(from Maserati Press
Release) International debut at the 2012 Edition of the
Paris International Motor Show for Maserati: the GranCabrio MC.
Designed to complete Maseratiís open-top range, the new Maserati
GranCabrio MC blends high performance and sports characteristics
derived from racing experience with the style, charm and
practicality of Maseratiís four seater convertible.
This debut is framed by Maseratiís presentation of the complete,
revamped Sport range, including the GranTurismo Sport, the
GranCabrio Sport Ė recently presented at the Moscow Motor Show Ė and
the Quattroporte Sport GT S.
Inspired and encouraged
by the considerable success of the GranTurismo MC Stradale, which
was warmly received by customers thanks to a masterly translation
and adaptation of racing characteristics for use on the road, the
new GranCabrio MC completes the open-top range with a highly sporty
and aggressive look, while maintaining the strengths and
characteristics of a true grand tourer, ideal for long journeys.
The new, sporty look can
be seen in each stylistic element of the GranCabrio MCís bodywork.
Inspired directly by the cars of the Maserati Trofeo MC World Series
and the GT4 version, the new design perfectly blends sportiness,
dynamism, the search for aerodynamic perfection, elegance and style.
These stylistic elements already partly characterised the
GranTurismo MC Stradale and the GranTurismo Sport, and seamlessly
unite form and function.
The car, 48 millimetres longer than the GranCabrio and GranCabrio
Sport, is characterised by a front end which is inspired directly by
the MC Stradale, adopting a profile designed to optimise the
aerodynamic lift and flow. These differ from those on other versions
of the GranCabrio due to the increased car length and other
aerodynamic elements at the rear end.
Thanks to experience
gained in racing and above all to specific analysis of fluid
dynamics, the new GranCabrio MC has an aerodynamic lift coefficient
(measured at 140 km/h) which is 10% lower at the front and 25% lower
at the rear compared to the GranCabrio and GranCabrio Sport.
The bonnet incorporates
two generous air outlets at the centre to optimise cooling of the
powerful V8, and two more air outlets to cool down the brake discs
have also been added to the two front wings.
Initially introduced on the GranTurismo Sport the new headlights,
which adopt LEDs for the daytime running light (DRL) function,
complete the new look of the GranCabrio MC. Though they maintain the
external shape seen on the other three versions in the GranCabrio
range, the new headlights adopt the most modern technology,
perfectly enhanced with an extremely sporty look thanks to the matt
black colour of the structure.
The bi-xenon unit inside
the headlight also incorporates Adaptive Light Control, which
follows the movement of the steering by up to 15 degrees.
The rear is
characterised by the large spoiler, for greater negative lift at
high speeds. Inside the spoiler, built into the luggage compartment,
is the third brake light. The standard version comes in the same
colour as the body and it is also available, within the various car
customisation packages, with a carbon finish.
The bumper has been
completely redesigned at the bottom to make the new model even
sportier and at the same time ensure optimal aerodynamic efficiency.
The circular exhausts have been moved to the centre of the bumper
and the specific layout of the air ducts, built into the lower part
of the bumper, ensure greater streamlining, stabilising the air flow
from the underbody.
Finally, the dynamism of
the GranCabrio MC is accentuated by the 20" MC Design rims,
available in glossy Titanio or matt Grafite, and made using
flow-forming technology. In addition to being lighter, they feature
the traditional Trident, skilfully worked into the double-spokes.
The interior of the
GranCabrio MC has received a thorough overhaul with particular
attention paid to ergonomics.
The new seats,
completely redesigned from both an aesthetic and functional point of
view and enhanced with high-quality materials, now ensure the
optimum balance of comfort and performance, elegance and
functionality. The new structure of both the front and rear seats
now incorporates the headrest and is enhanced by an upper, central
trim, with a design inspired by the carís front grille.
Particularly important, especially with convertible cars, is the
attention paid to the rear passengers. For this reason, the frame
for the front seats, which is also available in a completely carbon-fibre
version, has been completely redesigned to ensure 20 mm more legroom
for the rear passengers.
Particular attention has been paid to the ergonomic and
comfort-related aspects of driving. The seats, with an increased
profile to enhance their wrap-around structure and lateral
containment, ensure sporty driving while guaranteeing superior
comfort, even on very long journeys.
