Why it matters

Bertone's 1970 Stratos Zero was a wedge-shaped, mid-engined concept that convinced Lancia's management and rally chiefs to adopt a similar car for competition. It led directly to the Stratos HF prototype of 1971 and the Stratos rally car.

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

History

The Zero was shown at the 1970 Turin Auto Show as a clean-sheet design by Marcello Gandini at Bertone. Lancia's public-relations director Sandro Fiorio and his son Cesare, the rally chief, lobbied managing director Ugo Gobbato to build a competition car on the idea. The car was reputedly so low that it drove under the barrier at Lancia's factory gates.

The Stratos HF prototype followed in 1971 with the same wheelbase of 2,180 mm, and was considered the first car built purposely for the World Rally Championship.
