 They moved it to an assembly plant near Cagliari, where it resumed the production of the Spring, which was now based on the SEAT 850 Special.Because of this the engine displacement increased to 903cc with 47BHP, and it gained disc brakes on the front wheels and a higher top speed of 125 km/h (77.6 mph).Due to the 1973 oil crisis sales of sports cars in Italy went down, forcing ORSA to end the production of the Spring in 1975.
