PHEV Fuel Economy & Electric-Gas Driving Ratio Calculator (MPGe)
Calculate your Plug-in Hybrid Electric Vehicle's (PHEV) true combined fuel economy, electric driving share percentage (EV vs ICE mode), and EPA MPGe efficiency based on daily commute distance and battery range.
Electric Driving Share Percentage
Calculator Inputs
Electric Driving Share Percentage
Real Blended Gas Consumption (L/100km)
Daily Gas Fuel Consumed (Liters)
Electric Distance

Calculation Methodology
Electric km = min(Daily Distance, Electric Range). Gas km = max(0, Daily Distance - Electric Range). Electric Share % = (Electric km / Daily Distance) * 100. Blended Gas Consumption = (Gas km * Hybrid Mode L/100km) / Daily Distance.
