The 2015 Subaru WRX/STi - Before the Detroit Auto Show

Ahead of the Detroit Auto Show, pictures the 2015 WRX/STi have been leaked onto the web. Judging from a spec sheet that was leaked late in 2013, this is most likely the "Launch Edition STi" sporting a gold BBS wheel package in the signature World Rally Blue Pearl color. The aggressive body lines, mean front fascia, and the lowered stance complete with the STi rear wing are likely to give this generation of Subaru's flagship line a menacing road presence.

However, the big question is, what will be powering this through the dirt and snow that STi's are always known for? Well, the question cannot be answered until the Detroit Auto Show. The one thing that is for certain is that it will sport a 2.5 liter turbo boxer, much like the outgoing STi. However, it is uncertain whether the previous EJ25 will carry into this generation, and if it does, whether or not there are improvements is still to be seen. There is also speculation that it may source the 2.5 liter engine from the Forester, much like the WRX is doing with its FA20DIT. In the case of the STi, it will be a turbo-charged, direct injection version of possibly the FB25 motor. 

It is also known that there will only be one transmission offered in the STi: a 6-speed manual gearbox. Subaru will not be offering a CVT version, as it is doing with the WRX. Whether or not it is any different than the outgoing 6-speed in the STi remains to be seen. Also, expect to see a DCCD (Driver Controlled Center Differential) that will enable the driver to set where they want the power to go. This should be different from the DCCD that is offered in to the CVT-WRX, as it will be geared for speed, not a transmission.

Edit: Subaru of America has just updated their website to note that the STi will have a 305-hp turbo boxer.

Edit: This is an alleged shot of the engine bay. It does appear to be EJ in nature without any signs of direct injection.
