The 2005 FIA WTCC Race Of San Marino was the fourth round of the 2005 World Touring Car Championship season.

[1] Gabriele Tarquini and Peter Terting, who qualified fifth and seventh were both given ten-lace grid penalties for an incident in the previous race and an engine change respectively.

García started well and overtook polesitter Fabrizio Giovanardi at the line, with reigning champion Andy Priaulx jumping up to second in his BMW.

Championship leader Dirk Müller got the better of second row starters Jordi Gené and Augusto Farfus, with Roberto Colciago and James Thompson, in another Alfa following.

Thompson in fourth had just started to put pressure on Zanardi when he made a mistake and was passed by his two teammates, Rydell and Jason Plato in another SEAT.

Giovanardi thus took third, with Rydell fourth, whereas Farfus rejoined fifth and Zanardi had to settle for sixth, with the SEATS of Peter Terting and Plato completing the points.
