At the beginning of 2009 the museum was closed down a first time for renovations and opened in the end of the year, to celebrate Alfa Romeo's 100th birthday in 2010.

[2] The museum is dedicated to over 100 years of history of the Alfa Romeo marque, whose production included automobiles, commercial vehicles, railway locomotives, tractors, buses, trams, marine and aircraft engines.

On February 3, 1982, the journalist Luca Grandori, together with Edilberto Mandelli, Pietro Rondo, Giorgio Schoen, Stefano Senin and Renato Ughi, founded the Scuderia in Arese as part of the Centro Direzionale Alfa Romeo with the patronage of the mother company.

In 1990 Scuderia del Portello changed its statute and broadened its activity to also include modern racing cars, becoming an official club of the communication of the brand management.

The Scuderia took part in the commemorations of important historical races such as the Carrera Panamericana (1990, 1991, 2002), where in 1991 it was awarded “best participating team”, and in 2002 won in the Sport Menor category with Arturo Merzario and Vinicio Marta (Alfa Romeo Giulietta Spider Veloce), and in the Original Panamericana category with Prisca Taruffi and Antonio Maglione (Alfa Romeo Giulietta Sprint Veloce).

In Italy, Scuderia del Portello members and cars usually participate in commemorations of the historical Mille Miglia and Targa Florio.
