Analysis of the Fuel Economy Benefit of Drivetrain Hybridization

Research output: Contribution to conferencePaper


Parallel- and series-configured hybrid vehicles likely feasible in the next decade are defined and evaluated using NREL's flexible ADVISOR (ADvanced VehIcle SimulatOR). Fuel economies of these two diesel-powered hybrid vehicles are compared to a comparable-technology diesel-powered internal-combustion-engine vehicle. Sensitivities of these fuel economies to various vehicle and componentparameters are determined and differences among them are explained. The fuel economy of the parallel hybrid defined here is 24% better than the internal-combustion-engine vehicle and 4% better than the series hybrid.
