It’s widely known (or at least somewhat known) that Porsche has been incrementally updating the 911 “992” series. Recently, we’ve spotted several 911 prototypes on the streets in different stages of development, including one that has us a bit puzzled. However, this one is particularly unusual.
At first glance, it’s clear that there’s more at play here than just fake headlights and concealed details. Let’s focus on the key point: this is not a 992 chassis, but a 991. Why would Porsche utilize an older model as a test vehicle? That’s a great question. The hood, which has a striking resemblance to Nissan designs, might hold the answer. A few months ago, Porsche filed trademarks for both Flachbau and Flachbau RS.
In other words, Slantnose.

Between the distinctive front and the somewhat whale-like rear, there’s certainly something interesting happening here. Porsche has previously explored the Slantnose concept in modern times — notably with a track-focused homage called the 935 back in 2019 — but since this is a road-legal GT2 RS being utilized as a prototype, it’s quite possible (though not assured) that this could evolve into a legitimate road car.
Regardless of what this enigmatic prototype is concealing, the choice of an older body indicates it may take a while before we see anything close to a final version—possibly as a farewell for the 922 when the time comes.
