Introduction

Introduction

The fastest, lightest and most powerful car in the Maserati range inspired by theMaserati Corse experience in the Maserati Trofeo and FIA GT4 championship.Maserati, on the basis of the well performing GranTurismo S and thanks to theexperience on the racetrack with the Trofeo and GT4 version, is debuting with theGranTurismo MC Stradale. This model makes large use of the Maserati Corseexperience, as clearly stressed by the name.Therefore it represents the real link with the racing environment and shows Maserati'sability to develop a product both for road and racetrack use.

This document was drawn up to provide the Maserati technicians with essentialinformation that will allow them to diagnose and perform the necessary service andrepair operations on the vehicle. It provides an overview of all the technical aspects ofthe vehicle and describes in greater detail the systems that distinguish it from theGranTurismo S.

Vehicle overview

Concept

Responding to Maserati customer demands for a GranTurismo capable of balancingtheir road-driving needs with their race-driving desires, the GranTurismo MC Stradaleincorporates the handling and aerodynamic lessons from all three of Maserati’s currentracing programs.

Inspired by the race-winning GT1 (with the MC12), the GT4 and the GranTurismo MCTrofeo motorsport programs, the Maserati GranTurismo MC Stradale features:

With 331kW, its 4.7-litre V8 engine provides more power (450 hp instead of 440) vs theGranTurismo S, while its 510Nm torque result in a further 20Nm improvement. Thiscontributes to slash the 0-100km/h sprint time, which the Maserati GranTurismo MCStradale covers in just 4.6 seconds, and stretches the top speed to 301 km/h.

Vehicle overview

• More power,• Reduced weight,• Reduced gearshift time• Razor-sharp handling• Top speed of over 300 km/h

Maserati Academy 5


Exterior

The GranTurismo MC Stradale’s race-bred heritage is highlighted by a 110kg weightreduction vs. the GranTurismo S, down to 1770kg. It mirrors the advantages thatMaserati has in racing by retaining the optimal 48 : 52 weight distribution to ensurehandling balance and even tyre wear.It uses advanced electronics to slash gear-shift times from the upgraded MC RaceShift electro-actuated Transaxle gearbox to just 60 milliseconds.

The GranTurismo MC Stradale is also the first Maserati in history to have a dedicatedRace driving mode to add to its upgraded Automatic and Sport modes in a simplifieddash layout. It produces more aerodynamic downforce without producing moreaerodynamic drag, it produces more power without using more fuel and it is more agilewithout sacrificing the GranTurismo S’s highly praised ride quality.

Maserati Academy 6


The design of the rear area, the lightweight new race-style seats, a sportyleather/Alcantara combination for the upholstery, a redesigned instrument cluster and anew HMI button layout are the interior highlights of the GranTurismo MC Stradale.

To reinforce just how at home the GranTurismo MC Stradale will feel for race-styledriving, the pedals are now drilled aluminium as standard.While the rear seats have been removed, the style has not. The rear underdoor istrimmed in luxurious carpet, with the Maserati Trident stitched onto an Alcantara pad inthe centre of the rear bulkhead.

Lighter than leather, Alcantara is largely used to trim the centre console, the armrest lid,the door armrests and handles and the curve above the instrument cluster.

Front sport seats

Interiors

Vehicle overview

The seats of the GranTurismo MC Stradalehave been designed focusing on the highperformance of the vehicle: they provideexcellent support in all driving conditions andmaintain the classic combination of a sportsand luxury car in one.

Maserati Academy 7


The seats combine a carbon-fibre shell with high-tech padding and materials and evenhave the Trident logo stitched into the headrests in the same colour of the interiorstitching. They offer manual adjustment to move the base backwards and forwards andto move the backrest angle.They also offer three different height options, adjustable on demand.

With its sportier philosophy, the luxury hints of chrome and alloy have been removedfrom the GranTurismo MC Stradale in favour of a black look to reflect race-car interiors.This extends, even, to the instrument cluster, where the traditional Maserati bluebackground colour has given way to black, with an entirely new typeface for thespeedo and tacho dials.

