Staying true to his determination to build the “pur sang of automobiles”, Ettore, when restarting the activity of his factory in 1919, resumed the project of an 8-cylinder engine, which would allow him to access the market of luxury cars.

Thus, the Type 28 presented in 1921, was a prototype equipped with a 3-liter engine, which resulted from the union of two 4 cylinders blocks, with 3 valves per cylinder. The paralepipedic form of the engine, as well as the mechanical structure would remain in the brand's models until the presentation of the Type 50.

Exhibited at the Paris, London and Nice Motor Shows of that same year, this model never went into production , for lack of financial means for such an expensive operation. This prototype would, however, give rise to the Type 44 a few years later.

The experience acquired with the Type 28, continued, in 1922, with the construction of the competition Type 30, equipped with a 2-liter engine, the maximum permitted displacement, derived from the 3-liter block of the Type 28 prototype. This competition Type 30 model used a “Brescia” chassis equipped with an aerodynamic bodywork, with a fusiform shape.

Four models of this car were built, in order to participate in the French GP, disputed in the urban circuit of Strasbourg. Despite systematic problems with the brakes, the Bugatti secured 2nd and 3rd places, behind the Fiat de Nazzaro. Another 5 of these vehicles, equipped with “conventional” bodies, were registered, by private drivers, in the Indianapolis 500 race of the following year, in a participation that ended without success.

The new Type 30 road car was introduced in 1923, being the first standard Bugatti to be powered with an 8-cylinder engine.
