Based on the Fiat 1400, the Daina or Gran Sport is a carefully crafted special. It was the largest of the models offered by Siata and featured simple aluminum bodywork by Stabilimenti Farina.
At their Turin facility, Siata beefed up the Fiat 140 with extra cross members and reduced the drive shaft length. They also retained the standard Fiat suspension setup with double wishbones up front.
In this chassis was fitted with a Fiat 1400cc engine that had a unique over-head valve arrangement that was unique to Siata. Also fitted was Weber Carburetors that raised the stock power from 60 to 72 bhp. This was attached to the stock 4-speed manual or a custom Siata 5-speed box.
Later, this model was replaced by cars fitted with the Fiat 'Ottu Vu' V8 engine.
In 1926 Siata; Societa Italiana Applicazioni Trasformazioni Automobilistiche was founded by Georgio Ambrosini in Turin. This company was begun to manufacture tuning accessories for Italian vehicles. The company was famous for their cylinder heads with overhead valves for the 500A and they also used superchargers for some applications. Several prototypes were constructed based on the Topolino which included some examples of the 500 Gran Sport in 1937 which was a spider with a rocket-like body and a 636cc engine. One of these models, with a body by Zagato won its class in the 1937 Mille Miglia driven by Piero Dusio.
From 1950 until 1958 the Siata Daina was produced and built in both Coupe and Convertible bodystyles. Power came from a Fiat 1400 pushrod engine that was tuned by Siata and joined to a floor shift five-speed gearbox. A four-speed gearbox finished off the sports model. The majority of the convertibles were given coachwork by Stabilimente Farina while most coupes were bodied by Bertone.
The Siata Daina was introduced to complement the smaller Amica. A GT car, the Daina was built both as a coupe and a trasformabile (convertible). Both of these bodies were created by Stabilimento Farina, while the mechanical side was once again taken from a Fiat, this time the 1400. When Stabilimenti Farina closed production is was passed on to Carrozzeria Balbo. The engine inside the Daina was a 1393cc unit with 65bhp and a five speed gearbox. The Rallye 1400 model in 1951 was modified in the body-style so it was more similar to the MG TD. The Daina range was also further enhanced with the addition of versions with stretched chassis', a limousine that stretched to accommodate six seats, and an estate version.
The design was once again updated in 1952 with the release of the Daina Sport, a two seat coupe, and the 1400 Gran Sport' a cabriolet. Once again, both versions were by Farina, and utilized the 1400 mechanicals and engine, but the engine in the Daina Sport was increased to 1500cc and now produced 75bhp. Several cars were also built using American engines, including units from Crosley and Chrysler, while the final few production vehicles had bodies by Bertone. The total production numbers were around 200 cars.
A spider version was also a built, a GT saloon with the body by Bertone along with a variant with a Chrysler powerplant and around 32 of these examples were built.
