Nissan GT-R: what drive and why does it make it unique?

When it comes to Nissan GT-R, the first thing that comes to mind is its incredible dynamics, aggressive design and legendary status among sports cars. But behind these characteristics lies complex engineering, the key element of which is all-wheel drive system. Many people wonder: what kind of drive does it have? GT-R and how does it differ from analogues?

The answer is simple: all generations Nissan GT-R (from R32 1989 to modern R35) are equipped permanent all-wheel drive ATTESA E-TS (Advanced Total Traction Engineering System for All-terrain - E-TS). However, behind this name lies a whole philosophy of power management that makes GT-R one of the most technologically advanced and unpredictable cars in the world. Let's figure out how this system works, why it is so important for the characteristics of the machine, and what nuances should be taken into account during operation.

Drivetrain evolution across generations of the Nissan GT-R: from R32 to R35

All-wheel drive system ATTESA debuted on Skyline GT-R R32 in 1989 and has undergone several modifications since then. It was originally developed to improve handling on off-road and wet tracks, but soon became a key element of the car's racing potential. In every new generation GT-R engineers Nissan we refined the torque distribution algorithms to make the car even faster and more predictable.

This is how the system changed ATTESA in different versions:

• 🔧 R32 (1989–1994): First generation with mechanical differential lock and torque distribution 50:50 by default. The system was simple but effective for the time.
• 🔄 R33 (1995–1998): Electronic control appeared ATTESA E-TS, which could dynamically redirect up to 50% of the torque to the front axle.
• ⚡ R34 (1999–2002): Improved algorithms and faster response to clutch changes. It was this version that became iconic thanks to its participation in racing and films.
• 💻 R35 (2007–present): Completely redesigned system with three modes (Comfort, Sport, R-Mode) and the ability to manually adjust torque distribution.

It's interesting that in R35 system ATTESA works in tandem with GR6 transmission (6-speed dual-clutch transmission), which allows power to be distributed between the axles in a fraction of a second. This makes the car incredibly sharp at the start and stable in corners.

How the ATTESA E-TS system works: technical details

System ATTESA E-TS — this is not just “all-wheel drive”, but a complex complex of sensors, electronic units and mechanical components. Its main task is react instantly to loss of traction and redistribute torque between the front and rear axles, as well as between wheels of the same axle (thanks to limited slip differentials).

Here are the key components of the system:

• 📡 Sensors: Wheel speed, steering angle, longitudinal and lateral acceleration, throttle position.
• 🖥️ Electronic control unit (ECU): Analyzes data from sensors and makes decisions about torque distribution.
• ⚙️ Multiplier clutch: A mechanism that physically distributes power between axles. B R35 An oil-cooled electromagnetic clutch is used.
• 🔄 Differentials: Front and rear limited slip differentials (LSD) for better grip in corners.

Normal mode GT-R sends most of the power to the rear axle (up to 100% in some situations), but when slipping the system can redirect up to 50% torque to the front axle. This happens so quickly that the driver does not even have time to notice the loss of traction.

Parameter	R32/R33	R34	R35
Max. front axle moment	30%	40%	50%
System response time	~100 ms	~50 ms	~10 ms
Coupling type	Mechanical	Electro-hydraulic	Electromagnetic
Operating modes	1 (auto)	2 (auto/sport)	3 (Comfort/Sport/R-Mode)

One of the most interesting aspects ATTESA in R35 - this is the ability to manually adjust torque distribution through the system VDC (Vehicle Dynamic Control). For example, in mode R-Mode the car becomes more rear-wheel drive, which is what experienced drivers like for drifting.

Why does all-wheel drive make the GT-R so fast?

Main advantage ATTESA E-TS - this is maximum use of available power no losses due to slipping. While rear-wheel drive cars may lose traction when starting hard, GT-R distributes torque so that all four wheels accelerate.

