Description

The Messerschmitt KR 175, introduced in 1953, was a unique three-wheeled microcar designed by German aircraft manufacturer Messerschmitt and engineer Fritz Fend. Created in the wake of World War II when economic conditions called for affordable, fuel-efficient personal transportation, the KR 175 became a symbol of the post-war microcar boom.

The KR 175 was powered by a 173 cc single-cylinder, two-stroke engine producing around 9 horsepower, allowing it to reach speeds of up to 50 mph (80 km/h). Power was delivered to the single rear wheel through a 4-speed sequential transmission. While modest by modern standards, the KR 175’s lightweight design and streamlined body allowed for surprisingly nimble performance in city driving.

The car’s design was heavily influenced by Messerschmitt’s expertise in aircraft, resulting in an enclosed, bubble-like canopy that resembled a fighter cockpit. This canopy opened sideways to allow access, and the two-seat arrangement was tandem, with the driver seated in front of the passenger. The small size and three-wheel configuration made it highly maneuverable and well-suited for narrow urban streets, though it required some care to handle safely.

Inside, the KR 175 offered basic seating with minimal controls, focused purely on functionality. The interior was sparse, with a simple steering bar and few amenities, keeping costs and weight low. Despite its unconventional design, the KR 175 found success in Europe, where it was popular for short-distance commuting.

The Messerschmitt KR 175 remains a notable microcar for its unique design, efficient use of resources, and connection to Messerschmitt’s aviation heritage. It stands as a lasting example of innovative engineering in response to economic constraints and has become a collectible classic in automotive history.
