Every Mercedes-Benz CLA-Class engine, compared
Picking the right version of the same car often saves more fuel than picking a different car altogether. Yearly cost assumes 12,000 miles at $3.20 a gallon.
| Engine | Combined | City / Highway | Years | Fuel per year |
|---|---|---|---|---|
| Electric | 127 / 124 | 2026–2027 | $305 | |
| 2L 4-cyl Hybrid | 26 / 36 | 2024–2026 | $1,280 | |
| 2L 4-cyl | 23.8 / 34.4 | 2014–2026 | $1,381 |
What that actually costs
Miles per gallon is an abstraction; the fuel bill is not. Here it is in money, at 12,000 miles a year and $3.20 a gallon.
| Measure | Value |
|---|---|
| Cost per mile | $0.082 |
| Fuel per year | $982 |
| Fuel over five years | $4,910 |
| Against other 4-cyl cars | −$530 a year |
| EPA's own estimate | $2,511 a year |
City or highway — who is this car for
The gap between city and highway figures tells you whom the car suits. A wide gap punishes stop-and-start traffic; a narrow one means the car doesn't care where you drive it.
| Measure | Value | Reading |
|---|---|---|
| City | 35.7 mpg | $1,076 a year if you only drive in town |
| Highway | 44.6 mpg | $861 a year if you mostly commute |
| Gap | +8.9 mpg (25%) | Typical for its type |
How the CLA-Class changed over the years

How we count
Fuel-economy figures come from EPA fueleconomy.gov — the same laboratory numbers printed on the window sticker. We don't adjust them; real-world consumption depends on how and where you drive.
What we add is money. Yearly cost assumes 12,000 miles at $3.20 a gallon — change either and the ranking stays, only the size of the bill moves. Cost per mile is the same figure divided out, useful when comparing a commute against a weekend car.
