In the 1920s Martin Máximo Pablo de Alzaga Unzué was as much known in the USA and Europe as in his native Argentina. A member of the official Bugatti team in the 1923 Indianapolis 500, he also raced in that year’s Italian Grand Prix, at the wheel of a Miller 122. He failed to make the placings in either event, but in 1924, driving a 4.9 Sunbeam, won the Coupe de l’Autodrome at Miramas near Marseilles, leading from start to finish.
‘Macoco’ de Alzaga had begun his career as a teenager just after the Great War, winning a sprint at La Plata in 1920 and the follwing year driving a Hudson into second place in the Gran Premio Nacional, Argentina’s most prestigious race.
He took the Sunbeam back home with him after his European sortie but met with little success.
