Power & Torque Converter

The power–torque link

Power (kW) = torque (Nm) × RPM ÷ 9549. At the wheels, acceleration follows the torque curve; peak power tells you top-end potential.

• 1 ch = 0.7355 kW
• 1 hp (imperial) = 0.7457 kW
• 1 Nm = 0.7376 lb-ft
• Diesel engines make peak torque at low RPM; petrol at high RPM
