Heating, Ventillationand Air Conditionning(HVAC)

The air conditioning/heating system of the GranTurismoprovides enhanced air flow obtained with new and suitably dimensioned air lines. The system has been designed to assure comfort in all possible weather conditions.

Coolant

The coolant used is R134a. PAG RL -897

This vehicle system is filled with: 600 ±20 g of fluid

Lubricant

The fluid used is Oil UconRL897

This vehicle system is filled with: 200 ml ±10 ml of fluid.

Compressor

The compressor (1) allows the system to vary the flow rate of the coolant reaching the evaporator gradually. It draws the motion directly from the crankshaft by means of the poly-V belt (2).

• Front distribution unit: this is the housing inside which the external air, or recirculatingair, is conditioned and distributed to the vents selected by the user. The distribution unit houses air flaps

• Evaporator: this is a heat exchanger housed in the air distribution unit. It is designed to draw heat and humidity from the air blown into the passenger compartment, by exploiting the coolant transformation from the liquid to the gaseous state.

• Radiator heater: this is a heat exchanger connected to the cooling circuit of the engine by means of two lines: one draws the hot water from the engine, the other allows the coolant to return to the engine. The heater is designed to provide the heat required to heat up the air blown into the passenger compartment.

• Air flap actuators

• Air temperature sensors

• Pollen filter: this is a combined air filter for the passenger compartment : particles and active carbons. It is designed to filter the air coming intothe passenger compartment. The first layer (particles) prevents pollens and pollutant particles from entering the passenger compartment; the second layer (active carbons) reduces bad odours due to humidity that forms on the surface)

• The electric fan is controlled by a 12 V brushless electric motor and is operated at different speeds by a signal from the NCL (A.C. system node). Itis located inside the air conditioning/heating unit near the evaporator)

• Anti-mist sensor: the anti-mist sensor is an electronic device which is designed to send a control signal to the recirculation flap: When the windscreen mist index exceeds the preset thresholds, the flap is forced open to allow intake of outside air regardless of the recirculation mode set by the user. When the windscreen mist index returns to the preset acceptable values, the recirculationflap resumes the mode active before this operation. It is fitted on the internal rear-view mirror.

• Sunlight sensor: the sunlight sensor measures the thermal energy generated by the sun. It is positioned on the dashboard near the windscreen. It is a DUAL ZONE sensor, which ensures optimal control over the air conditioning and heating system temperatures.

• Outside air temperature sensor: this sensor (1) is designed to read the outside air temperature. It is an NTC sensor fitted inside the external rearview mirror, on the driver's side. It has an operating range of -40°C / 80°C.

HVAC node (NCL)

The HVAC node (NCL) (1), located on the right-hand side at the front passenger's feet, is fitted on the air conditioning/heating unit. It is connected to the low-speed B-CAN network. The air HVAC node (NCL) receives the following information from the Body Computer node (NBC), through the CAN network:

•outside air temperature

•engine water temperature

•engine RPM

•vehicle speed (tachometric signal)

•battery voltage (battery charge level)

•heated rear window activation

•compressor status

•status of the vehicle lights.

9. Body

The chassis of the Maserati GranTurismoderives from the Quattroporte, but has a smaller wheelbase and rear overhang (wheelbase: -125mm; rear overhang: -66 mm). It is composed of high-resistance boxed steel sheets and incorporates a tubular structure in position with the rear section, which supports the suspension and the differential, and a front section which supports the suspension and the engine. Due to the reduced wheelbase, the torsionalrigidity of the GranTurismochassis has been significantly improved with respect to the Quattroporte.

Different materials and technologies have been used in the construction of the new loadbearing body for optimal weight distribution. The structural component is made of steel, the lid and the front reinforcement cross member of the bumper is made of aluminium, and thermo-hardening plastic was used for the luggage compartment (a technology known as Sheet MoldingCompound -SMC)

The luggage compartment is made out of one single piece that incorporates the aerodynamic lip. As well as offering greater resistance to lightimpacts and corrosion, the SMC technology has allowed reducing the weight of the components and has given the designer the possibility to best express his creative spirit. The high rigidity values allow the suspension to operate with extreme precision, to the advantage of dynamic handling, at the same time reducing vibrations and undesired movements of the internal components. All this amounts to greater driving comfort on any road surface.
