The Partnership Between Michelotti and Triumph

The history of Triumph in the 20th century is inseparable from the creative genius of Giovanni Michelotti, one of the most influential automotive designers of his time. Triumph, established as the sports division of Standard Triumph in the early 1950s, became synonymous with style, performance, and innovation. The TR (Triumph Roadster) series, which debuted during this period, would grow into a celebrated dynasty, captivating car enthusiasts until the 1980s. Michelotti’s designs not only shaped the identity of Triumph but also elevated the brand into a global icon of British automotive excellence.

The Herald: Triumph’s First Step with Michelotti

In the late 1950s, as the Standard brand was retired, Triumph began a new chapter with the introduction of the Herald in 1959. This compact, modular car marked Michelotti’s debut with Triumph and the start of a collaboration that would define the brand for decades.

The Herald’s design embodied Michelotti’s philosophy of clean, modern lines that balanced elegance with functionality. Its innovative modular construction allowed for a variety of body styles, including saloon, coupe, convertible, and estate, making it versatile and adaptable to different markets. The car was an immediate success and demonstrated Michelotti’s ability to design vehicles that were not only stylish but also practical and market-savvy.

Triumph’s Expansion Under Leyland

Triumph entered a period of significant growth in December 1960, when the Leyland Group acquired Standard Triumph. Under the leadership of Donald Stokes, Triumph’s lineup expanded to include some of its most iconic vehicles, with Michelotti as the driving force behind their design.

Triumph Vitesse (1962): A compact saloon with a powerful six-cylinder engine that combined performance and luxury in a small package.

Triumph 2000 (1963): A mid-size luxury saloon that emphasized refinement and sophistication, competing with larger, more expensive rivals.

Triumph Spitfire (1963): A small, affordable two-seater convertible designed to challenge the MG Midget in the entry-level sports car market.

Triumph GT6 (1966): A fastback coupe variant of the Spitfire, featuring enhanced aerodynamics and a more powerful engine for spirited driving.

Each of these vehicles bore Michelotti’s signature style, blending Italian elegance with British practicality. Their enduring popularity is a testament to his ability to create designs that were both timeless and innovative.

The TR5 Ginevra: A Masterpiece and Turning Point

Among Michelotti’s many contributions to Triumph, the story of the TR5 Ginevra stands out as a defining moment in automotive design. The car was initially conceived as a concept vehicle for the Geneva Motor Show, intended to showcase Michelotti’s vision for Triumph’s next generation of sports cars.

In preparation for the show, Michelotti created a stunning design that he planned to unveil to the public. Before the debut, however, Triumph’s management visited Michelotti’s studio in Turin to preview the car. Upon seeing it, they were awestruck by its beauty and instantly decided it could not be shown as a mere concept. Triumph purchased the design on the spot, intending to develop it into a production model. This project would later become the Triumph Stag, a luxurious grand tourer that cemented Triumph’s reputation for producing stylish and desirable vehicles.

This unexpected development left Michelotti in a bind. With only 15 days remaining before the Geneva Motor Show, he needed to create a replacement car for the event. Working at breakneck speed, Michelotti transformed a TR5 chassis into a completely new spider. Using innovative and practical improvisations—such as repurposing an existing windshield and creating a temporary soft top—he delivered a fully functional prototype in record time.

The TR5 Ginevra’s hastily built successor was exhibited at the show and became a symbol of Michelotti’s remarkable creativity and resourcefulness. The original Ginevra design, meanwhile, laid the foundation for the Triumph Stag, one of the most celebrated vehicles in Triumph’s history. Today, the prototype Ginevra spider still exists and is cherished by a Swiss-German collector who proudly displays it at events across Europe.

Michelotti’s Prototypes and Experimental Design

Michelotti’s collaboration with Triumph extended beyond production models to include various prototypes and experimental projects. One of his early efforts was the Frisky Meadows, a compact car developed for an Egyptian company. While this project never reached production, it demonstrated Michelotti’s versatility and willingness to explore new markets.

Another notable prototype was a small spider based on the TR3, created in response to Triumph’s request for a lightweight, sporty design. Despite being built under tight deadlines, the prototype impressed Triumph’s leadership and helped solidify Michelotti’s role as the brand’s go-to designer.

The Triumph TR3 Speciale built by Vignale

During this period, Michelotti did not yet have his own coachbuilding facilities, relying instead on collaborators like Vignale and Allemano to construct his designs. Despite these logistical challenges, Michelotti consistently delivered groundbreaking vehicles that pushed the boundaries of design and engineering.

The Triumph TR Series and Beyond

The TR series remained a cornerstone of Triumph’s success, with Michelotti playing a pivotal role in its evolution. The TR4, introduced in 1961, marked a significant departure from its predecessors. Michelotti replaced the curvaceous styling of earlier models with sharp, aerodynamic lines and introduced innovative features such as a removable hardtop and wind-down windows.

The TR4’s successor, the TR5, continued this tradition of innovation, incorporating a fuel-injected engine for improved performance. Michelotti’s designs ensured that the TR series retained its appeal while staying at the forefront of sports car development.

Conclusions

Giovanni Michelotti’s partnership with Triumph was more than a collaboration—it was a creative synergy that defined an era of automotive design. From the versatile Herald to the groundbreaking TR5 Ginevra and the iconic Stag, Michelotti’s work left an indelible mark on the automotive world.

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.

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.
