Upon its 1966 release, Bosley Crowther called the film "a smashing and thundering compilation of racing footage shot superbly at the scenes of the big meets around the circuit, jazzed up with some great photographic trickery ... Mr. Frankenheimer belts you with such a barrage of magnificent shots of the racing cars, seen from every angle and every possible point of intimacy, that you really feel as though you've been in it after you've seen this film. Furthermore, the director and Saul Bass fill that mammoth screen from time to time with multiple graphics and montages that look like movies at a world's fair. Triple and quadruple panels and even screen-filling checkerboards ... hit the viewer with stimulations that optically generate a sort of intoxication with racing. It's razzle-dazzle of a random sort, but it works." However, Crowther concluded "the big trouble with this picture ... is that the characters and their romantic problems are stereotypes and clichés... You come away with the feeling that you've seen virtually everything there is to see in grand-prix racing, except the real guys who drive those killer cars."
