The dual-motor electric drivetrain has every chance of upending nearly 100 years of mechanical limited-slip differential development. Will sports cars stop taking LSD?

Torsen differentials are torque-biasing limited slips, which use parallel-axis helical gears, instead of clutches to build friction internally, which ultimately prevents slip and provides traction.

A viscous LSD uses a fluid that engages the clutch discs as it heats up under load. A torque-sensing (Torsen) LSD uses gears that are gradually meshed together as input torque increases.

Even if one wheel is suspended and slips, it can quickly limit the slip effectively. Additionally, the stock AT-pattern tires ...
