The Cadillac Celestiq is rated 81 MPGe (84 city, 77 highway) — that is not petrol economy but the distance it covers on 33.7 kWh, the energy held in one gallon. Drawn from a socket it needs 41.6 kWh per 100 miles, so 12,000 miles a year costs about $849 at $0.17 a kWh. The EPA's own annual figure for it is $950.

City or highway — who is this car for
The Cadillac Celestiq is one of the cars that does better in town than out of it — 84 in the city against 77 on the highway. That is $42 a year in favour of the commuter stuck in traffic, and it usually means a hybrid drivetrain recovering energy every time you brake.
| Measure | Value | Reading |
|---|---|---|
| City | 84 MPGe | $818 a year if you only drive in town |
| Highway | 77 MPGe | $894 a year if you mostly commute |
| Gap | -7 MPGe (-8%) | Reversed — it does better in town than on the open road |

Frequently asked questions
What is the Cadillac Celestiq rated at?
81 MPGe combined on average — 84 in the city and 77 on the highway, per EPA ratings across 2025–2026. MPGe is distance covered on 33.7 kWh, the energy in a gallon of petrol — the car itself takes none.
How much does a Cadillac Celestiq cost to charge per year?
About $849 at 12,000 miles and $0.17 a kilowatt-hour — roughly $4,245 over five years, or 0.071 dollars a mile.
Which Celestiq version is the most efficient?
The Electric at 81 MPGe.
Is the Celestiq efficient compared with similar cars?
Against other Electric cars it sits below the average of 101 MPGe, computed across 426 ratings.
Are these real-world Celestiq figures?
No — they are EPA laboratory ratings, the same ones printed on the window sticker, and EPA's own annual fuel estimate for the Cadillac Celestiq is $950 against the $849 we compute at 12,000 miles. Expect a little worse in practice: the spread between the city and highway figures is smaller than the spread between two drivers of the same one.
