Most "eco-friendly" car services ask you to take the claim on faith. We don't. Below is the emissions and cost math for electric versus gas premium transportation in San Diego — every figure linked to its primary source (U.S. EPA, fueleconomy.gov, U.S. EIA, the manufacturers). Where the honest answer is "it depends," we say so.
Elite Green Transportation is San Diego's only 100% electric licensed premium car service — BMW i7 & Cadillac Escalade IQ, zero tailpipe emissions, flat-rate.
Tailpipe emissions: A gallon of gasoline burned produces 8,887 g of CO2, and the average gas passenger vehicle emits ~400 g CO2/mile (EPA). A battery-electric vehicle emits zero at the tailpipe (EPA). EGT's fleet is 100% electric, so every ride is zero-tailpipe.
The honest caveat: generating the electricity isn't emission-free, and that varies by region — but even counting the grid, the EPA finds an EV is typically responsible for lower total greenhouse gases than the average new gas car, and California runs one of the cleanest grids in the U.S.
Energy cost: at California prices, the BMW i7 costs about 13¢/mile in electricity vs about 36¢/mile in gas for a comparable full-size luxury SUV — computed from EPA ratings and current state prices (shown below). EGT charges a flat rate either way; the point is the ride is clean and quiet, not metered.
EGT operates two battery-electric vehicles. These are the manufacturer- and EPA-published numbers, linked at the bottom of this page:
| Vehicle | Type | Usable battery | Range | Tailpipe CO2 |
|---|---|---|---|---|
| BMW i7 xDrive60 | Full-size electric luxury sedan (up to 2 passengers in EGT service) | 101.7 kWh | Up to ~318 mi EPA (varies with wheel size) | 0 g/mi |
| Cadillac Escalade IQ | Full-size electric luxury SUV (up to 5 passengers) | ~205 kWh | ~460 mi (Cadillac estimate) | 0 g/mi |
BMW i7 battery and range per InsideEVs' EPA overview and BMW USA. Escalade IQ battery and range per Cadillac and Wikipedia. The Escalade IQ is heavy enough that a standard EPA window-sticker range isn't required, so we cite Cadillac's estimate as an estimate — not an EPA figure.
The U.S. EPA publishes the core numbers, and they are not in dispute:
Applied to comparable luxury vehicles, using their EPA combined fuel economy:
| Vehicle (comparable gas model) | EPA combined | Tailpipe CO2/mile |
|---|---|---|
| Gas Cadillac Escalade (4WD) | 16 mpg | ~555 g/mi |
| Gas BMW 760i xDrive (V8) | 20 mpg | ~444 g/mi |
| EGT — BMW i7 / Escalade IQ (electric) | — | 0 g/mi tailpipe |
CO2/mile = 8,887 g/gal ÷ mpg, computed by EGT from EPA figures. Gas Escalade 16 mpg combined and gas BMW 760i 20 mpg combined per fueleconomy.gov and Edmunds. Per-gallon and per-mile CO2 per the U.S. EPA.
This is the fuel-energy cost to move the vehicle one mile — not total cost of ownership, just energy. Inputs are current California prices, linked below; the math is shown so you can check it.
| Vehicle | Efficiency (EPA) | California price | Energy cost/mile |
|---|---|---|---|
| Gas Cadillac Escalade | 16 mpg | ~$5.80/gal | ~36¢/mi |
| Gas BMW 760i | 20 mpg | ~$5.80/gal | ~29¢/mi |
| BMW i7 (electric) | ~0.379 kWh/mi | ~33.75¢/kWh | ~13¢/mi |
| Cadillac Escalade IQ (electric) | ~0.48 kWh/mi | ~33.75¢/kWh | ~16¢/mi |
Gas cost/mile = price/gal ÷ mpg; electric cost/mile = kWh/mi × price/kWh; computed by EGT. California gasoline average (~$5.80/gal, mid-June 2026) per AAA and the California Energy Commission. California average residential electricity rate (~33.75¢/kWh, 2026) per the U.S. EIA. i7 efficiency (~379 Wh/mi incl. charging losses, 89 MPGe) per InsideEVs/EPA.

EGT bills a flat rate, not by the mile or the kilowatt-hour, so this table isn't your invoice. It's the underlying reality: an electric premium ride is cheaper to operate and cleaner to run, which is part of how EGT holds flat, no-surge pricing.
Beyond the spreadsheet, the electric difference is something you feel: no engine noise or vibration, instant smooth torque, and no exhaust — in a full-size luxury cabin. For a San Diego airport run, a Hotel del Coronado arrival, or an executive transfer, that's a measurably better ride and a smaller footprint, with no trade-off you have to apologize for.
And it's verifiable in another way: EGT operates under California TCP #0046494-A with $1.5M commercial liability, confirms a named driver in advance (no substitutions), and prices every trip as a locked flat rate with no surge. Native American-owned (Choctaw Nation) and woman-owned, owner-answered 24/7.
San Diego's only 100% electric licensed premium car service. Zero tailpipe, no surge, named driver confirmed in advance.
