Since then, the company has been run by his son Francesco and offers service for the restoration, maintenance and operation of historic racing cars.

[2] A passionate racer, Stanguellini began tuning and modifying Alfa Romeo, Fiat and Maserati cars for racing.

Despite being a competitor, he developed a friendly rivalry with Enzo Ferrari in the late 1920s, the latter seeing the presence of Stanguellini as a potential reinforcement for the racing cars scene in Modena.

The cars were conspicuous for being elegantly engineered, with light-alloy cylinder blocks, twin overhead camshafts (bialbero) and dual side-draught Weber carburettors.

[3] The engine proved to be successful and Stanguellini racing cars went on to win numerous national championships in Italy and France.

[5] In 1963, Stanguellini completed a single-seat streamliner called the "Colibrì" (Italian for hummingbird), powered by a 250 cc Moto Guzzi motorcycle racing engine.

"[1] Walt Hansgen won the FJ race at the inaugural United States Grand Prix meeting at Sebring, Florida, on 12 December 1959, driving a Stanguellini.

[8] After 1966, the Stanguellini family concentrated their efforts on tuning equipment and subcontract design,[2] while also running their Modena Fiat dealership.
