Daihatsu
P-5 racing prototype

Why it matters

The P-5 was Daihatsu's works prototype sports racer of the late 1960s and won the GP-I class at the 1968 Japan Grand Prix. Daihatsu kept one car and had it restored to running order by its own staff in 2018–2019.

How rare is it?

Six separate kinds of rarity – never combined into one number.

Each kind of rarity is rated separately and never combined.

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

Daihatsu built at least four P-5s. At the 1967 Japan Grand Prix the cars were disqualified with mechanical problems; in 1968 car No. 15 finished 10th overall and won the GP-I class, and a P-5 was third overall in the Suzuka 1000 km. In 1969 it took its best result, second overall in the Suzuka 1000 km.

Daihatsu kept one car, cosmetically restored about ten years before 2019 but without its engine. After an original R29B engine was found in 2018, employee volunteers at the R&D centre completed the car, which was shown running at the 2019 Automotive Engineering Exposition in Yokohama.