Here are some examples of how this manifests itself in practice:

• 🚀 Standing start: Thanks to all-wheel drive GT-R R35 accelerates to 100 km/h in 2.7 seconds (modified Nismo). By comparison, many rear-wheel drive supercars clock times of 3.0+ seconds.
• 🏁 Exiting corners: The system allows you to “accelerate” earlier at the exit, since the front axle helps to “pull” the car.
• 🌧️ Wet track: ATTESA minimizes the risk of skidding, which makes GT-R one of the safest sports cars in the rain.

However, there is a downside: all-wheel drive adds weight (clutch, additional shafts, differentials), which slightly worsens the dynamics compared to purely rear-wheel drive cars of the same class. But the engineers Nissan were able to balance this disadvantage due to a powerful engine VR38DETT (3.8 l, 570–720 hp depending on version).

The myth about the "eternal" all-wheel drive GT-R

Many people believe that the ATTESA system does not require maintenance, but this is not true. The clutch and differentials have a limited life, especially during aggressive driving. For example, in the R35 it is recommended to change the clutch oil every 60,000 km, and for track use - 2 times more often.

Comparison with competitors: GT-R vs. Porsche 911 vs. Audi R8

To understand the uniqueness ATTESA, it's worth comparing GT-R with other sports cars that also use all-wheel drive, but in different ways.

Model	Drive type	Torque distribution	Features
Nissan GT-R R35	ATTESA E-TS	0:100 to 50:50	Electromagnetic clutch, 3 modes, rear axle orientation
Porsche 911 Turbo	PTM (Porsche Traction Management)	5:95 to 50:50	Fluid coupling, smoother distribution
Audi R8 V10	Quattro	40:60 (default)	Mechanical Torsen differential, permanent all-wheel drive

Main difference GT-R from competitors is aggressive torque distribution in favor of the rear axle. While Audi R8 strives for a balance of 40:60, and Porsche 911 Turbo can send up to 95% of the moment back, GT-R in mode R-Mode It behaves almost like a rear-wheel drive car, but with support for the front axle. This makes it more lively and predictable for experienced drivers.

However, this approach also has disadvantages: at the limit GT-R may suddenly go into a skid if the system VDC disabled. Therefore, for beginners it is recommended to use the mode Comfort, where electronics intervene more actively in control.

Common GT-R drive problems and how to avoid them

Despite the reliability, the system ATTESA not eternal. Here are the most common problems owners face GT-R:

• ⚠️ Clutch overheating: During intense driving (such as on the track), the clutch may overheat, resulting in loss of torque distribution efficiency. The symptom is jerking when accelerating.
• ⚠️ Differential wear: Front and rear LSD require regular oil changes (every 30–50 thousand km). Skipping maintenance results in humming and vibration.
• ⚠️ Electronic failures: System sensors may fail, resulting in activation Check Engine or refusal VDC.
• ⚠️ Oil leak from clutch: B R35 This is a common problem, especially after 100 thousand km. Requires disassembly and replacement of seals.

To extend the life of the system ATTESA, follow these guidelines:

Particular attention should be paid oil in the clutch. B R35 special liquid is used Nissan Matic S ATF, which cannot be replaced with analogues. It is also important to monitor the condition VDC - if the system turns off by itself, this may be a sign of a malfunction of the sensors or control unit.

⚠️ Attention: If your GT-R started to “steer” when accelerating or jerking appeared, check the clutch immediately ATTESA. Further use may lead to its complete failure, and repairs will cost several thousand dollars.

Modifications and tuning of the all-wheel drive system

Many owners GT-R strive to improve vehicle performance, and the system ATTESA - is no exception. Here are the most popular modifications:

• 🔧 Clutch update: Replacing the standard coupling with a reinforced one (for example, from Nismo or Dodson) allows you to withstand heavy loads when tuning the engine.
• 💻 ECU firmware: Some tuning studios offer to reflash the control unit ATTESA, to change the logic of torque distribution (for example, make it more “rear-wheel drive”).
• 🛠️ Reinforced differentials: Replacement of standard LSD for sports (for example, Cusco or OS Giken) improves grip in corners.
• 📉 Disabling VDC: Some racers turn off the stability control completely, but this requires high driving skill.

