Which Car Has the Cheapest Insurance?

How Insurers Actually Measure Which Car Is “Cheap”

Insurance companies do not estimate a vehicle’s risk from a spec sheet. The Highway Loss Data Institute (HLDI) — an affiliate of the Insurance Institute for Highway Safety (IIHS) — collects claims data from insurers representing more than 85% of the United States private-passenger vehicle market, making it the largest repository of real-world vehicle loss data in the world.^[4] From that data, HLDI calculates two distinct numbers for every model on sale: claim frequency, how often that specific vehicle is involved in a claim, and claim severity, how large the average payout is when a claim happens.^[4]

Auto insurance is not one product but a bundle of six coverages, and a vehicle’s price is built from its performance across all six. Collision coverage pays to repair the insured driver’s own car when they are at fault. Property Damage Liability pays to repair the other driver’s car or property. Comprehensive coverage pays for theft, vandalism, fire, and animal strikes. Personal Injury Protection and Medical Payments coverage pay medical bills for the people inside the insured car, and Bodily Injury liability pays for injuries the insured driver causes to people in other vehicles.^[5] HLDI scores every model against a baseline of 100, representing the average across all passenger vehicles; a score of −40% means that model’s losses run 40% below the national average, and +40% means 40% above it.^[5] The models that consistently win on premium are the ones that post negative scores across nearly every one of those six categories at once, not just one.

Why the Cheapest Car to Buy Is Rarely the Cheapest to Insure

It is a reasonable assumption that the least expensive car on the lot should also be the least expensive to insure. HLDI claims data shows the opposite: subcompact economy cars frequently carry higher insurance premiums than midsize SUVs costing two or three times as much to buy.^[4] The mechanism is physical, not financial. A small, light vehicle has less structural crush space available to absorb a collision’s kinetic energy, so the same impact that a heavier vehicle’s occupants walk away from more often ends in an injury claim for the smaller car’s occupants. Because medical claims and bodily injury payouts are vastly more expensive to an insurer than replacing sheet metal, that elevated injury frequency drives the subcompact’s Personal Injury Protection and Medical Payments premiums up far enough to offset its lower purchase price.

The opposite extreme carries its own penalty, just a smaller one. Full-size pickup trucks and heavy SUVs protect their own occupants exceptionally well — the Ford F-350 posts collision losses 69% below the national average — but that same mass increases the force transferred into whatever they strike, which raises Property Damage Liability claims on the vehicles and property they hit.^[4] Compact and midsize SUVs in the 3,000-to-4,000-pound range sit at the point on this curve where occupant protection is high and outward aggressivity is low, which is exactly the combination that produces the lowest combined premium across every coverage category at once.

The Structural Engineering Behind the Cheapest Models

The Honda CR-V’s position at the top of the ranking traces directly to Honda’s proprietary Advanced Compatibility Engineering (ACE) body structure.^[9] A conventional frame concentrates a frontal crash’s energy into two main side rails; if a heavier vehicle overwhelms those rails, or misses them entirely, the passenger cabin of the smaller car can collapse. The ACE structure instead routes the crash force through an interconnected network of front frame members, spreading it upward into the A-pillars, downward into the floor frames, and outward into the side sills and roof rails — distributing the impact over a much larger share of the vehicle’s structure instead of concentrating it in one place.^[9] That distribution does two things an actuary rewards: it keeps the CR-V’s own cabin intact, which suppresses Personal Injury Protection and Medical Payments claims, and it lowers the aggressivity of the CR-V toward whatever it hits, which suppresses the Bodily Injury and Property Damage Liability claims filed against its driver.

Subaru’s Outback, Forester, and Crosstrek achieve a similar result through a different architecture: the Subaru Global Platform and its Ring-Shaped Reinforcement Frame, which connects the roof, the A/B/C pillars, and the floor into a single continuous structural hoop designed to resist collapsing inward during a severe side impact or rollover.^[11] Both approaches point to the same underlying principle HLDI’s data confirms repeatedly: a vehicle that keeps its own occupants safe while limiting the damage it does to others posts lower losses across every coverage category simultaneously.

The Metallurgy Paradox: Stronger Steel, Pricier Repairs

The structures described above are only possible because of modern automotive steel, and understanding that steel explains a real paradox in the insurance data: the same metal that saves lives is expensive and difficult to repair. Steel strength is measured in megapascals (MPa) of tensile strength — the force per unit area the metal can withstand before it deforms permanently.^[10]

Ultra-High-Strength Steel and Boron-alloyed steel cannot be repaired the way older, softer steel could. Heat destroys the metal’s temper, so a shop cannot use a torch to straighten a bent UHSS panel; any component exposed to heat during an attempted repair must be replaced outright. Parts above roughly 600 MPa cannot be cold-straightened on a frame rack either, because the metal is prone to micro-cracking when bent back into shape — it has to be cut out and replaced with a new, factory-welded part.^[10] Attaching that new part requires specialized resistance spot-welding equipment capable of generating upward of 10,000 amps, rather than the MIG welders used on older, softer steel.^[12]

