Seja como for, não deixa de ser um belo carro e mais um clássico obrigatório em qualquer colecção de slot.

Pequena História do Alfa Tz:
Autodelta was responsible for all of Alfa Romeo's race development, and in 1964 it redesigned the successful Alfa Romeo TZ1 into a more powerful machine, creating what many have called a 'mini Ferrari GTO' - the TZ2. The main difference between the cars was the use of fiberglass, and despite the fact that most cars were built from the same moulds, many differed in detail. The TZ2 has Alfa's 4-cylinder, 1600cc engine with hotter camshafts, larger valves and twin-plug ignition, producing 170bhp at 7500 RPM, which was good for 160 MPH! This early TZ2 (chassis number AR750106) won its class at Monza, Sebring, and the Nurburgring during 1965 and 1966. It is completely original, never having been crashed, and it has never been restored.
Ing. Carlo Chiti was in charge of Autodelta during the creation of the Alfa Romeo TZ2 project. His resume included being former Chief Engineer at Ferrari. It is understandable that the inspiration and passion of the Ferrari 250 GTO bled into this project. The TZ2 (Tubolare Zagato) was constructed as a works car and there were no intentions of providing any examples to privateers. They were intended to challenge the GT category. In total, there were, at most, fourteen constructed.
The chassis was from the original TZ, consisting of steel-tubed space-frame construction. Improvements were made to the original unit, with the TZ2 having lower suspension mounts and being more adjustable. The prototype car was given an all-alloy bodyshell designed by Ercole Spada for Zagato. The subsequent cars were molded from this and built with glassfibre. The total height of the vehicle was just a mere 41-inches. The aerodynamic design defied wind while maintaining an elegant stance.
Under the bonnet lay an Alfa Romeo dual overhead camshaft four-cylinder engine displacing 1570cc. The engines were tuned by Virgilio Conrero's Torino shop, Autotecnica Conrero. They were given larger valves, magnesium casings, upgraded camshafts, two side-draught Weber carburetors, dry sump lubrication, and a twin plug head. These improvements brought the horsepower to 170 and top speed in the neighborhood of 160 mph.
The cars made their debut at the 1965 Geneva Salon and production lasted until mid-1967. Some of the TZ2's were upgraded TZ's. Coachwork was handled mostly by Zagato. Chassis number 114, created in 1966, was done by Pininfarina. Another example, chassis 101, was done by Bertone. Bertone's example was done to test the feasibility of creating a road-going version. It was built atop a tubular steel space-frame and given Campagnolo 13-inch forged magnesium wheels. The body was very curvy. At the front were covered headlights and a wrap-around windshield. The body was constructed mostly from aluminum. The engine was from a Alfa Romeo TZ, producing 130 horsepower in standard guise.
The Bertone example made its debut at the 1964 Paris Salon. There was much interest in the car, but Alfa Romeo decided to abandon the idea. A journalist later damaged the car while doing a test drive. Most everything was able to be salvaged.
The racing debut of the Alfa Romeo TZ2 was at the 1965 24 Hours of LeMans. There were three TZ2 models entered, and all three failed to finish the race. This would be their only outing for the season. In 1966, they re-appeared, and in very strong fashion. In each of the 1.6-liter GT races they entered, they emerged victorious.
Even with this new-found racing success of the TZ2, the program was dropped and efforts were reverted to the GTA and Tipo 33 program. Most of the TZ2 cars were later sold to privateers.
