Fiat
ESV experimental safety vehicles

Why it matters

Fiat's ESV programme was its answer to the US safety-vehicle competition of the early 1970s. Fiat built three prototype families from production cars, none intended for sale, to explore protective structures, shock absorption and a rigid survival cell.

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

In 1971 the US safety agency launched a competition for cars giving occupants the best chance of surviving a crash. European and Japanese makers including Fiat, Mercedes, Volkswagen, Datsun and Honda joined, basing their entries on strengthened production cars. Fiat's three prototypes were the ESV 1500, ESV 2000 and ESV 2500, named by weight class.

The ESV 1500 (about 680 kg, 500/126 mechanics, rear engine) was presented at the 1972 Washington conference and 13 units were built. The ESV 2000 (about 907 kg) was based on the Fiat 128, and the ESV 2500 (about 1135 kg) on the Fiat 124. Fiat had built 47 units in total by 1974, and the programme cost over 4.5 billion lire.

Identification guide

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

The three types are told apart by base car: the ESV 1500 uses 500/126 mechanics, the ESV 2000 is a five-door 128-based car with a curved windscreen and roof bulge at the B-pillars, and the ESV 2500 is 124-based with a curved windscreen, reinforced centre pillars, robust bumpers and sides thickened by 5 cm.
