Vehicle with a pressure tank device

The device has two cylindrical pressure tank sections (1, 2) which are partially arranged under front seats of a motor vehicle at an angle (alpha) of about 10 to 170 degrees with respect to each other, where the tank sections define a T-shaped continuous tank volume. An access device (3) for the continuous tank volume is arranged at one of the tank sections. One of the tank sections is arranged under a rear seat of the vehicle along a transverse direction of the motor vehicle. The other tank section is arranged along a longitudinal direction of the vehicle.
