The Evolution of the GTR Engine
To fully appreciate what engine does a GTR have, it’s important to look back at the model’s history and how its engineering has developed over the years. The Nissan GT-R’s journey began in the late 1960s, with a legacy intertwined with high-performance motorsport.
Early Beginnings and the Skyline GT-R
The first GT-R engine was introduced with the Nissan Skyline GT-R in 1969. This model was powered by the S20 engine, a 2.0-liter inline-six derived from the Prince R8 engine used in racing. This early model showcased Nissan’s interest in combining sports car performance with usable technology for the road.
RB26DETT and Its Impact
Moving into the early 1990s, the GT-R evolved significantly with the introduction of the R32 Skyline GT-R, which became legendary for its performance. At the core of the R32 was the RB26DETT engine—a 2.6-liter inline-six engine equipped with twin turbos. The RB26DETT gained fame for its robust design and was revered for its tuning potential, allowing modifications that could push power figures into the realm of supercars.
The GT-R R35 and the VR38DETT
The iconic journey of the Nissan GT-R continued with the introduction of the R35 model in 2007. This generation marked a significant leap in technology and performance. The R35 GT-R is powered by the VR38DETT engine—a 3.8-liter V6 twin-turbocharged powerplant. This engine produces immense power and torque, making it one of the most formidable engines in the performance car segment.
Specifications of the GT-R’s VR38DETT Engine
To understand fully what engine does a GTR have in terms of its specifications, let’s take a closer look at the VR38DETT engine that powers the R35 GT-R. This engine is notable for its advanced engineering and impressive performance.
Engine Configuration and Dimensions
The VR38DETT is a V6 engine, which provides a compact form while still delivering the power needed for high-level performance. Here are some key specifications:
- Displacement: 3.8 liters (3799 cc)
- Bore x Stroke: 96 mm x 81.4 mm
- Compression Ratio: 9.0:1
- Valvetrain: DOHC with 24 valves
The engine’s configuration allows for high power output while maintaining a manageable size and weight, contributing to the vehicle’s overall performance and handling.
Turbocharging and Forced Induction
A defining feature of the VR38DETT is its twin-turbocharging system. Each cylinder bank is equipped with its own turbocharger, enabling efficient air intake and promoting quick throttle response. This forced induction capability allows the engine to produce significant power at lower RPMs, making it suitable for both street and track performance.
Power Output and Torque
The VR38DETT engine delivers an impressive output. Depending on the model year and tuning, the power output can vary, but typical figures are around:
- Power: Approximately 480 to 600 horsepower (depending on specific model and setup)
- Torque: Around 430 lb-ft
These figures place the GT-R among the top contenders in the high-performance segment, further enhancing its reputation.
Performance Features of the GT-R Engine
Now that we have examined what engine does a GTR have from a specifications standpoint, let’s explore the various performance features that make the GT-R’s powertrain extraordinary.
Engine Management and Technology
Nissan employs advanced engine management technology to maximize the performance of the VR38DETT. The GT-R features sophisticated software that manages fuel delivery, ignition timing, and boost levels. This electronic management system not only optimizes performance but also enhances fuel efficiency.
Cooling System
The high-performance nature of the GT-R’s engine means it generates substantial heat during operation. To combat this, Nissan incorporates an efficient cooling system that includes dual intercoolers for the turbochargers. This system cools the intake air before it enters the combustion chamber, improving performance and preventing knock.
Exhaust System
The GT-R’s exhaust system is engineered to reduce back pressure while maintaining a throaty sound. Nissan utilizes an active exhaust system that enhances performance by optimizing flow, which is especially beneficial during acceleration.
Transmission Pairing
The VR38DETT engine is paired with a 6-speed dual-clutch transmission (DCT). This transmission allows for rapid gear changes and enhances the overall driving experience. The DCT works seamlessly with the engine, ensuring that power is delivered effectively to the wheels.
The GT-R’s All-Wheel Drive System
One of the standout features of the GT-R is its advanced all-wheel-drive (AWD) system, known as ATTESA E-TS. This system is tightly integrated with the engine, enhancing performance and handling capabilities.
Overview of the ATTESA E-TS System
The ATTESA E-TS (Advanced Total Traction Engineering System for All-Terrain) system allows for the distribution of power between the front and rear wheels. This distribution improves traction during acceleration and cornering, enabling the GT-R to maintain speed and control under aggressive driving conditions.
Torque Split and Handling
The torque split in the GT-R can adjust dynamically based on driving conditions. Under normal circumstances, the GT-R operates with a 50:50 split between the front and rear wheels. However, during high-performance driving, up to 100% of the torque can be sent to the rear wheels, ensuring maximum performance when needed.
Performance on Different Terrains
The GT-R’s powerful engine, paired with its sophisticated AWD system, allows for exceptional performance on various terrains. It performs impressively on wet or slippery surfaces and provides a sense of confidence for the driver in adverse conditions.
