EV maintenance costs run roughly half of what a gas engine costs to keep running. Hybrids land right in the middle. Gas cars are the most expensive of the three to service over time. That’s not a guess — it’s what AAA’s own vehicle cost data shows when you break maintenance down to cents per mile. But “EV wins” isn’t the whole story. Where those savings show up, and where they quietly disappear, depends a lot on how you drive and how long you keep the car.
What do EV maintenance costs actually look like next to hybrids and gas cars?
Per mile, EVs cost about 5.5 cents to maintain. Hybrids run about 8.9 cents, and gas cars cost about 10.1 cents, according to AAA’s most recent vehicle cost research. Over 15,000 miles a year, that gap turns into hundreds of real dollars.
| Powertrain | Maintenance cost per mile | Estimated cost at 15,000 mi/year |
|---|---|---|
| Gas | $0.101 | ~$1,515 |
| Hybrid | $0.089 | ~$1,335 |
| EV | $0.055 | ~$825 |
That’s roughly $690 a year in favor of an EV over a comparable gas car. It’s about $510 a year over a hybrid. Consumer Reports has found similar patterns. The group estimates that EVs can cut repair and maintenance costs by up to 50% compared to gas vehicles over the life of the car. You can dig deeper into how that plays out over five and ten years of ownership in our full guide on EV total cost of ownership.
Why do gas cars cost the most to maintain?
Gas engines have the most moving parts of the three powertrains, and every one of them wears out on a schedule. Oil changes, spark plugs, timing belts, fuel filters, and exhaust components all need regular attention. Those costs compound as the car ages.
- Oil and filter changes every 5,000–7,500 miles
- Spark plug replacement every 30,000–100,000 miles depending on type
- Timing belt or chain service, often a $500+ job
- Exhaust and emissions system repairs as the car ages past 100,000 miles
None of that goes away with a hybrid, either. A hybrid still carries a full gas engine underneath its electric motor.
Are hybrids really a smart middle ground?
Yes. For most drivers, hybrids offer real maintenance savings without asking you to change how you fuel up. You still get conventional oil changes and engine service. But regenerative braking stretches brake pad life, and the electric motor takes some load off the gas engine.
The tradeoff is that hybrids have two systems to eventually maintain instead of one. That’s part of why hybrids are outselling EVs in 2026 — buyers want lower running costs without giving up gas station convenience. If you’re shopping a specific model, check whether the hybrid premium actually pays off. The Kia Sportage Hybrid is a good example worth running the numbers on.
Where do EV maintenance costs sneak up on you?
EVs skip oil changes, spark plugs, and exhaust repairs entirely. That’s where most of their savings come from. But EVs are heavier than comparable gas cars, and that extra weight wears through tires faster. It’s a cost people rarely budget for.
Battery-related repairs are the other wildcard. AAA notes that the biggest single maintenance cost for both EVs and hybrids is the high-voltage battery. Replacement outside of warranty can run around $5,000. That’s rare on modern EVs with 8-year battery warranties, but it’s worth understanding before you buy. It’s also worth checking what EV-specific tires actually cost, since that’s a far more common expense than battery failure.
So which one should you actually buy?
If you drive more than average and can charge at home, an EV will save you the most on maintenance and fuel over five years. Full stop. If home charging isn’t realistic, or you drive fewer miles, a hybrid captures most of the savings without any lifestyle changes.
I’d only recommend sticking with a straight gas car if you plan to sell before 60,000–70,000 miles. The same goes if you genuinely can’t stomach the upfront price gap. Past that mileage mark, oil changes and belt jobs start adding up fast. The math tips toward electrified options pretty quickly after that.

FAQ
Do EVs really never need oil changes?
Correct — EVs have no engine oil to change since there’s no combustion engine. You’ll still need to service brake fluid, coolant, and cabin air filters on most models. It just happens far less often than on a gas car.
Is hybrid battery replacement a common expense?
No, most hybrid batteries are designed to outlast the rest of the car. Many are backed by 8-year or 100,000-mile warranties. Replacement outside warranty does happen, but it’s the exception rather than the rule.
Do EVs really cost more to insure, offsetting the maintenance savings?
EV insurance premiums do tend to run higher than gas cars. That’s partly because repairs and parts cost more after an accident. It’s worth factoring that into your total cost math alongside the maintenance savings.
Which costs more long-term: a hybrid or a full EV?
A full EV usually wins on total maintenance and fuel costs if you drive a lot of miles and can charge at home. A hybrid can come close, and sometimes wins overall, if your driving is lower-mileage or charging access is limited.
