Meaning and Definition
A type of differential in a vehicle's drivetrain that allows wheels to rotate at different speeds while limiting the maximum speed difference between them to prevent wheel spin.
A mechanical or electronic system designed to improve traction by automatically transferring power from a slipping wheel to the wheel with more grip. In figurative use, it can describe any system or mechanism that allows for controlled, limited variation between components or outcomes.
Dialectal Variation
British vs American Usage
Differences
No significant semantic difference, but the term is slightly more common in US automotive marketing and publications. Abbreviations like 'LSD' are used in both regions.
Connotations
Connotes performance, improved handling, and off-road capability. In US car culture, it is often associated with performance vehicles and motorsports.
Frequency
Marginally higher frequency in American English due to the larger scale of the automotive aftermarket and motorsports media.

- Confusing it with a fully 'locking differential'. A locking differential mechanically locks both wheels together, while an LSD allows some difference. Incorrect pluralization: 'limited-slips differentials' (correct: 'limited-slip differentials').
FAQ
Frequently Asked Questions
No. A limited-slip differential is a purely mechanical (or electro-mechanical) component in the axle. Traction control is an electronic system that uses brakes and engine power reduction to prevent wheel spin.
Not necessarily, but many performance-oriented AWD systems use them on one or more axles to further enhance torque vectoring and handling dynamics.
Yes, especially clutch-type LSDs. The clutches can wear over time, reducing their effectiveness. Some types require specific lubricants.
Torsen is a portmanteau of 'Torque-Sensing'. It is a specific brand and design of gear-based limited-slip differential known for its smooth operation and reliability.
A type of differential in a vehicle's drivetrain that allows wheels to rotate at different speeds while limiting the maximum speed difference between them to prevent wheel spin.
Limited-slip differential is usually technical / automotive in register.
Limited-slip differential: in British English it is pronounced /ˌlɪm.ɪ.tɪd slɪp ˌdɪf.əˈren.ʃəl/, and in American English it is pronounced /ˌlɪm.ɪ.t̬ɪd slɪp ˌdɪf.əˈren.ʃəl/. Tap the audio buttons above to hear it.

Learning
Memory Aids
Mnemonic
Think of it as a differential with 'limited permission to slip' – it allows wheels to turn at different speeds for cornering, but limits the slip that causes one wheel to spin uselessly on ice or gravel.
Conceptual Metaphor
A NEGOTIATOR OF TRACTION: It mediates between the conflicting needs of allowing different wheel speeds (for turning) and applying equal power (for grip), making a compromise for optimal performance.
