torque

I do not dare appreciate your question but I shall try to understand it and give an explanation.

If you use a front wheel drive you apply on the front wheels an active torque which can be limited by the wheel adherence to ground and which moves the car. This torque is also limited by the car weight part coming on the front wheels. In same case the rear wheels being free do not transmit a torque but generate due to the rolling resistance of ground contact a passive torque which has to be less than the transmission capability of front drive. This resistance is also proportional to the part of car weight coming on the rear.

In a 4 x 4 all wheels are active and push the car via the adherence force on the ground. All weight is actively used.

Do you need more explanations? Did I rightly understand your question? If not please let me know what is still your need.

a bsolutely answered thank you sorry about the way i asked little foggy this morning

Torque is the force that turns the wheels. In a front wheel drive car torque is applied to the FRONT wheels and this is what moves the car. The rear wheels just follow along, no torque there. And remember... no question is ever stupid.
