1958 Argentine Grand Prix

The 1958 Argentine Grand Prix was a Formula One motor race held on 19 January 1958 at Autodromo Municipal Ciudad de Buenos Aires Circuit. It was race 1 of 11 in the 1958 World Championship of Drivers and race 1 of 10 in the 1958 International Cup for Formula One Manufacturers which was introduced for that year, without including the Indy 500. The sixth Argentine Grand Prix was held on the #2 four kilometre variation of the circuit, over 80 laps for a total race distance of 313 kilometres.

The 10-car-race was won by British driver Stirling Moss, who, in absence of his Vanwall team, drove Rob Walker's privately entered Cooper T43-Climax. Apart from being the first World Drivers' Championship race win for Cooper as a constructor it was also the first win for a rear-mid-engined car in Formula One, the first in a Grand Prix since the 1930s Auto Union racing cars, the first F1 win for a car entered by a privateer team, the first win for a car powered by an engine built by another manufacturer and the first win for a British car with a blue livery, deviating from the traditional green colour used by British teams until then, apart from Germans often racing as Silver Arrows rather than in white. Moss took his seventh Grand Prix victory by 2.7 seconds over Italian driver Luigi Musso (Ferrari 246 F1). Musso's British teammate Mike Hawthorn (Ferrari 246 F1) was third.