MC Sport Line options

The MC Sport Line carbon fibre parts are also available to customise the interior andthe exterior of the GranTurismo MC Stradale together with the carbon fibre interiorfinishes, a carbon fibre gearshift paddle kit and other components in the same material.

Options: Roll bar upon request with four-point racing harness

To reflect its more-heightened focus, the GranTurismo MC Stradale also has the optionof a roll cage, which bolts in to the car.This optional part is also available with a four-point racing seatbelt harness,homologated for road use, fastened on the rear cross member of the roll cage. The rollcage is protected with three Alcantara coverings in the same colour as the INTG areas.The standard 3-point seat belt is in alternative to the RACY option. The 4-pointharnesses are completed with the seat belt reminder function on both seats. Refined 4-point seat belts covers in black alcantara with Maserati logo (stitched always in silvercolour) are included in the RACY pack. Selecting the RACY option it is also possible tochoose the colour of 4-point seat belts (ModisCS code: BELTS: red, black, blue).

The GranTurismo MC Stradale can also be stressed by the specific, custom-developedlivery, with a Maserati Trident skewed at 45 degrees on the roof and the MC Stradalelogo on both sides of the car.The red and grey streaks of the MC signature underline the achievements of theaerodynamics engineers: the colour enters the brake inlet ducts and exits the vent inthe front quarter panel before blending into the door.

The GranTurismo MC Stradale in the Maserati model range

The push for the GranTurismo MC Stradale came from existing GranTurismo andGranTurismo S customers who wanted a car that looked and felt like the GT4 andTrofeo race cars, but was road legal and just as comfortable as their existing models.With the removal of the rear seats, the GranTurismo MC Stradale will be the only two-seat Maserati in the current line-up. It has been designed to give a deeply engaging,racing-car driving experience, regardless of what kind of road its drivers are on.To achieve that and still maintain Maserati’s traditional values, it had to look, sound andfeel like a racing car without sacrificing its road comfort.

1. Engine

The GranTurismo MC Stradale’s engine is a spin-off of the F136 YE and delivers331kW at 7000 RPM, which is a 10 horsepower improvement vs. the GranTurismo S.There is also more torque, with a 20Nm jump from the GranTurismo’s strong 490Nm to510Nm at 4750rpm, with a thicker torque curve at lower RPM.Most of the improvements are the result of the “Low Friction Program”, which involveda new design of the oil sump fluid dynamics and DLC (Diamond-Like Coating) of thehydraulic tappets and the camshaft lobes. The engine has thus gained in power andconsumption efficiency and consequently produces lower emissions.

Engine features:• 90°, 8 V-cylinders entirely made of aluminium with a capacity of 4.7 litres and a wet

sump lubrication system. High-efficiency combustion chambers.• Variable valve timing system (VVT) on the intake camshafts. The timing variators

have an angular stroke of 50°.• Motronic ME7.1.1 engine control system.• The MC Stradale is equipped with an exhaust bypass system. The bypass valves

flap are permanently open in Race mode and open from 4000 rpm in Sport mode.

The redesigned and lighter tailpipes of the exhaust system create a richer, moreintense and louder sound.For the GranTurismo MC Stradale to come closer to the spirit of a racing car, thevalves on the exhaust tailpipes have been maintained, which bypass the silencer anddetermine a stronger racing-like identity. In Race mode the valves are permanentlyopen. In Sport mode, the valves open according to the engine RPM/accelerator pedalmap starting from 2500 RPM and staying completely open over 4000 RPM.The exhaust tailpipes have also been positioned higher up and towards the centre ofthe vehicle, like for the GT4 and Trofeo competition models.

