The Evolution of Messerschmitt Microcars: From KR175 to the TG500 “Tiger”
The name Messerschmitt is widely associated with high-performance German aircraft from the Second World War. However, in the decade after the war, the company also produced some of the most distinctive microcars ever built. These vehicles—small, economical, and often three-wheeled—were created during a period when Germany urgently needed affordable transportation.
Between 1953 and 1964, Messerschmitt and its successor manufacturing partner produced a short but fascinating line of “bubble cars” known collectively as the Kabinenroller (“cabin scooter”). Designed primarily by engineer Fritz Fend, these cars evolved through several models: the Messerschmitt KR175, Messerschmitt KR200, Messerschmitt KR201, and finally the four-wheeled FMR Tg500 sports microcar. Although production lasted barely more than a decade, these unusual vehicles left a lasting mark on automotive history.
Origins: Post-War Germany and the Microcar Movement
After the end of World War II, German aircraft manufacturers were temporarily prohibited from building airplanes. Messerschmitt, which had built famous fighters like the Messerschmitt Me 262, suddenly needed alternative products to keep its factories running.
At the same time, Germany faced a severe shortage of affordable transportation. Traditional automobiles were expensive and fuel was limited. Engineer Fritz Fend recognized this need and proposed a small, lightweight vehicle derived from his earlier mobility scooters for disabled veterans.
Messerschmitt agreed to produce the design, and in 1953 the first Kabinenroller microcar entered production. All Messerschmitt microcars shared several distinctive features:
- Tandem seating (driver in front, passenger behind)
- Bubble canopy reminiscent of fighter aircraft cockpits
- Lightweight monocoque construction
- Small two-stroke engines from Fichtel & Sachs
- Extremely compact dimensions and excellent fuel economy
The Kabinenroller platform ultimately supported four main production vehicles between 1953 and 1964.

The Messerschmitt Microcar Models
1. Messerschmitt KR175 (1953–1955)
The first production Messerschmitt car was the Messerschmitt KR175, introduced in February 1953 at the company’s factory in Regensburg, West Germany.
The model name was derived from “Kabinenroller” (KR) and the approximate engine displacement of 175 cc. The vehicle was essentially a tiny three-wheeled car: two wheels at the front for steering and one driven wheel at the rear.
Key Specifications
- Production years: 1953–1955
- Engine: 173–175 cc single-cylinder two-stroke
- Transmission: 4-speed sequential gearbox
- Layout: Rear mid-engine, rear-wheel drive
- Weight: About 220 kg (485 lb)
- Top speed: roughly 50–55 mph (80–88 km/h)
Approximately 15,000 units were produced during its short production run.
Trim and Body Variants
The KR175 was offered in several configurations:
- Standard canopy coupe (fixed bubble canopy)
- Convertible canopy variant
- Electric-start option in later production
- Italian-built “Mivalino” version produced under license
Early KR175 cars required numerous modifications, with about 70 design updates implemented within the first months of production to improve reliability and usability.
Despite its quirks, the KR175 proved that an ultra-compact car could be practical and affordable.
2. Messerschmitt KR200 (1955–1964)
In 1955, Messerschmitt introduced the improved Messerschmitt KR200, which quickly became the most famous model in the lineup.
Though visually similar to the KR175, the KR200 incorporated numerous engineering improvements and more powerful performance.
Key Specifications
- Production years: 1955–1964
- Engine: 191 cc single-cylinder two-stroke
- Transmission: 4-speed sequential (engine could run in reverse direction for reverse gear)
- Weight: around 230 kg
- Top speed: approximately 56 mph (90 km/h)
- Production: about 41,190 units built
One of the KR200’s most unusual features was its transmission system: the engine could rotate in either direction, meaning the same four gears functioned as forward or reverse depending on engine rotation.
Body Styles and Trim Levels
The KR200 was offered in several distinct versions:
- KR200 Coupe – the standard enclosed bubble canopy model
- KR200 Cabriolet – folding soft-top canopy
- KR200 Sport – performance-oriented version
- KR201 Roadster – fully open, doorless roadster with cut-down bodywork
The KR201 Roadster, technically a derivative of the KR200, emphasized sporty driving and minimal bodywork. It retained the same mechanical components but with a lighter open design.