The steering wheel
features a new design, with the rim flattened at the top and bottom
for greater manoeuvrability, also for sports and high-speed use,
without interfering with the driverís legs.
The rear seats have been
redesigned according to the same logic: maximum comfort, maximum
passenger restraint in sports driving and ample use of quality
To complete the new,
super-sporty look of the new GranCabrio MC, it incorporates the
Trofeo-design steering wheel paddles as standard, with increased
dimensions as seen on the GranTurismo Sport, and an aluminium pedal
Engine and performance
As with the most sporty
GranTurismo in the range (the GranTurismo Sport), the GranCabrio MC
also adopts the new 4.7-litre V8 engine, which delivers 338 kW (460
HP) together with substantial torque of 520 Nm at 4,750 rpm.
The pistons, positioned
at an angle of 90į, are made of reinforced, hardened aluminium, as
is the engine block. The crankshaft, with five-point balancing, is
made of high-strength steel.
The timing system, with a system of two chains per bank, features
dual variable valve timing.
The new power unit, in combination with the MC Auto Shift
transmission, is now able to propel the GranCabrio MC, in closed
soft top configuration, to a top speed of 289 km/h with acceleration
of 0 to 100 km/h in 4.9 seconds.
Automatic transmission (MC Auto
Like other sports models
in the Maserati range, the GranCabrio MC also adopts an automatic
six-speed ZF transmission able to transfer all the power of the 460
HP V8 engine to the ground. Calibrated specifically for application
on the sportiest version in the GranCabrio range, the MC Auto Shift
transmission features five operating modes. It can be used in
Auto-Normal, Auto-Sport, Manual-Normal, Manual-Sport and Ice modes.
In Manual mode, gear
changes are carried out directly by the driver through the steering
wheel paddles, as with a truly manual gearbox. In Manual-Normal
mode, the driver can change gear until the threshold value is
reached, while in Manual-Sport mode the gear is maintained until the
driver next changes gear, even if this may result in over-revving
and the intervention of the limiter.
On the GranCabrio Sport,
Sport mode includes super-fast mode, which derives directly from the
GranTurismo Sport and the Quattroporte Sport GT S and permits gear
changes that are 50% faster.
This mode includes automatic blipping (short burst of acceleration)
when downshifting with the Launch Control system, called MC Start
Strategy (which operates only with MSP deactivated).
Using the MC Start Strategy, the driver holds down the brake pedal,
presses the accelerator pedal and then releases the brake pedal when
the optimum engine speed is reached (2,300Ė2,500 rpm).
Chassis and suspension
Performance, safety and
comfort were the guidelines that Maserati engineers followed when
designing the chassis for the new GranCabrio MC. In light of the
experience gained with the GranTurismo MC Stradale, it is fitted
with single-rate dampers, to give maximum emphasis to the carís
sporty character, which guarantee greater rigidity in order to
ensure optimum road holding in all driving conditions, without
detracting from maximum passenger comfort.
Braking, always powerful
and safe, is guaranteed by Maseratiís patented Dual Cast system,
which includes brake discs with aluminium bell and steel braking
surface, 360◊32 mm at the front and 330◊28 mm at the back.
This system guarantees
the best pedal feeling and braking efficiency, which translates to
an excellent stopping distance of 100 to 0 km/h over just 35 metres.
In addition to the
conventional holes to optimise cooling of the discs, they also
feature grooves which allow the film of water, which deposits on the
discs when driving on wet surfaces, to be eliminated and ensure that
the operation of the padís friction material is restored in order to
ensure maximum power and braking efficiency at all times.
The one-piece aluminium
alloy brake calipers, produced by Brembo and available in various
colours, are also six-piston at the front and four-piston at the
rear. This configuration ensures greater uniformity in braking, a
constant clamping force and the sensation of a stable and reliable
pedal, reducing brake wear at the same time.
In deference to Maserati
tradition, the monocoque chassis is made with different materials to
ensure maximum weight reduction and maximum torsional rigidity. The
use of high-strength steels for the structural part and the use of
aluminium and composite materials for the moving parts, ensure
maximum performance in complete conformity with the spirit in which
the new GranCabrio MC was conceived.
