The team were subsequently required to redesign the gearbox and completely overhaul the rear suspension mounting points in order to fit the engine.
The changes required to accommodate the SPE-01 allowed Sauber to develop a radical design to the rear suspension geometry as well as wheelbase elongation.
The design combined all of the upper elements of the suspension into a single piece, thus minimizing the amount of bodywork in a key area of the chassis and in turn reducing drag whilst giving the team a greater degree of control over air flowing over the rear diffuser and producing more aerodynamic grip.
The team introduced a temporary cooling package for the duration of the test ahead of a planned update to the car's bodywork, and later expressed confidence that the engine reliability issues had been resolved.
Herbert's impressive season culminated in the team's third-ever podium finish at the 1997 Hungarian Grand Prix (where he also beat both works Ferraris).
