What is HP to Weight Ratio?
HP to weight ratio determines how much horsepower is available per unit of vehicle weight. It’s a critical performance metric for cars, bikes, aircraft, and even electric scooters. This ratio directly correlates with acceleration capability and overall performance.
Why It Matters:
- Higher ratio = faster acceleration and better performance
- Used in drag racing, tuning, and track day performance analysis
- Helps compare vehicles of different sizes fairly
- Essential for motorsport classifications and regulations
Performance Categories:
| HP to Weight Ratio | Category | Typical Examples |
|---|---|---|
| < 0.05 HP/kg | Low Performance | Economy cars, trucks |
| 0.05–0.10 HP/kg | Average Car | Family sedans, SUVs |
| 0.10–0.15 HP/kg | Sports Car | Performance cars, hot hatches |
| 0.15–0.25 HP/kg | Superbike | Motorcycles, supercars |
| > 0.25 HP/kg | Race Spec | Formula cars, race bikes |
