Yes, airplanes do have a motor (according to what I know). There are many place in a commercial aircraft that have a motor. The engines also have a motor in them to turn the fan or propellers.
According to studies, airplanes are 9 times faster than cars. It is because they are powered with greater thrust by propellers and jet engines.
