What causes torque steer in front-wheel-drive vehicles and how can it be reduced?

Torque steer is the tendency of FWD vehicles to pull to one side under hard acceleration, caused by unequal drive shaft lengths and angles creating different reactions, unequal compliances in suspension/steering, and power-induced changes in suspension geometry. Solutions include equal-length half shafts with intermediate shaft, high-stiffness suspension bushings, careful steering geometry design, limited-slip differentials, and electronic torque vectoring. Some premium FWD vehicles achieve near-zero torque steer through comprehensive design.
