...as oppose to bolting suspension and steering parts straight to the chassis?

Sorry, thought I'd keep this topic separate from my wheel alignment one for ease of reference

Subframe is an efficient way of adding strength where it's needed also makes it a damn sight easier to build...

 .......

because cars now are a monocoque construction & don't have a chassis

Landrover never got that memo

thanks al

Monocoque is a car without a chassis, ie all one piece.
Chassis is just that... a frame on which everything else is mounted.

Watch a series or two of American Hot Rod, and all will be clearer...

Examples...
Omega is a monocoque design.
Rover P4 has a separate chassis.
F body Camaro/Firebird/Trans Am has a monocoque shell which ends at the firewall. Everything infront of the doors is on a chassis bolted to the firewall.

Some cars, like the Disco3 have a full chassis, with a monocoque shell on top, which is why they're so bloody heavy

This is a chassis ....... there are other variations



a modern car has the rigidity built into the various box sections & pressings including the way the windscreen is glued in ie monocoque

Ooops! a bit big!

Thanks Al. im still to check those out .....

but for the purpose of the subframe question its either the chassis or monocoque that the subframe bolts to?

it bolts to the monocoque on a bit we call the chassis legs ...... but it's not really a chassis, just a term that's still used 

[Webby the Bear]

Thanks Andy.

so in very simple form (for me lol) the chassis is a frame in which the car is built on i.e. body attached, suspension attached etc etc and the monocoque is an entire ''body'' that is strong when bolted together thus not needing the ''frame''?
