One that is sleek, one coat of paint should do it, to help smooth out areas a file couldn't. Don't take too much off the front end, because the car will fly upwards when you shoot it off.
light weight and friction
very thin And low to the ground
a cube
it would be a ktm car
What is the distance used in a CO2 car competition What is the distance used in a CO2 car competition
A small skinny car is best. you can even cut out peices of wood in the shape to make it lighter.
something light and aerodynamic would be best
the co2
Petrol cars produce CO2 as a combustion by-product, so it might be said that whatever the fastest car in the world is the fastest CO2 car. There are no cars powered by CO2 - obviously - as any chemical reaction starting with CO2 needs energy to produce another substance. There might be a car somewhere powered by compressed CO2, but this will stop moving when it runs out of pressure. Consequently the fastest CO2 car is a parked car.
Aerodynamics of the car, the size of the wheels, the weight of the car, and the size of the CO2 cartridge.
usually, a bullet shaped design would work better if made of balsa wood
Doesn't the driver ( and any passengers ) in the car emit CO2 as well, so you are not comparing like with like.You must compare CO2 from Car, driver and passengers with CO2 emitted by cyclist to be more accurate.You will need to divide the CO2 for car driver and passenger by number of occupants of car to get CO2 per person per journey
