Making a car that is both beautiful and fast is no easy task. It takes talent, financial means and a great deal of skill. Gino and Oscar Jankovits, Alfa Romeo dealers in the Croatian city of Rijeka, used all three in the construction of their Aerospider, mixed with an unsolved mystery regarding the origins of their project. We will attempt to shed some light on the matter: the chassis is by Alfa Romeo and it has a very specific number: 700316 and the car was designed to mount a 12-cylinder engine at the rear, again by Alfa Romeo. 

No document has been able to prove that the Jankovits Aerospider was a direct collaboration with Alfa Romeo, but its technical layout, including the central driving position, 12-cylinder engine and racing car weight distribution corroborates the theory of a direct involvement of the Milanese company

However, the car was powered by a six cylinder engine with three dual Weber 36 D 04 carburettors. The period was 1934 and 1935 when the Auto Union Grand Prix cars were leaving their mark on racing circuits around the world, in particular the Type A, 16-cylinder rear engine version. At Alfa Romeo, technical genius Vittorio Jano was developing a V12 engine in an attempt to weaken the German’s unwavering power in the Grand Prix with the front-engined Mercedes, and the new rear-engined Auto Union rivals. This makes it quite plausible that Jano entered a confidential agreement with the trusted dealer from Fiume (and consequently far from Milan) to build a rear-engined sports car, and to experiment with the new engine.

The closed body gives makes the car appear very long due to its rear mid-mounted engine. Imagining it as a single seater bestows it with far more normal proportions

The arrival of the engineer Wilfredo Ricart in Alfa Romeo who changed tact and started the Type 512 project (which never raced) may have been the cause of the failure to supply the Jankovits brothers with the 12-cylinder engine which, in turn, forced them to user the 6-cylinder version. This hypothesis is also confirmed by the dates of construction: built in 1935 the car took to the streets only in 1939 and makes the theory all the more credible. The type 512, in fact, was born that very same year even though it was dated 1940.

The nose shows just how much the style of the car was determined by maximum aerodynamic efficiency. Note the small central windshield intended to protect the driver

Beyond its history, the Aerospider is now in Germany In the hands of a passionate collector, and retains much of the innovative spirit of its period. With its central-driving position (which says a lot about its vocation for single-seater experimentation), it mounts the engine “inboard” and presents a clean and remarkably modern line.

A chapter that cannot be ignored in our story.

Built in 1934 and first registered in 1939, the Jankovits Aerospider survived the war and today belongs to a German collector