To best exploit the performance of the new 450 HP V8 4.7 engine, the GranTurismoMC Stradale is equipped with an robotized gearbox, like the recent Maserati modelswith a more racing-like setup. This technology is part of the Maserati DNA and springsfrom the close ties the Trident has with the world of competition. Moreover, comparedto the earlier versions, the system has been implemented with the RACE gearshiftfunction coupled to the new “Superfast shift 2” (CV2 – Cambio Veloce 2) controlsystem that further reduces the gearshift time during high-performance driving.

From a technical point of view, the robotized gearbox is an electrically-hydraulicallycontrolled, mechanical transmission with a dry double-plate clutch and 6-speedgearbox (plus reverse) with triple-cone synchronizers on the 1st and 2nd gear, anddouble-cone on the others. The hydraulic servo control is controlled by thetransmission ECU (NCR) through the paddles integral with the steering columnaccording to a pattern whose ergonomics and effectiveness in driving at the limit haswidely been tested.The 6-speed gearbox comes in combination with a double-plate clutch, a solutionderiving from the world of competitions and particularly suitable for more racing-stylevehicles. The reduced dimensions of the clutch assembly (215 mm Ø) and the small-diameter flywheel (240 mm Ø) significantly contain the weight of the assembly withevident reduction of the total engine inertia compared to a single-plate system. Thistype of setting allows more easily reaching the maximum engine RPM, faster gearboxresponse, faster gearshifting and, last but not least, better driving dynamics.

The robotized gearbox is controlled through the gearshift paddles on the steeringcolumn and through the buttons on the centre console for 1st gear and reverse gearengagement and for activation of AUTO, SPORT and RACE modes.

Selecting one of these three modes, the gearbox softwarestrategy implements an adjustment of the gear engaged,shifting one or two gears down depending on the modeselected.

This should give the driver the feeling that the vehicleresponds quickly and promptly to his precise request for highperformance driving.

Transmission

Maserati Academy 27


Auto Mode

The gearbox strategy requires that the vehicle always be started in automatic mode. Inthis operating mode, the gearshifts are completely automatic based on a gearshift mapprogrammed in the Robotized Gearbox Node (NCR). The gearshift strategy has beendefined to get the best compromise between driving comfort, contained consumptionsand vehicle performance.In this mode, the gear engaged is shown on the display together with the indication“AUTO”.Note: When driving in automatic mode, gearshifting can still be manually controlledusing the paddles on the steering wheel. When the driver uses the manual controls, thegearbox temporarily goes back to Manual mode; during this interval, the indication“AUTO” on the display flashes for about 5 seconds, after which the system goes backto Automatic mode.

“Auto easy-exit mode” strategy

Every time the engine is started, the gearbox system is set to AUTO mode. If theengine is turned off with either SPORT or RACE mode set, the next time the engine isstarted, the “Auto easy-exit mode” strategy activates AUTO mode.This condition is indicated by the word “AUTO” flashing on the display. This strategyallows the driver to go back to SPORT mode simply by first shifting gears manually(using the UP and DOWN paddles).If the driver does not shift gears after two minutes of driving, the system automaticallyactivates AUTO mode.

RACE mode

Gearshifting in RACE mode is the most recent innovation of the robotized gearboxsystem. This mode exploits the elastic energy of the transmission devices and resultsin very fast gearshift times and absolutely outstanding performance. The result is agearshift time which drops to 60 ms (measured as acceleration dip), a value thatensures the best sports handling and unrivalled driving emotions.

SPORT mode

In SPORT mode, the gearbox control system follows a gearshift control strategy morefocused on performance, with much shorter changing times between one gear and thenext in relation to RPM and the accelerator pedal position.In SPORT mode, the exhaust pneumatic valves are open. In addition to giving theengine a fuller and deeper sound, the lower counter pressure allows the engine toincrease its RPM more rapidly and enhance its maximum power. Downshifting isaccompanied by a more accentuated double-clutch effect.Upon exceeding 4000 RPM and with the accelerator pedal 80% depressed, the fuelcut-off strategy is activated (engine turned off and fuel supply cut off) duringgearshifting: this reduces the torque discharge time and the drop in engine RPM,resulting in faster gearshifting.

