Proven in motorsport, and serially installed on the PanameraTurbo S E-Hybrid Sport Turismo, the Porsche Ceramic Composite Brake (PCCB) is available as an option. The cross-drilled ceramic brake discs of PCCB have a diameter of 420 mm at the front and 410 mm at the rear – for even more formidable braking performance. PCCB features 10-piston monobloc aluminium fixed brake calipers on the front axle and four-piston units at the rear – all painted in yellow – to provide braking forces that are considerably more powerful and, crucially, are exceptionally consistent. PCCB enables shorter braking distances in even the toughest road and race conditions. Safety under high-speed braking is also improved thanks to its excellent fade resistance. Another advantage of PCCB is the extremely low weight of the ceramic brake discs, which are approximately 50% lighter than standard discs of a similar design and size. This results in better roadholding and increased comfort, particularly on uneven roads, as well as greater agility and a further improvement in handling.
