the grid in his McLaren TAG-Porsche, the Ferrari of 1985 World Championship runner up Michele Alboreto fifth, and Marc Surer in his Brabham-BMW rounding out the top six qualifiers. Outgoing World Champion Niki Lauda was 16th on the grid in his McLaren. Alan Jones ended up 19th on the grid after engine and turbo problems throughout practice and qualifying. The slowest qualifier for the race, Huub Rothengatter in the Osella-Alfa Romeo, was 10.473 seconds slower than Senna with a time of 1:30.319. With only 25 cars appearing for the race (the RAM and Zakspeed teams did not contest the last two races of the season - indeed RAM would never race Formula One again), all cars that attended qualified for the start. Race The race of high attrition, which was run in heat, was won by Rosberg driving the Williams-Honda; it would turn out to be the last victory (and last fastest lap) of his Formula One career. Rosberg was the only front running driver to finish strongly and one of only eight cars to be classified. It was the fifth and final Grand Prix win of Rosberg's career and confirmed his status as a street race specialist with three of his previous four wins being on the streets of Monaco (1983), Dallas (1984), and Detroit earlier in the 1985 season. Rosberg had some technical problems which could have lost him the race, his race engineer, Frank Dernie suggested a strategy to minimise loss of time. Rosberg gave the winner's trophy to Dernie. On the penultimate lap, Ligier-Renault driver Philippe Streiff tried to overtake his senior team-mate Jacques Laffite for second place and, as result of this manoeuvre, Streiff's front wheel axle was severely damaged. With fourth placed Ivan Capelli a lap down in his Tyrrell-Renault, Streiff managed to limp his Ligier JS25 home and retain third place despite having only three wheels firmly attached to the car, with the front left wheel bouncing up and down over the course of the last lap, but somehow remaining attached to the car. It would remain a career best finish for Streiff. Ligier team boss Guy Ligier, not impressed that Streiff had almost taken out both team cars at the end of the race when they were both assured of a podium finish, would not offer the Frenchman a drive for . A delayed Stefan Johansson finished fifth in his Ferrari ahead
