The Cadillac Lyriq is rated 90.5 MPGe (98.3 city, 82.3 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 37.2 kWh per 100 miles, so 12,000 miles a year costs about $759 at $0.17 a kWh. The EPA's own annual figure for it is $838.

|---|---|---|---|---|
| Electric | 98.3 / 82.3 | 2023–2026 | $759 |
What that actually costs
MPGe is an abstraction; the electricity bill is not. At 12,000 miles a year the Cadillac Lyriq draws about 4464 kWh, which at $0.17 comes to the figures below.
| Measure | Value |
|---|---|
| Energy use | 37.2 kWh per 100 miles |
| Cost per mile | $0.063 |
| Charging per year | $759 |
| Charging over five years | $3,795 |
| Against other Electric cars | +$78 a year |

City or highway — who is this car for
The Cadillac Lyriq is one of the cars that does better in town than out of it — 98.3 in the city against 82.3 on the highway. That is $76 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 | 98.3 MPGe | $700 a year if you only drive in town |
| Highway | 82.3 MPGe | $834 a year if you mostly commute |
| Gap | -16 MPGe (-16%) | Reversed — it does better in town than on the open road |
How the Lyriq changed over the years
The Lyriq peaked in 2026 at 92 MPGe (100 city, 83 highway) and was at its thirstiest in 2024 at 89 — 3 MPGe apart, or $26 a year in fuel between buying one year and the other. The 2026 car does 92. Jumps usually mark a new generation or a new engine; dips often mean a heavier body or added all-wheel drive.
| Model year | Combined MPGe | City / Highway | Versions offered | Charging per year |
|---|---|---|---|---|
| 2026 | 100 / 83 | 1 | $747 | |
| 2025 | 100 / 83 | 1 | $747 | |
| 2024 | 96 / 81 | 1 | $773 | |
| 2023 | 97 / 82 | 1 | $773 |

Frequently asked questions
What is the Cadillac Lyriq rated at?
90.5 MPGe combined on average — 98.3 in the city and 82.3 on the highway, per EPA ratings across 2023–2026. 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 Lyriq cost to charge per year?
About $759 at 12,000 miles and $0.17 a kilowatt-hour — roughly $3,795 over five years, or 0.063 dollars a mile.
Which Lyriq version is the most efficient?
The Electric at 90.5 MPGe.
Is the Lyriq 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 Lyriq 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 Lyriq is $838 against the $759 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.
