1939 Cadillac - GM Heritage Center

The hypoid rear axle, transmission extension and
Syncromatic Shift control make it possible to secure
the unusually low floors without resorting to high
transmission and propeller shaft tunnels. In LaSalle
only low crowned surfaces are above the floor level.
Practically all LaSalle interior dimensions have been increased.
Above dimensions taken with front seat in forward position.
Room: In the rear interior a three-inch increase in
legroom has been accomplished by increased tonneau
length and a more deeply recessed footrest. Also the
footrest has been carefully redesigned to give the most
comfortable foot position.
In the front compartment seats are inches wider
at the hips, 1¾ inches wider at the shoulders.
Headroom has been increased 1 % inches in the front
compartment and }/i inch in the rear.
The V-8 engine is the basic reason for improved
efficiency in usable body space. If a straight-eight engine
of equal displacement as the new LaSalle were used, a
wheelbase five or six inches longer would be necessary
to provide LaSalle's roomy dimensions.
