There were six weeks between the South African and Spanish GPs with the Race of Champions at Brands Hatch, the Questor Grand Prix at Ontario in California and a minor event at Oulton Park. At Brands Hatch Emerson Fittipaldi raced the Lotus-Pratt & Whitney 56 gas turbine car. The race was won by Clay Regazzoni in a Ferrari. The Californian race - which was run with F1 cars alongside Formula 5000 machinery - was won by Mario Andretti in a Ferrari, while the race at Oulton had only handful of cars (not including the Ferraris) and was won by Pedro Rodríguez's BRM. The V12 engined machines were very competitive against the Cosworth V8-engined cars.

The same was true at MontjuïcPark with Jacky Ickx and Clay Regazzoni on the front row in their Ferraris with Chris Amon's Matra. Jackie Stewart's Tyrrell shared the second row with Pedro Rodríguez's BRM while the third row consisted of Jean-Pierre Beltoise's Matra (who had now got his racing license restored after missing the early races of the year after his license was suspended following the sportscar crash in Buenos Aires which resulted in the death of Ignazio Giunti), Peter Gethin in a McLaren and Mario Andretti's Ferrari. Six of the first eight cars had V12 engines.

The race was a rather different matter. however, as Stewart burst through to second place at the start, chasing Ickx. On lap six he forced his way into the lead. Behind the leaders, Amon overtook Regazzoni for third place on lap three, but then the order settled down. Stewart began to increase his lead over Ickx while Amon ran third. Regazzoni went out on lap 13 with a fuel pump failure which promoted Rodríguez to fourth place with Andretti fifth and Denny Hulme sixth in his McLaren. In the mid-race Andretti disappeared with an engine problem and so Hulme moved to fifth place and Beltoise took sixth. In the closing laps Ickx closed the gap to Stewart but he was still 3.4secs behind at the finish.
