Electronic Limited-Slip Differential vs Mechanical Differential in Performance Cars
A mechanical limited-slip differential uses gears or clutch packs to limit wheelspin automatically, with no computer involved. An electronic limited-slip differential, or eLSD, uses an actuator and software to control those same clutches, so it can react faster and vary its locking by situation. The mechanical unit is simpler, cheaper and easier to repair. The electronic one is more precise and can be tuned through drive modes. One warning for buyers: some cars sold with
