PHEVs can save money if you drive within the electric range daily and charge regularly. Short commutes and frequent charging maximize savings, while long highway trips may reduce the financial benefit.
Daily driving distance, charging frequency, local electricity rates, and gas prices have the biggest impact. Driving more miles than your electric range daily reduces savings potential.
Daily charging provides maximum savings by using the cheaper electric mode for most trips. Even partial charging every 2-3 days can provide significant cost benefits compared to gas-only operation.
MPGe (miles per gallon equivalent) measures energy efficiency by converting electricity use to gasoline equivalent. It combines electric and gas efficiency based on your driving pattern and charging habits.
Choose a PHEV if you can charge regularly and drive within electric range daily. Regular hybrids are better for long-distance driving without charging infrastructure or if electricity costs are very high.
City driving with frequent stops favors electric mode efficiency. Highway driving depletes the battery faster and relies more on gas. Short trips under 30 miles typically use only electric power.
Use your actual residential electricity rate from your utility bill, typically between $0.10-$0.25 per kWh. Some utilities offer special EV rates that can be lower during off-peak hours.
