Brabham dropped Fabi for 1985 and he initially struggled to find a team. His profile in Italy allowed him to rejoin Toleman (now heavily sponsored by the Benetton Group) when they belatedly joined the championship at the Monaco Grand Prix. Fabi drove the No. 19 Toleman Motorsports Group Toleman TG185-Hart 415T. The season got off to a late start because Toleman had lost their supply of tyres when Michelin pulled out of F1 at the end of 1984. They could not access Goodyear tyres and Pirelli would not supply them as they had broken a contract with the Italian company in mid-1984 and gone with Michelin. Benetton bought both Toleman and the Spirit team and transferred Spirit's Pirelli contract to Toleman. The late start meant the TG185 was never truly reliable, but Fabi's speed lead to the marque's only pole position, at the German Grand Prix, at the new Nürburgring. Fabi's race was ruined when a slipping clutch meant he was well down the order at the end of the first lap. The team failed to score any points and Fabi only finished twice (even these races were disrupted by mechanical problems). In 1980, World Champion Alan Jones, who also used a Hart engine in his Haas Lola, late in the season described it as "sending a boy to do a man's job" in F1 against the likes of Renault, Ferrari, BMW, Honda and TAG-Porsche. Fabi's best finish was twelfth at the Italian Grand Prix and he would again go unranked due to not scoring points.
