Maserati
A6GCS (1947-1950)

Why it matters

The last car designed under the Maserati brothers Ernesto, Ettore and Bindo, with Alberto Massimino as their designated successor. It broke with earlier Maserati practice by dropping the supercharger for a naturally aspirated engine with a single overhead camshaft.

Production

Every figure says what it counts.

Independent counts (e.g. engine and colour) are never combined into a calculated figure. Surviving examples are never presented as original production.

History

The A6GCS name stands for Alfieri (Maserati), 6 cylinders, Ghisa (cast iron), Corsa Sport. The first cars had open barchetta bodies by Fantuzzi with motorcycle-style wings and a single central headlight, and in 1948 a version with enclosed wings and three headlights was introduced for endurance racing. A single aerodynamic coupé was built for Villoresi for the 1947 Mille Miglia. Two works cars ran in 1947-48 with Alberto Ascari and Luigi Villoresi, Villoresi winning the Italian championship both years. 15 cars were built in total, two exported to Brazil and one to the United States. From 1950 a twin-cam engine was tried on two of the competition cars.
