A vehicle drive apparatus including a speed change mechanism, a first and second motor-generators, and a microprocessor. The microprocessor is configured to perform controlling the speed change mechanism, the first motor-generator and the second motor-generator so as to switch a speed range to a low-speed range, operate the first motor-generator as a motor and operate the second motor-generator as a generator when a vehicle speed is equal to or greater than a predetermined vehicle speed and an acceleration instruction is detected, and so as to switch the speed range to a high-speed range, operate the first motor-generator as a generator and operate the second motor-generator as a motor when the vehicle speed is equal to or greater than the predetermined vehicle speed and a deceleration instruction or a termination instruction of an acceleration is detected.
