Practice question

How does a limited-slip differential (LSD) improve vehicle performance compared to a standard open differential?

  1. An LSD disconnects the drive wheels to save fuel when driving straight.
  2. An LSD limits the speed difference between the drive wheels so more usable torque can reach the wheel with better traction.
  3. An LSD automatically shifts the transmission into overdrive.
  4. An LSD locks the steering wheel in place.

Answer: B — An LSD limits the speed difference between the drive wheels so more usable torque can reach the wheel with better traction.
