A source at Jalopnik linked to the homeground of Porsche, Stuttgart, has indicated that we can expect a limited edition Porsche 911 C4S-based widebody Supersport, complete with duck-tail spoiler and double bubble roof. It is not the only source indicating this. A second source at TeamSpeed forum indicates the exact same thing.
The new Porsche won’t be as hardcore as the GT3 or GT3 RS. The Carrera Supersport will have the same C4S-based widebody, but the positioning within the portfolio will be different more grandsport. Jalopnik indicates it will feature Fuchs-style wheels, a double bubble roof, a ducktail spoiler and a primer gray colored paint job. The interior will feature a retro throwback brown leather interior.
It is expected that we will see a very limited edition for a price tag of about £135,000 ($222,223 USD).
