- AAA (American Automobile Association)’s 2026 Your Driving Costs study prices gas medium-sedan (four-cylinder) maintenance at $1,827 a year at 15,000 miles.
- A V6 medium SUV (Sport Utility Vehicle) runs $1,829 a year in the same study, almost identical to the sedan figure.
- The hybrid version of that same sedan runs $1,619 a year, about $1,040 less over five years than the four-cylinder sedan.
- Hybrid medium SUVs actually cost more to maintain than their gas counterparts in AAA’s data: $1,902 a year versus $1,829.
- Diesel passenger vehicles are left out of this comparison. No authoritative five-year dataset exists for them right now.
Over five years and 75,000 miles, AAA’s 2026 data puts four-cylinder sedan maintenance at $9,135, V6 SUV maintenance at $9,145, and hybrid sedan maintenance at $8,095.

AAA’s 2026 Your Driving Costs study prices five years of upkeep for three common powertrains. A four-cylinder sedan runs about $9,135, and a V6 medium SUV runs about $9,145, nearly identical.
A hybrid version of that same sedan runs about $8,095, roughly $1,040 lower.
Those figures come from a named, published study, not a guess. The sections below show what it covers, where the powertrains split apart, and why one engine type was left out.
What AAA’s Five-Year Maintenance Cost Figure Actually Measures
AAA publishes Your Driving Costs every year, pricing ownership for the top-selling models in each vehicle category. The 2026 edition, released in September, covers five vehicle classes at the sedan and SUV level plus pickups, each priced at 15,000 miles a year.
The maintenance line isn’t a survey of real owners reporting what they spent. It’s modeled from manufacturer-specified maintenance schedules, retail parts and labor pricing, an extended-warranty allowance, and one set of replacement tires, averaged across the top-selling 2026 models in each category.
That matters for three reasons. The sample is small, five models per category. AAA groups vehicles by class, not by engine: “Medium Sedan” and “Medium SUV” are size categories, not cylinder counts.
A five-year figure assumes flat costs, when real bills climb as a vehicle ages past where AAA stops measuring. YourAutoOptions has already priced the 100,000 to 150,000 mile repair window, and it runs higher than this five-year study.
Four-Cylinder vs. V6: The Gap Is Smaller Than You Think
AAA’s current medium-sedan lineup, cars like the Honda Accord and Hyundai Sonata, is almost entirely four-cylinder in gas trim. That category’s gas maintenance figure is $1,827 a year, or $9,135 over five years.
The medium-SUV category, think Toyota Highlander and Jeep Grand Cherokee, still skews toward six-cylinder engines in gas trims. A few top sellers now use a turbocharged four-cylinder instead. Its gas maintenance figure is $1,829 a year, or $9,145 over five years, a two-dollar annual gap.
The bigger cost gap between these two isn’t maintenance. It shows up in fuel, insurance, and depreciation, all running higher for the SUV.
Where Hybrids Save, and Where They Don’t
The hybrid version of AAA’s medium sedan runs $1,619 a year in maintenance, about $1,040 less than the gas version over five years. Regenerative braking is the main reason. Hybrids lean on the electric motor to slow the car, so brake pads and rotors last longer and get replaced less often.
That pattern doesn’t hold everywhere. In AAA’s medium-SUV category, the hybrid actually costs more to maintain than the gas version: $1,902 a year versus $1,829.
A separate Consumer Reports analysis found battery-electric and plug-in hybrid vehicles run about half the per-mile maintenance cost of gas-only vehicles over a lifetime. That is a similar pattern to AAA’s conventional-hybrid figure above, just measured a different way.
AAA’s five-year window also stops short of the one hybrid-specific cost that worries owners most. A hybrid battery pack is a wear item, and replacing one after high mileage is a real bill that this study’s 75,000-mile ceiling doesn’t reach. YourAutoOptions has already broken down what a hybrid battery replacement costs after 100,000 miles, and it’s worth reading before assuming a hybrid’s lower routine maintenance tells the whole story.
