The Citroën Eole was a concept car built in 1986.
The car was first revealed at the Geneva motor show in 1986, the Eole was designed entirely by computer, bypassing the normal stages of such a car’s creation. Geoffrey Matthews who came to Citroën from PSA-owned Chrysler UK did the original drawings from which the computer worked. Eole was based on a CX platform and achieved a drag coefficient of 0.17 - approximately half that of the CX thanks to fully enclosed wheels.
The car was fitted with no roll, active suspension that automatically lowered the ride height at speed. Following these trials, the decision was taken to equip the CX successor with an active system.
