2018 Nissan GT-R50 Prototype Dimensions, Size & Specs

With a width of 1992 mm (78.4 inches), the Nissan GT-R50 Prototype is wider than a typical passenger car, which usually ranges around 1750-1850 mm (68.9-72.8 inches). This increased width contributes to better cornering stability and road grip due to a wider track. However, the added width may make urban driving and parking more challenging, especially in narrow spaces or tight city streets. While practical use is limited by its prototype nature and high-performance focus, potential owners should be aware of the larger footprint when maneuvering in confined environments.

A standard single-car garage typically measures around 2.4 to 2.7 meters (7.9 to 8.9 feet) in width and about 5.5 to 6 meters (18 to 20 feet) in length. The Nissan GT-R50 Prototype, at 1.992 meters (6.54 feet) wide and 4.784 meters (15.7 feet) long, should fit within the length comfortably but will require a wider garage space than average, especially considering the need to open doors and maneuver around the vehicle. Owners with standard garages might find the width slightly limiting, but it remains feasible in most modern or customized garage spaces designed to accommodate larger sports cars.

The low height of 1316 mm (51.8 inches) enhances the aerodynamic profile of the Nissan GT-R50 Prototype, reducing air resistance and improving high-speed stability and fuel efficiency. This low-slung stance lowers the center of gravity, which benefits handling performance during dynamic driving. However, while this height favors performance and aesthetics, it may limit interior headroom and reduce outward visibility. Drivers and passengers may feel more enclosed, and ingress/egress could be less convenient compared to taller vehicles, but these trade-offs align with the car’s focus on sports performance.

The Nissan GT-R50 Prototype comes with large rims sized 10J x 21 inches on the front and 10.5J x 21 inches on the rear. The tire sizes are 255/35 R21 at the front and 285/30 R21 at the rear. These sizable tires and rims allow for a larger contact patch, improving grip and traction, which is critical for a high-performance coupe. The staggered setup, with wider rear tires, optimizes power delivery and stability during acceleration and cornering, enhancing overall handling performance. Additionally, the 21-inch wheels contribute to a more aggressive stance and allow for larger brake components.

As a prototype vehicle, the exact weight of the Nissan GT-R50 Prototype is not commonly disclosed in public sources, but generally, GT-R models have weights ranging from approximately 1700 to 1800 kg (3748 to 3968 pounds). A weight in this range, combined with its powerful engine, contributes to a favorable power-to-weight ratio critical for acceleration and handling. Lighter weight improves agility and braking, while heavier weight can enhance stability. Given the GT-R50's bespoke carbon fiber bodywork and performance focus, it likely maintains a competitive weight balance to optimize dynamic capabilities.

When compared to the Nissan GT-R R35 generation, the GT-R50 Prototype is slightly longer and wider. The R35 measures approximately 4710 mm (185.4 inches) in length and 1895 mm (74.6 inches) in width, while the GT-R50 Prototype boasts 4784 mm (188.3 inches) length and 1992 mm (78.4 inches) width. This increase in size gives the GT-R50 a more pronounced road presence and likely contributes to improved aerodynamics and stability. Height is slightly lower on the GT-R50, enhancing its sleek profile. Overall, these dimensional upgrades signal an evolution toward a more aggressive and performance-oriented design.

The Nissan GT-R50 Prototype shares similarities with other high-performance coupes such as the Audi R8 and Porsche 911 in length and width but distinguishes itself with a unique wide and low stance. The Audi R8 measures roughly 4419 mm (174 inches) long and 1940 mm (76.4 inches) wide, while the Porsche 911 ranges around 4519 mm (177.8 inches) in length and 1852 mm (72.9 inches) in width. The GT-R50's 4784 mm length and 1992 mm width make it larger and more imposing dimensionally. Its prototype status includes bespoke exterior design features, setting it apart visually and technically, appealing to enthusiasts looking for exclusivity and a blend of Nissan heritage with performance car uniqueness.

The Nissan GT-R50 Prototype was developed as a collaboration between Nissan and Italdesign to celebrate the 50th anniversaries of both the GT-R and Italdesign. It features a bespoke carbon fiber body with unique aerodynamic styling cues, including a longer nose and more aggressive lines than standard GT-R models. Powered by a tuned version of the R35 GT-R’s VR38DETT 3.8-liter twin-turbo V6 engine, it produces enhanced horsepower and torque outputs tuned for exclusivity. The suspension and chassis were also refined for improved performance. As a concept, it embodies advanced design and engineering ideas, combining heritage and innovation in a rare limited-run vehicle.

The Nissan GT-R50 was originally unveiled as a prototype concept in 2018 but was later produced in a limited run of 50 units due to high demand. These units were highly exclusive, offered at a significant price premium due to bespoke customization and advanced engineering. While it is technically available for public purchase, the production was limited and primarily aimed at collectors and enthusiasts. Its prototype roots mean that it stands apart from mass-produced GT-R models, with ownership providing a unique combination of exclusivity, performance, and celebrated design collaboration.
