The formula to calculate the Horsepower Per Liter (HPPL) is:
\[ \text{HPPL} = \frac{\text{HP}}{\text{V}} \]
Where:
Let's say the horsepower (HP) is 300 and the engine displacement (V) is 2.5 liters. Using the formula:
\[ \text{HPPL} = \frac{300}{2.5} = 120 \, \text{HP/L} \]
So, the Horsepower Per Liter (HPPL) is 120 HP/L.
