The body became structure
Porsche bonded a glass-fibre body to a steel box frame and placed the engine behind the seats. The 904/4 gave owners a five-speed, four-cam car they could drive to a race. Porsche built 106 four-cylinder examples.

Estimate band for good road cars. 7 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. Estimate for authentic four-cylinder cars with traceable identity. Works history, original engine and body material, restoration scope and event eligibility can move a car outside the band.
Instrument calibration for this file is in progress — the terminal above reads the documented record directly.
Ledger excludes estimates, no-sales and works six- or eight-cylinder cars. Published USD totals are recorded without adjustment.
Overview
Ferdinand Alexander Porsche designed the low body around a mid-engine package and a frontal area of only 1.4 square metres. Heinkel helped manufacture the glass-fibre shells, which Porsche bonded to pressed-steel frames.
The 904 opened its 1964 Le Mans record with four cars at the head of the two-litre class. At the Targa Florio, Antonio Pucci and Colin Davis won overall in a four-cylinder 904, while Porsche also used six- and eight-cylinder works versions to develop the next generation of prototypes.
