The 12C, better known as Tipo C, was a Grand Prix racing car developed by Vittorio Jano. It was available in two versions, 12C-36 and 12C-37, whereby only two of the four 37’s were used. The 12C-36 made its debut in 1936 at the Grand Prix in Tripoli, the 12C-37 at the Coppa Acerbo 1937. .
While the 12C-36 was based on the 8C-35, the 12C-37 was a new development. The 36 instead of the 3.5-litre 8C-35 was equipped with a V12 engine with 4100 cc and 370 hp at 5800 rpm. The lowered successor had a 4475 ccm engine with 430 hp at 5800 rpm and roller instead of plain bearings. Mistakes due to improper handling prevented the start of the 1937 Grand Prix, and after Alfa Romeo withdrew his message, Jano took responsibility and resigned. The most important victories were achieved by the 12C 1936 at the Penya Rhin Grand Prix, the Milan-Grand-Prix, the Modena-Grand-Prix and the Vanderbilt Cup, driven by Tazio Nuvolari, who was also at the helm of the Milan-Grand-Prix in 1937. After a dispute with the team leader Enzo Ferrari,”the biggest driver of the past, present and future” (quotation Ferdinand Porsche) changes to Maserati. The biggest victories in 1937 were Antonio Brivio at the Valentino Grand Prix, Giuseppe Farina at the Circuito di Napoli and Carlo Felice Trossi at the Genova Grand Prix.
