We've seen several 911 prototypes on the road in various stages of completion recently, including one that has us [scratching our heads]() a bit. But this? This one is especially weird. From just a glance, you can tell there's more going on here than fake headlights and hidden details. Let's start with the biggie: this is not a 992 body, but a 991. Why would Porsche be using a last-gen car as a test mule? Excellent question. And the hood that makes it look conspicuously Nissan-like could very well be the answer. You see, a couple of months back, Porsche registered trademarks for both [Flachbau]() and Flachbau RS. Translation? Slantnose. ![]() **Stefan Baldauf/SB-Medien** Between the nose and that not-quite-whale of a tail, there's definitely something going on here. Porsche has already dipped into the Slantnose well in modern times—the company did a [track-only tribute called the 935]() back in 2019—but since we're looking at a road-legal GT2 RS being used as a mule, it's entirely possible (though certainly not guaranteed) that this could be a full-fledged road car. Whatever this mystery mule is hiding, the use of a previous-gen body suggests it could be some time before we see something resembling a final product—perhaps as a send-off for the 922 when the time comes?