Transmission

Maserati Academy 29


Superfast gearshift is available in MANUAL RACE mode only.

When the vehicle F1 kit oil and engine coolant have reached the operatingtemperature and RACE mode has been selected, the letters MC-R illuminate on thedisplay. This means that the following conditions have occurred:

• Engine speed > 5000 RPM

• Accelerator pedal depressed >65%

• Lateral acceleration <0.9g

• ASR not in operation

• No wheel slipping

RACE gearshift in 60ms. When?

Activation of this strategy is communicated to the driver via the “MC-R” icon, which at first flashes on the display and then

remains permanently illuminated.

In RACE mode, the GranTurismo MC Stradale can change gear in just 60 milliseconds(0.06 seconds) thanks to a precise control and gear selection optimisation. The MC-Race gearshift is available only if specific conditions are met: a temperature suitable forall the vehicle systems has been reached and the accelerator pedal is at least 65%depressed. When these conditions occur, MC-Race fast gearshift is activated, which isindicated on the display with the red “MC-R” warning light.

Transmission

Maserati Academy 30


Sequential downshifting of more gears can be obtained by setting one of the twomanual modes, SPORT or RACE, and holding the DOWN lever pulled and the brakepedal depressed. The number of downshifts and the downshift speed depend on thebraking duration and intensity.

Sequential downshifting strategy

Transmission

Redesigned hydraulic actuator to reduce shifting timesIn order to further reduce the needed time for a gearshift operation it was necessary todevelop a system that does not require a centering in the neutral position during thegearshifting.

This system involves removing the engagement actuator tappets and increasing thelever/fork clearance, consequently increasing the actuator stroke by 2mm.Simplification of the system, thanks to the elimination of the centering tappets andrelative seals, use of a piston shaft with only one seal, reduced machining work on theengagement shaft due to the elimination of the sealing seats.

The interface components have been redefined:

• Gearshift finger

• Latch and relative drive bushings

All the self-learning procedures of the GranTurismo S model remain unchanged,including “Fast gearshift”. This procedure should be performed after gear self-learningcycle and subsequently at KEY OFF /KEY ON.

This self-learning procedure is required to self-learn the solenoid valve disengagementtimes.

It must be performed each time a gearshift structure needs to be self-learned.

This must be performed after self-learning of the gearshift structure and after removingthe key.

The procedure is performed using the Maserati diagnostic tester with KEY ON in thesame way as for gearshift structure self-learning.

You will hear 13 strokes (selection) followed by 3 engagements of 1st, 2nd, 3rd, 4thand 5th gear in sequence. 6th gear and Reverse will not be engaged.

The Maserati MC Stradale is the first Maserati equipped with a braking system withcarbonceramic discs (CCM) on the four wheels as standard. This has variousadvantages compared to the conventional system. The greater braking efficiencyallows reducing the stopping distance from 100 km/to 0 km/h from 35 to 33 metres.

• Tandem brake master cylinder, vacuum brake servo (booster), separate hydraulicbrake circuit with cross layout.

• Front axle: Single-piece aluminium brake calipers with 6 pistons of differentdiameter. Ventilated and perforated brake discs obtained with CCM technology,diameter x thickness 380 x 34 mm. The single-piece brake calipers are moreresistant to deformation than compound brake calipers, which means that lightermaterials can be used, thus reducing the component weight. In addition, the brakecalipers are more efficient at any operating pressure and the brake pedal stroke ishence shorter.

• Rear axle: Single-piece aluminium brake calipers with 4 pistons of differentdiameter. Ventilated and perforated discs, diameter x thickness 360 x 32 mm.

• Electronically-controlled "Drum in Hat" parking brake (EPB) with "auto-apply","drive-away" and "pre-release" functions.

GranTurismo MC Stradale Braking system

Finally, the CCM system provides a weight reduction of approx. 50% vs. cast irondiscs, because of the lower density of the ceramic material, and improves the vehicleoverall performance, achieving friction coefficients of approx. 0.36 vs. 0.28 of cast ironsystems. Being unsprung weights, they enhance the vehicle dynamics and improvedriving comfort.

