The comparison is designed to show what changed when you adjust miles or charging price, without presenting a synthetic checkout total.
RENTAL EVIDENCE
Observed three-day trip prices
Current comparisons require fresh three-day quotes across supported pickup dates, enough listings in both powertrain cohorts, and verified classification coverage. Missing evidence is shown as collecting or unavailable.
ENERGY EVIDENCE
EPA identity + EIA prices
Year, make, and base model must join exactly—or through a reviewed alias—to official FuelEconomy.gov records. Ambiguous trims remain an interval rather than a guessed efficiency.
USER SCENARIO
Adjust miles and electricity price
Enter the distance you expect to drive and, if useful, your own charging price. The result is an energy scenario, not an included-mileage, charging-network, or fuel-purchase claim.
BOUNDARY
Descriptive, not causal
The study does not claim that powertrain causes a rental-price gap. Fleet mix, vehicle class, trim, and listing differences remain possible explanations.
What the study can and cannot answer
Does it compare final checkout totals?
No. Observed rental evidence and estimated trip energy are displayed separately. Taxes, protection, optional charges, delivery, mileage limits, and charging-network prices must be confirmed independently.
Does it use a generic EV efficiency?
No. The evidence gate requires exact or reviewed official vehicle identity. If official trims are ambiguous, Carconomics shows an interval or withholds the estimate.
Is the Luxury snapshot currently updating?
Luxury collection is currently paused by owner decision. The last verified snapshot may remain available, staleness is disclosed as a pause, and no new source calls are made.
Evidence boundary: This is an adjustable comparison built from observed rentals and official efficiency and energy-price inputs. It is not a forecast, booking guarantee, or claim that one powertrain is always cheaper. Read the energy methodology.
