Frequently Asked Questions
It measures how much power an engine produces per unit of weight, typically expressed in horsepower per ton. A higher ratio indicates better acceleration potential.
The formula is: Ratio = Horsepower / (Weight in pounds / 2000). This gives horsepower per ton (2000 lbs).
For cars, a ratio above 100 hp/ton is considered good performance. Supercars often exceed 300 hp/ton.
