The Audi 50: A Pioneering Supermini

The Audi 50, a name largely unfamiliar to those outside of Europe, holds a significant place in automotive history. Produced from 1974 to 1978, it was a groundbreaking supermini that not only laid the foundation for the Volkswagen Polo but also showcased Audi's engineering prowess in a smaller, more affordable package. It represented Audi's first foray into the burgeoning supermini market, offering a combination of practicality, efficiency, and surprisingly good performance for its size.

Generations

The Audi 50 had a relatively short production run, encompassing essentially a single generation. However, subtle improvements and variations were introduced over its lifespan.

• Mk1 (1974-1978): The only generation of the Audi 50. Key features included:
  • Available in two main variants: 50 LS and 50 GL. The GL offered a slightly higher level of trim and equipment.
  • Front-wheel drive configuration.
  • A transverse-mounted engine, a layout that maximized interior space.
  • Relatively lightweight construction, contributing to good fuel economy and nimble handling.
  • Early models (1974-1975) had a slightly different dashboard layout and some minor trim differences compared to later models.

Reliability & Common Issues

Given its age, sourcing parts for an Audi 50 can be a challenge. However, the underlying engineering is generally robust. Here's a breakdown of common issues:

Engine

The Audi 50 utilized a range of small-capacity petrol engines, primarily based on the Volkswagen EA111 engine family. The engines are generally reliable if properly maintained.

• Carburetor Issues: The carburetor is often a source of problems, particularly in older vehicles. Dirty jets, vacuum leaks, and incorrect settings can lead to poor running, difficulty starting, and increased fuel consumption. Rebuilding or replacing the carburetor may be necessary.
• Timing Belt: Regular replacement of the timing belt is crucial to prevent catastrophic engine damage. Follow the manufacturer's recommended service intervals religiously.
• Oil Leaks: Check for oil leaks from the valve cover gasket, oil pan gasket, and crankshaft seals. These are common issues in older engines.
• Cooling System: The cooling system is prone to corrosion and leaks. Inspect the radiator, hoses, and water pump regularly. Ensure the system is properly flushed and filled with the correct coolant.

Transmission

The Audi 50 featured a 4-speed manual transmission. While generally reliable, these are the things you should look out for:

• Worn Synchros: Difficulty shifting into certain gears, especially second and third, may indicate worn synchros. A rebuild might be required.
• Clutch Wear: Check for slippage, chattering, or a high clutch pedal engagement point, all signs of a worn clutch.
• Gear Linkage: The gear linkage can become loose or worn, leading to sloppy or imprecise shifting. Adjusting or replacing the linkage components can improve shift quality.

Suspension and Steering

The suspension and steering systems are relatively simple but can suffer from wear and tear.

• Worn Suspension Bushings: Worn bushings can cause excessive play in the suspension, leading to poor handling and increased tire wear. Inspect the bushings regularly and replace them as needed.
• Worn Ball Joints and Tie Rod Ends: These components are subject to wear and tear and can affect steering precision. Check for play and replace them if necessary.
• Rust: Rust is a significant concern, particularly in areas with harsh winters. Inspect the suspension components, chassis, and bodywork for rust.

Electrical System

The electrical system is relatively basic but can be prone to issues due to age and corrosion.

• Wiring Issues: Check for cracked or corroded wiring, especially in the engine bay and under the dashboard.
• Faulty Relays and Switches: Relays and switches can fail over time, leading to problems with lights, wipers, and other electrical components.
• Battery Drain: A parasitic battery drain can be a common issue. Use a multimeter to identify the source of the drain.

Driving Experience

The Audi 50 offers a surprisingly engaging driving experience, particularly for its age and size.

Pros:

• Nimble Handling: The lightweight construction and responsive steering make the Audi 50 fun to drive on twisty roads.
• Fuel Efficiency: The small-capacity engines offer good fuel economy, making it a practical choice for city driving.
• Compact Size: The compact dimensions make it easy to maneuver and park in tight spaces.
• Simplicity: Its relative simplicity makes it easier to work on compared to more modern cars.

Cons:

• Limited Performance: The small engines offer limited performance, particularly when fully loaded or climbing hills.
• Basic Interior: The interior is basic and lacks modern amenities.
• Spare Parts Availability: Sourcing spare parts can be challenging and expensive.
• Safety: Lacking modern safety features, the Audi 50 provides significantly less crash protection compared to modern cars.

Buying Advice

If you're considering buying an Audi 50, here's some advice:

• Condition is Key: Given the age of these cars, condition is paramount. Look for a well-maintained example with minimal rust.
• Focus on Mechanicals: Pay close attention to the engine, transmission, and suspension. Have a mechanic inspect the car thoroughly before you buy it.
• Check for Rust: Rust is a major enemy of these cars. Inspect the bodywork, chassis, and suspension components for rust. Pay particular attention to areas around the wheel arches, sills, and floor pan.
• Documented History: A car with a comprehensive service history is always preferable. This will give you a better understanding of how well the car has been maintained.
• Parts Availability: Research parts availability before you buy the car. Certain parts may be difficult or expensive to source.
• Consider the Volkswagen Polo: Since the Audi 50 was essentially rebadged as the Volkswagen Polo, consider purchasing a Polo instead. Parts availability and overall cost of ownership will likely be lower.
• What to avoid: Anything with significant rust, signs of neglect or poor maintenance.

In conclusion, the Audi 50 is a charming and historically significant supermini. While owning one requires dedication and a willingness to deal with the challenges of maintaining a classic car, it can be a rewarding experience for the right enthusiast.
