We recently showed you images of another version of the 911 (992) out testing. It seems Porsche is not done with the latest generation of their iconic rear-engine sports car. The 992 currently represents the pinnacle of Porsche 911 evolution and it seems the brand really wants this to be the most complete 911 yet. After all the usual versions of the 911, retro-inspired models make a comeback.

The model caught testing on the Nurburgring is expected to be a new iteration so the 911 Sport Classic. We see some distinctive features, the most notable of which are the ducktail spoiler and double-dome roof. The last 911 Sport Classic was from the 997 generation and was produced in 250 copies. It seems the upcoming retro-inspired 911 will have the Turbo S front bumper and the GTS rear bumper, along with other distinctive features, like the center lock wheels.

Just like the 997 SC, the upcoming car is expected to share the engine of the 2022 Porsche 911 Carrera GTS. This means that the 3.0-liter twin-turbo flat-six will produce around 475 horsepower (354 kilowatts).

The previous Sport Classic was a manual only, in order to celebrate the pure driving experience of classic 911 performance models. With this in mind, there is a good case for the 4.0-liter normally-aspirated flat-six to make an appearance, although that one will probably remain exclusive to the 911 GT3, GT3 RS, and GT3 Touring versions.

Just like many of the other 992 versions, the Sport Classic is expected to debut later this year or in the first half of 2022 and will probably have a limited production run of a few hundred cars. One thing we know for certain is that it will be another epic homage to the 1973 Porsche 911 Carrera 2.7 RS.
