The 1979 Argentine Grand Prix was a Formula One motor race held on 21 January 1979 at the Autódromo Municipal Ciudad de Buenos Aires. The race had to be restarted because there was a huge crash at the second of the very fast esses after the pit straight that took off a number of drivers, including Jody Scheckter, Nelson Piquet, John Watson, Patrick Tambay and Mario Andretti. After qualifying, James Hunt's WR7 was declared illegal, as the clutch-driven impeller blades which drew air through the air coiler were ruled an 'aerodynamic device'. Wolf mechanics modified the fan, and the car was allowed to start.
