The last road-legal racer
The 906 is a two-litre prototype with lights, luggage space and road papers because the rulebook required them. Sixty-five chassis covered six-cylinder cars, fuel-injected works cars and four experimental eights.

Model data: Jul 2026 · 8 documented sale anchors. Modeled history between documented sales.
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.

Estimate band for good road cars. 4 documented sales since 2019 plotted below.
Band and axis shown in USD. Sale positions use indicative fixed-rate conversion to USD; sale readouts retain recorded currencies. Indicative band for recognised six-cylinder cars with documented history. Works provenance, major results or unresolved reconstruction can move a car far outside it.
Instrument calibration for this file is in progress — the terminal above reads the documented record directly.
Reported auction results are retained in USD. Buyer-premium treatment follows each auction house's published result.
Overview
The 906 followed the 904 but retained little of its construction. Under Ferdinand Piëch's supervision, Porsche moved to a tubular frame with a thin, unstressed glass-fibre shell and installed a six-cylinder engine derived from the 911 programme.
Porsche presented the Carrera 6 to the press in January 1966. Customer demand absorbed the homologation run quickly, while works development added fuel injection, long-tail bodywork and experimental eight-cylinder engines.
The car won the Targa Florio outright and helped Porsche take the 1966 two-litre sports-car and prototype categories. The 910 replaced it at works level, but private owners raced individual 906s for years.
