Short of just printing cash, there are few better money makers than special edition sports cars right now. Porsche knows this and does it better than anyone in the business. Specialty 911 models like the GT3 and Targa 4S Heritage Edition are nearly impossible to get without paying a huge markup or knowing someone who can get your name on the reservation list. Porsche won't stop cranking out limited-edition 911 variants anytime soon, as evidenced by some recent spy shots from the Nurburgring in Germany.

These photos show a special 2022 Porsche 911 Carrera model, rumored to bring back the "Sport Classic" name. Porsche hasn't built a 911 Sport Classic since 2010 in the 997 generation. Only 250 copies were built, and are now worth far more than a standard 997.

This is not the first time we've spotted the 911 SC out testing, but the car looks far more production-ready than before. These latest shots show off more details on the car, including the iconic fixed ducktail spoiler. The front and rear bumpers ape those on the 911 Turbo S, but we know this is not a Turbo test mule because it lacks air intakes on the rear fenders. It looks like the SC will have a double-bubble roof and slightly different hood lines than a standard 992 911.

At the back, Porsche taped over a badge on the rear grille, which is likely the "Heritage" emblem used on the Targa Heritage Edition. As an homage to older 911 models, the prototype rides on classic five-spoke Fuchs-style wheels with a modern center-lock design.

It's still unclear what engine will power the 992 generation 911 SC. The 997 model used the same engine found in the Carrera S, tuned to produce an additional 23 horsepower. Unlike the Targa Heritage, which uses the Carrera S motor, we anticipate the SC will get the boosted 3.0-liter twin-turbo flat-six from the latest 911 GTS, producing 430 hp (30 hp more than the Carrera S). The 2022 911 SC should be revealed later this year.
