The EPA prints a five-year fuel cost comparison on every new car sticker: what you save, or spend, against an average vehicle. Across 8,903 models from 2020 onwards, the number is negative far more often than not.
| Five-year fuel comparison | Models | |
|---|---|---|
| Costs MORE than average | 6,421 | 72% |
| Saves money | 2,482 | 28% |
| Market average | −$3,423 |
The average isn't the median
If "average vehicle" meant the middle of the market, half the cars would land on each side. Instead 72% are worse than it.
The benchmark is a fixed reference figure rather than a running median of what's on sale, and the market has drifted heavier and thirstier than it. Which means the comparison flatters nothing — most new cars are shown spending money relative to a standard almost nobody meets.
The spread is larger than the price of a car
| Brand | Five-year fuel vs average | |
|---|---|---|
| Lucid | +$7,684 | 100% of models save |
| Tesla | +$7,542 | |
| Rivian | +$6,035 | |
| Hyundai | +$1,882 | 67% save |
| Aston Martin | −$11,421 | 0% save |
| Ferrari | −$12,707 | |
| Lamborghini | −$17,335 |
The extremes: a Bugatti Chiron at −$31,750 over five years, against hydrogen models like the Toyota Mirai at +$11,000. That's a $42,750 range — more than a new mid-market car costs outright.
Where the figure misleads
Hydrogen tops the table because of how it's counted. The Mirai and Nexo score +$11,000 partly because fuel costs are calculated on manufacturer-provided free-fuel arrangements. Hydrogen is not free, and stations barely exist outside California.
Electricity costs vary enormously. The EPA uses a national average rate. Charging at home overnight in one state and at a public rapid charger in another produce completely different real numbers.
It's fuel only. Insurance, tyres, depreciation and repairs aren't in it — and on the brands at the bottom of this table, fuel is not the expensive part of ownership.
How to use it properly
Compare within a segment, not against the benchmark. The useful question is whether this crossover costs more to fuel than that crossover, not how either compares to a fixed reference.
Use your own mileage. The figure assumes 15,000 miles a year. If you drive 8,000, halve it — and we found actual mileage varies 5.5x by model.
Check the fuel grade separately. A premium requirement adds around $500 a year, which is where turbo engines quietly lose their advantage.
Pull the original sticker for a used car. It carries these figures for the exact vehicle as built — a window sticker lookup by VIN retrieves it, and a VIN check confirms the engine it left the factory with.
Frequently asked questions
What does the five-year fuel savings figure on a window sticker mean?
It compares the car's fuel cost over five years against an average vehicle. For 6,421 of 8,903 models from 2020 onwards — 72% — the figure is negative, meaning the car costs more to run than the benchmark.
Why do most cars cost more than the average vehicle?
The benchmark is a fixed reference rather than a running median of what's on sale, and the market has drifted heavier and thirstier than it. So the comparison shows most new cars spending money against a standard few meet.
Which brands save the most on fuel?
Lucid at +$7,684 over five years with 100% of models saving, Tesla at +$7,542 and Rivian at +$6,035. At the other end Lamborghini is −$17,335 and the Bugatti Chiron reaches −$31,750.
Is the EPA fuel cost estimate reliable?
It's fuel only — no insurance, tyres, depreciation or repairs — and it assumes 15,000 miles a year at national average energy prices. Hydrogen models score unusually well partly because free-fuel arrangements are counted.
