Sergio Sartorelli: Designer of Dreams

The early years

Designer Sergio Sartorelli was born in Alessandria in 1928; he took the degree in Mechanical Engineering at the “Politecnico” of Turin and soon became interested in cars. He developed a passion and interest for everything that moved on wheels, including cars, trucks, trains, and even military vehicles. The dark periods of the 40s led him to draw vehicles on school books. He also builds wooden models in scale by copying the shapes from war magazines of that time.

With his engineering studies at the Politecnico of Turin, his design skills began to improve from a technical point of view, and his drawings became more and more realistic. In 1954, he graduated in Mechanical Engineering and completed the Military Service in Turin as a cartographer at the North West High Command.

In an 18 months period, he managed to carve out some time. In a small room, he develops car sketches which he presents to the Boano Coachbuilder, obtaining the task of developing others based on drawing. In the same period, he developed some advertising truck proposals for the Pasino coachbuilder in Alessandria. After the military service in April 1956 and getting a negative response from the Boano Coachbuilder and Pinin Farina, Sergio tried his luck at GhiaMonviso. Ghia, looking for a larger production plan, bought Monviso in 1954. Designer Sergio Sartorelli presented his handmade photos and sketches and was immediately hired by Eng. Segre and by the CEO Mr. Casalis.

His activity at Ghia

Designer Sergio Sartorelli ‘s activity in Ghia began in 1957 under the guidance of Eng. Savonuzzi. He started the apprenticeship with airbrush sketches; he designed a proposal for Volkswagen 1200 Beetle prototype, Coupé, Spider, and Giardinetta based on the Fiat 1100 TV chassis, which were unveiled at the 1957 Turin Motor Show among the beach version called Jolly based on the Fiat 500, 600 (both produced in small series) and the one-off 1100. At the end of 1957, when Eng. Savonuzzi left Ghia for Chrysler, and Sergio became “Head of the Prototype Department.”

One of his first projects was the Chrysler 375 unveiled with the brand Dual-Ghia, followed by several prototypes, including the Ghia Selene designed in collaboration with Tom Tjaarda, the restyling of the Karmann Ghia, and the mysterious Warzawa, built as sedan and wagon. At the turn of those years, radical transformations took place regarding the headquarters of Ghia. The old Ghia-Monviso headquarters was no longer sufficient, so a new headquarters was built in 1958 in Via Agostino da Montefeltro, much larger and more modern. Finally, in 1959, a new factory began in front of the new Ghia headquarters to renovate an old ammunition factory.

Officine Stampaggi Industriali

So the new Ghia-Osi company (Officine Stampaggi Industriali) was born on the initiative of Eng. Segre and Avv. Arrigo Olivetti, owner of FERGAT. The initiative of Eng. Segre was courageous and far-sighted: to equip Ghia with a parallel structure, capable of producing small special series for the large car industry, but without renouncing to maintain its research and design atelier and it should keep separate the two departments. The following years were marked by high productivity by Carrozzeria Ghia, Sergio Sartorelli designed several models, from the less known prototypes of the Alfa Romeo Giulietta Sprint to a special hunting car based on the Chrysler 30 M for the King of Kuwait and the more famous one-off and production models such as the Fiat 2300 S Coupé, Cabriolet, and Wagon version and the Maserati 5000 GT made for Innocenti. Sartorelli’s adventure as a Ghia employee ended in 1963 with the Ford Falcon Clan prototype and the Chrysler Imperial Crown restyling.

The Maserati 5000 GT one-off by Ghia designed by Sergio Sartorelli

With the death of Segre in February 1963, the Ghia-Osi pact was abruptly interrupted, and Sartorelli worked for Ghia as an external collaborator. At that time, OSI mass-produced the Fiat 2300 S coupé and the Fiat “Familiare” 1300/1500.

Suddenly lacking a Centro Stile, it temporarily availed itself of the external collaboration of the stylist Michelotti. In 1965, with the arrival in Osi of Eng. Giacomo Bianco, the Osi Style Center, was born in a new building near Turin with a large warehouse equipped for the execution of prototypes next to it, complete with a small wind tunnel for small-scale models. Sergio Sartorelli was contacted as an external collaborator for the position of Head of the Styling department giving birth to the following models: Ford Mustang B1 Coupè; Alfa Romeo 2600 “De Luxe” designed by Michelotti; Alfa Romeo 2600 “Presidenziale”; Ford 20M TS Coupe and Spider. In 1966, two more large buildings were built for the series production of the Innocenti 950 Spider.

The Ford 20M TS Coupé

The highlight was the Ford 20M TS Coupé, mainly built for the German market with production reaching 15 cars per day. By shortening the chassis by 20 mm, Sergio Sartorelli created the 20M TS Spider version unveiled at the 1967 Turin Motor Show. The Osi Style Center had an intense production, almost aggressive, thanks to good organization and a highly skilled workforce, discipline, “Team Spirit” and, above all, great enthusiasm and cooperation for a small number of 60 employees made it possible to create the following projects designed by Sartorelli: DAF “City”; Fiat 124 “Cross Country”; Fiat 850 “Weekend”; Alfa Romeo 1600 “Scarabeo”; Bisiluro “Silver Fox”; Fiat 125 Wagon; Fiat 1200 Coupé and Spider and Autobianchi G 31 Coupé.

His work at the Fiat Style Center

The Osi Style Center suddenly ceased to exist in December 1967 after the resignation of Eng. Bianco, and Sartorelli spoke with eng. Giacosa of Fiat, many ex-OSI employees, were incorporated in 1968 into the Fiat Style Center. Sartorelli himself became the “Head of Future Studies.” In 1973, began a period that lasted 16 years which did not allow the use of creativity. This happened because of the change of production needs and the crisis of the car market. Instead of new models development, FIAT went for less expensive restyling, making the “Prototype department ” useless.

The Fiat Ritmo

Despite those problems, Sartorelli managed to create large series production cars such as the Fiat 126, Fiat Bus 950, Fiat Ritmo, the “Lancia” Beta, “the Fiat Regata” and then the Fiat Weekend. Many more models of prototypes followed, especially by the “Tipo 3 Class” (like the Tipo) and the “Tipo 4” (“Croma”), all accompanied by an aerodynamic optimization performed at the Fiat Wind Tunnel with the Fiat Research Center in Orbassano.

The end of his career

In 1984, after 16 years in Fiat as the “Head of Future Studies,” Sartorelli officially retired, with a touch of bitterness and the feeling that the situation of those difficult years, for the car market crisis, had partially eroded, but not at all removed. In fact, in 1984, he founded “Esse Design,” a consultation company for the study and assistance in industrial design. Designer Sergio Sartorelli passed away in 2009.

Molto fonti attribuiscono diversi modelli al designer Sartorelli (come la Autobianchi G31 e l’Alfa Romeo 2600, quest’ultima disegnata da Michelotti come giustamente avete sottolineato), in realtà lui ha seguito il processo produttivo / sviluppo. Ricordiamoci che Sartorelli non era SOLO designer. Come bisogno sottolineare che molti modelli attribuiti a Exner invece sono opera di Sartorelli.

Love the american influence in Sartorelli’s designs!

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.

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.
