Why Power-to-Weight Matters
Power-to-weight ratio is one of the best single metrics for predicting a car's performance potential. Two cars with the same horsepower can have very different performance if one weighs significantly more. Reducing weight by 10% has the same effect as increasing horsepower by 10%.
