How to read this forecast
P50 is the model median. The outer shading spans P10–P90; the darker band spans P25–P75. These are model quantiles, not verified probabilities or observed sale prices. The calculation extends the modeled trend and volatility; it does not include new listings, vehicle condition or transaction costs.

Overview
Porsche designed the racer first and built the road quota around it.
The GT1 regulations required a road-going counterpart. Porsche met that requirement with a small series assembled by the racing department at Weissach rather than adapting a production 911 chassis into a racer.
Road cars retained the twin-turbo engine, double-wishbone suspension, large brakes and six-speed transaxle, with road equipment and reduced output. Porsche quoted 544 PS, 310 km/h and 3.7 seconds to 100 km/h.
The programme culminated in the GT1-98 race car's overall Le Mans victory in 1998. Later road cars mirror that evolution, which is why a catalogue entry must distinguish an early Straßenversion from a GT1-98.