Record-Setting Performance
The KR200 also achieved several endurance and speed records for small-displacement three-wheel vehicles in the mid-1950s, helping boost the car’s popularity.
Corporate Transition: FMR Takes Over
In 1956, the situation changed for Messerschmitt. The restrictions on German aircraft manufacturing were lifted, allowing the company to return to aviation. As a result, Messerschmitt sold its Regensburg vehicle factory.
Production of the microcars continued under a new company called Fahrzeug‑ und Maschinenbau GmbH Regensburg (commonly abbreviated FMR), created by Fritz Fend and industrial partner Valentin Knott.
Although the KR200 continued to wear Messerschmitt branding for marketing reasons, the vehicles from 1956 onward were technically produced by FMR.
3. Messerschmitt KR201 Roadster (Late 1950s)
The Messerschmitt KR201 was essentially a roadster version of the KR200. It retained the same drivetrain and mechanical structure but featured:
- An open cockpit
- No canopy or doors
- Lightweight bodywork
- A sportier appearance
This variant was marketed primarily as a recreational or sporting vehicle rather than a commuter microcar. Production numbers were relatively small compared to the KR200, making surviving examples rare today.
4. FMR Tg500 “Tiger” (1957/1958–1961)
The final and most powerful vehicle in the Kabinenroller lineage was the FMR Tg500, commonly known as the “Tiger.”
Unlike the earlier three-wheel models, the Tg500 had four wheels, transforming it from a microcar into a compact sports car.
Key Specifications
- Production years: 1958–1961
- Engine: 494 cc two-stroke twin-cylinder
- Transmission: 4-speed manual with reverse
- Layout: Rear-engine, rear-wheel drive
- Top speed: roughly 80 mph (130 km/h)
- Production: approximately 300 units
The Tg500 incorporated significant upgrades:
- Hydraulic brakes
- Larger wheels and improved suspension
- Full rear axle with two wheels
- Higher performance engine
Because of its speed and handling, the Tiger was sometimes used in motorsport competition and was considered one of the fastest microcars ever produced.
However, the Tg500 was also expensive and arrived at a time when traditional small cars were becoming widely available.
Design Characteristics of Messerschmitt Cars
All Messerschmitt microcars shared several unique engineering and design elements.
1. Fighter-Plane Inspired Canopy
The bubble canopy hinged to the side or front, similar to a fighter cockpit. This design maximized visibility and created the iconic “bubble car” appearance.
2. Tandem Seating Layout
Passengers sat directly behind the driver rather than side-by-side, allowing the car to remain extremely narrow.
3. Lightweight Engineering
The monocoque structure minimized weight, contributing to good fuel efficiency and modest performance despite tiny engines.
4. Three-Wheel Configuration
Most models used two wheels at the front and one at the rear. This arrangement reduced mechanical complexity and taxation in some European countries.
Production Numbers and Timeline
Below is a simplified timeline of the Messerschmitt microcar family.
| Model | Production Years | Configuration |
|---|---|---|
| KR175 | 1953–1955 | Three-wheel microcar |
| KR200 | 1955–1964 | Improved three-wheel microcar |
| KR201 | Late 1950s | Open roadster variant |
| Tg500 “Tiger” | 1958–1961 | Four-wheel sports microcar |
Overall Kabinenroller production lasted 1953–1964, with the KR200 accounting for the majority of vehicles produced.
Decline of the Messerschmitt Microcars
By the early 1960s, the European microcar market began to collapse. Several factors contributed:
- Economic recovery in Europe meant buyers could afford larger cars.
- Vehicles such as the Mini and the Volkswagen Beetle offered greater practicality.
- Safety concerns about three-wheel vehicles increased.
Production of the KR200 ended in 1964, marking the end of the Messerschmitt microcar era.
Legacy and Collectability
Today, Messerschmitt microcars are highly collectible classics. Enthusiasts admire them for their:
- Unique aviation-inspired design
