Next-Generation Gear Lubricants for Electric Vehicles Special Report

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.

Tribology Opportunities for Enhancing America's Energy Efficiency

Surfaces in interacting motion are at the foundation of the critical energy-efficiency properties of friction, lubrication and wear, and these are found throughout all energy systems with moving parts. Tribology, a branch of engineering, is relatively unmapped and uncharted for energy technologies in recent times; not since the 1980s has any comprehensive study been conducted in the United States (U.S.) to assess the impact of tribology and potential benefits of tribology research across energy technologies.
