The 1977 season started in Argentina, and it was reigning world champion James Hunt who started off his title defence with pole position in his McLaren. Countryman John Watson shared the front row with him in the Brabham, and Patrick Depailler in the six-wheeled Tyrrell was third on the grid.
Watson took the lead at the start with Hunt second. Watson led for the first 10 laps until Hunt moved ahead and pulled away, with Mario Andretti's Lotus third, but soon the other McLaren of Jochen Mass took the place. Mass had to retire soon after with an engine failure which caused him to spin, and a suspension failure took teammate and race leader Hunt out three laps later. Watson took the lead again, but he also had suspension failures and let teammate Carlos Pace through. Watson eventually retired, and Pace struggled towards the end due to heat in his cockpit and was passed by Jody Scheckter's Wolf and Andretti, but the latter retired then with a wheel bearing failure. Scheckter took the first win of 1977, with Pace second, and home hero Carlos Reutemann completing the podium for Ferrari.
This was the 100th fastest lap set by a British driver.
This race marked the 5th Grand Prix win for a South African driver.
This was the Formula One World Championship debut for Canadian constructor Walter Wolf Racing, and also the debut Grand Prix win for Wolf - the first Canadian constructor to do so.
