AutoBlog: Next Subaru WRX previewed by Japanese Legacy's 2.0L turbo?

2011 Subaru Impreza WRX STI

The next-generation Subaru WRX and WRX STI are still shrouded in a cloak of secrecy. Or is it indecision? Either way, Car and Driver is reporting that when Subaru eventually pulls the wraps off whatever is going to wear the WRX badge, there's going to be a turbocharged version of the 2.0-liter FA-series engine underhood, a derivative of the naturally aspirated engine that's found in the Subaru BRZ.

How does the venerable buff book know this? Because the turbo'ed flat-four has already appeared in the Japanese domestic market Legacy, making 296 horsepower and 295 pound-feet of torque, mated to a continuously variable transmission. C/D says that engine differs from the one in the BRZ in that it uses Subaru's own direct injection system rather than one coming from Toyota.

In the standard WRX, horsepower numbers are expected to be a bit lower than in the JDM Legacy, though the STI version will probably see power boosted. C/D says the new 2.0-liter engine is supplanting the 2.5-liter Subaru has been using due to fuel economy considerations, though there's also something to the notion of consolidating powertrains to reap greater efficiencies in manufacturing.
