More Power allows (among other things):
  • Faster acceleration (at your chosen speed)
  • Faster top-speed gearing (at your chosen acceleration)
  • More Motor Loading = More Output Torque (at your chosen speed)
  • Less Current Draw (at a given loading)
If you understand the concept of "Power" you will understand immediately the various benefits multiple motors will provide you. Research this concept (check out a physics textbook, talk to a physics teacher, talk to a mechanical engineer, etc) and you'll be all set. This is one of those FUNDAMENTAL concepts for drivetrain design.

Honestly,
I'm floored by the number of people who design FIRST drivetrains with seemingly no knowledge of this concept.

Regards,
John