However, it is worth remembering that any modifications ATTESA may affect reliability and controllability. For example, too “aggressive” firmware can make the car unpredictable on a wet track. Therefore, before tuning, it is recommended to consult with specialists who have experience working specifically with GT-R.

One of the most popular tuning packages is Nismo Club Sport, which includes a heavy-duty clutch, sports differentials and a re-flashed ECU. This upgrade allows you to squeeze out GT-R maximum on the track without sacrificing reliability.

GT-R off-road: myth or reality?

Many are surprised to learn that Nissan GT-R capable of driving off-road. After all, the system ATTESA E-TS was originally developed as "all-terrain" (as the name suggests - All-terrain). Of course it's not Patrol or Navara, but thanks to all-wheel drive and high ground clearance (compared to other sports cars) GT-R Can overcome light off-road conditions.

Here are some examples where GT-R may surprise you:

• 🌊 Mud and puddles: Thanks to torque distribution, the car does not get stuck in soft ground (unless, of course, it is too deep).
• ❄️ Snow: In mode Comfort with enabled VDC GT-R behaves very predictably in the snow.
• 🏔️ gravel roads: At low speed, the system copes well with slippage.

However, do not delude yourself: The GT-R is not intended for serious off-road use. It doesn't have differential locks, the crankcase protection is weak, and the suspension is tuned for asphalt. But as a “universal” car for the city and light off-road, it will cope better than many supercars.

Interesting fact: in Japan, some owners GT-R R32/R33 use them for winter driving, since the system ATTESA The first generation is very reliable and works well in the snow.

⚠️ Attention: If you decide to test GT-R off-road, be sure to check the ground clearance (only 110 mm in R35) and engine protection. Even a small stone can damage the oil pan.

FAQ: Frequently asked questions about the Nissan GT-R drivetrain

Is it possible to disable all-wheel drive on the GT-R?

No, the system ATTESA E-TS does not have a complete shutdown function. However, in mode R-Mode you can bring the car's behavior as close as possible to rear-wheel drive by turning off VDC and changing the torque distribution settings.

Which drive is better for drifting: GT-R or rear-wheel drive car?

For classic drifting, a rear-wheel drive car (for example, Nissan Silvia or Toyota 86) fits better because it is more predictable. However GT-R in mode R-Mode with disabled VDC also capable of spectacular drifts, but requires more skill due to the connected front axle.

How much does it cost to repair an ATTESA system?

The cost depends on the problem:

• Changing the oil in the clutch: ~$200–$300.
• Clutch repair (clutch replacement): ~$1,500–$3,000.
• Replacement differentials: ~$2,000–$5,000 (depending on model).
• Replacement of sensors or control unit: ~$500–$1,500.

It is recommended to contact specialized services, as the system requires precise tuning.

Can ATTESA be installed on other Nissan vehicles?

Technically this is possible, but extremely difficult and expensive. System ATTESA was developed specifically for GT-R And Skyline, therefore for installation on other models (for example, 350Z or 370Z) will require a complete rework of the transmission, suspension and electronics. Such projects exist (for example, ATTESA on Silvia S15), but their cost may exceed the price of the car itself.

How to check if ATTESA is working properly?

There are several ways:

1. Perform a traction test: when starting hard, all four wheels should rotate equally. If one of the wheels slips more, there may be problems with the clutch or differential.
2. Listen for sounds: a hum or grinding sound when turning may indicate wear. LSD.
3. Check for errors: connect a diagnostic scanner and make sure there are no codes related to ATTESA or VDC.
4. Evaluate the behavior: if the car has become less stable in turns or jerking has appeared, this is a reason for diagnosis.
