2017 IMSA RXR One Super Gran Turismo Dimensions, Size & Specs

The RXR One Super Gran Turismo’s width is influenced by its very broad tire sizes, with front tires measuring 305/30 ZR20 and rear tires wider at 315/30 ZR21. These correspond to rims sized 12.0J × 20 inches at the front and 12.5J × 21 inches at the rear, making the car exceptionally wide for a sports coupe. This wide track and tire setup enhance the vehicle’s cornering stability and grip, enabling superior traction and handling at high speeds. The wide tires allow for increased contact with the road surface, which is critical for the car’s supergran turismo capabilities, ensuring impressive control whether on racetracks or spirited road drives.

Weighing in at 1296 kg (about 2857 lbs), the IMSA RXR One Super Gran Turismo is designed with a focus on lightweight construction to maximize performance. This relatively low curb weight allows for enhanced acceleration, better braking response, and more agile handling compared to heavier vehicles. Lower weight improves fuel efficiency indirectly by requiring less power to move the car, though this is secondary to performance in a supergran turismo vehicle. The weight distribution, combined with wide tires and a low center of gravity, helps deliver a dynamic driving experience characteristic of high-end sports coupes.

Although exact length and height dimensions are not precisely disclosed for the RXR One Super Gran Turismo, the car’s configurations with wide and large-diameter rims (20 inches front, 21 inches rear) and low curb weight suggest it maintains a relatively compact supercar footprint. Generally, standard garage dimensions are around 6 meters (about 19.7 feet) in depth and 3 meters (approx 9.8 feet) in width. Given the RXR One’s sporty coupe proportions and typical supercar packaging, it should fit comfortably within a standard double garage. However, due to wide rims and large tires, the car may take up most of the width, so careful parking might be necessary in narrower single car garages.

The rim sizes of 12.0J × 20 inches at the front and 12.5J × 21 inches at the rear paired with large tires (305/30 ZR20 front, 315/30 ZR21 rear) contribute significantly to the car’s wide stance and aggressive road presence. These wide rims and tires extend the track width, which improves stability during cornering and high-speed driving by maximizing tire contact patches. The staggered setup also enhances traction by allowing a wider rear footprint to effectively transfer power during acceleration, a common trait among high-performance coupes geared toward driving dynamics.

The IMSA RXR One Super Gran Turismo is a relatively new model first produced in 2017, and as such it doesn’t have a direct predecessor to compare against in a traditional sense. This model stands as IMSA’s flagship supergran turismo coupe, showcasing advanced design and engineering concepts without a lineage predecessor. Being an innovative entrant in the supercar segment from IMSA, its dimensions focus on delivering a lightweight, wide, and agile package optimized for performance rather than evolving from a previous platform.

Compared to other supergran turismo vehicles in the market, the IMSA RXR One Super Gran Turismo offers a very competitive weight at 1296 kg (2857 lbs), which is notably lighter than many rivals that often exceed 1400 to 1600 kg. The wide tire setup with 305 mm and 315 mm widths at large diameter rims makes its stance particularly aggressive, rivaling top-tier supercars like the Ferrari 488 or Lamborghini Huracán in terms of grip and road presence. Its compact size, though not fully detailed dimensionally, fits well within the norms of this car segment ensuring it balances nimble handling with the necessary aerodynamic profile of a supergran turismo.

The IMSA RXR One Super Gran Turismo comes equipped with very wide and large-diameter rims and tires to maximize grip and handling. The front setup features 12.0J × 20 inch rims paired with 305/30 ZR20 tires, while the rear setup steps up to 12.5J × 21 inch rims with 315/30 ZR21 tires. This staggered wheel setup not only improves traction and cornering capability but also gives the vehicle an aggressive, high-performance aesthetic fit for a supergran turismo coupe.

The IMSA RXR One Super Gran Turismo is classified as a coupe, specifically designed as a supergran turismo vehicle. This designation implies a high-performance sports car blending grand touring comfort with supercar-level speed, agility, and driving dynamics. Its coupe body style with two doors focuses on lightweight construction and aerodynamics, making it suitable for both road and track use while emphasizing style and driver engagement.

The IMSA RXR One Super Gran Turismo has been in production since 2017 and remains in production to the present day. This ongoing production indicates the vehicle’s sustained appeal and relevance in the niche supergran turismo market. The continuity in production allows IMSA to maintain updates and potentially introduce technical or aesthetic improvements while catering to enthusiasts seeking a unique and exclusive coupe with cutting-edge design and performance values.
