Porsche typically keeps to a suitably fast schedule when it comes to rolling out increasingly hard-core performance versions of the 911. After the 997 Carrera debuted in 2004, the GT3 version followed in 2006, and by the end of the 2007, Porsche had rolled out both the GT3 RS and GT2 versions. Then the facelifted 997.5 came out in 2008 and it was back to the start: the GT3 came in 2009, the GT3 RS and GT2 RS in 2010, and the GT3 RS 4.0 in 2011. But things have slowed down some with the latest 991 generation.

The new Carrera came in 2011 and the GT3 followed in 2012. By recent history's example, we should have at least two more hardcore models by now, but we don't. Maybe the engineers in Zuffenhausen have had their hands full fixing the spontaneous-combustion issues with the existing GT3, or maybe their attentions have been focused elsewhere altogether. But if these spy shots are anything to go by, it seems like they're back on the job.

Now we don't know if this prototype foreshadows a new GT3 RS or a GT2, but it sure looks more hard-core than the existing GT3 that many purists have derided as too soft, what with its automatic transmission and four-wheel steering.

What's the difference between a GT3, GT3 RS or GT2? We're glad you asked (even if you didn't). The GT3 is a more performance-focused version of the 911. The GT3 RS takes things a step further, but keeps the naturally aspirated engine. The GT2 packs twin turbochargers, like the 911 Turbo but without all-wheel drive. Porsche seems likely to do one or the other, and this could be either. But whichever it is – with the turbos or without, manual transmission or dual-clutch – it promises to be one of the most formidable performance machines on road or track.

      If this is the GT3 RS I can't even think about how the GT2 RS will look like

      The intakes in front of the rear wheels makes me think GT2, but the black tape on the hood and roof make me think they're hiding the graphics that were typical on the last gen GT3 RS. So who knows!

      This is obviously a GT2. This thing is going to be a complete monster. I foresee some production lap records being busted before long.
      • 1 Year Ago
      GT2 of course since it does have the 2 intakes for the Turbos.

      GT3 typically is narrow body, which this is not.

      It's the GT3 RS. Center exit exhaust is the GT3 calling card, the Turbo openings are just to help with track cooling. I remember hearing Porsche Product Manager say that a new GT2 would probably be worse than a Turbo S as having the rear wheels do all the work could make it worse as the GT2 has always struggled for traction, though a GT2 was not ruled out yet. Still most likely a GT3 RS.

        I hope they decide to make a hardcore 911 turbo instead of a GT2. A lightweight, track focused turbo RS would be awesome.
      The people claiming it to be turbocharged merely because of the air intakes have totally fallen for Porsche's intentions to throw you off the scent. The production car will use the same wider body as the Turbo. The bumpers are GT3 and the rear wing looks like a GT3 RS item as the GT2 wing has integrated air intakes. One more thing: the centrally-mounted exhausts point to it being a naturally aspirated engine as the layout of the turbocharged flat-six results in the tailpipes being on the left and right of the bumper. - Former Porsche magazine writer.

      Given the big scoops on the rear fenders, I'd say GT2 with a small bump in HP over the Turbo S and some more track-friendly bits.......I'd be surprised it they built another GT2 RS right now that might encroach a bit on the performance potential of the 918 Spyder.

      Wide and vicious, in test-mule black. Also betting it is likely the upcoming GT2.
