Pictured above is the Sauber installation but the Swiss outfit is supplied by Ferrari and therefore uses the same hybrid power unit (ICE + ERS), gearbox, gear case and manifold.
The latter has been revamped and is now shorter and more compact compared to last year’s exhaust pipe. The gear case, which also fits the turbine, has been redesigned as well: its flared lower part is now enclosed and thus more rigid.
The gear case includes many elements: the turbine, part of the manifold, the collector and part of the single exhaust
Ferrari’s gearbox case includes many elements: the turbine, part of the manifold, the collector and part of the single exhaust. In order to protect these and other key components – the clutch, the shafts, the torsion bars, etc. – from the heat, the inside of the case has been covered with insulating material.
The entire assembly is now stiffer with a lower centre of gravity and features less twisted pipework, which in turn increases the power released by the ICE. The new design also improves internal airflow circulation, while the tighter rear end leads to better aerodynamics in a vital area of the car.
