According to open sources, Konstantin started the Bentley project on tracks, which was called Ultratank, in 2019. The body and interior remained from the luxury sedan, a unit from Toyota was installed in the engine compartment, the transfer case was from a GAZ-66 (an old military passenger truck), the tracks were made to order in Kursk. Investments in the vehicle-constructor were estimated at six million rubles.

The car was tested off-road, in snow, prepared for trips around the city (it was reported that due to its dimensions, a special lowboy was required for delivery to asphalt). The car on tracks accelerated to 50 kilometers per hour, it was planned to increase the maximum speed to 100 kilometers per hour. The last relevant video with the Bentley Ultratank was published on the blogger's platforms in 2023.
