It has the engine in the front and the transaxle (gearbox+differential etc.) 
in the back, these are connected by a "solid" torque tube which is basically a 
large steel tube in which the drive shaft runs from clutch(M)/drive plate(A)
back to to the gearbox(M)/torque converter(A).
The driveshaft rolls on a series of bearings along the length of the tube.

In 5 speed models the gearchange configuration is the reverse of the
conventional               R  2  4

The engine does not have "liners" in the cylinder bores which are made of a
light alloy material that has a high content of tiny silicon particles. 
The block is made from a single casting and the bores are machined so that 
the particles of hard silicon protrude from the softer parent material this
provides a certain amount of natural lubrication. In fact the pistons and 
rings only come into contact with pure silicon particles and do not touch 
the aluminium alloy.  

The rear suspension of the 928 is a somewhat flexible arrangement known as
a WEISSACH AXLE. This allows small changes of the rear wheel alignment
depending on driving conditions (acceleration/deceleration/cornering).
These changes in wheel alignment serve to counteract the "natural" 
changes forced on the suspension by driving and so provides more consistant
and sometimes forgiving handling carachteristics.

The Chassis of the 928 is made of steel with much of the outer panels
being made from aluminium and plastic.
