Abstract: The invention relates to a vehicle having a drive train, which comprises at least one first engine and a wheel, wherein a torque can be transmitted from the first engine to the wheel by the drive train, and wherein at least one first unit of the drive train is connected to an interface, by which rapid and simple replaceability of said unit is possible, wherein the interface is designed to be connected to a second unit, which is different from the first unit, wherein both units are designed to store electricity, to convert chemically bound energy into energy of rotation and/or to convert electricity into energy of rotation and/or to convert rotation energy of rotation into electricity.

Abstract: An input device having keys for selecting rearward driving (R), neutral position (N) and forward driving (D), as well as a decrementing control switch (5) and incrementing control switch (4) for manually lowering and raising the gear stage. Starting from the gearbox mode of the input device and the forward driving (ASM) operating state, a tempomat mode (TM) can be adopted by actuating the key (D). The actuation of the operating elements is interpreted in the tempomat mode as a command for the tempomat, it being possible, in particular, for the decrementing and incrementing control switches (4, 5) to be used for lowering or raising the desired speed. A return to the gearbox mode takes place through renewed actuation of the “D” key or actuation of the brake (6).
