When we talk about German cars, we think about things like German engineering, precise and disciplined, or quality, reliability and performance with brands such as BMW, Mercedes, Porsche or Volkswagen but behind that quite organized face is a whole parallel history, more experimental, where engineers and designers came outside of their typical role to discover even “weirder” shapes that looked nothing like the rules of car design as we knew it.

Over the decades, Germany came up with some very strange machines which never have been intended to be practical and commercial, some of them built when the world was trying to recover, other when designers was already thinking of a future completely different. They are the representation of those times when the goal was to have an innovative, aerodynamic and light machine instead of a commercial success.

1. Schlörwagen

The Schlrwagen resembled something out of a science-fiction proposal; this is due to the aerodynamic and streamlined, teardrop-shaped body. Built by Karl Schlr in 1939, it was designed to minimize air resistance. The aluminum-bodied car was fitted onto a Mercedes chassis and took car shape/airflow design back to the drawing board.

Aerodynamic Innovation & Design Features:

• Teardrop shaped aerodynamic body
• Lightweight aluminum construction design
• Mercedes chassis engineering base
• Strong focus on drag reduction

The Schlrwagen was a surprising success and displayed excellent performance data for the time even considering its odd look. Very low drag enabled it to hit reasonable speeds in relation to the other cars being driven at the time. Unfortunately however, this groundbreaking design was too radical to be adopted by the general public and most saw it as peculiar rather than futuristic. 

The car and its testing were eventually abandoned with the arrival of World War II. Today it remains one of the earliest and most radical experiments in aerodynamic automobile design. It set the stage for all subsequent streamlining of automobile designs and aerodynamic flow testing techniques. The Schlrwagen can truly be seen as a vehicle prototype of the future.

2. Kleinschnittger F125

The Kleinschnittger F125 came about in the post-war era as a token to survival and pragmatic engineering. Designed by Paul Kleinschnittger, the F125 was made from whatever materials were available to the craftsman; discarded scrap metal, and second hand parts were the normal building materials used for the vehicle. The car is very light weight, very basic and very cheap. The car was made as simple and cheap as possible to be used by the working man to fill the very basic transport needs.

Post-War Innovation & Design Features:

• Built from scrap and recycled materials
• Extremely lightweight simple structure
• Minimalist affordable transportation design
• Small-scale early production model

In small numbers due to economic constraints and great demand for cheap transport, production began on the Kleinschnittger F125. Every aspect of the car displayed ingenious and practical engineering with limited means. The simplicity of the vehicle meant practical transport for a multitude of people, an ingenious piece of kit that provided what was needed when very little was available. It stands as a strong testament to post-war automotive design ingenuity.

3. Hoffman

The Hoffman was originally designed in 1951 by Michael Hoffman. He was a foreman in a workshop in Munich and had built himself his own car with limited materials. It was made from a collection of odds and sods, which were not originally intended for use in a car. The car was in an unusual and experimental construction. There was no standard industrial plan that was being followed, instead the car is a product of individual design.

Independent Build & Experimental Features:

• Built from spare and reused parts
• Highly unconventional construction design
• Lightweight and simple mobility focus
• One-off experimental vehicle creation

In a word, simplicity, light-weight and cost were the chief purpose for designing Hoffman. A pragmatic tool that gives a man transportation, using only materials that were available at the moment. However, the vehicle itself looked a little odd both in shape and comfort. And it had only ever produced one machine. It could be classified as a singular work rather than something intended to be put into manufacture, it seemed more to be a personal experiment of engineering.

Hoffman itself is today a symbol of individual engineering enthusiasm and innovation. A testimony of man who tried to build something to drive himself without the help of manufacturing facilities. At last it is simply the fruit of the individual pursuit of curiosity, ingenuity, and determination.

4. Brütsch Mopetta

The Brtsch Mopetta is minimalism taken to extremes in car design. Designed simply as a minimal and single seat microcar to provide essential transport. Egg shaped, it was highly unusual and easily recognizable in a world of cars and focused entirely on being lightweight and basic rather than comfortable and practical. One of the smallest most unusual cars.

Ultra-Compact Microcar & Design Features:

• Single seat ultra-compact microcar
• Egg-shaped minimal body design
• Lightweight essential mobility focus
• Simple structure and construction

In spite of its visually attractive design, this first prototype has design limitations due to its unstable construction and is practically impossible to drive and maneuver in everyday life. Due to its light construction, the car is very easy to steer but also raises a number of concerns when it comes to safety and equilibrium. Even so, the vehicle attracted attention in public due to its extravagant design and, even though, was gradually developing into a design icon instead of a vehicle. The reason is that it gained reputation due to its brave concept.

5. Messerschmitt KR200

One of the best microcars ever to come out of the automotive world was the Messerschmitt KR200. The car was designed by Fritz Fend and was significantly inspired by aircraft engineering. The vehicle has a recognizable bubble canopy which enclosed the cockpit providing an experience of driving a small aircraft. The 3-wheeled design allows for it to be a very efficient and light machine and the vehicle was built to provide a cheap way of transport following the war.

Aircraft-Inspired Microcar & Design Features:

• Bubble canopy aircraft inspired design
• Lightweight three-wheel microcar layout
• Compact cockpit-style driving position
• Affordable post-war mobility solution

The KR200 was never meant to be more than an inexpensive mode of transport but became a favorite with all people. Its design stems from various previous Messerschmitt bubble cars but over the years performance and ease of driving were enhanced. In spite of its miniature size it still managed to feel quite nippy to drive and earned a reputation for economy and a lack of useless complexity in design. A smart solution to the problems of post-war mobility.

The Messerschmitt KR200 might be obsolete now but it is a symbol of miniature design ingenuity. Proof that the aviation inspired designs of the time could be adapted into practical cars and cars which could both be efficient and offer the latest in space-saving motoring.

6. Heinkel Kabine

The Heinkel Kabine came to market in the microcar surge of the 1950s and is known as a popular example of the “bubble car” trend. A product of Heinkel Flugzeugwerke, it integrated its compact engineering with thoughtful, safety-focused designs.

Even though innovative the Janus was difficult to handle because of its unique weight distribution. Depending on how many passengers the Janus had the car’s center of balance could shift which made the ride occasionally unsafe. Even with that problem the Janus was a workable short-range transporter. Its layout was an advancement of how an interior could be designed. The Zndapp Janus is now remembered as an interesting automotive experiment and was one of the first true concept cars where the designer attempted an unorthodox approach.

8. Amphicar

Amphicar, this dual purpose vehicle was engineered to drive on the roads and then plunge into the sea as a boat. It had its own propulsion to convert from car to boat and then back again which really was one of the most ingenious designs ever conceived for a vehicle. The two separate and highly differing modes that this car could operate on, really did set this unique vehicle apart from the others and was a pure experiment in transport for all mediums, The most unusual design of car ever produced.

Amphibious Design & Functional Features:

• Dual mode car and boat vehicle
• Built-in water propulsion system
• Road and water operation capability
