Siata  Siata ("Società Italiana Auto Trasformazioni Accessori" in English "Italian Car Transformation Accessories Company") was an Italian car tuning shop and manufacturer founded in 1926 by amateur race car driver Giorgio Ambrosini. Siata initially sold performance parts to modify and tune cars manufactured by Fiat. After World War II, the company began making its own sports cars under the Siata brand until its eventual bankruptcy following the first Arab oil embargo in the mid-1970s. Production of the Siata's first wholly original design the Siata Amica began in 1948 and continued through 1952. The Amica was powered by a Fiat 500 cc engine capable of producing 22 horsepower with an optional 750 cc unit producing 25 horsepower. The Amica was available in both two-seater convertible/spider and coupé configurations. A specially modified Amica known as the "Fiat Siata 500 Pescara" won the 1948 "Italian Road Racing Championship" fitted with a five-speed manual gearbox and a modified 500 cc engine producing 40 horsepower. Only two 500 Pescaras were ever built with only one surviving model. The surviving car also competed in the 1991 Historic Millie Miglia. The Daina was based on heavily modified Fiat 1400 mechanics; the frame was reinforced and shortened while the engine was tuned by Siata. The Daina could be had with a 1.4L (1,395 cc), 1.5L (1,500 cc) or 1.8L (1,817 cc) overhead valve I4 engine, all of which were sourced from Fiat. From 1950 to 1958 there were approximately 50 Daina Series cars produced. However, only a few of the Series were produced after 1953. About 20 Daina Sport (coupes) are thought to have been built, only six are known to exist today. A cabriolet version called the Gran Sport comprised most of the Daina Series cars. The Gran Sport had a steel body with an aluminum hood designed by Stabilimenti Farina (3 all aluminum bodied Gran Sports were made as well) but when they closed in 1953, Bertone took over production with a coupe model of their own design called the "Sport". Following the Amica, Siata introduced the 300BC Barchetta Sport Spider in 1951. The Barchetta Sport Spider was designed by Mario Revelli de Beaumont and built by Nuccio Bertone and Rocco Motto. Around 50 production models were created and predominantly featured either a 750 cc Crosley or 1100 cc Fiat engine.
