In the early 1930s, the Carrozzeria Brianza was part of the Zagato company. Ugo Zagato, the founder of Carrozzeria Zagato, was in a financial straitjacket. The well-to-do racing driver family Ascari gave him financial help, so that Zagato was able to correct his problems by 1933.
The name Ascari is closely associated with racing and Alfa Romeo. In 1919 Antonio Ascari, the son of a Lombard grain merchant, began his career as a racing driver. In 1923 he won the Cremona race with an Alfa Romeo P2. His son, Alberto Ascari, took 13 Grand Prix victories and won two world championship titles. The Carrozzeria Falco Vittorio Ascari belonged to the Ascari family until it was taken over by the Carrozzeria Touring in 1923. Zagato formed the Carozzerie Zagato from the Ascari company Dux. The Carrozzeria Brianza remained active on the market until 1938 and worked for Alfa Romeo, Maserati and Lancia.
The best-known model of the Carrozzeria Brianza was the Alfa Romeo 8C 2600 Monza Spider Brianza, which won the Mille Miglia in 1934. From the body forge came an Alfa Romeo 8C 2300 Spider and an Alfa Romeo 6C 1750 Spider. The remaining Brianza models still in stock today are sold at top prices at auctions. An Alfa Romeo 8C-35 Grand Prix in good original condition from the 1930s was sold at an auction for 9.4 million dollars (!!!!). An Alfa Romeo 8C 2300 Monza Spider Brianza, of which the coachbuilder had only built ten vehicles, earned $6.71 million in 2010.
