After the Subaru WRX concept unveiling at the 2013 New York Auto Show, comes the first spy shots of a production ready prototype has been spotted on the nordschleife in Germany.

The styling and the tell tail quad exhaust pipes tell us that hiding under the camouflage is more than a WRX, it looks like this could be the fettled STI version.

The all new WRX, which should be launched later this year as a 2014 model, is rumoured to hold the same 2.0l boxer unit as both the BRZ and GT-86 toyota and is most definately been force fed from a turbocharger system.

Due to the lighter engine configuration and the chassis improvements should make this the lightest subaru to date, the WRX is rumoured to have around 270hp along with this fettled WRX STI of around 320hp.

The addition of the large wing will increase its downforce along with improved ventilation around the front wing will aid in reducing brake temperatures.

We expect the 0-62mph time to be under 5’s if they hit their targeted power output.
