Power-to-Weight Ratio Chart: Best Cars Ranked (2025)

How We Calculated These Figures

All P/W ratios in this chart use manufacturer-stated peak power (at the crank) divided by kerb weight (vehicle ready to drive, no passengers or cargo, full fluids). Figures are based on base-model specs unless noted.

Power has been converted to kW where manufacturer figures were in hp. Use the car P/W calculator to check any car not listed here.

Key Takeaways

Kerb weight matters as much as power. A light sports car at 0.20 kW/kg will feel faster than a heavier car at 0.22 kW/kg if the lighter car has better aero, balance, and traction.
EVs are heavy. Battery packs add significant mass — even a Tesla Model S Plaid at 0.35 kW/kg carries nearly 1,000 kg more than a comparable petrol hypercar.
The lightweights punch above their weight. The Aston Martin Valkyrie (0.86 kW/kg) and Koenigsegg Jesko (0.78 kW/kg) achieve supercar P/W numbers that a similarly-powered heavier car can’t match.
Hot hatches are surprisingly close to sports cars. The Honda Civic Type R at 0.16 kW/kg is not far behind many sports cars — and it has four seats and a boot.

Calculate Your Own Car’s P/W

Use the car power-to-weight ratio calculator to enter your exact power and weight figures. The calculator supports kW, hp, and metric horsepowers for power, and kilograms, pounds, and tonnes for weight — with instant results in kW/kg or hp/lb.
