Calculate Your Power-to-Weight Ratio

Your Power-to-Weight Ratio:

0.00

Performance Level HP/lb HP/kg
Economy Car 0.03 – 0.05 0.07 – 0.11
Sports Car 0.08 – 0.12 0.18 – 0.26
Supercar 0.15 – 0.25 0.33 – 0.55
Formula 1 0.50+ 1.10+

Understanding Power-to-Weight Ratios

What is a Good Power-to-Weight Ratio?

The power-to-weight ratio measures how many units of power are available for each unit of weight. Higher ratios mean better acceleration and performance.

Why This Matters for Performance

  • Acceleration: Directly impacts 0-60 mph times
  • Track Performance: Affects cornering speeds and braking distances
  • Towing Capacity: Influences how well a vehicle can handle heavy loads

How to Improve Your Ratio

  1. Reduce Weight: Carbon fiber parts, lighter wheels, remove unnecessary items
  2. Increase Power: Turbocharging, engine tuning, exhaust upgrades
  3. Both: Best results come from doing both simultaneously

Examples

Vehicle Weight Power HP/lb HP/kg
Toyota Camry 3,300 lbs 203 HP 0.061 0.135
Ford Mustang GT 3,800 lbs 450 HP 0.118 0.261
Porsche 911 Turbo 3,600 lbs 640 HP 0.178 0.392
Bugatti Chiron 4,400 lbs 1,500 HP 0.341 0.752
