Next-Generation Gear Lubricants for Electric Vehicles

Published October 2026

Electric vehicles (EVs) are redefining drivetrain design, placing new demands on gear lubrication. High-speed, compact gearboxes operate under continuous loads and elevated temperatures, requiring lubricants to reduce friction, manage heat and ensure electrical compatibility. A key challenge is balancing efficiency and durability; lower-viscosity fluids improve energy efficiency but reduce film thickness, which increases wear risk.
