The Alfa Romeo 412 Spider Vignale

The Alfa Romeo 412 Spider Vignale was a racing car built in 1939 with a Touring body then changed in 1951 by Vignale who used a more modern and aerodynamic livery in line with Alfa Romeo style of that period. It took part in different races with the original body but also with the one made by Vignale.

One-off belonged to Felice Bonetto until 1953, it was sligthly modificated during the years for road use. 412 passed away in the early 1960s.

The car’s origins: the 12C-37 saved from the war

“I remember a itemized list of experimental racing cars existing at the Experience Service right after the war. It was the end of 1945.” In this way the memory about this car made by Elvira Ruocco, manager of the Alfa Romeo Historical Archive from 1983 to 2005, begins. She continues: “From this itemized list it appeared there were two 412 completed, (of 4 made), and one of them was located at the headquarter of Portello and anothe one was in another warehouse. Although I remember very well at the Triuggio decentralization a chassis complete with engine was in storage, another engine was storaged together with the 412 hospitalized in the Melzo decentralization.“

Its Story

The 412 was built in 1939 by Touring on the chassis of the 8C 2900A. Its engine is the 12-cylinder 4500, the same as the 12C of 1937. It had its debut on May 31, 1939 at the G.P. of Antwerp and it classified first and second thanks to the race drivers Giuseppe Farina and Raymond Sommer, and second at the G.P. of Luxembourg in 1939 thanks to Clemente Biondetti.

After the Second World War one of the four speciments produced (according to the book wrote by Fusi) was sold to the Swiss Willy Daetwyler, who led it to victory in different mountain races and in 1948, he won the G.P. of the Bremgarten.

The chassis shared with the 8C 2900-A was identified with the number 412151. Probably this number was used to named the car. It was equipped with a 12-cylinder V engine of 4495 cm3, built with two monoblocks 6 cylinders, which developed up to 430 hp and was turbocharged. It was designed by Vittorio Jano in 1937.

Therefore, the 412s derived from the 12C-37 single-seat, from which they inherited their engine. In 1936, the Grand Prix Alfa Romeos were called 12C-36s and they had an engine of 4,1 liter V12 and a similar, if not identical, car body to the 8C35 of 1935. In 1937 these cars were called 12C-37, and the engine was increased at 4,5 liters, but on a new and lower chassis.

On account of the subsequent limitation of the engine size for Gran Prix cars (3 liters), the 12 cylinders became useless, and were used since 1939 for sports-type races. With the Touring car body, the 412151 took part in different races, including the Mille Miglia of 1950 (Bonetto – Casnaghi) and the Targa Florio of 1950.

Carrozzeria Vignale

In 1951, the Alfa Romeo 412 of Felice Bonetto took part at the “Giro di Sicilia”, from 31 March to the first of April, but it off the road wrecking its car body. So, coachbuilder Vignale built a very light Spider as a second dress, deeply modifying the previous one. With this new car, at the end of April 1951, Bonetto  took part at the Mille Miglia ranking sixth with the number 427.

So, the intervention of Vignale can be dated to April 1951. This photography taken during the above mentioned Mille Miglia in which it’s not painted (maybe to reduce its weight for the race) and with the number 427 painted by hand. The car then participated in a race in Oporto in 1951, which it won  beating the Ferrari 166s and the Maserati’s.

Successive changes and use on the road

After the Mille Miglia of 1951 the car was modified. In Oporto we can see it painted, but other photos shows the car with further modifications.

On Road & Track magazine of October 1951 we can find an article called “A special 230 hp Alfa”, written by Corrado Millanta in which we can see other images of this car. In these photos we can see that the aerodynamic appendix placed behind the drivers head has been removed (which it was present during the Mille Miglia of the same year). It was designed to eliminate the aerodynamic turbulence caused by the driver’s head on account of the windscreen which was placed very low; moreover we can notice thin moldings surrounding the ‘volume’ in relief that comes from the shield, which runs through the hood reaching the ends of the windshield and up to the end of the car. The painting has a slight chromatic variation: the central part is slightly darker, giving the idea of a two-tone or a tone on tone body car. Comparing the other Alfa’s of that period, colors could be red with the central part dark red, red with the central part blue or red with the central part red blood, like the colors of the 6C 2500 Ala Spessa of 1939- 40.

