BRAKING SYSTEM, DUAL-CAST DISC TECHNOLOGY
The Maserati GranTurismo S and GranTurismo S Automatic, have a high-performance braking system, based on dual-cast
technology and developed in collaboration with Brembo.
A perfect marriage of the high-temperature performance of cast iron and the light weight of aluminium.
Apart from the power and stability provided by cast iron and aluminium composite, the brakes have 6-piston single-billet
calipers, which ensure that the full braking force is applied to the discs.
The normally red calipers of the Maserati GranTurismo S are also available in 5 customised shades: Titanium and Yellow for
a more striking look, Silver and Dark Blue for a more elegant effect, and classical Black. An anodised red treatment has been
added to these, one developed to harmonise best with the three new opaque bodywork tints.
THE EXHAUST TAILPIPES
The Maserati GranTurismo S gives voice to its 440 Eu Hp through a special exhaust system, designed to emphasise the
burbling sound of the new V8 engine, and unleash performance while ensuring passenger comfort.
Next to the two rear silencers are two pneumatic bypass valves, electronically controlled by the ECU and operated using the
"Sport" button.
In normal conditions, the valves are closed and direct the exhaust gases along a lengthy, twisting path, reducing their energy
and allowing them to leave the system with only a discreet murmur.
When the "Sport" button is pressed, all this changes: the valves open, allowing the gases to flow out of the system more
directly and efficiently, delighting enthusiasts with a thrilling sound and providing a more enthusiastic exhaust sound.
