What is a chassis in a car?

a cars chassis is underneath and keeps the body, suspension and wheels all attached together. if the chassis wasn't there the car would flop about and eventually either crash or fall apart. Daniel from tda

a car chassis is a frame on which the car is built

wheels suspension cab and body are all attached to the chassis

some vehicles have what is called a sub frame or sub chassis

the this means from the firewall forward there is some chassis attached to the body of the vehicle

the strength in these vehicle is built into the body itself

this makes the vehicle lighter and cheaper to build but not as stout as a full chassis in thhe event of a wreck
