Turbo, pared to structure
Porsche Exclusive removed 180 kilograms from the 964 Turbo and raised output to 381 PS. Eighty-six were built, each rear-driven. Options could add comfort back, so specification matters as much as mileage.

Band and axis shown in USD. Sale positions use indicative fixed-rate conversion to USD; sale readouts retain recorded currencies. Estimate for documented, usable cars. Mileage, retained lightweight equipment and factory special-order provenance can move an individual car beyond the band.
Instrument calibration for this file is in progress — the terminal above reads the documented record directly.
Auction totals are recorded as published by the houses. No currency conversion applied.
Overview
Porsche Exclusive manager Rolf Sprenger proposed a light, more powerful Turbo while the company was under financial pressure. A Geneva study in March 1992 translated lessons from the 964 Turbo-based IMSA Supercar programme into a road-legal small series.
Production ran from July to November 1992 for the 1993 model year. The result kept the 964 Turbo's single-turbo layout but removed comfort equipment, reinforced the shell and raised output by 61 PS.
