Chassis 101

The first model of this type was manufactured in March 1950 and was first campaigned on March 26, 1950, during the Inter-Europe Cup run at the Monza Autodrome. With Guido Scagliarini, driver and associate of Carlo Abarth, at the wheel, they won their category. This car also took part of the 1950 Mille Miglia, where it did not finish.^[2] Carrying starting number 533, it was fitted with temporary nose and tail extensions for improved aerodynamics, made by in-house coachbuilder Giuseppe Manera.^[3]

The engine in this car is a Fiat 1100 B engine fitted with a Cisitalia head, a dry sump, two Weber carburetors, and producing about 80 hp (59 kW).^[3] This car is currently in the O'Sullivan Square Museum in San Diego.

Chassis 102

This car, which has chassis number 102, is in fact the third and last example made. It differs in a number of ways, mainly the result of having a 2,330 mm (91.7 in) wheelbase rather than the original's 2,210 mm (87.0 in). It is presumed that this car was intended for the personal use of Carlo Scagliarini, brother of the driver and partner of Carlo Abarth, after it was retired from competition. The engine was similar to the one installed in chassis 101, although this unit was tuned by S.I.R.C.A. (Societa Italiana Rappresentanze Commercio Automobili) of Milano.^[3]

The just finished, still unpainted car competed at the 1950 Mille Miglia (listed as an "Abarth 204/A"), where it carried starting number 630.^[4][5] Driver Carlo Scagliarini and co-driver Luigi Garrone managed a 31st place at the finish (9th in class S1.1).^[2] It was also in the entry list as a "Sirca-Fiat" or "Abarth 205 Sirca" for the 1951 Mille Miglia. It was to be driven by Hermann Lothaller and Karl Anzenbacher and was issued number #231, but did not start the race.^[4]

Chassis 103

The most fully developed design, chassis number 103 is the second example built in spite of carrying the final chassis number. Unlike the first chassis, intended solely for competition, this was aimed at small series production for a wealthy clientele and was thus luxuriously appointed. This benefitted from a slight increase in the displacement of the Fiat 1100 engine from 1,089 to 1,188 cc (72.5 cu in), but with power reduced to 65 hp (48 kW) DIN thanks to a lower state of tune.

Its official presentation took place at the Turin Motor Show in May 1950. Curiously enough, the Michelotti-bodied Ferrari 166 Inter, presented in September 1950, was very similar, although larger in size, and marketed at about the same price. Both models were from the same designer and body shop, which did not favor the relationship between the two business leaders. The Ferrari's distinctly better performance meant that the 205A found no further takers.

Chassis 104 (Sport Ghia Coupé)

In 1953, the fourth 205A chassis (number 104) was completed with an eye-catching, airplane-inspired, bullet nosed design by Giovanni Michelotti, carrying Carrozzeria Ghia badges.^[6] The Abarth 1100 Sport Ghia Coupé, as it was called, received the mechanicals from the recently introduced Fiat 1100/103, with the engine tuned by Abarth to produce around 65 hp (48 kW). The car was shown at Turin in 1953 and at a few more European shows; it was then sold to Bill Vaughn, an American builder of fibreglass bodyshells. He showed it at the 1954 New York Auto Show as the "Vaughn SS Wildcat" and claimed that it was fitted with an overhead cam V8 engine. No Vaughn Wildcats were built and there is no evidence of the engine having been swapped.^[6] The car was not shown publicly again until 2015.
