A direct drive system for an electric car contains: a body (10) and four wheels (11, 12, 13, 14), each of the four wheels (11, 12, 13, 14) including a suspension system (111, 121, 131, 141), a wheel shaft (112, 122, 132, 142), and a driving motor (31, 32, 33, 34) mounted on the suspension system (111, 121, 131, 141). An output shaft (311, 321, 331, 341) of the driving motor (31, 32, 33, 34) is rotatably connected with the wheel shaft (112, 122, 132, 142) of each of the four wheels (11, 12, 13, 14), such that the driving motor (31, 32, 33, 34) independently drives each of the four wheels (11, 12, 13, 14) to rotate. The body (10) includes a control system (20), and the control system (20) has at least one rotation module rotation module (21), an acceleration module (22), and a brake module (23), and the control system (20) is coupled with each of four driving motors (31, 32, 33, 34) to transmit control signals and output signals among the four driving motors (31, 32, 33, 34) and the control system (20). Thereby, the control system (20) controls the four wheels (11, 12, 13, 14) by using the four driving motors (31, 32, 33, 34) to reduce power loss and consumption and to enhance driving durability of the electric car.
