How Parallel Hybrids Work. Unlike series hybrid drivetrains (where only the electric motor can drive the wheels and the gasoline engine really only serves as its backup generator), a parallel drivetrain can put power to the pavement through the electric motor or the gas engine directly. An onboard computer will determine which is best for the given set of circumstances and make …

This hybrid configuration is the power hybrid. The typical engine downsizing for fuel economy would be replacing the engine by an engine 25 to 30% smaller. In most cases a 3-cylinder engine can be used. Depending on the battery size and the strategy this economy hybrid can be used as charge sustaining or as plug-in.

Parallel Hybrid. A parallel hybrid is propelled by both an internal combustion engine (ICE) and an electric motor connected to a mechanical transmission. Power distribution between the engine and the motor is varied so both run in their optimum operating region as much as possible. There is no separate generator in a parallel hybrid.
