Testiajossa

Testiajossa is a Finnish term used to describe an annual automotive testing event and public demonstration held in Finland. The event blends a trade show, test-drive sessions, and technical presentations. It is organized by a cooperative of car manufacturers, research institutes, and municipal authorities and attracts participants from Finland and other Nordic countries.

The name combines Finnish words 'testi' (test) and 'ajossa' (in motion / on the move), conveying hands-on testing and active demonstration.

The concept originated in the early 2010s as a regional showcase focusing on new car models and safety features. It expanded rapidly and by the mid-2010s had national status, with dedicated track facilities and synchronized city tours. In recent years, the event has included electric and autonomous vehicle demonstrations, data-collection sessions, and student competitions.

The format typically includes test drives on closed circuits, manufacturer booths, technical talks, and live interviews. It serves as a platform for evaluating user experience and performance under controlled conditions, while researchers collect data on vehicle dynamics, energy efficiency, and safety features. The event also contributes to local economies through tourism and media coverage.

Critics argue about environmental impact, safety, and the potential for encouraging excessive driving; organizers emphasize safety protocols and environmental measures such as noise limits and emission-conscious track use.
