The
wind tunnel model of the B05/40 differs in the details to the final product.
It would appear that the pontoon fenders have a slight taper outboard on the model. On the actual car the fenders are slab sided.
The
rear deck appears much lower on the wind tunnel model. The rear wing
endplates are very different and do not mount to the bodywork as here.
The
valance plate covering the radiator inlets is implemented differently than
on the actual car. Here on the wind tunnel model it is directly attached
to the sidepd/rad inlet and is at the same height. Where as on the
actual car it is mounted to the pontoon fender (its leading edge is inline
with the cockpit and the plate terminates just after the leading edge of
the radiator inlet) and sits just above the sidepod masking it slightly.
