What is the strongest part of a car?

Answer 1

on unibody vehicles, the "cage" that surrounds the passenger compartment is usually comprised of the strongest steel. these parts would be the a-pillars, b-pillars, c-pillars (d if equippe), rocker panels, and sail panels. the front frame rails that cradle the engine are also very strong, but have built in crush zones that crumple in the event of an accident

Answer 2

The chassis, or frame, is typically considered the strongest part of a car as it provides structural integrity and support for the entire vehicle.
