The Volvo P1800: A Comprehensive Guide

The Volvo P1800 is an iconic sports car that transcended its humble beginnings to become a symbol of Swedish design and engineering. Initially conceived as a competitor to popular European sports cars like the MG and Triumph, the P1800 gained international fame through its association with the television series "The Saint," starring Roger Moore. More than just a pretty face, the P1800 is renowned for its reliability and longevity, making it a desirable classic car today.

A Brief History

Developed in the late 1950s, the P1800 was Volvo's second attempt at a sports car, following the short-lived P1900. Facing production limitations in Sweden, Volvo initially contracted Pressed Steel in Scotland to build the bodies, which were then shipped to Jensen Motors in England for assembly. Production eventually shifted to Sweden in the late 1960s, and the car remained in production until 1973, evolving from a coupe to a distinctive shooting brake in its final years.

Class of Car

The Volvo P1800 falls into the category of a 2+2 grand tourer (GT). While it boasts sporty styling, its emphasis on comfort, reliability, and long-distance cruising capabilities distinguishes it from a pure sports car. The rear seats are small and best suited for occasional use or luggage. The later ES models with their shooting brake configuration offer increased cargo capacity, further emphasizing their GT nature.

Generations of the Volvo P1800

P1800/P1800S (1961-1969)

  • Years: 1961-1969
  • Key Features: The original P1800 was launched with B18 engine (1.8L) and initially built by Jensen in England. Later, production was moved to Sweden and the name changed to P1800S.
  • Engine Changes: The B18 engine received incremental improvements throughout its run, including increased horsepower and refined carburation.
  • Visual Changes: Subtle changes to the grille, trim, and interior occurred over the years.
  • Mechanical Changes: Disc brakes were introduced on the front axle early in the production run.

1800E (1970-1972)

  • Years: 1970-1972
  • Key Features: Introduction of fuel injection (Bosch D-Jetronic) for improved performance and efficiency.
  • Engine: B20E engine (2.0L) offered increased power compared to the previous models.
  • Brakes: All four wheels equipped with disc brakes, enhancing braking performance.
  • Exterior: New grille design, and deletion of some brightwork.

1800ES (1972-1973)

  • Years: 1972-1973
  • Key Features: Unique shooting brake body style with a frameless glass tailgate. Final production run of the P1800 series.
  • Engine: Continued use of the B20E engine with fuel injection.
  • Suspension: Minor suspension revisions to accommodate the increased weight and altered weight distribution.

Reliability & Common Issues

Engine

  • B18/B20 Reliability: The B18 and B20 engines are known for their exceptional durability and longevity. Regular maintenance, including oil changes and valve adjustments, is key to maximizing their lifespan. Many examples have exceeded 200,000 miles without major overhauls.
  • Oil Leaks: Oil leaks are common, particularly from the rear main seal, valve cover gasket, and oil pan gasket. These are typically manageable and relatively inexpensive to address.
  • Carburetor Issues (Pre-1800E): SU carburetors, used in pre-fuel injection models, require periodic tuning and can be susceptible to wear and tear, leading to running issues.
  • Fuel Injection Issues (1800E/ES): The Bosch D-Jetronic fuel injection system is generally reliable but can suffer from issues related to faulty sensors, wiring corrosion, and fuel pump failures. Diagnosing D-Jetronic problems can be challenging and may require specialized knowledge.

Transmission

  • Manual Transmission: The manual transmissions are robust and reliable, but synchros can wear over time, especially in the lower gears. Listen for grinding noises during gear changes.
  • Automatic Transmission: The automatic transmissions are generally reliable but can be prone to slippage and overheating if not properly maintained. Regular fluid changes are crucial.

Electrical System

  • Wiring: Like many classic cars, the P1800 can suffer from wiring issues, including corrosion, brittle insulation, and poor connections. Carefully inspect the wiring harness for any signs of damage.
  • Lucas Electrical Components: Some P1800s used Lucas electrical components (particularly earlier models). While not inherently unreliable, these components can be more susceptible to corrosion and failure than modern equivalents.
  • Overdrive Unit: Many P1800s were equipped with a Laycock de Normanville overdrive unit. These units can be prone to failure, particularly if the oil level is not properly maintained.

Body & Chassis

  • Rust: Rust is a significant concern, especially in areas prone to moisture, such as the rocker panels, floors, wheel wells, and around the windshield and taillights. Thoroughly inspect the car for any signs of rust before purchasing.
  • Body Panels: Replacement body panels can be difficult and expensive to source. Pay close attention to the condition of the bodywork and be prepared for potential restoration costs.
  • Suspension: The suspension is relatively simple and reliable, but components such as bushings, ball joints, and shocks will eventually wear out and require replacement.

Driving Experience

Pros

  • Classic Styling: The P1800's timeless design continues to turn heads.
  • Reliability: Properly maintained, the P1800 is a remarkably reliable classic car.
  • Comfortable Ride: The P1800 offers a surprisingly comfortable ride, making it suitable for long-distance cruising.
  • Parts Availability: Parts availability is generally good, thanks to a dedicated network of suppliers and enthusiasts.
  • Strong Community Support: A vibrant community of P1800 owners and enthusiasts provides valuable support and resources.

Cons

  • Performance: While adequate, the P1800's performance is not comparable to modern sports cars.
  • Handling: The handling can feel somewhat dated compared to modern vehicles.
  • Rust Susceptibility: Rust can be a significant issue, requiring costly repairs.
  • Ergonomics: Some ergonomic aspects, such as the seating position and pedal placement, may not be ideal for all drivers.

Buying Advice

Years to Look For

  • 1800E (1970-1972): These models offer the best combination of performance, reliability, and features, including fuel injection and four-wheel disc brakes.
  • 1800ES (1972-1973): The shooting brake design is unique and desirable, offering increased practicality.

Years to Be Cautious Of

  • Early Jensen-Built Models (1961-1963): While historically significant, these models can be more prone to rust and build quality issues due to the outsourced production.

What to Avoid

  • Cars with Significant Rust: Avoid cars with extensive rust damage, as repairs can be costly and time-consuming.
  • Cars with Poorly Maintained Fuel Injection Systems (1800E/ES): Be wary of cars with running problems or evidence of tampering with the fuel injection system.
  • Cars with Extensive Modifications: Heavily modified cars may be difficult to maintain and may not retain their value.

Pre-Purchase Inspection

Before purchasing a Volvo P1800, it is essential to have it thoroughly inspected by a qualified mechanic with experience in classic cars. Pay close attention to the following areas:

  • Rust: Inspect all areas prone to rust, including the rocker panels, floors, wheel wells, and around the windshield and taillights.
  • Engine: Check for oil leaks, unusual noises, and signs of overheating. Perform a compression test to assess the engine's condition.
  • Transmission: Check for smooth gear changes and any signs of slippage or grinding.
  • Electrical System: Verify that all lights, gauges, and accessories are working properly.
  • Overdrive Unit (if equipped): Test the overdrive unit to ensure that it engages and disengages smoothly.
  • Brakes: Check the condition of the brake lines, calipers, and rotors. Ensure that the brakes are functioning properly.

Buying a Volvo P1800 can be a rewarding experience, offering a blend of classic style, reliability, and driving pleasure. By carefully researching the different generations and common issues, and by conducting a thorough pre-purchase inspection, you can increase your chances of finding a well-maintained example that will provide years of enjoyment.