The 412 Vignale is a pure two-seater Spider, characterized by a very long hood, 4 chromed air intakes for each side placed between the front fender and the cockpit. The front has 4 headlights, two at the ends and two central plus turn signals. Moreover it has the “scudetto”, appeared in a completed shape for the first time the year before (1950) on the 1900 sedan.

Unlike the 1900s, the shield has a very subtle vertical shape, recalling the design of the one of 6C 2500 Villa d’Este and other 6C 2500 made by Touring from 1946. As mentioned before, the shield is placed on a raised volume which continues along the entire bonnet up to the windshield, creating its basis in a very clear and marked way, as for the Villa d’Este, but here its smoother and without details/chrome, probably on account of the ‘essential’ character of this racing car. This is a beautiful Alfa Romeo which expresses a strong balance between great elegance and a sporting spirit. Its line is absolutely particular because it blends features of the Villa D’Este with others of the 1900 in a really unique way that we can’t see in other Alfa Romeo. Moreover the 12-cylinder engine equipped on this car increases enormously its appeal. Starting from the end of 1951 this car was also used on road (or maybe only forprivate use only, because it no longer took part in competitions and it was registered), as mentioned in another article appeared on Road & Track Magazine in September 1952, written by Burton Harrison. The journalist is accompanied on a breathtaking journey on the 412 driven by Bonetto, probably around the San Siro stadium in Milan. During the path of the car, an increasingly large crowd is witnessing the driver’s skills with growing enthusiasm. The 412 was parked at the Scuderia Volpini and its engine had just remade by Alfa Romeo, which had recommended not to exceed 5000 rpm. Although Bonetto was ‘in love’ with this car, it had already been put for sale, as confirmed also by an advertisement appeared on Road & Track Magazine in January 1953.

The death of Bonetto and the succession of sales

Felice Bonetto died on November 21, 1953 due to a racing accident, in Mexico, during the IV Carrera Panamericana. The 412 was sold to Cortese, who on 4/12/1954 offered it for 20 million lire to Henry Wessells, an American, well-known automobile collector, in particular of Alfa Romeo. In another letter of 12/1/1955 Cortese replied to Wessells that it  was no longer available because the car had been sold in Spain, but this step is not documented enough, and probably the car was sold to the Italian branch of a Spanish dealer.

The car was ‘saw again’ by Marc Wallach in Milan in 1958, who in 1999 wrote a letter to the editor of ‘Forza’ telling this episode, when he visited the last workshop of Enrico Nardi, in via Vincenzo Lancia in Turin. In that workshop he noticed 2 touring bodied cars with 6C 2500 engines and “a wonderful Alfa Romeo V12 GP 12C, with a 2-seat body from Vignale. There’s a photo taken in the workshop where we can see Wallach near the 412, identifiable by the rear air intake, placed between the cockpit and the rear fender.

The end of the 412

Probably Enrico Nardi kept the car as it is until 1960, a year that maybe marked the end of the 412. There are few sources about the last chapter of the history of this car and all referable to the history of Nardi and his activity, so they come from a single source and they aren’t verifiable, although no other source contradicts what is told in all publications about Nardi’s activity.

In 1960 the car was dismantled: chassis, engine and body were separated and had different fates. Part of the chassis was used to make a new car (read here our special): the Plymouth Silver Ray designed by Michelotti which remained a one-off.

It had a Plymouth engine, an eight-cylinder 320 hp. The news is also supported by a 1992 Nardi  calendar which shows it, specifying it was made on (or part of) an Alfa Romeo 4500 chassis.

The engine of the 412 remained for years in Nardi’s workshop until his daughter sold it in auction in 1998. It was bought by Larry Auriana, an American collector, who had it restored by Epifani Restorations, in Berkeley (USA). Probably he still owns it. The comment accompanying the engine at the auction is quite inaccurate but provides interesting news about the car.

