Premium Midship GT-R:

Premium Midship Package


To ultimate "flat ride sport"


Compatibility of power train cooling and aerodynamic efficiency


Decrease of power train vibration


FR based 4WD generally loads the engine and the transmission on the front. In this case, the length which includes the transmission from the engine becomes considerable ones, in the rigid aspect becomes the disadvantageous material. Vis-a-vis this, separating the engine and the transmission, with the premium midship package which forms independent formation trance axle 4WD, it can decrease the vibration of the power train substantially. Furthermore because the transmission from the driver is categorized to the distance, it decreases also the confined sound near the driver's seat.

Driving position and utility

As for another advantage of this premium midship package, there is a point which can improve the operating environment of the driver. If past by the fact that the transmission which exists near the front seat foot is put on the rear, the foot space of the cabin expands. It became possible to arrange the pedal in ideal position. Because also the cabin guarantees sufficiently, the person of most physiques (height 144cm? Besides the fact that) it can sit down to 190cm, flat also the trunk space actualizes widely with the adoption of the run flat tire. Past there is no super car, height of the utility is held.

The engine VR38DETT :

NISSAN GT-R private new development VR38 twin turbo engine

3.8L V6 twin turbo MAX.POWER 353kw (480PS) /6400rpm - MAX.TORQUE 588N m (60.0kgm) /3200-5200rpm

IHI integrated turbocharger

The left and right bank of V type engine the turbocharger which is installed respectively NISSAN selected IHI make which time-honored racing machine. Utilizing the room of the aerodynamic volume displacement, 3.8L, after guaranteeing low-speed torque, unifying the exhaust manifold and the turbocharger.

Independent intake & exhaust system

The turbocharger, the intercooler and the catalyser - etc. it provides, 2 each adopting the inhalation and exhalation of air system which frees left and right bank each one.

Thermostat attaching oil cooler

The motor oil/oil cooler which cools the turbocharger makes air cooled system, in order always to control temperature optimumly, provides the thermostat. Furthermore, because the lubrication of the motor oil is maintained even in the kind of circumstance where G catches strong revolution with such as circuit travelling.

The Transmission GR6

GR6 dual clutch type transmission







Because basic important matter of the premium midship package which raises the basic efficiency of the vehicle that "it runs, bends, stops" to ultimate is satisfied, the transmission it unifies the 4WD system and mechanical LSD and loads onto the vehicle rear. It arranges the input/output shaft slantedly and by the fact that it converts flat, it has contributed to also center of gravity conversion low. In addition, the directly connected clutch brings, actualizing fast speed change with direct. The result of chasing after the packaging of ideal because the request which is required from NISSAN GT-R as a multiple performance super of 21st century car is actualized, those where it arrives, are the new development GR6 type dual clutch transmission. Linear actualizing running with direct in addition to controlling while it is mind with accelerator operation, with intense acceleration and the powerful engine brake with the control of direct connection of the ボルグワーナー make six plate dual clutch which does not have the slide, driving force. In addition, it corresponds to all travelling conditions the A range (automatic speed change), M range (manual speed change) with change, multiple performance promises the high performance. The speed change response where by the fact that paddle shift is adopted, operation of speed changing can do with M range, easily securely even in operational state of the extremity which receives intense front and back left and right G is fast is actualized. The GR6 type dual clutch transmission is designed to be the structure which respectively has the clutch in the odd level of 1,3,5 and the even number step of 2,4,6. For example, in the odd level the even number step selecting the gear beforehand while travelling, you wait. When the signal of speed change is received, the clutch is changed simultaneously instantaneously. In addition, because it corresponds to the paddle shifting which is continued, you adopted the high capacity triple cone synchronizer for all gears, economized also gear selection time to the extremity. Because of this, while it was throttle full opening boost pressure of the turbo was kept in high state, seamless and strong acceleration became possible to engine highest revolution. Furthermore, when shifting gear the synchronizer points to the engine rpm and the tire revolution, the running which is stabilized by the fact that sudden traction change is held down actualizes with シンクロレブコントロール. If at the time of corner penetration the downshift it does simultaneously with braking, with エンジンブリッピング the needle of the tachometer rises, with the accuracy which exceeds to the heel of the racing driver &, completes speed change instantaneously. In addition, in order to support these efficiencies, as for the GR6 type dual clutch transmission the craftsman/teacher who permits the assembly especially one does one hand composition, precision is guaranteed by the up-to-date inspection equipment.

Dry sump lubrication system
Even under high G condition of the high-speed cornering time and the like with the circuit, stabilizing, in order to be able to do the lubrication, transmission oil adopting the dry sump lubrication system which is injected directly to the gear.

The Aero Dynamics

The compatibility of Cd and down fourth
It tries if probably to decrease aerodynamic drag down fourth becomes sacrifice, if down fourth is preferred, Cd becomes large. So far, Cd and down fourth were in relationship of trade-off. But, in order to actualize the running which NISSAN GT-R aims, these compatibility are indispensable. The result NISSAN GT-R of repeating development Cd which 0.27 you call is a match to the racing machine (aerodynamic drag factor) with, actualized the powerful down fourth which is less than zero lift territories substantially. With this preponderant aerodynamic efficiency, as NISSAN GT-R raises the road-hugging of the tire in all scenes, can show the high performance by the fact that the grip which always is stabilized can be obtained without regrettable, also fuel economy efficiency of the extent which changes the image of the super car is achieved. As for the technology NISSAN to stack so far with development and the like of the FM package of course, the place where it contributes to the independent formation trance axle 4WD which this time is adopted with the premium midship package is large to the actualization of such aerodynamic efficiency. The air style which is introduced from the front grille by moving the transmission to the rear in one, it reached the point where it can let flow into the tunnel smoothly. This as it contributes to power train cooling greatly, is connected to also the decrease of aerodynamic drag. Furthermore, the bottom of the floor is rectified smoothly from the fact that it can designate the floor underside as flat, has made easy to produce down fourth.
