He is the elder brother of Corrado Fabi, also a racing driver; Corrado shared the 1984 Brabham drive with him: since Teo was already committed to a programme in CART racing, Corrado stood in for the races which clashed with his CART commitments.
Teo also had a successful sports car racing career, culminating in winning the 1991 World Sportscar Championship for TWR Jaguar.
