Stanguellini Colibrì History

In 1963, with Formula Junior production winding down, Vittorio Stanguellini turned his attention to land-speed records. The Colibrì (Italian for hummingbird) was a one-off single-seat streamliner powered by a 250 cc Moto Guzzi motorcycle racing engine. The enclosed body was designed by Franco Scaglione, best known for his Alfa Romeo Bertone studies, and emphasised absolute aerodynamic efficiency at very low power outputs.

At the Autodromo Nazionale di Monza in 1963, the Colibrì set six FIA international speed records in its 250 cc class. The project demonstrated that Stanguellini's obsession with lightness and precision engineering extended beyond conventional racing categories — the same principles that had made the barchettas and Formula Juniors competitive were applied to extracting maximum velocity from a quarter-litre engine.