Insurance actuaries accept this trade-off because the alternative is worse. A $10,000 collision claim to replace a Boron-steel B-pillar is still far cheaper than a six-figure Personal Injury Protection payout for a crushed cabin. The average incurred loss per collision claim nationally has climbed to roughly $7,191, driven in large part by the cost of replacing these advanced materials rather than repairing them — but the models built with the most UHSS also post the lowest bodily injury and medical payments losses, which is why they still come out cheapest to insure overall.^[1]

Crash-Avoidance Technology: Subaru EyeSight as a Case Study

Structural engineering only limits damage after a crash starts. Advanced Driver Assistance Systems (ADAS) are designed to prevent the crash from happening at all, and Subaru’s EyeSight system — standard equipment on the Outback and Forester — is one of the most extensively studied examples in HLDI’s research. Unlike systems built around a bumper-mounted radar unit, EyeSight uses a pair of stereo cameras mounted high inside the windshield, which shields the sensors from the low-speed parking-lot fender-benders that routinely destroy exposed bumper-mounted hardware.^[13]

HLDI’s multi-year analysis found that EyeSight-equipped Subarus saw bodily injury liability claim frequency fall 26% across all driver ages, with the effect even larger for younger drivers.^[13] Isolating claims that resemble pedestrian and bicyclist strikes specifically, HLDI measured a 33% reduction with the first generation of EyeSight and a 41% reduction with the second generation, and a separate 15% reduction in Property Damage Liability claim frequency, consistent with automatic braking preventing rear-end collisions before they happen.^[14] Every one of those avoided claims is a claim the insurer never has to pay, and that saving is what shows up as a lower renewal premium.

Theft Resistance and Federal Motor Vehicle Safety Standard 114

The final major driver of a vehicle’s premium is Comprehensive coverage, and the single largest source of severe Comprehensive losses is whole-vehicle theft. Federal Motor Vehicle Safety Standard 114, “Theft Protection and Rollaway Prevention,” requires that a vehicle’s starting system prevent normal engine activation and forward mobility whenever the key is removed.^[15] Since the late 1990s, the industry standard for meeting that requirement has been the electronic engine immobilizer — a cryptographic transponder in the key that the vehicle’s computer must verify before it will allow fuel or electricity to reach the engine.

Vehicles that lack that technology demonstrate exactly how much it is worth. Certain base-model Hyundai and Kia vehicles built between 2011 and 2021 shipped with a conventional mechanical key ignition instead of an immobilizer to reduce manufacturing cost.^[16] Once that omission became widely known in mid-2020, theft claims for those specific models surged, whole-vehicle theft losses spiked in the Comprehensive coverage category, and premiums for those models rose sharply — in some cases prompting carriers to stop writing new policies on them in high-theft zip codes entirely.^[17] Every model on the cheapest-to-insure list, by contrast, ships with a standard immobilizer, which keeps its Comprehensive-coverage losses near the national baseline and its overall premium correspondingly low.

The Electric Vehicle Nuance

Electric vehicles complicate the ranking in a specific, measurable way: the average cost per claim to repair an EV runs about $5,903, compared with $4,938 for a gas-powered car, largely because technicians must safely isolate and handle high-voltage battery packs and because many EVs use aluminum or reinforced structures to offset battery weight.^[2] Despite that higher repair severity, overall collision and liability losses for EVs frequently run lower than for comparable gas vehicles, because EV drivers tend to file fewer claims and because a floor-mounted battery pack lowers the vehicle’s center of gravity, improving occupant protection in a rollover or side impact.^[2] That combination is why the Chevrolet Bolt posts collision losses 48% below the national average and why the Mini Cooper Electric appears among the ten cheapest vehicles to insure nationwide, at roughly $2,099 a year, despite the higher dollar cost of any single EV repair.

Using This Ranking When Shopping for a Vehicle

Every figure in this report is a national average; an individual quote still depends on the driver’s age, location, driving record, and the specific carrier underwriting the policy. See our companion report on what you need to apply for car insurance for the exact information a carrier will ask for once a specific model is chosen, and request a quote on the exact trim and model year under consideration before treating any national average as a firm number.

Families shopping specifically for a teenage or first-time driver should treat this report as background context rather than a final answer: age and driving experience move the premium far more than model choice alone, and the safest, cheapest-to-insure choices for a new driver are not identical to the cheapest models overall. See our companion report on what car has the cheapest insurance for teenagers for the model-year cutoffs, curb-weight thresholds, and IIHS-recommended vehicle lists specific to that decision.

Buyers considering an older, already-depreciated vehicle from this list should also weigh whether full coverage still makes financial sense at all. See our companion report on whether you need full coverage insurance on a used car for the state Total Loss Threshold math that determines when collision and comprehensive coverage stop paying for themselves.
