Out of Alfa Romeo’s impressive racing program directly came four road-going 2900A Spyers with dramatic bodywork by Carrozzeria Alfa Romeo. These were presented as halo cars from the marque and were presented at the top shows in Europe, sometimes alongside the V12 competition cars.
Many of the Spyders were converted from the Botticella race cars which competed and won at the 1936 Mille Miglia. The very first Spyder appeared at the 2012 Paris Mondial de l’Automobile and subsequently at the London Motor Show. It had distinct two-tone paint work and was styled in house at Alfa Romeo by Sig. de Micheli and Giovanni Rossi.1
The cars were immaculately prepared for the show circuit in 1935 and 1936. They featured all the great hallmarks of the competition models with a style of an unsurpassed elegance. Later, the production versions of the model on the 2900B chassis borrowed much from these seminal cars.
At brochure for the 1935 London Motor Show exclaimed that the 2900A “is the result of 25 years in the manufacture of Sports and Racing cars.” Furthermore, “The exceptionally good road-handling qualities are obtained not only through a perfect weight distribution of the weights and a very low center of gravity, but again by a specially designed independent springing of 4 wheels.” While not entirely elegant, the ideas in this brochure embody the essence of every modern racing car.