Compared to conventional systems, response times are improved and performancelevels are maintained in the event of heavy-duty use. Among the most evident effects isthe elimination of the fading effect, which affects the control feeling perceived on thepedal travel and load. In addition, the carboceramic discs have a practically unlimitedlife in normal conditions of use, with evident advantages in terms of costs.In general, the new braking systems must be run in and that is why they only reach anoptimal braking action after two or three hundred kilometres. The slightly reducedbraking action must be set off by increased pressure on the brake pedal.

Carbonceramic discs have a carbon fibre structure which is properly directed andsubjected to heavy stress inside the production mould, so that the discs produced areequipped with channels for heat dispersion. Subsequently, they undergo acarbonisation process in a kiln at approximately 1000°C in the presence of nitrogenand then to further processes, such as radial drilling of the braking surface.Compared to the discs used in Formula One vehicles, the road vehicle discs are furtherprocessed by dipping them in a silicon bath, which makes them efficient also at lowtemperatures.The application of this new braking system has contributed to improving all the brakingperformance parameters (enhanced deceleration/pedal load ratio, braking distances,fading resistance) and to considerably reducing unsprung weights.

Maserati Academy 36


The CCM braking surface and the drive housing form one singleassembly that must not be separated, disassembled or modified(machining, etc.), under any circumstance. The discs areavailable from the Maserati Spare Parts Department completewith their own housing.

MOVEMENT

CCM is a composite ceramic material and is therefore extremely hard but, at the sametime, "fragile”. As a result of this, greater caution is required and special care must betaken during handling and/or fitting operations in the vehicle.During transportation and internal handling, the disc must be protected with a specialpolyethylene foam packing, which must be disposed of appropriately.The following faults may be caused by incorrect handling :

CAUTION

Each disc is identified with a progressive number etched onto the housing. Thisnumber allows tracing back to the process and product parameters.

• wrong use of instruments and tools and/or improper fitting procedures

Maserati Academy 37


• Be extremely careful with the edges (knocking against the outside diameter andinternal crown).

• Do not use levers or screwdrivers to move the caliper pistons backwards whenreplacing the pads.

• Do not hammer on the braking surface to remove the disc of the hub (if necessary arubber hammer)

• Avoid causing compression stress to the braking surface (by closing it in a vice orany other kind of equipment).

• Do not use levers or screwdrivers in the ventilation channels to move or rotate thedisc.

• When handling and/or fitting the disc (without its protective packing), werecommend you use the centre hub as a gripping point.

Maserati Academy 38


Disc inspection

Visually inspect the braking surfaces whenever the vehicle is brought to the workshop,so that major surface variations can be identified.The wear condition of the brake discs must be checked each time thebrake pads arereplaced.The wear condition of the discs is assessed by means of the following checks:

DISC TO BE REPLACED DISC TO BE REPLACED

Braking system

• Inspection after intensive use on the race track

• Visual inspection of the porosity/roughness of the disc surface

• Checking the disc weight loss

• Checking the damage on the edges of the brake disc edges (damage caused bymisuse)

Maserati Academy 39


The CCM discs are to be replaced when one of the following conditions occur:

The CCM discs are subject to wear only in extreme conditions of use (on the racetrack) or when the discs reach temperatures higher than a certain temperature range(>500°C). In these conditions, oxidation occurs in the carbon fibres in the CCM.

CHECKING THE DISC WEIGHT LOSS

If subjected to extreme thermal stress, e.g. use on the race track, the disc brakingsurface may be heavily oxidised, to such an extent that the disc weight may bereduced.If the vehicle is used in these conditions, the discs need to be weighed in order toensure that the braking system is always in such conditions as to guaranteeperformance in perfect safety.

