The cars most commonly in fatal crashes are small cars, sports cars and muscle cars, according to the latest data from the Insurance Institute for Highway Safety (IIHS). Its July 2026 report ranks 2023 models by driver deaths from 2021 to 2024. The average was 37 driver deaths per million registered vehicle years. The worst small car ran more than four times that rate. At Humphrey & Ballard Law, we see how vehicle size shapes injuries in Atlanta crashes. Here is what the new numbers show and what they mean after a wreck.
How IIHS Measures the Deadliest Cars
IIHS counts how many drivers of each model died in crashes, then adjusts for how many of those vehicles are on the road. The result is deaths per million registered vehicle years. One registered vehicle year is one vehicle on the road for one year. This lets a rare sports car be compared fairly with a best-selling sedan. IIHS also tracks a second number: how many people die in other vehicles hit by each model. That other-driver rate shows which vehicles are most dangerous to everyone else on the road. You can read the full IIHS driver death rate report on its website.
Cars With the Highest Driver Death Rates
The Kia Rio had the highest driver death rate in the latest report, at 170 per million registered vehicle years. That is more than four times the all-model average of 37. IIHS found that more than half of the top-ranked models were small cars, sports cars or muscle cars. Small cars have less structure to absorb a crash. Powerful sports and muscle cars are often driven fast, which raises crash severity.
| IIHS measure (2023 models, deaths 2021 to 2024) | Rate per million registered vehicle years |
|---|---|
| Average driver death rate, all models | 37 |
| Highest driver death rate (Kia Rio) | 170 |
| Average other-driver death rate | 53 |
| Highest other-driver death rate (Ram 3500 crew cab long bed 4WD) | 204 |
| Models with zero driver deaths | 6 models |
Vehicles With Zero Driver Deaths
Six models had a driver death rate of zero: the Audi Q7 4WD, BMW X7 4WD, Chevrolet Tahoe 4WD, Mercedes-Benz GLB-Class 4WD, Mercedes-Benz GLE-Class 2WD and Toyota Tundra CrewMax 4WD. Most are large or midsize SUVs and pickups. Their size and weight help protect the people inside. A zero rate does not mean these vehicles never crashed. It means no driver of that model died during the study period.
Why Big Vehicles Are Safer Inside but Riskier for Others
Weight works both ways. IIHS notes that even the safest small cars do not fare well in crashes with large pickups and heavy SUVs. On the other-driver list, 10 of the top 20 models were large or very large pickups, several of them heavy-duty versions. The Ram 3500 crew cab long bed 4WD had the highest rate, at 204. When a heavy pickup or commercial truck hits a small car, the people in the small car take most of the force.
What Vehicle Size Means for an Injury Claim in Georgia
The car you drove does not change who caused the crash. Fault turns on driver conduct, such as speeding, following too closely or running a red light. Size often shapes the injuries, though. People in small cars hit by large vehicles are more likely to suffer traumatic brain injuries, fractures and spinal injuries. Those injuries raise medical costs and lost income, which affects the value of a claim. Georgia uses modified comparative fault under O.C.G.A. § 51-12-33. Your recovery drops if you share blame, and it ends if you are 50 percent or more at fault. A defect claim against an automaker is a separate path that needs expert analysis.
Frequently Asked Questions
What car has the highest fatality rate?
The Kia Rio. In the IIHS report released in July 2026, it had 170 driver deaths per million registered vehicle years for 2023 models. The average across all models was 37.
Which car brands get in the most fatal crashes?
IIHS ranks individual models, not brands. The highest driver death rates came mostly from small cars, sports cars and muscle cars. Heavy-duty pickups ranked highest for deaths of people in the other vehicle.
Can I sue if a bigger vehicle hit my small car in Atlanta?
Yes, if the other driver was at fault. The size of your car does not reduce their responsibility. Georgia generally gives you two years from the crash to file a lawsuit under O.C.G.A. § 9-3-33.
