Methodology & EV Data Sources
How we calculate Lexus RZ 300e charging costs and range data: Our EV specifications, range estimates, and charging cost calculations integrate official federal testing data with current utility rate information.
- Range and efficiency ratings from the US DOE/EPA Fuel Economy Guide (FuelEconomy.gov) — the official source for EPA-rated range, MPGe, and energy consumption for all EVs sold in the US.
- Electricity rate data from EIA Electric Power Monthly — the authoritative federal source for residential electricity prices by state and region.
- Federal EV credit status details from IRS Clean Vehicle Credit (Section 30D) and the DOE EV Tax Credit Eligibility Checker.
- Charging infrastructure data from DOE Alternative Fuels Station Locator (AFDC) — the national database of public EV charging stations.
- Emissions savings calculations use EPA eGRID grid emission factors to accurately measure CO₂ avoided per mile driven in the Lexus RZ 300e vs. average gasoline vehicle.
Authoritative EV and energy data sources:
- FuelEconomy.gov (DOE/EPA) — official EPA range, MPGe, and efficiency ratings
- EIA Electric Power Monthly — residential electricity prices by state
- DOE Alternative Fuels Data Center — EV charging infrastructure and incentives
- EPA eGRID — grid carbon intensity for emissions calculations
- DOE Office of Energy Efficiency — Electric Vehicles — federal EV research and policy
- IRS Clean Vehicle Credit (Section 30D) — current federal EV credit status and eligibility rules
EV Disclaimer: Range estimates are based on EPA-rated figures under standard test conditions. Real-world range varies by driving speed, temperature, HVAC use, cargo load, and terrain. Charging costs use average utility rates — actual costs depend on your electricity plan and time-of-use rates. Federal credit status changes with acquisition date, MSRP limits, income thresholds, purchase method, and vehicle eligibility — verify with IRS.gov before purchase.
