The invention relates to an electric steering and drive system for a vehicle with two tracks and with skid steering, comprising: - drive elements for crawlers or for wheels; - a transfer gearbox; and - two drive shafts, a first drive shaft being torque-transmittingly connected or connectable to a drive element of one track and to a first electric machine and a second drive shaft being torque-transmittingly connected or connectable to a drive element of the other track and to a second electric machine, and both drive shafts being torque-transmittingly connected to the transfer gearbox. The transfer gearbox has two planetary gear systems, which more particularly are arranged so as to be mirror-symmetrical and each have the following elements: a sun gear, a planet carrier which carries planet gears, and a ring gear. Each of two identical first elements of the two planetary gear systems is torque-transmittingly connected to one of the two drive shafts. Two identical second elements of the two planetary gear systems are connected to each other for conjoint rotation. A third element of one planetary gearbox is torque-transmittingly connected to a third electric machine, and an identical third element of the other planetary gearbox is fixed to a housing.