2. Accidental disc damage (impact, dropping, etc.)

3. Braking surface damage because the brake pad is worn out.

4. Reaching the comfort acceptability limit (noise, feeling on the brake pedal)

5. Excessive drop in performance

Maserati Academy 40


In order to reduce the measurement error to a minimum, the weight loss indicationsmust be double-checked by visually inspecting the discs and taking the followingprecautions before weighing it:•Thoroughly clean the disc before making the measurement (clean out the ventilationholes and clean the housing)•Check the wear condition of the surface•Check for humidity (if found, dry the discs in an oven at 200°C for about 1h)Chipped discs, but not so badly that they need to be replaced, will not affect the discweight (low density).The CCM brake disc must be replaced when its weight is equal or lower to the MIN.weight shown on the brake disc housing.

In contrast to cast-iron discs, the thickness of the CCM disc braking surface is notindicative of the wear condition.

MAINTENANCEFor proper functioning and to obtain the maximum CCM brake disc efficiency, thebraking surface must be clean and free of any stains or grease and/or oil buildups.This type of soiling may reduce the friction coefficient.The deposits can be removed by cleaning the surface with solvents, such as acetone(C3 H6 O) or alcohol.Do not use any kind of brake cleaner (trichloroethane).If the pads have any stains or signs of oil and grease, use the same degreasers asused for the discs and/or lightly sand the surface with sandpaper.

ESC

The Maserati MC Stradale is equipped with ESC (Electronic Stability Control) anti-yawing system, which incorporates all control systems: ABS, EBD, ASR and MSR).This system controls all the dynamic functions of the vehicle in relation to braking,stability in a bend, and traction control. The different dynamics are controlled byvarious specific functions all integrated in the NFR (Bosch ESP 8.0):

• ABS (anti-lock braking system for the wheels during braking): it prevents the wheelsfrom locking during braking

• ASR (Anti-slip Regulation): prevents the wheels from slipping during acceleration.• EBD (Electronic Brake-force Distribution): guarantees ideal distribution of the brake

force between the front axle and the rear axle based on the vehicle weight and thedynamic conditions.

• MSR (Motor Schleppmoment Regelung): performs the electronic control function ofthe engine braking torque in downshift condition to guarantee vehicle stability.

• MSP (ESP), (Maserati Stability Program): performs the individual control functionof the brake of each wheel to guarantee vehicle stability in a bend.

• HHC (Hill Holder Control): helps the driver during uphill starting preventing thevehicle from rolling back in the time between brake pedal release and acceleratorpedal depression.

• HBA (Hydraulic Brake Assist): assistance during emergency braking.

Hydraulic brake assist (HBA)• Helps the driver in the event of emergency braking• Function integrated in the Bosch ESP 8.0 ECU (NFR)• It is based on information received from the hydraulic pressure sensor to measure

how fast the driver depresses the brake pedal. When emergency braking, the brakepedal is in fact often depressed fast but not with sufficient force.

• If an emergency braking condition is detected, the system increases the brakepressure by means of the hydraulic pump.

• This function reduces the stopping distance in the event of emergency braking, thusincreasing the safety level.

Developed in conjunction with Maserati’s test engineers and based on the experiencefrom the Trofeo championship, the new PZero Corsa tyres have been designed tomove the handling-comfort balance of the GranTurismo S’s tyres further towards purehandling.

While the GranTurismo S already had good track performance, the new tyres havebeen developed to maximize grip in a very short time and, in concert with a moreprecise "feedback" feeling for the driver, to maintain that grip for as many laps aspossible, thanks to rubber compounds derived from Pirelli’s racing experience.The rear tyres have an asymmetric pattern with large tread blocks on the outsideshoulder for high lateral grip.

The GranTurismo MC Stradale rides on a new, custom-developed tyre from the Italiantyre maker Pirelli – the same company that developed and supplies the tyres for theTrofeo GranTurismo MC.Designed to be at home both on the road and on the race track, the 20-inch PirelliPZero Corsa tyres are slightly wider than the standard tyres on the GranTurismo S andoffer even more grip.

