He worked on the Fiat 131 Abarth Rally, set by Colucci as regards the chassis, taking it to the end of his career, which arrived in 1979.
At the end of 1978, following a clash with the engineer Aurelio Lampredi, Colucci resigned so that Limone was promoted to head of vehicle design and testing, in relation to the experience department.
In the meantime, he takes part in the development of a Group C car, the Alfa Romeo Sport Prototipo, derived from the Lancia LC2 and updated with all its contents to make it a winner, which, however, will never race on the track due to the management decisions of the Fiat Group managers.
In addition to the cars developed for track racing, he developed the Alfa Romeo 155 GTA Stradale, produced in a single model with the aim of stimulating the interest of the Alfa Romeo management in series production but this car will never have a productive following.
Finally, he participated in the development of the racing version of the Alfa Romeo 156, designed for the ETCC and WTCC championships of the early 2000s.
