Fiat Ritmo Bertone Supercabrio 100S Serie Tutta Bianca 1986 White Mitica 1:18

The Fiat Ritmo Bertone Supercabrio occupies a precise and often overlooked corner of Italian automotive history: a coachbuilt open-top car, designed and assembled by Bertone at its Grugliasco facility near Turin, sold through Fiat dealers from 1982 onward. The 100S variant, with its 1,498 cc inline-four producing around 105 hp, was the sportier option in the cabriolet lineup, capable of approximately 185 km/h. The Serie Tutta Bianca edition of 1986 took that already distinctive car and dressed it entirely in white — bodywork, soft-top, and interior alike.

A Bertone Creation, Not a Factory Convertible

The Ritmo Cabriolet was never a standard factory product in the conventional sense. Bertone engineered a reinforced floorpan derived from the Ritmo II platform (produced 1982–1988), then hand-finished each car at Grugliasco before delivery to Fiat's dealer network. This coachbuilding process placed the Supercabrio in a different category from mass-produced Italian convertibles of the period, and it means surviving examples are far rarer than the saloon and hatchback Ritmo variants produced in volume.

The Serie Tutta Bianca: A Study in Monochrome

Introduced circa 1985–1986, the Serie Tutta Bianca — literally the All-White Series — applied a single consistent colour treatment across every visible surface: body panels, soft-top hood, and interior upholstery. Where most Ritmo Cabriolets were finished in conventional colours or two-tone combinations, the Tutta Bianca presented a deliberate, style-led proposition aimed at design-conscious buyers. Because the cabriolet was already produced in smaller numbers than the standard Ritmo, any special-edition variant from this run represents a genuinely scarce survivor in the classic Italian car market today.

MITICA's 1:18 Resin Interpretation

MITICA is an Italian specialist manufacturer with a focus on historically significant Italian road cars that mainstream diecast producers routinely overlook. Working in resin, the Turin-based maker produces short-run 1:18 scale models where surface fidelity and colour accuracy take priority. This particular piece — the Supercabrio 100S in Serie Tutta Bianca — is listed as a Vroomi exclusive, meaning this specific colour and variant combination is not available through the general retail network. The model measures 22.0 cm in length, computed directly from the real car's 3,970 mm body.

In the Display Cabinet

At 22.0 cm long, the Supercabrio sits comfortably on a standard 1:18 shelf but benefits from a slightly wider footprint owing to the open soft-top profile. It pairs naturally with other Bertone-bodied Fiat subjects — the X1/9 is the obvious companion — or alongside MITICA's wider catalogue of rare Italian road cars from the 1980s. For collectors focused on Italian coachbuilding, the Tutta Bianca sits alongside Lancia and Alfa Romeo open-top pieces of the same era as a document of Turin's design culture at its most considered.
