Video: Zagato shows off new Alfa Romeo TZ3 Stradale

Article by Christian Andrei, on May 1, 2011

Alfa Romeo marks its 2010 centennial celebration with the Zagato "TZ3 program" that ultimately results in the delivery of the TZ3 Stradale.

The program started in 2009 with the TZ3 Corsa, a non-production car which was bestowed with the 2010 Villa D’Este Design Concept Award. The nine TZ3 Stradale units came after this model.

Two programs were created with a common tribute.

The TZ3 Corsa is a neo-classic built for track racing and cannot be considered a design concept. TZ3 Stradale is an avant-garde design exercise car which is not made for racing.

The TZ3 Corsa, a non-production one-off, pays homage to the Alfa Romeo and Zagato racing heritage. TZ3 Stradale honours the Alfa Romeo and Zagato street legal heritage. Only 9 units were built.

In all, there are 10 collectible cars commemorating Alfa Romeo’s 100th anniversary constructed by their most frequent design partner, and having racing and road legal bodies.

The TZ3 Corsa is a tribute to the men and racing cars in the heritage of Alfa Romeo Zagato:

• Scuderia Ferrari (of the 1920s and 30s)

• Alfa Corse (1940s and 50s)

• Autodelta (1960s and 70s)

• Scuderia Zagato (1980s and 90s)

The TZ3 Stradale commemorates the road coupé heritage of Alfa Romeo Zagato:

• RLSS, 1500, 1750, 2300 and 2900 Zagato (1920s and 30s)

• Giulietta SVZ, 1900 SSZ and 6C 2500 Panoramica (1940s and 50s)

• Giulia TZ, Junior Z, SZ and 2600 SZ (1960s and 70s)

• R.Z. and S.Z. (1980s and 90s)

The TZ3 Corsa has a mono shell carbon fibre chassis, a tubular frame and a hand-beaten lightweight aluminium body shell. Its front-central engine is a V8 90° 4.2 litre type and it has a 6-speed sequential gearbox.

The TZ3 Stradale uses the Viper ACR mechanical chassis and a carbon fibre body. "Bellezza necessaria" is its motto. It can be counted as the first American Alfa Romeo because it is the company’s first car to match the USA power train.

The TZ3 Corsa falls in line with Zagato’s gentlemen-driver tradition, and was ordered for Martin Knapp, an Alfa Romeo and Zagato collector. Meanwhile, the first delivery of the TZ3 Stradale was to Eric King, an American Alfa Romeo and Zagato collector who also sits on the board of the Saratoga Automobile Museum. The second and third deliveries will be to Japan and Europe, respectively.

Both the Corsa and the Stradale have a typical Kamm-tail (K-tail) configuration. This layout originated in the ‘60s in Italy with Zagato’s testing of the “Coda Tronca,” and has become widely recognised since, especially after its use on the Alfa Romeo TZ and TZ2.

The Kamm Effect is the result of a particular vehicle design form that greatly improves it aerodynamically.

Because of this, the lowering the CX is possible with the same compact volumes. The Kamm Tail design results in a significant decrease in wind resistance. Thus, the stretched teardrop tail shape is not necessary anymore.

Press Release

Zagato TZ3 Stradale

The "TZ3 program" managed by Zagato to celebrate the 100th Anniversary of Alfa Romeo (1910-2010) ends with the delivery of the TZ3 Stradale.

The initiative started in 2009 with the manufacturing of the "one off" TZ3 Corsa which won the Villa D'Este Design Concept Award in 2010 and followed with nine (9) TZ3 Stradale.

Two different approaches for the same tribute.

The TZ3 Corsa is a track car. It is not a design exercise. It is a Neo-Classic car.
The TZ3 Stradale is a Design Exercise. It is not a race car. It is an Avant-garde car.
The TZ3 Corsa is a tribute to the Alfa Romeo and Zagato racing heritage. It is a one off.
The TZ3 Stradale is a tribute to the Alfa Romeo and Zagato street legal heritage. Just 9 examples in the world.

In total 10 collectible cars for the 100th anniversary of Alfa Romeo made by its most prolific contributor, both with race and road legal bodies.

The TZ3 Corsa celebrates men and machines of the Alfa Romeo Zagato racing heritage:
• Scuderia Ferrari (20s and 30s)
• Alfa Corse (40s and 50s)
• Autodelta (60s and 70s)
• Scuderia Zagato (80s and 90s)

The TZ3 Stradale celebrates the road legal heritage of Alfa Romeo Zagato coupés:
• RLSS, 1500, 1750, 2300 and 2900 Zagato (20s and 30s)
• 6C 2500 Panoramica, 1900 SSZ and the Giulietta SVZ (40s and 50s)
• SZ, 2600 SZ, Giulia TZ and Junior Z (60s and 70s)
• S.Z. and R.Z. (80s and 90s)

The TZ3 Corsa is based on a mono shell carbon fibre chassis, coupled with a tubular frame and a handbeaten lightweight aluminium body. It's equipped with a front-central V8 90° 4.2 litres engine and 6-speed sequential gearbox.

The TZ3 Stradale is based on the Viper ACR mechanical chassis with a carbon fibre body. "Bellezza necessaria" is the inspiration of this car which matches for the first time an USA power train and can represent the first American Alfa Romeo.

Following Zagato's gentlemen-driver heritage, TZ3 Corsa has been commissioned by the Alfa Romeo Zagato collector Martin Kapp. The first TZ3 Stradale has been delivered to the US Alfa Romeo and Zagato collector (and Saratoga Automobile Museum's board member) Eric King. The TZ3 Stradale n°2 and n°3 will be delivered in Japan and Europe.

Both TZ3 Corsa and TZ3 Stradale boast a typical Kamm-tail (K-tail) layout. This solution became famous in Italy with the "Coda Tronca" bodies which were tested by Zagato in the beginning of
the 60s. They reached their apex on the Alfa Romeo TZ and TZ2.

Kamm Effect is part of the functional design approach that aims to the aerodynamic efficiency.

According to this, the CX can be lowered by keeping compact volumes at the same time. The reduction of the wind resistance is assured with the Kamm Tail design, without any need of a very stretched "drop" shape of the tail.
