Avopyöräiset

Avopyöräiset is a Finnish term that translates to "open-wheeled" in English. It generally refers to vehicles with exposed wheels, meaning there are no fenders or body panels covering the sides of the wheels. This design is common in various forms of motorsport, particularly racing.

The most prominent examples of avopyöräiset vehicles are formula racing cars, such as those found in Formula 1, IndyCar, and Formula 2. These cars are characterized by their low-slung chassis, powerful engines, and the distinct sight of their wheels protruding from the sides. The open-wheel design contributes to reduced aerodynamic drag compared to vehicles with enclosed wheels, which is crucial for achieving high speeds in racing.

Beyond professional racing, the term can also be applied to certain types of go-karts, drag racing cars, and other specialized vehicles where unimpeded wheel movement and minimal aerodynamic obstruction are prioritized. The exposed nature of the wheels also allows for easier access for maintenance and tire changes, a practical consideration in competitive environments. While offering performance advantages, the open-wheel design also presents specific safety considerations, particularly regarding wheel-to-wheel contact and debris thrown by the tires.
