Buying Considerations

Understanding Your Efficiency Metrics

MPGe vs. MPG: MPGe measures efficiency while the battery is charged. Once the electric range is exhausted, the vehicle operates as a standard hybrid, and the "Gas-Only MPG" becomes the primary efficiency metric.
Tax Incentives: While federal tax credits for many PHEVs have changed, some models may still qualify for incentives based on battery size and manufacturing location. You can check current eligibility at FuelEconomy.gov.
