Big cars and SUVs offer greater occupant safety than small cars in collisions.
Large cars and SUVs generally provide superior occupant protection compared to small cars during collisions, primarily due to their greater mass and extended crumple zones.
The claim is specific, empirical, and testable. Multiple retrieved studies (e.g., papers 3, 6, 8, 9, and 10) consistently demonstrate that larger and heavier vehicles, such as SUVs, offer better crash outcomes and occupant protection due to mass ratios and deformation space, whereas smaller vehicles experience higher deceleration and injury risks. No papers refute this established automotive safety finding.

Evaluates vehicle-to-vehicle compatibility in side impacts, confirming that vehicle mass and geometric profile heavily influence occupant intrusion and injury potential.

Demonstrates via simulation models that mass ratio is a crucial aggressivity parameter in head-on collisions, placing lighter vehicles at a significant disadvantage.

Shows through a comprehensive analysis of national crash databases that vehicle type and weight are more important predictors of survival in head-on crashes than official safety ratings.

Explains that small vehicles possess less deformation space, leading to higher vehicle and occupant deceleration during frontal collisions and thus greater injury risk.
Takanobu Fujimura. Simulation and Optimization Analysis of Small Vehicle Deceleration to Reduce Occupant Injury at Frontal Collision. 2015. https://doi.org/10.4271/2015-32-0705
Confirms that smaller vehicles suffer from restricted deformation space which inherently makes achieving crashworthiness and managing kinetic energy more difficult than in larger vehicles.
