Merriam-Webster's Collegiate Dictionary defines inertia as: “a property of matter by which it remains at rest or in uniform motion in the same straight line unless acted upon by some external force.”
What this means for a racecar: The greater the mass of the car, the more energy required to get the stationary car moving. If two cars use the same amount of propulsive energy, the car with the lower mass will accelerate faster.
Surface friction and fluid friction also come into play as the inertia of the stationary car is overcome. If the masses of two cars are equal, then the winner will likely be the car with the least friction.
Because all CO2 racecars use the same amount of propulsive energy (the escaping gas from a CO2 cartridge), it is important to reduce all factors that contribute to inertia.
