Audi F103 Series (Audi 72, 75, 80, Super 90): A Comprehensive Guide
The Audi F103 series, encompassing the Audi 72, 75, 80, and Super 90, marked Audi's re-entry into the automotive market after its acquisition by Volkswagen in 1964. Produced from 1965 to 1972, these models were pivotal in establishing Audi as a respected brand known for its engineering and quality. These cars occupy the mid-size family car segment, offering a comfortable and practical option for families and individuals alike.
Generations
The F103 series didn't undergo radical generational shifts like modern cars. Rather, it evolved incrementally, receiving updates to its engine, trim, and features throughout its production run. Think of it as a single generation with notable variants.
- 1965: Audi 72 (F103) - The initial model, featuring a 1.7-liter four-cylinder engine producing 72 horsepower. This marked the beginning of the F103 series and the modern Audi era.
- 1966: Audi 80 (F103) - Introduced alongside the 72, offering a slightly more powerful version of the 1.7-liter engine, now producing 80 horsepower. This provided a modest performance upgrade.
- 1966: Audi Super 90 (F103) - The flagship model, equipped with a more potent 1.8-liter four-cylinder engine delivering 90 horsepower. It also featured enhanced trim and interior appointments, setting it apart as the premium offering.
- 1969: Audi 75 (F103) - Replaced the Audi 72. This model retained the 1.7 liter engine but received some refinements that increased overall driveability.
- Minor Updates (Throughout Production): These included cosmetic changes such as grille designs, interior fabrics, and the addition of optional equipment like headrests and improved ventilation systems.
Reliability & Common Issues
The Audi F103 series is known for its robust build quality, a characteristic of German engineering of the era. However, given their age, certain issues are commonly encountered:
Engine
- Carburetor Problems: The Solex carburetor, used across the range, can be prone to clogging and require regular cleaning and tuning. Finding a skilled mechanic familiar with these carburetors is crucial.
- Cooling System Leaks: The cooling system, including the radiator and hoses, can develop leaks over time due to age and corrosion. Regular inspection and replacement of worn components are essential to prevent overheating.
- Oil Leaks: Like many older engines, the F103 series engines can develop oil leaks from various seals and gaskets. Addressing these promptly helps maintain proper oil levels and prevent damage.
Transmission
- Manual Transmission Wear: The manual transmissions are generally reliable but can experience wear in the synchromesh rings, leading to difficulty shifting gears, especially into second gear.
Suspension & Brakes
- Suspension Bushing Wear: Rubber bushings in the suspension system can degrade, leading to loose handling and increased noise. Replacement of these bushings can significantly improve ride quality and handling.
- Brake System Issues: The drum brakes (typically found on earlier models and at the rear of later ones) can suffer from brake fade and require regular adjustment. Inspecting and maintaining the brake cylinders, shoes, and lines is critical for safety.
Body & Electrics
- Rust: The F103 series is susceptible to rust, especially in areas like the wheel arches, floor pans, and around the windshield. Thorough inspection for rust is essential before purchasing.
- Electrical Issues: Wiring can become brittle and corroded with age, leading to electrical problems such as faulty lights, non-functional gauges, and starting issues. Carefully inspect the wiring harness and connections.
- Interior Wear: The interior trim, including seats, carpets, and dashboards, can show signs of wear and tear. Replacements can be difficult to find and expensive.
Driving Experience
The Audi F103 series offers a classic driving experience that is both charming and engaging. It's not a performance car by modern standards, but it offers a unique and rewarding driving experience.
Pros:
- Comfortable Ride: The suspension provides a comfortable ride, absorbing bumps and imperfections in the road.
- Good Handling: For its time, the F103 series offered respectable handling, making it a pleasant car to drive on winding roads.
- Classic Styling: The F103 series boasts a timeless design that remains appealing to this day.
- Simple Mechanics: Compared to modern cars, the F103 series is relatively simple to work on, making it a rewarding project for enthusiasts.
Cons:
- Limited Performance: The engine power is modest, making acceleration and overtaking maneuvers somewhat slow.
- Drum Brakes (on some models/axles): Drum brakes offer less stopping power than disc brakes, requiring more attention to stopping distances.
- Parts Availability: Finding replacement parts can be challenging and expensive, requiring patience and resourcefulness.
- Fuel Economy: Fuel economy is not a strong point, especially compared to modern cars.
Buying Advice
Purchasing an Audi F103 series car requires careful consideration and a thorough inspection. Here's some advice:
Years to Look For:
- Audi Super 90: The Super 90 models are generally more desirable due to their more powerful engine and upgraded trim.
- Later Production Years (1970-1972): Later models may benefit from minor improvements and refinements implemented throughout the production run.
What to Avoid:
- Extensive Rust: Avoid cars with significant rust damage, as repairing it can be costly and time-consuming.
- Major Mechanical Issues: Steer clear of cars with significant engine or transmission problems, unless you're prepared for a major overhaul.
- Modified or Neglected Examples: Original and well-maintained examples are generally more desirable and easier to work on.
Inspection Checklist:
- Body: Inspect for rust in common areas, such as wheel arches, floor pans, and around the windshield.
- Engine: Check for oil leaks, unusual noises, and smooth running.
- Transmission: Test all gears for smooth engagement and listen for any grinding or unusual noises.
- Brakes: Ensure the brakes are responsive and free from excessive noise.
- Suspension: Check for worn bushings and any signs of damage.
- Electrics: Test all lights, gauges, and electrical components for proper function.
- Interior: Examine the interior for wear and tear, and check the condition of the upholstery, carpets, and dashboard.
Ultimately, purchasing an Audi F103 series car is a journey back in time, offering a unique and rewarding driving experience. With careful research, a thorough inspection, and a willingness to maintain it, you can enjoy the charm and character of this classic Audi.
