How to calculate horsepower per liter
This calculator finds horsepower per liter by dividing total horsepower by engine displacement in liters — a common way to compare engine performance density across different engine sizes.
How the calculation works
HP per liter = Horsepower ÷ Engine liters.
Example
300 hp from a 3.0L engine: 300÷3.0 = 100 hp/liter.

Pro Tips for Horsepower per Liter
- 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 horsepower-per-liter figures than naturally aspirated engines of similar design.
Common Horsepower per Liter Mistakes to Avoid
- Comparing horsepower-per-liter figures between naturally aspirated and turbocharged engines as if they should perform similarly, when forced induction changes the comparison.
