Formula One reaches its season finale this weekend at Interlagos, as the title goes to a last-round decider for only the second time this decade.
The last time it happened was in 2003, when Michael Schumacher needed just one point to clinch the title. This time the tables are turned, and it is his rival Fernando Alonso who needs that precious point to clinch back-to-back titles.

The Interlagos circuit first appeared on the championship calendar in 1973, after hosting a non-championship event a year earlier. Ronnie Peterson was on pole for the first championship race in 1973, one of nine pole positions for the Swede that year, smashing Jim Clark's record of six, set ten years previously.
Lotus teammate Emerson Fittipaldi thrilled the home crowd with victory, as he did in the 1974 race, but in 1975 he could only finish second to Sao Paulo native Carlos Pace, who won for Brabham. It was a historic result, as Brazilians had never previously finished 1-2 in a Formula One race.
