Alfa Romeo’s Bertone-styled Giulietta Sprint debuted in April 1954, powered by a 1.3-liter, all-alloy, twin-cam, four-cylinder engine designed by former Ferrari engineer Giuseppe Busso. The model was an instant success, and to meet demand for a high-performance version, the sporting Veloce model was introduced for 1956. For those seeking even more outright speed and race-winning capability, an alleggerita (lightweight) variant was offered. These purpose-built machines were about 150 pounds lighter than the standard model, thanks to their aluminum doors, hood, trunk lid, bumpers, headlight bezels, simplified interior, and Plexiglas windows.

According to Alfa Romeo Centro Storico, this Sprint Veloce Alleggerita, chassis 01871, was manufactured on May 26, 1956, finished in Rosso Alfa (Alfa Red), and equipped with engine no. 30043. Among the first 50 examples constructed based on its Bertone body number (77043), this Giulietta was originally delivered to General Automobile Paris and reportedly prepared for competition use by the legendary Torino-based tuner Virgilio Conrero.

Throughout 1956, the Alleggerita was campaigned by Écurie de Paris-Île de France, a racing team whose roster of drivers included Michel Nicol, Jean Martin, and Roger de Lageneste, the grandson of Jean-Pierre Peugeot. Highlights from the racing season include a 10th Place finish in the grueling Tour de France and 4th Place in the Tour de Corse.

In August 1964, following its active racing career, the Giulietta was sold to Gerard Goldbronn of Colmar, France, who retained it for two decades before selling it to Swiss Alfa Romeo collector Willy Aeppli in September 1984. A complete restoration ensued and, after completion in 1988, the Alfa Romeo participated in club events, hill climbs, and historic races including the Buchenegg Grand Prix. In 2011, Kurt Hasler of Bonstetten, Switzerland, acquired the Giulietta and commissioned marque specialist Oliver Vetter to carry out a thorough mechanical overhaul that included rebuilding the engine and gearbox. Ken Roath then imported the Alleggerita into the US and, together with his SZ and TZ, it has formed the ideal trio of lightweight Alfa Romeo GT machines.

Accompanying the sale is an impressive history file that includes a FIVA Identity Card (dated 2011), copies of period photos, correspondence with Alfa Romeo Centro Storico, European registration records, service invoices, articles, and even a book produced by Kurt Hasler that details this car’s remarkable history.

With its matching-numbers engine and rich, period racing history, this Sprint Veloce Alleggerita ranks among the finest surviving examples of a rare and historically significant Alfa Romeo competition car.
