Abstract

A two-track multi-axle motor vehicle including at least two fuel tanks in which a fuel for producing driving energy for a vehicle drive unit can be stored under high pressure of the order of magnitude of 300 bar and more is provide. Each tank includes a safety valve device having a temperature-sensitive element monitoring only a partial region of the tank surface. The safety valve device allows at least a partial quantity of the stored fuel to escape from the respective tank at a higher temperature, which can occur, for example, in the case of a fire. The temperature-sensitive elements of at least two tanks are arranged here in such a manner that the distance between a left-side wheel (RL) of that vehicle axle, in the vicinity of which the at least two fuel tanks are arranged in the vehicle, and the temperature-sensitive element closest to the left-side wheel (RL) does not significantly differ from the distance of the other of the two temperature-sensitive elements from the right-side wheel (RR) of the vehicle axle.
