You can now use all of Motoristo’s tools and calculators directly from our new app on the Google Play Store (iOS coming soon).
The app lets you save and load configurations, and even works offline, perfect for when you're out in the garage or on the go.
Understanding the different parameters
Power
The amount of horse power the vehicle has.
Weight
The vehicle weight in KG.
What is the power-to-weight ratio?
The power-to-weight ratio is the amount of power a vehicle has in relation to it's weight.
A vehicle with a higher power-to-weight ratio is likely to accelerate faster than a vehicle with a lower ratio. This is often why you find motorsports enthusiasts going through the process of weight removal on their cars.
This therefore provides us a simple, rudimentary method of comparing how vehicles might fair with each other.
How to calculate the power-to-weight ratio
The formula to calculate an the power-to-weight ratio can be seen below, this is what we use in the calculator above.
Power per 1000KG = (HP / Weight in KG) × 1000
