The Bridget Jones of Supercars: A Deep Dive into the De Tomaso Vallelunga

De Tomaso

In the pantheon of Italian automotive history, certain names echo with thunderous applause: Ferrari, Lamborghini, Maserati. Yet, nestled in the shadow of these giants lies De Tomaso—a marque known for raw power, Argentine audacity, and a knack for survival. Among its catalog of V8-powered bruisers and wedge-shaped supercars, one model stands as the anomaly: the De Tomaso Vallelunga.

Produced from 1964 to 1967, the Vallelunga is often described as the “Bridget Jones” of supercars—underappreciated in its time, overshadowed by more glamorous contemporaries, yet possessing a charm and architectural significance that has only deepened with age. It was the first production De Tomaso, a bridge between the racing pedigree of its maker and the road-going grand tourers that would follow. This is the story of the Vallelunga, its evolution, its struggles, and its enduring legacy.

The Genesis: Alejandro de Tomaso’s Gamble

To understand the Vallelunga, one must understand the man behind it. Alejandro de Tomaso was an Argentine racing driver who found his way to Italy in the late 1950s. By the early 1960s, he had established a factory in Modena, initially building racing cars and components for other manufacturers, most notably Cooper.

In 1964, de Tomaso decided to produce a road car that utilized the engineering principles he honed on the track. The goal was to create a lightweight, aerodynamic, mid-engined coupe that could rival the contemporary Ferrari Dino 206 GT. The result was the Vallelunga.

The Prototype: The Genesis of 1964

The journey began with the “Prototipo” or Prototype, unveiled at the Turin Motor Show in 1964. This was not merely a concept; it was a functional testbed that would evolve into the production model.

  • The Heart (Engine): The prototype utilized a Ford 1600cc pre-Crossflow inline-four engine. This was a critical strategic move. De Tomaso had a close relationship with Ford, and using a reliable, mass-produced engine (as opposed to a bespoke Italian unit) kept costs down and serviceability high. The engine was tuned by Cosworth, featuring dual overhead camshafts (DOHC) and dry-sump lubrication—features usually reserved for pure race cars.
  • The Chassis: The most revolutionary aspect was the chassis. It featured a tubular space frame, a technique perfected by Cooper in Formula One. This allowed for a lightweight structure (weighing under 700 kg / 1540 lbs) that was incredibly rigid.
  • The Body: The design was penned by Scaglietti, the legendary coachbuilder responsible for many early Ferraris. The body was sleek and low-slung, a classic “double-bubble” roof design that provided headroom for tall drivers while maintaining aerodynamic efficiency.

The Production Vallelunga (1965–1967)

Following the positive reception of the prototype, De Tomaso began production in late 1964. The production run was short, lasting roughly two and a half years, and remarkably consistent in terms of model variations. Unlike modern manufacturers that flood the market with trim levels, De Tomaso offered the Vallelunga in essentially one definitive configuration, with minor factory and dealer-installed options.

Technical Specifications and Architecture

The production Vallelunga was an exercise in motorsport engineering adapted for the road.

  1. Chassis and Body:
    • Construction: Tubular space frame with aluminum body panels.
    • Suspension: Fully independent suspension utilizing double wishbones at all four corners—a setup derived directly from Formula One. The rear suspension was particularly complex, featuring a reversed wishbone arrangement to accommodate the inboard brakes and transmission.
    • Brakes: Four-wheel Girling disc brakes. Notably, the rear brakes were mounted inboard (inside the transmission housing) to reduce unsprung weight and improve handling.
    • Wheels: Cromodora alloy wheels (15-inch), shod with Pirelli CN36 tires.
  2. The Powerplant:
    • Engine: Ford Taunus 1600 GT (V4) or the updated 1600 GT Special. However, the most common and desirable configuration was the Ford 1600 Crossflow Inline-Four, tuned by Cosworth.
    • Output: Approximately 105 horsepower (77 kW) at 6,000 rpm. While modest by today’s standards, in a car weighing barely 700 kg, this provided a power-to-weight ratio comparable to the Porsche 911 of the era.
    • Transmission: 5-speed manual gearbox (ZF or Citroën, depending on the specific production batch).

Trim Levels and Variations

Here lies the complexity of the Vallelunga story. While there were no “Luxury” or “Sport” trim badges applied by the factory, the evolution of the car created distinct iterations that collectors now distinguish.

1. The Early Production (1964–1965):

  • Features: These cars closely resembled the 1964 prototype. They often featured slightly different headlight nacelles and rear taillight configurations.
  • Engine: Early cars utilized the Ford Taunus V4 engine (specifically the 1600E version). This was a narrow-angle V4, distinct from the inline-four found in later models.
  • Interior: Very sparse. Bucket seats, wood-rim steering wheel, and Veglia instrumentation.

2. The Mid-Production / The “Standard” Vallelunga (1965–1966):

  • The Shift to Inline-Four: As production settled, De Tomaso switched from the V4 to the Ford 1600 Crossflow inline-four. This engine was lighter, revved higher, and was easier to tune.
  • Cosworth Tuning: The engines were blueprinted and tuned by Cosworth in England, featuring twin Weber carburetors (often 40 DCOE or 38 mm DCN).
  • Body Details: Minor changes to the air intakes and side windows. The “double bubble” roof became more pronounced.