The GranTurismo MC Stradale is equipped with a double airbag for the driver and thefront passenger. These airbags exploit a technology first used on the Quattroporte andsubsequently also on the GranTurismo. It is an "intelligent" system that independentlyadjusts to the occupant’s height and controls airbag opening in the event of a collision.The new passenger-side airbag with its "Low Risk Deployment" function is acomponent at the top of range for occupant protection and guarantees an excellentlevel of safety in head-collisions.As well as improving passive safety, this new solution is also a major improvement inthe styling of the upper panel of the passenger-side dashboard, now more linearthanks to the integrated airbag.

The already high effectiveness of the bixenon headlights has further been enhancedwith the orientation function that improves illumination of the track and the surroundingareas with the resulting increase in the safety levels while driving at night or on windingroutes.The low-beam ECU reads the instantaneous information on steering and the steeringangle as well as the driving speed and acts on special electric motors to turn the lightcones.Main characteristics:

• The system is activated when the speed exceeds 5 km/h.• The maximum headlight rotation towards the inside of the bend is 15° and towards

the outside 7.5° (always half).• From 90 km/h to 120 km/h the swivel angle is reduced;• Over 120 km/h and in reverse, the system is not activated for safety reasons.


Parking sensors:The vehicle is equipped standard only with rear parking sensors integrated in the rearbumper. Front parking sensors not available.The icon of the car surrounded by symbols showing the distance from the obstacles(max/med/min) is displayed on the instrument panel. The symbols illuminate in threedifferent colours based on the distance of the obstacles from the vehicle: max-green,med-yellow, min-red. An acoustic warning is sounded when the symbols light up.

Cruise control:When driving at a constant speed, Cruise Control is particularly useful, as it allowssetting the cruising speed that will automatically be maintained without having to act onthe accelerator pedal.When the driver activates Cruise Control, the system automatically sets a specialgearshift strategy taking the gradient of the road into account and performs thenecessary calibration to guarantee maximum comfort and avoid unnecessarygearshifts.

Maserati Multi Media System

The infotainment system onboard the Maserati GranTurismo MC Stradale derives fromthe new IT platform developed by Magneti Marelli.A 7" high-resolution TFT colour display situated in the centre of the dashboard allowsthe user to view the CD player, the GPS navigation system (if the cartography isavailable), the radio and the onboard computer (travel information and vehiclesettings). System performance has further been improved by using a 30GB automotivehard disk on which the entire cartography can be uploaded and which also offers ajukebox function instead of the CD player. On the one hand, the hard disk driveconsiderably reduces the trip calculation times and, on the other hand, allows storingup to 180 hours of music that can be copied directly from Audio CDs or downloaded toMP3 files through the USB port situated in the passenger-side glove compartment.The system also allows using your own MP3 reader; in effect, most of the readerscurrently available on the market can be connected via the USB port so that you canlisten to your favourite music while travelling.The GPS navigation system with its large colour display and 3D graphic processorallows navigating with a very fetching perspective view.The system is easy and intuitive to use thanks to the controls in the centre of thedashboard, and the most frequently used functions are accessible in full safety bymeans of the buttons on the multifunction steering wheel. Again from the safety point ofview, the audio system, the navigation system and the telephone (if present) can beactivated by means of a voice control system.The “Text to Speech" synthesizing system (artificial reproduction of the human voice)further contributes to the driver’s safety as he or she can listen to SMS messages andTMC traffic information without being distracted by looking at the display.The Multi Media System is equipped with Bluetooth technology, for mobile phoneconnection. This allows the user to make and receive calls through the speakers andmanage the contact list through the Multi Media System.

