The Agusta A.104 Helicar was an Italian prototype light helicopter first flown in December 1960.
The A.104 was a slightly enlarged version of the A.103 and added a second seat beside the pilot’s seat.
The cockpit was enclosed by a perspex bubble with the engine at the rear and the tail rotor carried on an enclosed boom.
Two piston-engined prototypes were built, followed by a single example of a turbine-engined variant designated A.104BT.
No production resulted.