Why Diesel Isn’t in This Comparison
AAA’s 2026 study doesn’t track a diesel category at all, and neither does any other maintenance dataset built for ordinary car buyers. Diesel passenger cars and light SUVs have mostly disappeared from American showrooms. What’s left runs almost entirely in heavy-duty pickup trucks, a different vehicle with a different duty cycle and its own separate cost structure.
Diesel upkeep does run higher for real reasons. Diesel oil and filters cost more, and many diesels need periodic DEF (Diesel Exhaust Fluid) top-offs plus emissions-system service that gas and hybrid engines don’t have.
But without a named dataset measuring that cost over five years for a comparable passenger vehicle, this article isn’t going to invent a number. Better to say the figure doesn’t exist yet than to publish one that isn’t real.
The Worked Example: Same Five Years, Three Powertrains
Say a driver named Marcus puts 15,000 miles a year on his car and plans to keep it five years. He wants to know what that looks like in maintenance alone, across three vehicle types: a four-cylinder sedan, a V6 SUV, and the hybrid version of that sedan.
Using AAA’s 2026 annual maintenance figures:
- Four-cylinder sedan: $1,827 a year × 5 years = $9,135
- V6 SUV: $1,829 a year × 5 years = $9,145
- Hybrid sedan: $1,619 a year × 5 years = $8,095
The hybrid sedan saves Marcus $9,135 minus $8,095, or $1,040, against the four-cylinder sedan over five years. Against the V6 SUV, the hybrid saves $9,145 minus $8,095, or $1,050. Spread over 60 months, that’s about $17 to $18 a month in maintenance alone, before fuel savings are even counted.
| Powertrain (AAA 2026 category) | Annual Maintenance (15,000 mi/yr) | 5-Year Maintenance Total | Best for |
|---|---|---|---|
| Four-cylinder sedan (Medium Sedan, gas) | $1,827 | $9,135 | Sedan buyers who want the lowest routine-maintenance bill |
| V6 SUV (Medium SUV, gas) | $1,829 | $9,145 | Buyers who need SUV space or towing and will accept near-identical maintenance cost to the sedan |
| Hybrid sedan (Medium Sedan, hybrid) | $1,619 | $8,095 | Sedan buyers who want the lowest five-year maintenance total of the three |
| Diesel passenger vehicle | Not tracked by AAA | No reliable national figure available | Not comparable here; see “Why Diesel Isn’t in This Comparison” below |
Frequently asked questions
Does a four-cylinder engine really cost less to maintain than a V6? Not by much, based on AAA’s 2026 data. A four-cylinder medium sedan runs $1,827 a year in maintenance versus $1,829 for a V6 medium SUV, a two-dollar gap. The bigger ownership-cost differences between those two vehicles show up in fuel and insurance, not maintenance.
Why do hybrid SUVs sometimes cost more to maintain than gas SUVs? AAA’s 2026 figures show the hybrid medium SUV at $1,902 a year versus $1,829 for its gas counterpart. Hybrid sedans save on brake wear from regenerative braking, but that pattern doesn’t carry over to every hybrid SUV in AAA’s sample of top-selling models.
What exactly does AAA’s maintenance figure include? It covers manufacturer-specified routine maintenance parts and labor, an extended-warranty allowance, wear-and-tear repairs, and one set of replacement tires. Figures are priced at retail and averaged across the top five 2026 models in each vehicle category, not a survey of real owner spending.
Why isn’t diesel included in this five-year comparison? Diesel passenger cars and light SUVs are now rare in the American market, and no major dataset tracks their five-year maintenance cost the way AAA tracks gas and hybrid models. Rather than estimate a number with no source behind it, this comparison leaves diesel out.
Does driving more or fewer miles a year change these numbers? Yes. AAA’s figures here assume 15,000 miles a year. Its underlying data also covers 10,000 and 20,000-mile-a-year drivers, and maintenance costs scale up or down with mileage since more driving means more scheduled service intervals and faster tire wear.
