Race Report The first Formula One race held at Jacarepagua was held in typically extreme weather conditions of January in Rio, meaning the race was held in both hot and humid conditions. Ronnie Peterson took the pole position in the leading Lotus ahead of James Hunt in the leading McLaren, teammate Mario Andretti in the other Lotus, Carlos Reutemann in the leading Ferrari, Patrick Tambay in the second McLaren and Gilles Villeneuve in the other Ferrari. Peterson got off to a poor start from the pole and dropped back to 4th, whilst into the first corner it was Reutemann from 4th on the grid who got the best start and lead the first lap for Ferrari ahead of Hunt, Andretti, Peterson, Tambay and Villeneuve. Hunt in the leading McLaren and Andretti in the leading Lotus were running 2nd and 3rd behind Reutemann, until Hunt was forced to pit for tyres whilst Andretti soon started to suffer from gearbox problems and dropped to 4th, handing their 2nd and 3rd places over to home favourite Emerson Fittipaldi and reigning world-champion Niki Lauda respectively. Peterson eventually retired after a collision by lap 16. The hot and humid conditions had eventually caused Hunt, Tambay and Villeneuve in the other Ferrari to all spin off and crash by lap 36. Reutemann meanwhile had no challengers for the lead all race long, and won by a comfortable margin ahead of former double world-champion Fittipaldi, Lauda, Andretti in the remaining Lotus, Clay Regazzoni in the Shadow and Didier Pironi in the Tyrrell.
