Karsan has begun commercial autonomous passenger service with its Autonomous e-ATAK in the Swedish mountain resort town of Sälen, marking one of the first Level 4 public transportation deployments in a ski tourism setting. The Turkish manufacturer, which develops electric and autonomous commercial vehicles, received passenger transport approval from the Swedish Transport Agency (Transportstyrelsen) on March 9, 2026, following winter testing that began in January 2026. The bus operated for approximately one month during the peak ski season on a 4.8-kilometer route connecting ski resort areas with accommodation points.
Highlights
- Karsan Autonomous e-ATAK received Transportstyrelsen approval on March 9, 2026 after winter testing under heavy snowfall and mixed pedestrian-skier traffic
- Service operates on a 4.8-kilometer route between ski resorts and accommodation in Sälen, Sweden
- Deployment is part of the Sälen–Idre Autonomous Public Transportation Project (SIKTA), led by the Municipality of Malung-Sälen
- Phase two will extend autonomous e-ATAK operations to Idre, another major Swedish winter tourism hub
Winter Conditions Stress-Test the Autonomy Stack
According to Karsan, the Sälen deployment subjected the Autonomous e-ATAK to some of the harshest operating conditions yet documented for a Level 4 public transportation vehicle. The bus ran in shared road environments with constant pedestrian and skier interaction, heavy snowfall, and low-grip winter surfaces. Karsan characterizes the deployment as one of the most comprehensive real-world tests to date for autonomous public transit in mountainous terrain.
The commercial phase followed several months of pre-service testing in traffic and shared-road scenarios. Karsan has not disclosed the automated driving software stack or sensor configuration used on the Sälen e-ATAK, though prior Karsan Autonomous e-ATAK deployments in Stavanger, Norway and at Michigan State University have been automated by ADASTEC.
SIKTA Partnership and Scalable Tourism Model
The Sälen–Idre Autonomous Public Transportation Project (SIKTA) is led by the Municipality of Malung-Sälen in partnership with the Municipality of Älvdalen, Dalarna University, and local businesses. Sweden joins a growing list of Nordic markets — including Norway, which recently approved autonomous bus operations without a safety driver — that are positioning public transport AVs for commercial rather than pilot-scale operation.
Karsan says the second SIKTA phase will extend Autonomous e-ATAK service to Idre, another Swedish winter tourism destination. The route and timeline for the Idre deployment have not been announced.
Executive Perspective
Karsan CEO Okan Baş said: “With this project we have launched in Sälen, we have demonstrated that autonomous mobility can operate safely and seamlessly even in winter tourism regions one of the most challenging use cases for autonomous mobility. This application is strong evidence that autonomous public transportation has moved beyond being a pilot technology and has become an integral part of real life. This new success further solidifies Karsan’s leadership in the field of autonomous mobility.”
What’s Missing
Karsan has not released independently verified data on intervention rates, passenger counts, or operating hours during the commercial month of service, nor has it detailed sensor configuration, automated driving software partner, or any safety driver arrangement used during the commercial phase. Third-party validation of the winter-conditions performance has not been published.
