It marks the beginning of the cooperation with Règie Renault. The car went into production in 1986 as the Renault 21.
The name is inspired by the door opening. Usually four-seater coupé have very long doors that take much room to be opened and that permit the entrance in two separate events: back seats first and then front seats.
Here there's only a gull-wing door that allows contemporary entrance for front and back seats.
For the first time, on the Gabbiano you can see the glass windows that completely wrap up the compartment and this characteristic will be reproduced in many following prototypes.
