Williams FW33 ? Lowline gearbox (Scarbsf1's Blog)
"One fear from the outsiders point of view would be the structural efficiency of such a waisted design, especially the vertical spar, that supports the wishbones leg above the differential. Williams would either have to compromise weight or stiffness to make the design efficient. So despite the loss of a large proportion of the gear case, the gain may be offset by the penalty of added weight to make the remaining structure stiff enough."Williams FW33 Interim Livery pictures
