Force equals mass multiplied by acceleration. This is why manufacturers and motorsport teams from around the world work tirelessly to reduce the weight of their cars. The lower the weight of the car, the more power they can get out of the entire package.
Modern manufacturing technologies have been developed to help reduce the weight of performance cars. The most famous being the adoption of carbon fiber. What makes carbon fiber so special is that it helps reduce weight without sacrificing strength. This makes it a more premium option for automakers instead of just adding in plastic parts
