Škoda
Spider I

Why it matters

The Škoda Spider B5 was a one-off open two-seater racing prototype built by AZNP, today Škoda, after the 1972 FIA class merger and a 2,000 cm³ Czechoslovak limit. Škoda describes the Spider B5 and Spider II as among the fastest and most exotic cars on Czechoslovak tracks in the late 1970s.

How rare is it?

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

The car used an aluminium body that folded up at the front and rear and modified parts of the Škoda 110 L. Its engine was a prototype OHC four-cylinder from the Škoda 720 project, producing 150 hp and mounted in front of the rear axle. The displacement grew over the seasons from 1.5 to 1.6 to 1.8 litres, and a 2.0-litre engine arrived in 1975.

The unpredictable handling earned it the nickname "Skokan" (jumper). Jaroslav Bobek drove it to numerous circuit and hill-climb wins in Czechoslovakia and abroad, and the Bobek family continued to race it until 1976. It later became an exhibit at the factory museum.
