=== Design and development by Ferrari ===
The ASA 1000 GT originated in a late 1950s experimental project by Ferrari engineers to create a less expensive, compact alternative to existing Ferrari [[Grand tourer|GT cars]]. This project was designated "854"  by the factory (for 850cc, 4 cylinders), however it was commonly but unofficially named "Ferrarina," meaning "Little Ferrari."<ref name=":4">{{Cite journal|last=Paddock|first=Lowell|date=July 1983|title=La Ferrarina|journal=Automobile Quarterly|volume=21|issue=3|pages=284–291}}</ref>

The "Ferrarina" engine was derived from a late 1950s experimental [[Inline-four engine|inline-4]], designated Tipo 122. This was basically a four-cylinder, {{convert|850|cc|cuin|abbr=on}} slice of a [[Ferrari Colombo engine|Colombo V12]] from a Ferrari [[Ferrari 212 Inter|212]], with a bore and stroke of 65 x 64mm and supplied by two [[Weber carburetor|Weber]] 38DCO carburetors. The Tipo 122 engine produced {{Convert|68|hp|kW}} at 7000 rpm. The Tipo 122 was followed by the more powerful and slightly higher displacement Tipo 125 and 126 engines. The Tipo 126 engine displaced 973 cc and produced {{Convert|86|hp|kW}} at 7000 rpm. These engines were tested in the "Ferrarina" prototype, a 2-door [[notchback]] [[Coupé|coupe]] on a [[Fiat 1100]] or [[Fiat 1200|1200]] chassis with a [[Pininfarina]] body, which was used by [[Enzo Ferrari]] as his personal transportation for some time in the late 1950s.<ref name=":1" /><ref name=":4" /> The final engine design was completed in 1960 as the Tipo 141, with 1032cc displacement, bore and stroke of 69&nbsp;mm x 69&nbsp;mm, a [[Overhead camshaft|single overhead cam]] and two Weber 38DCOA carburetors. According to Ferrari's records, this engine produced {{Convert|100|hp|kW}} at 7200 rpm with a 9:1 [[compression ratio]].<ref name=":1" />

Following Ferrari's development work on the 854/"Ferrarina" prototype, a new prototype called the "Mille" ("one thousand" in Italian) was shown at the 1961 Turin Auto Show on the [[Gruppo Bertone|Bertone]] stand. The Mille was an entirely new car based on the 854 project, with 2-door [[fastback]] [[coupé]] bodywork designed by [[Giorgetto Giugiaro]] at [[Gruppo Bertone|Bertone]].<ref name=":1" /><ref name=":4" /> Although this prototype had no Ferrari badging, its design echoed contemporary Ferrari GT models and the origin of the design within Ferrari was well publicized.<ref name=":4" /> Despite positive publicity and official support of the project from Ferrari, at the time of the Mille's debut there were no plans for Ferrari to mass-produce the design. Ferrari engineers had planned around annual production of 3000-5000 cars, which would sell for approximately US$2600 each. Not only was the Ferrari factory inadequate for this kind of volume production, Enzo Ferrari was unwilling to expand it in order to produce the Mille. Even before the Turin debut of the Mille, Ferrari had begun searching for another company that would buy the design and bring it to market.<ref name=":4" />
