Make the car more aerodynamic, make it weigh less, and put a bigger solar panel on it.
Do you mean go faster? All things being equal, a 3-wheeled solar car would have a lower rolling resistance compared to a 4-wheeled solar car. It would be more energy efficient, and therefore able to go faster. A 4-wheeled solar car is inherently more stable.
You would apply force to the accelerator to make the car go faster.
The pedal in the car you push to go faster is the accelerator pedal.
make it go faster
To make a co2 car go faster, make the body streamlined. Keep the weight down and make sure that the axles are smooth.
Faster, no. Smoother, yes.
Metal
destroy it
get a steeper hill
you need to get a batterie
Put less wood on it...
It would make it go faster.
