Production

Every figure says what it counts.

Independent counts (e.g. engine and colour) are never combined into a calculated figure. Surviving examples are never presented as original production.

History

Porsche developed the car from the 930 Turbo for the 1976 Group 4 season and kept it in the range for 1977. For the Trans-Am and IMSA GTO series a small number of cars were prepared with Group 5 (935) parts as the 934/5, which dominated the 1977 Trans-Am championship.

Identification guide

How to tell an original from a replica or later conversion.

The 934 is built from a standard 930 bodyshell with the production rear spoiler, so it looks close to a road Turbo, but almost everything else was changed: the suspension has solid mounts and nylon bushings with adjustable anti-roll bars. Cars with 935 parts for American racing are listed separately as 934/5.
