Are you sure you mean the 'A-Frame', or do you mean the 'A-Pillar'?
The frame of the car supports the door pillars and the roof. It supports the roof on two or three pillars depending on whether the car is a two door or a four door.
Immediately after the hood (bonnet), the A-Pillar supports the hinges for the front doors and the windshield (windscreen). The B-Pillar supports the pin that secures the front door locks and the hinges for the rear doors (if fitted). The C-Pillar supports the pin that secures the the rear door locks (if fitted) and the rear window. Each pillar is identified by the side on which it is found (driver side / passenger side) and the the pillar location: ex. Driver's A-Pillar or Passenger B-Pillar.
there is no steal frame- its called a sub frame its not like the old cars or trucks

a shassy is spelled chassis a chassis is the frame that cars are built on most modern cars do not have a chassis,they have a sub frame pickups have a chassis an example would be this if you removed the cab and bed from a pickup you would be left with a frame sitting on suspension and wheels ,with engine and gearbox this frame is the chassis
Almost all cars built today are built on, what is called, a unibody chassis. This incorporates the frame and body into one unit. You could call it a shell. There are still some cars using the body on frame method of production. Almost all trucks are body on frame.
No
they use computerized tires that calibrate the tork and airflow of the cars frame.
***every vehicle has a frame if it didnt it would fall a part*** Not entirely true..... in the early 80s almost all automakers started making cars with Uni-bodys- meaning that the frame was built into the car. while trucks and SUVs have a true frame because the body can be lifted off and it is still a rolling chassis so yeah is some shape or form all vehicles have a frame however there are just different kinds!
The term chassis means the frame plus the "running gear" like engine, transmission, drive shaft, differential, and suspension. That's what we meant when describing older cars that actually had a full frame. Since a lot of new cars are now unibody construction, you could call the front portion of frame which connects to the rest of the body an "engine chassis". Or, if you will, a frame work which supports the engine.
No, they're 2 totally different cars
this is the modern form of construction made in all cars and lighter commercial vehicles
more than the cars worth
