The 430 was introduced in 1987 as part of Maserati’s Biturbo-derived sedan family, positioned above the smaller and more commonplace four-door models as a more powerful, more luxurious export-market offering. It arrived while Maserati was still building on the De Tomaso-era Biturbo formula: compact executive sizing, a turbocharged V6, and a blend of Italian style with a distinctly performance-oriented character. In Maserati’s own historical archive, the model is described as having been launched alongside the 425 and then taking over from it in 1989, marking the 430 as the evolution of the larger-sedan branch of that line rather than a clean-sheet redesign.
Visually and mechanically, the car remained closely tied to the broader Biturbo theme, but it was aimed at buyers who wanted a more refined and prestigious sedan with serious pace. The 430 used Maserati’s larger-displacement twin-turbo six and sat at the upper end of the brand’s saloon range during its run. In 1991, Maserati updated the model with four-valve cylinder heads, and the car was identified as the 430 4v to distinguish it from the continued three-valve version. Those later cars were part of the final stage of the Biturbo sedan story and reflected Maserati’s effort to keep the nameplate competitive through the early 1990s.
Production continued until 1994, with the nameplate representing one of the better-known and more desirable sedan derivatives of the Biturbo era. For enthusiasts, the 430 is significant as a bridge between the earlier, more compact Biturbo sedans and Maserati’s later attempts to refine its luxury-sport saloon formula. It stands out as a comparatively rare, high-spec four-door from a period when Maserati was rebuilding its road-car identity around turbocharged performance and classic Italian grand touring character.
