Comments.Text: How that can be done depends heavily on the design of the car, so no general instructions exists. I simple cases, and very generally it's something like: add a gear to an axle driven by the motor, add another axle with a gear that connects to the first, and goes from that point to the back axle and transfer power to that. If there's a differential on the back axle, that's probably where you want to deliver power.

Comments.Text: While @Henriksupportsthecommunity provided some generic details I find this question rather broad. Please edit it to ask some specific question you are facing with your 4WD implementation. One advise - XL has high torque, so brace everything as much as possible not to damage your gears and axles.

  I have a single XL motor and I would like to make my small car a 4WD one.
  
  Currently, it is just front-wheel drive.
  
  Any good instructions on transmitting power to rear wheels as well?
