Motor and Wheels mounting location of the robot

Hi Guys,

I was designing an off-road robot car, and I came across a question when deciding which DC motor was suitable for the robot.
Is the motor and wheels’ location affect the output?

(Please don’t mind the drawing style, the image above is used to explain the condition below)
Let’s say if:

  • I place the motors closer to the left & right side of the robot or further, or
  • I put the wheels closer or further away from the front and the back.

Will there be any difference? If so, what will be the formulas to support these statements?

Noted, The motor and wheels were connected and mounted inside the robot structure.
