2m powering 2 wheels or 1m on each wheel?

I am just wondering in terms of power that can be utilized from motors.

Is it better to have 2m powering two wheels together or have each motor directly powering each wheel individual.

I was just thinking that when motors reach there torque limit they just stop spinning so it would be better to have 2 motors because then they can keep each other spinning and in tern transfer more energy into motion.

What are your thoughts on this?
Should my drive have each wheel powered individual or 2 motors together on each side?


linking the two wheels on each side of your drive is better because if one wheel has less traction or gets raised off the ground at any point, you still get your full 2 motors of power on each side getting transferred into motion.
