Self Propelled car help?

How can I make a self propelled car?
I am using a rubber band type source for power. I cannot apply any kind of force to the car. I also have to reach 60 meters.

Can anyone help me?
If this helps, I am using a structure similar to a 2 liter V8 bottle.

Sorry, but I'm not alllowed to use any sort of launching device.

Hi. Traction is your biggest worry. Tire (wheel) spin will cause a loss of potential energy. Use tacky rubber for the OD of the wheels.
