eTorque is a battery-based system that provides torque assist and regenerative braking for light-duty trucks. The system consists of a 48-volt battery, motor/generator, power inverter module, and belt-driven starter generator (BSG). eTorque is designed to improve fuel economy by up to 8 percent while also providing auxiliary power for accessories such as air conditioning and electric power steering.
The eTorque system will last the lifetime of the vehicle if properly maintained. The batteries are designed to last 10 years or 150,000 miles, whichever comes first. With proper care and maintenance, the BSG should last the lifetime of the vehicle as well.