Bose Surround Sound system

The system is available on request. To play powerful and clear music, the Bose Surround Sound System has two separate bass sources. The double low-frequency sources are designed to work with the complete system and faithfully reproduce music in a wide frequency spectrum.Conventional approaches to multiple bass sources may prove to be problematic. If thespeaker is situated too close to the listener, the sound may be deafening; if it is too faraway, the sound may be too weak. Improper positioning may cause some frequenciesto distort, virtually killing the sound instead of boosting it.Thanks to the close cooperation with the Maserati development team, the Boseengineers took an audio project specifically developed for the Maserati MC Stradale asan example, selecting the most suitable speakers and the most appropriate position forbest performance. The system includes a custom-made speaker with twoNd®Richbass® woofers positioned between the rear seats, and one Nd®Richbass®woofer in a customised bass reflex speaker at the front, powered by a single amplifierwith two-stage modulation.The Nd®Richbass® woofer combines the lighter weight and the power of a neodymiumiron boron magnet with a design that allows reproducing the low frequencies of a muchbigger and heavier speaker. It is housed in a custom-made box concealed behind thepassenger-side footwell. These specific speakers and their positioning are keyelements that have allowed more uniform transmission of low-frequency sound,guaranteeing improved musical impact without reducing the available space in thevehicle. AudioPilot® noise compensation circuits:The Bose Surround Sound system includes AudioPilot® noise compensation circuitsdesigned with an algorithm specifically dedicated to the acoustic profile of the MaseratiMC Stradale. The system helps maintain the high quality of the listening experienceonboard, compensating the effects of the noise generated by speed as well as externalacoustic phenomena not related to the vehicle speed. The AudioPilot® system rapidlyprovides a wide compensation range and is able to best distinguish a continuous noisefrom a brief and transitory one caused by bumps in the road and other sudden changesin the road surface. This compensation is automatic so that the sound level perceivedand the tone balance remain constant. Thanks to this solution, the driver canconcentrate on the road and enjoy the absorbing experience of listening to good musicand feeling the sensation the artist wants to transmit.


Maserati Academy 54


The Bose Surround Sound System in the Maserati vehicles is controlled by a Bosedigital amplifier, which includes Centerpoint® and SurroundStage® signal processingcircuits and eight channels for equalization as required. The Bose system allows theoccupants to disable the Surround Sound and AudioPilot functions directly from theMMS in order to optimise listening in disturbed conditions.

The system is equipped with twelve high-performance speakers and the followingelectronic system components:


1) One 80 mm Nd (Neodymium) Twiddler for high and medium frequencies, positionedcentrally on the dashboard.2) Two 36 mm Nd (Neodymium) Tweeters positioned in the passenger compartment, inposition with theexternal rear-view mirrors.3) Two 165 mm Nd (Neodymium) speakers for low and medium frequencies on each ofthe door panels.4) One 13 cm Nd®Richbass® woofer (Neodymium) powered by an amplifier withtwo-stage modulation fitted in the passenger-side footrest.5) Two 165 mm Nd (Neodymium) speakers for low and medium frequencies, on theside panels of the rear seats.6) Two 80 mm Nd (Neodymium) Twiddlers for high and medium frequencies, positionedon the sides of the rear parcel shelf.7) One 255 mm Nd Power® woofer powered by an amplifier, positioned centrally onthe rear parcel shelf.

iPod dock

On request, the Maserati MC Stradale can also be equipped with an iPod interface.This allows the occupants to listen to music by connecting an iPod to the dock situatedin the glove compartment using an adapter cable and to use the main iPod functionsdirectly through the multimedia system (MMS). The iPod functions in the iPod Modemenu are shown on the display in the centre of the dashboard.


A.C. systemThe dual-zone air-conditioning system maintains the ideal temperature conditions inthe vehicle by automatically adjusting the interior temperature and ventilation intensityin relation to the outside temperature, sunlight intensity and air humidity.The fully electronic dashboard allows the driver and the passenger to separately setthe temperature from a minimum of 16°C to a maximum of 32°C, while the air flowdistribution through the two vents in the centre console ensures an ideal temperaturein the rear area as well.The system is also equipped with a demisting sensor: if the window temperaturedrops to below the dew point causing the window to mist up, the sensor automaticallyactivates to reduce the percentage humidity in the air.