There are no sources or news about the destiny of the car body of the 412 Vignale. The end of this beautiful, unique and engaging ‘dress’ is a mystery, although probably it didn’t survive, since there are no news about it.

Interesting facts

There’s at least one test of replication of the 412 Vignale, in red color. This is only an imitation with many inaccuracies compared to a photo of the original.

There are many scale models of this car which represent it both in the Mille Miglia race configuration and painted in different colors. Searching on internet we can find many photos of them, as further proof of the fact that 412 Vignale fascinated thousands of car enthusiasts, alfisti and not, from its birth to the present day.

Many years have passed since the last time in which the powerful and metallic sound of the 12-cylinder Alfa Romeo engine resounded on the streets of Milan and Italy, combined to the unique livery created by Vignale. Since then the Alfa has built the history of motoring in Italy and all over the World, marking it with its unique and admired brand, even if sometimes it experienced crises and dark times. The history of this car inserts itself into all stories of cars and men who making great this brand thanks to their passion, their tenacity and their Sports Heart.

I read about the replica which is currently for sale for around $350.000 !!!! This is crazy considering that it has the 6c engine. I would never pay for a replica that much money

Alfa Romeo TZ
Girardo & co

The Alfa Romeo TZ (Tubolare Zagato) is more than just a car: it is a landmark in the history of Italian automotive engineering and motorsport. This sleek, lightweight coupé marked Alfa Romeo’s return to racing in the 1960s, bridging the gap between the brand’s glorious pre-war racing heritage and its aspirations for modern motorsport dominance. Created in collaboration with Zagato and Auto Delta, the TZ became an icon of innovation, design, and competitive success.

The Foundations: A Record-Breaking Collaboration

In 1954, Alfa Romeo and Carlo Abarth began a historic partnership, facilitated by Mario Boano of Ghia. Their first project was a record-setting vehicle powered by Alfa Romeo’s 1900 engine, a precursor to the high-performance engineering that would define later models. While Boano left Ghia shortly thereafter, Abarth continued working with Alfa Romeo’s technical team at the Portello factory, setting the stage for further innovation.

In 1957, this partnership yielded the Abarth-Alfa Romeo 1100 Pininfarina Record, a car designed to dominate the “1100” engine category. Equipped with a tubular chassis, a lightweight aluminum body by Pininfarina, and a centrally positioned driver’s seat, this aerodynamic marvel achieved six speed records at Monza before suffering a dramatic crash due to a wheel failure. Though heavily damaged, the tubular chassis would later serve as the conceptual foundation for the Alfa Romeo TZ, demonstrating the enduring value of innovative experimentation.

Technical Highlights of the Alfa Romeo TZ

The first version of the Alfa Romeo TZ, often referred to as “TZ1” to distinguish it from its successor, the TZ2, represented a culmination of cutting-edge design and engineering. Developed under the direction of Orazio Satta Puliga and Giuseppe Busso at Alfa Romeo, the TZ was produced through a collaboration with Autodelta, SAI Ambrosini, and Zagato. Each partner brought unique expertise: Autodelta handled engine tuning and final assembly, SAI Ambrosini constructed the tubular steel chassis, and Zagato crafted the lightweight aerodynamic body—a conceptual evolution of the Giulietta SZ’s truncated tail design.

Girardo & co

The TZ was powered by Alfa Romeo’s 1.6-liter twin-cam engine, derived from the Giulia TI. In its road-going version, this engine produced 112 bhp (82 kW) at 6,500 rpm, thanks to dual Weber 45 DCOE carburetors. Competition versions, however, saw power outputs rise to an impressive 160 bhp (118 kW). To optimize cooling, the engine was tilted 15 degrees to the left, enhancing airflow around the cylinder head.

The tubular chassis was a masterpiece of engineering. Made of nickel-chromium steel, it weighed just 62 kilograms while maintaining exceptional rigidity. Paired with the proven mechanical components of the Giulia, including four-wheel disc brakes, magnesium alloy wheels, and fully independent suspension, the TZ achieved a featherweight of 660 kilograms. This remarkable weight reduction enabled a top speed exceeding 215 km/h in road trim, with race-prepped versions reaching approximately 240 km/h.

