Monocoque vs ladder chassis or unibody vs body on frame respectively. These are the two main types of vehicle chassis. The chassis is the frame or skeleton of the vehicle and here are the two most popular types.
Monocoque or Unibody are the terms used to indicate when the body of the vehicle is designed and built to support the weight of the vehicle and any other function of a chassis. This is achieved by strengthening the floor of the vehicle, the pillars and using bracing along various parts of the body.
Ladder Chassis or Body over Frame are the terms used when the body of a vehicle is mounted to a separate frame or chassis. This frame is similar to a ladder in design as two long pieces of steel (approximately the length of the vehicle) are held parallel to each other by shorter pieces running across.
Either chassis should perform the following functions at least at a workable level.
Unibody, body on frame or any type of chassis has to strike a balance between weight/materials used, intended function, vehicle design and cost but the type of chassis used will have certain benefits and ultimately determine the function and character of the vehicle.
Performance - The monocoque is a lighter design which is a plus for fuel efficiency, it has more torsional stiffness and is by far the better chassis for performance oriented vehicle. The heavy nature of the ladder chassis makes it tough and it is much better than the monocoque for carrying heavy loads and towing heavier objects.
Design - A unibody bodyshell is difficult to design, build and modify (platform sharing) when compared to the body on frame but computer assisted design (CAD) has greatly reduced this advantage. Another body can be placed on a ladder chassis but changes have to be made to major parts of the vehicle.
Materials - Unitary bodyshells can be made from a variety of materials steel and steel alloys, aluminium and aluminium alloys and even carbon fiber or combinations of these materials whereas ladder chassis are usually built from steel.
Other Benefits - It is much easier to incorporate crumple zones into a vehicle with a monocoque bodyshell but a vehicle with a ladder chassis is much easier to repair after an accident.
Monocoque chassis are used in most vehicle types and is more suited for everyday, luxury and sport oriented vehicles but the ladder chassis is better suited for commercial and heavy duty work. Debating on monocoque vs ladder chassis will come down to the intended function of the vehicle.

What type of construction is it when the internal body structure of a vehicle is used as its frame a Unibody b Body-frame c Integral or d Body-over-frame?
Unibody
Explain the difference between a separate body chassis and a integral chassis?
The difference is that a separate body chassis consists of the vehicle body and a separate frame which the body is bolted to (sometimes referred to as ladder frame). The integral chassis consists of a single body/frame unit, there is no separating them, they are one part (often referred to as unibody construction).
Does a 1995 Nissan Maxima have a unibody frame?
Yes, the frame is integrated into the body.
What frame is the 1988 camaro on?
It's not on a frame as it's a unibody and it's the F-body platform.

Why Do Jeeps Have A Unibody Frame?
The all do not have a unitized construction. The Jeep Wrangler is body on frame. The reason manufactures went to unitized construction is lower cost. The only jeep that had a unibody was the small Cherokee and that had sub frame assemblies mot true unibody. EVERY other jeep has full frames.
What kind of frame does a 1992 Ford Mercury Capri has?
AnswerIt is either a unitized body with the frame built into the car or it is a body on frame construction. A quick look under the car will tell you which it is.a 91-94 capri has what is called a unibody . go to google and type in unibody they will explain it. ford has used unibody construction since the 1964 mustang . most new cars use this kind of construction.
Is there a difference in the body or frame between the 1999 Mercedes e320 and e430?
There is no difference
What do you mean by chassis?
The chassis is the structural elements of the vehicle. A unibody chassis, (no separate frame) includes everything but bolted on body panels. If the vehicle has a body bolted on a separate frame construction then the chassis is the frame.
What is an advantage of unibody construction over body on frame construction?
it weighs less, contributing to performance and fuel economy
What kind of frame does 1970 chevelle have?
The 1970 chevelle body is mounted on top of a full frame the 1970 chevelle is not a unibody design like the camaro or nova
When the internal body structure of a vehicle is used as a frame it is called?
When the internal body structure of a vehicle is used as a frame, it is called a unibody structure. This design integrates the vehicle's body and frame into a single unit, providing structural strength and reducing weight.
