Researchers at Togliatti State University have developed an electric tracked snowmobile named Rezvy, engineered to perform a range of tasks in extreme winter conditions. The entire assembly, claimed to be unique within Russia, is planned to use domestically sourced automotive components. The project was disclosed through the national initiative “Science and Universities” under the Ministry of Education and Science of Russia. This update comes from the project office responsible for the initiative, ensuring confirmation of the scope and potential impact of the snowmobile in both research and practical applications.
The foldable tracked platform is powered by electric traction and is capable of travelling about 30 kilometers per single charge. To extend its operational reach, engineers equipped Rezvy with a range extender. A compact internal combustion engine acts as a generator when battery levels fall below a threshold of 20 percent. This setup pushes the potential range by roughly 70 additional kilometers, expanding the vehicle’s utility in remote or challenging terrains.
Denis Pavlov, head of the Department of Energy Machines and Control Systems at the TSU Institute of Mechanical Engineering, explained that the team faced a significant design challenge. The goal was to integrate a hybrid propulsion system into a small, foldable snowmobile body while optimizing space for the electric drive. The team selected market-ready components to house the drive unit and opted for rechargeable electrochemical cells with the right balance of power, weight, and dimensions. An initial electrochemical element sourced from a Chinese manufacturer was used during early development, but a Russian alternative from a neighboring regional producer was identified as a viable substitute.

Rezvy is designed as a collapsible structure where each module can be handled by a single person. Assembly requires about seven minutes, and the snowmobile is built to support payloads of up to 150 kilograms. The design also accommodates a detachable sled with the same weight capacity, enabling flexible configurations for ecotourism or rescue missions. In practical terms, this means the craft could be deployed to evacuate people or deliver essential supplies to hard-to-reach areas. A small platform at the rear serves as a mounting base for a compact emergency quadcopter, expanding its potential roles in search and rescue operations.

Project leaders noted that the prototype is complete and operational, with the possibility of moving it to full production on a future manufacturing line. Sergei Peteraitis, vice-rector for scientific and innovative activities at TSU, stated that the team plans to file a patent for the useful model in the coming weeks. These statements were shared with socialbites.ca and reflect the organization’s confidence in the technology and its potential to scale beyond the lab setting.

A trial batch of the versatile hybrid caterpillar snowmobile is slated for production before year-end, signaling a transition from experimental concept to a market-ready product. The broader context of Russia’s efforts in developing advanced power systems and mobile platforms for extreme environments continues to grow, with Rezvy standing as a notable example of collaboration between university research and national science policy.
