Recently the blogosphere has been alive with chatter that the next-gen Subaru WRX will get the FA motor developed for the Subaru BRZ, and this is one instance when there's logic behind the rumor. The FA engine can sit a lot lower in the car because it's more compact. A lower engine has many advantages, chief among them the ability to shove the mass farther rearward in the car for better balance. Better still, Subaru engineered the FA for higher compression from the start, so it should tolerate the amount of forced induction required to take it from 200 hp in the BRZ to the expected benchmark of 265 hp. And let's just say here that we'd bet Subaru designed its latest Impreza chassis with the WRX (not to mention the STi) in mind, and we'd bet the newest WRX will be lighter and more nimble as a result. A bonus: Fuel economy should jump a good 15 percent.
