Porsche was at the Nürburgring the other day to perform a series of tests on a prototype for the 911 GT3 facelift.

Unsurprisingly, Porsche is playing a game of spot the difference when it comes to the cosmetic tweaks for the 991.2 GT3. The folks from Zuffenhausen have already updated the lesser versions of the 911 range and now they are putting the finishing touches on the 911 GT3. From what we are seeing so far, only the front fascia has been mildly revised by adopting modified LED daytime running lights and a different shape for the air intakes.

The most important news concerning the 991.2 GT3 will be the adoption of a six-speed manual gearbox that will be offered alongside the PDK. This is more than just gossip as Porsche has already confirmed it will offer the 911 R’s manual for the GT3 (but not for the GT3 RS).

While more and more Porsches are embracing turbocharged engines, the 911 GT3 isn’t going to be one of them, according to Andreas Preuninger who is the man in charge of the company’s GT cars. The current GT3 version is motivated by a naturally-aspirated 3.8-liter, flat-six engine pushing out 475 horsepower, but some things could change with the arrival of the facelift.

When are we expecting the 991.2 GT3? Chances are it will be out towards the end of the year as a 2017MY. Maybe we’ll get to see it as early as October during the Paris Motor Show.