3. The Late Production / “1600 GT” (1967):

  • The Final Evolution: Towards the end of production, the car was sometimes referred to as the De Tomaso 1600 GT.
  • Engine Tweaks: Slightly higher compression ratios and improved camshaft profiles, pushing horsepower closer to 110-115 bhp.
  • Suspension Tuning: Stiffer anti-roll bars and revised spring rates based on data gathered from early racing successes.

4. The Vallelunga Corsa (Racing Variant):

  • While not a “trim level” sold to the public, the Corsa was a factory racing package offered to privateers.
  • Modifications: The engine capacity was often bored out to 1.8 liters, generating up to 140 horsepower. The body was stripped of chrome trim, plexiglass windows replaced the side glass, and the interior was stripped bare with a full roll cage.
  • Legacy: The Corsa versions competed in the European Touring Car Championship and various hill climbs, proving the chassis’s dominance.

Market Reception and Production Numbers

When the Vallelunga was launched, it cost approximately 2,300,000 Lira. For comparison, a Ferrari Dino 206 GT cost nearly twice as much. In theory, this should have made the De Tomaso a bestseller.

In reality, the car suffered from the “Bridget Jones” syndrome. It was overshadowed by the Dino, which had the Ferrari badge and a screaming V6. Additionally, the De Tomaso factory was small, and build quality varied. Early cars suffered from reliability issues, particularly with the bespoke bodywork and cooling systems.

Production numbers are notoriously difficult to pin down due to the chaotic nature of the Modena factory, but consensus places the total production figure between 225 and 245 units. Of these:

  • Approximately 50-60 were V4 engines.
  • The vast majority were the 1600 Inline-Four.
  • Only a handful (estimated fewer than 10) were true factory Corsa models.

Ownership Experience: The “Bridget Jones” Factor

Owning a Vallelunga today is a paradox. It is a “Bridget Jones” car because it is rarely the first choice for collectors—who flock to the more famous De Tomaso Pantera—but it rewards those who choose it with a uniquely pure driving experience.

  • The Drive: The steering is unassisted and incredibly direct. The cabin is hot, loud, and vibrates with mechanical fury. The ZF gearbox has a rifle-bolt precision. Because the engine is directly behind your head, the induction roar is intoxicating.
  • The Quirks: The rear window is a single piece of curved Perspex that tends to craze with age. The side windows operate on a slide mechanism that often jams. The fuel filler cap is often located inside the engine bay, a strange engineering quirk.
  • The Charm: Despite the quirks, the car is beautifully balanced. The rear weight bias (around 45/55) allows for enthusiastic cornering without the snap oversteer of the later Pantera. It is a gentle giant, fast enough to thrill but light enough to feel playful.

Racing Pedigree

The Vallelunga was never intended to be a static showpiece. De Tomaso entered three Vallelungas in the 1965 24 Hours of Le Mans. Two retired, but one, driven by Masi and Lualdi, finished 14th overall and 2nd in class—a remarkable achievement for a debutant manufacturer against the might of Porsche and Ferrari.

This success trickled down to the production cars. The chassis proved so capable that it inspired the geometry for future De Tomaso prototypes, including the Deauville and the Pantera.

The End of the Road and the Legacy

By 1967, the automotive landscape was shifting. The public wanted more power and more luxury. De Tomaso, looking to expand, moved toward the larger, V8-powered Mangusta (and subsequently the Pantera, built in conjunction with Ford).

The Vallelunga was discontinued, leaving a brief but impactful footnote in automotive history.

Current Status and Future Outlook

Today, the Vallelunga is a collector’s gem. Its rarity and historical significance—being the first production De Tomaso—command high prices at auction. In the early 2000s, you could find a Vallelunga for a reasonable sum; today, pristine examples can fetch between $150,000 and $300,000.

The future outlook for the Vallelunga is bright. As the market moves away from modern supercars with digital driver aids and heavy curb weights, the analog purity of the Vallelunga becomes increasingly attractive.

  • Restomod Trend: We are seeing a rise in “restomods” where the original chassis is retained, but the engine is swapped for a modern Ford Ecoboost unit or a tuned Zetec engine. While purists may scoff, this ensures the survival of the chassis for future generations.
  • Homologation: As the car passes the 50-year mark, it qualifies for historic racing licenses in FIA-sanctioned events, sparking renewed interest from vintage racers.

Conclusion

The De Tomaso Vallelunga is a vehicle of contradictions. It is Italian in design but powered by American Ford engineering. It is a road car built with the soul of a racer. It is beautiful yet understated, rare yet undervalued.

Like Bridget Jones, it may not have been the obvious choice at the time, overshadowed by more boisterous peers. But for those who look past the badge and the fame, the Vallelunga reveals itself as a masterpiece of engineering—a lightweight, mid-engined wedge that helped launch one of Italy’s most enduring automotive sagas. It stands not just as a car, but as the genesis of the De Tomaso legend.
