Torque

High torque at low engine speed makes a car feel strong when pulling away or overtaking. Torque at the wheels is multiplied by the gear ratios. Turbocharged engines often deliver near-maximum torque over a broad speed range, which makes them feel relaxed in everyday driving.

Combustion pressure pushes the pistons, and the crankshaft converts that force into rotation. Torque varies with engine speed.

Torque figures help compare engines for towing and everyday driving. Bolt torque, in contrast, is the tightening force specified for fasteners. Electric motors deliver strong torque from standstill, which explains their quick acceleration.
