In this article, we will explore the key aspects of the 1955 Porsche 550 Spyder, including its history, design, performance, and legacy.

1. History

The Porsche 550 Spyder was introduced in 1953 as the company’s first purpose-built race car. The “550” designation was derived from the car’s 550-kilogram weight. The 1955 model year marked the second generation of the 550 Spyder, featuring various improvements and refinements over its predecessor. This iconic sports car established Porsche as a formidable competitor in international motorsports, with numerous victories in prestigious races like the Targa Florio and Carrera Panamericana.

2. Design

The 1955 Porsche 550 Spyder is a classic sports car known for its sleek and aerodynamic design. Here are some details about its design:

Exterior Design

The Porsche 550 Spyder featured a low-slung and curvaceous body, designed with a focus on aerodynamics to enhance performance. It had a minimalist design approach, with clean lines and smooth surfaces.

The car had a compact and lightweight construction, measuring approximately 3.9 meters (153 inches) in length. The front end had a rounded shape with integrated headlights and a small front grille for cooling.

The rear end featured a distinctive rounded tail section with prominent fenders and a single exhaust outlet. It had a removable lightweight hardtop, and some versions featured a small, removable windshield.

Interior Design

The 550 Spyder had a simple and functional interior, reflecting its racing heritage. The cockpit was designed for the driver, with a minimalistic dashboard and a three-spoke steering wheel.

The instrument cluster consisted of a centrally placed tachometer and speedometer, providing essential information for the driver. The seats were thinly padded and lacked excessive cushioning to reduce weight and provide better feedback to the driver. Interior materials were basic and focused on functionality rather than luxury.

Chassis and Suspension

The Porsche 550 Spyder utilized a tubular space-frame chassis, constructed from lightweight steel or aluminum, which contributed to its low weight. The suspension system consisted of independent front suspension with trailing arms and torsion bars, offering precise handling and a balanced ride. At the rear, it featured swing axles with trailing arms and transverse torsion bars, designed to provide stability and control during cornering.

3. Engine and Performance

The 1955 Porsche 550 Spyder was equipped with a rear-mounted, air-cooled, flat-four engine. Here are the specifications of the engine:

Displacement

The engine had a displacement of 1.5 liters (1498 cc). It’s worth noting that in later versions, Porsche increased the engine size to 1.6 liters (1582 cc) and 1.7 liters (1680 cc) to extract more power.

Configuration

The engine had a horizontally opposed (“flat”) cylinder configuration, with two cylinders on each side facing each other. This design helped keep the engine compact and contributed to a low center of gravity.

Carburetion

The engine utilized dual carburetors, specifically two Solex 40 PJJ carburetors, to provide the necessary fuel-air mixture for combustion.

Horsepower

The engine produced around 110 horsepower at 6,200 rpm. This was quite impressive for a car of its time and contributed to its spirited performance.

Cooling

Being an air-cooled engine, the 550 Spyder’s power plant relied on cooling fins and airflow for heat dissipation. The absence of liquid cooling components helped reduce weight and complexity.

Transmission

The engine was paired with a manual transmission, typically a four-speed gearbox, which transmitted power to the rear wheels.

Performance

Thanks to its lightweight construction and powerful engine, the 550 Spyder delivered impressive performance. It could achieve a top speed of around 135 mph (217 km/h) and accelerate from 0 to 60 mph (0 to 97 km/h) in approximately 9 seconds.

The Porsche 550 Spyder evolved over time, and different versions may have had variations in engine specifications. The information provided here pertains specifically to the 1955 model.

4. Sales and Production

The Porsche 550 Spyder was a limited-production race car, with only around 90 units built between 1953 and 1956. While complete sales figures for the 1955 model year specifically are not readily available, it is clear that the 550 Spyder was a niche product aimed at racing enthusiasts and discerning sports car aficionados.

Production of the 550 Spyder was focused on creating a lightweight, high-performance vehicle that could excel on the racetrack. As a result, the production process was highly specialized, with each car being meticulously crafted to ensure top-quality performance and handling. The limited production numbers contributed to the car’s exclusivity and desirability, both during its production run and in the years that followed.

The 550 Spyder was not intended to be a mass-market product, as Porsche’s focus at the time was on building race cars with the potential to succeed in competitive motorsports events. However, the 550 Spyder’s success on the track, combined with its striking design and impressive performance, helped to establish Porsche as a respected sports car manufacturer and laid the groundwork for the company’s future road cars, such as the iconic Porsche 911.

While production and sales numbers for the 1955 Porsche 550 Spyder were relatively limited due to the car’s specialized nature and niche market, its influence on the automotive world and Porsche’s subsequent successes cannot be understated. The 550 Spyder remains a highly sought-after classic car among collectors and enthusiasts, thanks to its rarity, performance capabilities, and timeless design.
