AVL Concept Turbohybrid Mild Hybrid System Approaches Full Hybrid Fuel Savings at Lower Cost; Improved Driveability

Green Car Congress

Comparison of Fuel Consumption, Fun to Drive and System Cost of the different powertrain concepts. full hybrid (power-split) system delivered a 36% compared to the baseline. However, the system cost of the Turbohybrid was 150% that of the baseline, while the system cost of the full hybrid was more than 300% that of the baseline.
