1964 Alfa Romeo Giulia TZ-1 'Double Bubble'

The 1964 Alfa Romeo Giulia TZ-1 is one of the most celebrated racing cars ever produced by Alfa Romeo. Developed in collaboration with Carrozzeria Zagato, the TZ-1 featured an ultra-lightweight aluminum body and the distinctive "Double Bubble" roof design, which improved aerodynamics while providing additional headroom for helmeted drivers. Powered by a lively 1.6-litre twin-cam engine and weighing less than 700 kg, the TZ-1 achieved remarkable success in GT racing throughout the 1960s. Today, it remains one of the rarest and most desirable Alfa Romeos, admired for its elegant styling, racing pedigree and engineering innovation.
