ELECTRAAX

High-efficiency, lightweight electric drive axle for medium-duty trucks and buses

ELECTRAAX

ELECTRAAX, created in partnership with Driventic, is a high-efficiency electric drive axle engineered to increase range or reduce battery requirements for Class 6-7 medium-duty vehicles. This ePowertrain design integrates the axle, gearbox, motor, and inverter into a single optimized system to reduce weight, unlock packing space, and elevate overall vehicle capability. ELECTRAAX is available in capacities up to 23,000 pounds.

ELECTRAAX

Features and Benefits

INTEGRATED ePOWERTRAIN

  • Axle, gearbox, motor and inverter integrated into a single optimized system
  • The application-specific architecture allows ELECTRAAX to deliver up to 94% system efficiency
