The original TZ, currently sometimes referenced as TZ1 to differ from later TZ2, was developed in together with Autodelta, a company led by Ex-Ferrari engineer Carlo Chiti. It featured a 1570 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 650 kilograms (1,400 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.
