Fabi's Indy car season in 1983 rekindled Formula One teams' interest. With help from Italian dairy company Parmalat, which insisted on having an Italian driver in the team, he joined MRD International in 1984 to drive the No. 2 Brabham BT53-BMW M12 as the number two driver to reigning World Champion Nelson Piquet. He also continued to drive in the &lt;a href="Champ%20Car"&gt;CART/PPG World Series&lt;/a&gt; for Forsythe Racing and missed three Grands Prix. In those races his younger brother, Corrado Fabi, drove in his place. The mixed approach led to disappointing results in both categories and mid-season saw Fabi decide to concentrate solely on Formula One. Prior to the change, Fabi's best finish was ninth at the 1984 French Grand Prix and his best start was a sixth at the South African Grand Prix. His performances improved, including a strong run at Italian Grand Prix where he ran second behind Piquet in the first half of the race before retiring with engine failure, the major problem for Brabham during the year. Fabi scored points on three occasions, with a best finish of third at the Detroit Grand Prix and was twelfth in points with nine.
