Alfa Romeo Giulia TZ Stradale

The Alfa Romeo Giulia TZ (Tubolare Zagato) was a sports car and racing car manufactured by Alfa Romeo from 1963 to 1967. The original TZ, currently sometimes referenced as TZ1 to differ from later TZ2, was developed together with Autodelta. It featured a 1,570 cc twin cam engine and other mechanical components shared with the Alfa Romeo Giulia and carried a 105 series chassis number, but was a purpose built sports racing car, with a tubular spaceframe chassis, light all-aluminium bodywork, disc brakes and independent suspension. The result was a lightweight coupé of only 660 kilograms (1,452 lb) and top speed of 134 miles per hour (216 km/h). The TZ was built both for street and racing trim, with the latest racing versions producing up to 160 brake horsepower (120 kW). Alfa's twin-spark cylinder head, as also used in the GTA, contributed to the speed of the TZ; the standard Giulia alloy block with wet steel liners was installed at an angle under the hood of the TZ to improve airflow.
