The Questor Grand Prix was a non-championship race for Formula One and Formula 5000 cars held on 28 March 1971 to inaugurate a new racing facility in California, the Ontario Motor Speedway, built by the Questor conglomerate.

Because of the smaller fuel tanks of the F5000 cars, the race was run in two heats of 32 laps, and the final result decided by a points system. Jackie Stewart qualified on pole for Heat 1 and finished runner-up behind Mario Andretti. Chris Amon set fastest lap. Andretti and Stewart again finished first and second in Heat 2 and Pedro Rodriguez set fastest lap, quicker than Amon's time in Heat 1. Andretti was declared the winner; with Stewart in second place and Denny Hulme third. Mark Donohue was the best-placed F5000 finisher in Heat 1, and Ron Grable best in Heat 2. Grable was also the best-placed F5000 driver on aggregate.

During free practice on Wednesday, Andretti had heavily crashed his Ferrari. The team chief mechanic, Giulio Borsari, managed to rebuild the car overnight by using the one of Andretti's team mate Jacky Ickx as a reference point with the aid of a local welder. After Andretti won the race, Borsari was awarded the Mechanic of the Race trophy along with a $500 prize. [1]

Hopes for a regular fixture rapidly faded due to financial problems. The Questor Grand Prix remained a one-off event and the Ontario Motor Speedway was never again used to host a Formula One race.

Christopher Arthur Amon was a New Zealand motor racing driver. He was active in Formula One racing in the 1960s and 1970s, and is widely regarded as one of the best F1 drivers never to win a championship Grand Prix. His reputation for bad luck was such that fellow driver Mario Andretti once joked that "if he became an undertaker, people would stop dying". Former Ferrari Technical Director Mauro Forghieri stated that Amon was "by far the best test driver I have ever worked with. He had all the qualities to be a World Champion but bad luck just wouldn't let him be".

<span class="mw-page-title-main">March 701</span> Formula One racing car

The March 701 is a Formula One racing car model, designed by Robin Herd with Peter Wright, and built by March Engineering. The 701 was March's first Formula One design – following their one-off March 693P Formula Three prototype of 1969 – and was designed and built in only three months. The March 701 made its race debut a month after its public unveiling, at the 1970 South African Grand Prix. In total, eleven 701s were constructed, with March supplying many privateer entrants as well as their own works team. The 701's career started well, March drivers taking three wins and three pole positions from the car's first four race entries, but lack of development through the 1970 Formula One season resulted in increasingly poor results as the year wore on. The 701 was superseded by the March 711 in 1971, and made its last World Championship race appearance at the 1971 Italian Grand Prix.