Aerodynamics played a pivotal role in the TZ’s performance. The car featured a truncated “Kammback” tail, a design influenced by Wunibald Kamm’s studies and tested concurrently by Zagato on Giulietta SZ prototypes. This innovative shape reduced drag while maintaining stability, making the TZ a benchmark in aerodynamic efficiency.

Racing Debut and Early Triumphs

The TZ made its competitive debut in November 1963 at the Tour de Corse. Although both cars entered retired due to an accident and a suspension failure, success came swiftly. On November 24, 1963, at the Autodromo di Monza during a race organized by FISA, the TZ claimed a resounding victory, taking the top four spots in the prototype category. Lorenzo Bandini, Giampiero Bussinello, Giancarlo Baghetti, and Consalvo Sanesi led the charge.

Following its homologation in the Sport 1600 category, the TZ became a dominant force in both European and North American competitions. Between 1963 and 1965, 112 examples were produced, cementing the TZ’s legacy as a versatile and formidable competitor on road and track.

Legacy and Evolution: The TZ Line and Beyond

The Alfa Romeo TZ holds a significant place in the history of motorsport, not only for its innovative design and competition success but also as a milestone in the evolution of Alfa Romeo’s racing ambitions. The project benefited from the expertise of Carlo Chiti, a brilliant engineer whose career included stints at Ferrari and A.T.S. before co-founding “Auto-Delta” in 1963 with Lodovico Chizzola. Auto-Delta, established in Udine near Gianni Chizzola’s Alfa Romeo dealership, acted as a front for Alfa Romeo’s semi-official racing activities, allowing the brand to re-enter the motorsport scene without making an overt corporate commitment.

Alfa Romeo TZ

By late 1965, Auto-Delta transitioned into Autodelta, Alfa Romeo’s official racing department, and relocated to Settimo Milanese. During this period, a total of 106 examples of the TZ were completed, although the original numbering scheme (750 001 to 750 108) included anomalies. For instance, chassis 750 101 was used for the Bertone-designed Alfa Romeo Canguro rather than a TZ, and some chassis, such as 750 000 (a spider prototype), remain controversial. Additionally, several cars were later modified into TZ2 specifications, including chassis 750 004, 750 072, and 750 079, following damage or repurposing.

Famous Chassis and Racing Success

The TZ enjoyed a decorated racing career. Notable examples include:

750 006, which competed at the 1964 24 Hours of Le Mans, driven by Biscaldi and Sala, and is immortalized in a famous photo exiting the Mulsanne curve.

750 011, victorious in its class at the 1965 Targa Florio, driven by Bussinello and Deserti.

750 015, piloted by Frenchman Jean Rolland to the French Gran Turismo Championship in 1964, continuing to compete until 1966.

750 025, driven by Lorenzo Bandini at the Coppa FISA in Monza.

The TZ2, TZ3 Corsa, and TZ3 Stradale

The TZ2, introduced in 1965, represented a more advanced iteration of the original TZ. With a sleeker fiberglass body and enhanced aerodynamics, the TZ2 was even lighter and faster, designed exclusively for racing.

Decades later, Zagato revived the TZ lineage with the TZ3 Corsa and TZ3 Stradale, paying homage to the original models. The TZ3 Corsa, unveiled in 2010, was a one-off racing car powered by an Alfa Romeo engine. The TZ3 Stradale followed, blending Italian design with American power in a road-legal car based on the Dodge Viper ACR platform.

A Collector’s Puzzle and Enduring Legacy

The TZ’s rich history is further complicated by issues of chassis identification and authenticity. Several chassis bear double numbers, while others are suspected replicas. Despite these mysteries, the TZ remains a prized collector’s item, symbolizing Alfa Romeo’s ingenuity and competitive spirit.

From the groundbreaking TZ1 to the futuristic TZ3, the Tubolare Zagato series encapsulates Alfa Romeo’s commitment to innovation, design, and performance—a legacy that continues to inspire the world of motorsport and beyond.
