Wingless 2013 Porsche 911 GT3 Spotted during cold-weather testing again

Our trusty Teamspeed spies share with us today the new Porsche 991 based GT3 prototype testing on wintery public roads. In these photos we can clearly see the typical GT3-style front bumper and the staple centered twin exhaust pipes. This prototype did not have the large rear affixed as he other prototype we spotted last month but we can assure you the new GT3 will have one as have all preventions generations of GT3’s.

Power is expected to be around 450 horsepower and as mentioned earlier in the week, August Achleitner, the 911 project chief, confirmed that Porsche’s motorsport division is currently testing both manual and PDK versions of the new GT3. Only one transmission will ultimately be offered for sale, and Achleitner reckons the PDK is the favorite to get the nod.
