- • 200 lb-ft = 271.2 Nm (typical midsize sedan)
- • 300 lb-ft = 406.7 Nm (typical V6 engine)
- • 400 lb-ft = 542.3 Nm (typical V8 engine)
- • 500 lb-ft = 677.9 Nm (high-performance engine)
- • 700 lb-ft = 948.8 Nm (heavy-duty truck/supercar)
- • 1000+ lb-ft = 1355+ Nm (electric vehicles/hypercars)
Understanding Torque
Torque is a measure of rotational force that an engine can produce. It represents the twisting force that drives a vehicle forward and is particularly important for acceleration, towing, and climbing. Different regions use different units to measure torque, with pound-feet (lb-ft) common in the US and Newton-meters (Nm) used in most other countries.
Benefits:
- • Determines acceleration capability, especially from low RPM
- • Critical for towing and heavy-load applications
- • Provides better "seat-of-pants" feel during acceleration
- • Important for off-road and climbing performance
- • Key factor in drivetrain component selection
Important Considerations:
- • Peak torque typically available at lower RPMs than peak horsepower
- • Diesel engines generally produce more torque than gasoline engines
- • Turbocharged and supercharged engines can produce significantly more torque
- • Torque at low RPMs is important for everyday drivability
- • Electric motors produce maximum torque from 0 RPM
