How to calculate vehicle power density
This calculator finds vehicle power density by dividing horsepower by engine displacement in liters — a common way to compare engine performance efficiency across different engine sizes.
How the calculation works
Power density = Horsepower ÷ Engine displacement.
Example
350 hp from a 3.5L engine: 350÷3.5 = 100 hp/liter.
Frequently asked questions

Pro Tips for Vehicle Power Density
- This figure lets you compare how efficiently different engines extract power from their displacement, regardless of overall engine size.
- Forced induction (turbocharging/supercharging) generally allows higher power-density figures than naturally aspirated engines of similar design and displacement.
Common Vehicle Power Density Mistakes to Avoid
- Comparing power density between naturally aspirated and turbocharged/supercharged engines as if similar figures should be expected, when forced induction changes the comparison significantly.
