaru is going for both the performance and economy benefits of a hybrid system with the next gen WRX STI.
