How Fast Is A Gtr R35

Alright, let's talk about speed – specifically, how fast a Nissan GT-R R35 really is. We're not just talking about manufacturer claims, but diving into the engineering and factors that contribute to its blistering performance. If you're a GT-R owner, a prospective buyer, or simply a gearhead interested in what makes this car tick, understanding its capabilities is crucial. This knowledge is invaluable not just for bragging rights, but also for informed modifications, track day preparation, and even basic troubleshooting. This isn't just about top speed; it's about acceleration, handling, and the technology that brings it all together.

Key Specs and Main Parts Contributing to Speed

The GT-R R35's performance is the result of a carefully engineered symphony of components working in harmony. Let's break down the key players:

Engine: VR38DETT

At the heart of the beast lies the VR38DETT, a 3.8-liter twin-turbocharged V6 engine. DETT stands for "Dual Engine Twin Turbo." This engine is hand-assembled by a single technician, known as a Takumi, ensuring precision and quality. Over its production run, the VR38DETT has seen numerous revisions, boosting power output from the initial ~480 hp to well over 600 hp in later models like the Nismo. Important specifications include:

  • Displacement: 3799 cc (3.8 liters)
  • Configuration: V6, 60-degree angle
  • Turbochargers: Two IHI turbochargers, each dedicated to one bank of cylinders
  • Fuel System: Multi-point fuel injection
  • Compression Ratio: Varies slightly by model year, but typically around 9.0:1

Transmission: GR6 Dual-Clutch Transmission

The GR6 is a 6-speed dual-clutch transmission. Dual-clutch transmissions (DCTs) offer incredibly fast and seamless gear changes because one clutch engages the next gear while the other is still engaged with the current gear. This near-instantaneous shifting contributes significantly to the GT-R's rapid acceleration. Key features of the GR6 include:

  • Dual Clutch System: Enables lightning-fast shifts.
  • Paddle Shifters: Provide manual control over gear selection.
  • All-Wheel Drive (AWD) Control: The transmission is integrated with the GT-R's advanced AWD system.

All-Wheel Drive System: ATTESA E-TS

The ATTESA E-TS (Advanced Total Traction Engineering System for All-Terrain) is Nissan's sophisticated all-wheel-drive system. Unlike traditional AWD systems, the ATTESA E-TS is a rear-biased system that can send up to 50% of the engine's torque to the front wheels when needed. This provides excellent grip and control, especially during acceleration and cornering. The system uses sensors to monitor wheel speed, steering angle, and throttle position to determine the optimal torque split.

Aerodynamics

The GT-R's exterior design isn't just for looks; it's meticulously engineered to minimize drag and maximize downforce. The low drag coefficient helps achieve high top speeds, while the downforce generated by the rear wing and underbody diffusers improves stability and cornering grip at high speeds.

How It Works: The Synergy of Speed

The GT-R's speed isn't just about raw horsepower. It's about how these components work together. The VR38DETT provides the power, the GR6 transmission delivers it efficiently, and the ATTESA E-TS system ensures that power is effectively distributed to the wheels. The advanced aerodynamics keep the car planted and stable at high speeds. Here's a simplified breakdown:

  1. Power Generation: The VR38DETT produces substantial horsepower and torque through forced induction (turbocharging).
  2. Power Transmission: The GR6 DCT translates the engine's power into rapid acceleration with minimal power loss due to its lightning-fast shifts.
  3. Traction Management: The ATTESA E-TS system intelligently distributes torque between the front and rear axles to optimize traction based on driving conditions.
  4. Aerodynamic Efficiency: The car's aerodynamic design minimizes drag and maximizes downforce, improving stability and grip at high speeds.

Real-World Use – Basic Troubleshooting

Understanding these systems helps with basic troubleshooting. For example, if you experience:

  • Hesitation during acceleration: Could indicate issues with the turbochargers, fuel system, or transmission. Check for boost leaks, fuel injector issues, or transmission codes.
  • Poor handling in wet conditions: Could be related to the ATTESA E-TS system. Check the AWD system's sensors and actuators.
  • Overheating: Check coolant levels, radiator condition, and fan operation. A faulty water pump or thermostat could also be to blame.

Remember, these are just starting points. Complex issues may require professional diagnosis.

Safety – Risky Components

Working on a GT-R requires caution, especially when dealing with these components:

  • Turbochargers: Can get extremely hot. Allow them to cool completely before working near them.
  • High-Pressure Fuel System: Depressurize the fuel system before disconnecting any fuel lines to prevent fuel spray.
  • Transmission: Complex and requires specialized tools and knowledge for repairs. Improper handling can cause serious damage.
  • Electrical System: The GT-R has a sophisticated electrical system. Always disconnect the battery before working on electrical components.

Always consult the service manual and follow proper safety procedures when working on your GT-R.
