Alfa Romeo TZ

TZ1

Alfa Romeo Giulia TZ1

The TZ 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-aluminum bodywork, disc brakes and independent suspension. The result was a lightweight coupé of only 650 kg and top speed of 134mph.The TZ was built both for street and racing trim, with the latest racing versions producing up to 160bhp. 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.

Aiding the TZ in its quest for performance was the treatment of the rear bodywork. Incorporating the research of Dr. Wunibald Kamm, the TZ used a style called "coda tronca" in Italian, meaning "short tail.", otherwise known as the Kamm tail. The principle is that unless you are willing to incorporate an aircraft-like extended tail (not practical for an automobile), there is surprisingly little increase in drag by simply chopping the tail at an angle. Zagato had previously proved the success of this tail treatment in their "coda tronca" Sprint Zagato sports-racing cars, and it was a natural evolution to adapt this to the Giulia TZ.

The car debuted at the 1963 FISA Monza Cup, where TZs took the first four places in the prototype category. At the beginning of 1964 the TZ was homologated (100 units were needed for homologation) to the Gran Turismo category. After homologation it started to take more class wins in Europe and North-America. Of the first TZ, 112 units were built between 1963 and 1965.

Some automobiles generate strong feelings and emotions, close to love, because what is at stake does not relate to reason or to common sense. The Alfa-Romeo TZ2, more than scarce, so rare in effect that most enthusiasts have never seen one in their hole life, still lives intensely in the imaginary realm of fine racing automobiles, but also in the reality.

Of course, its incredible beauty seizes us first of all: this fusion between its relentless effectiveness and a kind of magnetic sensuality irradiates something obscure and irresistible.

We know that this car is almost too low, waiting to leap from the ground like a feline, that the best pencils of the 20th century, Elio Zagato and Ercole Spada, conceived in a state of grace, that its tubular frame, its glass fiber dress, its dual ignition engine, each part of it is above all and only intended for racing, and for battles without mercy – the TZ2 almost always won...

But its mystery, the mystic of the TZ2 remains intact. We also know that each cubic centimeter of this car was born from the talent and the work of the engineers Chiti, Chizzola, and other enthusiast masters of the Autodelta legend. But this car always strikes us first by its beautiful body, almost crushed on its four wheels, by its oval and timeless aerodynamically covered headlights, its free exhaust emerging from the sides, "la beauté du diable" TZ2 all of which will remain for us the mark of its identity.

Is it because its official racing life was very short; listing of the TZ2’s victories is carved in the legend: this car simply won, in its class, all the races in which it took part in 1966: Sebring, Monza, Targa Florio, [Nurburgring], Mugello, Enna.

The TZ2 was the state-of-the-art, period. This all in a time when competition was a matter of technical geniuses! Talented engineers, passionate technicians and drivers, and where computers and marketing quite simply did not exist, it came as a definitive masterwork. Ultra light, collected and concise like the very best race cars of the period, it was conceived and built only for the Alfa Works Team (contrary to the TZ1, meant to be sold to privateers) and was driven to victory which was its irresistible destiny. The very first TZ2 ever built, was painted in bright orange.

Administrative follow-up, almost non-existent at Autodelta in this period - focused on race results - , does not allow to establish the exact number of the few TZ2 that ever existed. Chassis numbers go in theory from 104 to 117, but at least half were modified TZ1 frames, others were destroyed or damaged. And finally all were sold, in parts or complete, to privateers by Autodelta.

The TZ2 differ from one to the other by various parts and body details, and incorporate some elements from the TZ1. The few still in existence are now out of reach and stay either in museums or are not affordable: the last auctioned TZ2 changed hands for approximately 820.000€, another was recently estimated at 1,65 M€ but didn't sell.

Some TZ2s were more or less damaged during races or practices, and a few have been reconstructed. The refabrication of period parts, in the true and authentic spirit of the period is indeed possible and even necessary to give back life to these wonders. Thus, the possibility of acquiring such a legendary car, incorporating period elements in conformity and restored or manufactured according to correct specifications, with the advice and guidance of the most qualified specialists, is a rare event.

The memorable and splendid double-cam Alfa-Romeo GTA straight-four, fitted with the correct dual ignition head, finds its place in the tubular frame equipped with the areodynamic body created at Autodelta in 1965. This is a car which exsudes history and memories, at first glance. It will make it possible to the owner of this jewel to dominate the situation in most competitions reserved for the historical vehicles.

Alfa Romeo TZ Prototype

In response to Alfa Romeo's request for a TZ successor, Autodelta's co-founder Lodovico Chizzola built this prototype, only for Alfa Romeo to opt for its own design - the TZ2 - so the car remained a one-off. After completion this unique Alfa Romeo remained the Chizzola family's property until it was bought by the current vendor at Bonhams' Nürburgring Sale in August 2000 (Lot 112). Known in the Chizzola family as the 'TZ1½', the car is a development of the original TZ. The un-numbered chassis is a one-of-a-kind tubular design - a modified Ferrari F2 frame according to the late Lodovico Chizzola - but shorter and different to a TZ's. The glassfibre 'gull-wing' coachwork is of an unusual design that corresponds to a scale model kept at the Alfa Romeo Centrostile museum. Both side and rear windows are of Plexiglas, and the cockpit features a wide transmission tunnel, the familiar TZ wood-rim steering wheel and TZ/Giulia gearlever knob, switches, etc.

The car has a genuine TZ-type 'single-plug' engine, the latter breathing through twin Weber 45DCOE carburettors, and runs on 13" diameter alloy wheels (à la TZ2). The engine is set low and well back in the chassis while the wheels are positioned at the extreme corners, thus achieving minimal body overhangs. The leading TZ2-owning authority acquainted with this car since new says that it drives very much like a TZ2.

This unique TZ prototype has covered only a minimal distance since completion, but Lodovico Chizzola's sister recalled one memorable drive with her brother over the standard test route along which he drove all TZs prior to delivery. Comprising 80 kilometers of twisty mountain roads, it typically takes 1½ hours but was covered in this car in just 40 minutes! Stored at the old Autodelta works, 1965-2000, the car had only been seen in public once prior to its sale in 2000, at the 1996 Autodelta Reunion at Udine where it was the star of the event. Source
