The Mercedes-Benz W136 (170 V): A Comprehensive Guide

The Mercedes-Benz W136, most commonly known as the 170 V, is a compact automobile introduced by Daimler-Benz in 1936. Representing a significant step forward for Mercedes-Benz, it was their first mass-produced, affordable passenger car. Its development predates World War II, but production continued both before and after the war, playing a crucial role in the company's post-war recovery. The "V" in its name stands for "Vorn," meaning "front" in German, indicating its modern (for the time) front-engine, rear-wheel-drive configuration, contrasting with some earlier Mercedes models.

Generations & Key Changes

• 1936-1942 (Pre-War Production):
  • Original introduction as the 170 V.
  • Powered by a 1.7-liter four-cylinder sidevalve engine producing approximately 38 hp.
  • Available in a wide range of body styles including Saloon (sedan), Cabriolet A (two-seater), Cabriolet B (four-seater), and various commercial vehicle derivatives.
  • Hydraulic brakes and independent front suspension were relatively advanced for the era.
• 1946-1955 (Post-War Production):
  • Re-introduction of the 170 V after the war, initially focusing on commercial vehicles to aid in reconstruction.
  • Gradual resumption of passenger car production.
  • Minor styling updates, primarily focused on practicality and ease of manufacturing.
  • 170 D (1949-1953): Introduction of a diesel variant, using a 1.7-liter four-cylinder diesel engine. This was a significant development, making Mercedes-Benz a pioneer in diesel passenger cars. Power output was around 38 hp.
  • 170 S (1949-1955): A more luxurious and refined version, featuring a larger 1.8-liter engine (M136) producing around 52 hp, and improved suspension and interior appointments. Visually distinguishable by its wider grille and more prominent chrome trim.
  • 170 Va/Vb (Gradual Updates): Minor running changes and improvements were implemented throughout the production run, designated as Va and Vb models. These included improvements to the brakes, electrical systems, and interior features.

Reliability & Common Issues

The Mercedes-Benz 170 V is known for its robust and simple engineering, which contributes to its relative reliability, especially considering its age. However, potential buyers should be aware of the following:

Engine:

• Sidevalve Design: The sidevalve engine is relatively simple but less efficient than overhead valve or overhead cam designs. Expect lower power output and fuel economy compared to modern cars.
• Wear and Tear: Given their age, engines are likely to have experienced significant wear and tear. Look for signs of oil leaks, excessive smoke, and unusual noises. A compression test is highly recommended.
• Cooling System: Overheating can be a problem, especially in warmer climates. Inspect the radiator for leaks and ensure the cooling system is functioning correctly.
• Diesel Engines (170 D): Diesel engines are generally durable, but injector problems and fuel pump issues can occur. Glow plugs may need replacement.

Transmission:

• Manual Gearbox: The four-speed manual gearbox is generally reliable, but worn synchromesh can lead to difficulty shifting gears, particularly into second.
• Clutch: Check for clutch slippage, which indicates a worn clutch plate.

Suspension & Brakes:

• Independent Front Suspension: While advanced for its time, the independent front suspension can suffer from wear in the bushings and joints. Inspect for play and noises.
• Rear Suspension: The rear suspension uses leaf springs, which are generally robust but can become worn and sag over time.
• Hydraulic Brakes: The hydraulic brake system is relatively simple, but brake lines can corrode and leak. Regular maintenance and inspection are essential. Replacing brake lines and rebuilding brake cylinders are common tasks.

Body & Chassis:

• Rust: Rust is a major concern, particularly in areas with harsh winters or coastal climates. Inspect the floors, sills, wheel arches, and body panels carefully.
• Wood Framing (Cabriolets): Cabriolet models often have wood framing that can rot and deteriorate over time. Thorough inspection is crucial.

Electrical System:

• 6-Volt System: The 6-volt electrical system can be less reliable than modern 12-volt systems. Ensure all components are functioning correctly, and be aware that finding replacement parts for a 6-volt system can be challenging.
• Wiring: Original wiring can become brittle and cracked over time, leading to shorts and other electrical problems.

Driving Experience

Driving a Mercedes-Benz 170 V is a unique experience that offers a glimpse into a bygone era. It's not about speed or modern conveniences; it's about appreciating the craftsmanship and engineering of a classic automobile.

Pros:

• Classic Styling: The 170 V possesses a timeless elegance and charm that is sure to turn heads.
• Simplicity: Its simple mechanical design makes it relatively easy to maintain and repair, provided you have the knowledge and resources.
• Historical Significance: Owning a 170 V is owning a piece of automotive history.
• Community: A strong community of enthusiasts exists, offering support, advice, and parts resources.

Cons:

• Performance: Performance is leisurely by modern standards. Acceleration is slow, and top speed is limited.
• Comfort: Ride quality is acceptable for its time, but not as smooth or refined as modern cars.
• Safety: Safety features are minimal compared to modern vehicles. Brakes are less effective, and there are no seatbelts or airbags.
• Parts Availability: While some parts are readily available, others can be difficult and expensive to source.

Buying Advice

Purchasing a Mercedes-Benz 170 V requires careful consideration. Here's some advice to help you make an informed decision:

What Years to Look For:

• Post-War Models (1946-1955): While pre-war models are historically significant, post-war models are generally easier to find and may be in better condition due to more recent restoration efforts.
• 170 S: The 170 S offers a more refined driving experience and is a desirable model for collectors.

What to Avoid:

• Extensive Rust: Avoid cars with significant rust damage, as repairing rust can be expensive and time-consuming.
• Heavily Modified Cars: Unless you are specifically looking for a modified car, stick to original or well-restored examples.
• Incomplete Projects: Unless you are an experienced restorer, avoid cars that are incomplete or require extensive restoration.

Key Considerations:

• Condition: Prioritize condition over rarity. A well-maintained or restored car is usually a better investment than a rare car in poor condition.
• Provenance: Research the car's history and ownership. Verify its authenticity and mileage if possible.
• Inspection: Have the car inspected by a qualified mechanic familiar with vintage Mercedes-Benz vehicles before making a purchase.
• Budget: Set a realistic budget that includes the purchase price, restoration costs (if any), and ongoing maintenance expenses.
• Parts Availability: Research the availability of spare parts before buying a car.
• Community Support: Join a Mercedes-Benz club or online forum to connect with other enthusiasts and gain valuable insights.

Buying a Mercedes-Benz 170 V can be a rewarding experience, providing you with a unique opportunity to own and drive a classic automobile. By following this guide and doing your research, you can make an informed decision and find the perfect 170 V for your needs.
