Lubrication System; Cooling System; Transmission - Maserati GranTurismo Coupe Owner's Manual

Lubrication system

The engine lubrication system is of the
dry sump type with scavenge and
delivery pumps aligned with the
cooling pump, in a single unit driven
by the crankshaft through a chain.

Cooling system

The engine is cooled by means of an
anti-freeze mixture with circulates
inside a specific line system equipped
with a radiator, a centrifugal pump
and an expansion tank.

Transmission

Clutch
Dry double-plate clutch with servo-
assisted hydraulic control.
Manual gearbox and "Cambiocorsa" gearbox
Six forward speeds and one reverse.

"Cambiocorsa" gearbox
The electronic gearbox technology,
which was originally designed for
Formula 1 racing, has become today a
standard production component.
The "Cambiocorsa" is a "hydraulic
servo" system for the gearbox and the
clutch, which however features all the
advantages of the dry clutch and
mechanical gearbox (reduced weights,
strength and reliability, low
consumption levels). At the same time,
it is more user-friendly, reduces strain
from driving in the city traffic or when
a frequent gearshifting is required.

Furthermore, it provides excellent
performance, soft gearshifting and
progressive torque on the wheels.
Thanks to the hydraulic servo and to
the interface with the engine
controller (ECU) as well as with the
drive control devices (ASR/MSR), the
system is capable of performing
"sport" or "comfort" gearshifting,
depending on the driver's needs and
driving style.
The clutch pedal is not fitted in the
passenger compartment; the gearshift
lever is replaced by electric controls
(Up-Down) on the steering wheel, just
like on Formula 1 autos.
