The Porsche 911 RSR (991) from 2017 measures 4557 mm (179.4 inches) in length, making it a fairly long sports coupe. Its width is 2042 mm (80.3 inches), reflecting its wide and aggressive stance optimized for racing performance. The height is not specified here but the car is known for its low profile, aiding aerodynamic efficiency and stability on the track. These dimensions contribute to the vehicle's dynamic handling and high-speed capabilities.
The 2017 Porsche 911 RSR (991) has a curb weight of 1243 kg (2740 lbs). This relatively lightweight construction is crucial for a race-oriented vehicle, allowing for improved acceleration, agile handling, and better braking performance. The low weight is achieved through extensive use of lightweight materials and engineering focused on reducing mass without compromising the structural integrity essential for racing.
The 2017 Porsche 911 RSR is equipped with wide rims specifically sized at 12.5J x 18 inches at the front and 13J x 18 inches at the rear. Correspondingly, the tire sizes are 30/68 R18 at the front and 31/71 R18 at the rear. These large and wide wheels and tires provide the necessary grip and stability required for high-performance racing, enhancing traction and cornering capabilities on various track surfaces.
The Porsche 911 RSR (991), with a length of 4557 mm (179.4 inches) and width of 2042 mm (80.3 inches), may be challenging to fit into smaller or older standard garages, which usually accommodate cars up to around 2 meters (78.7 inches) in width. Its width is slightly above average due to its race-spec design. However, most modern garages with a standard width of at least 2.4 meters (approximately 8 feet) should be able to accommodate it comfortably. The low height also helps ensure vertical clearance is not an issue.
Compared to its predecessor, the 911 RSR (997), the 991 generation has a slightly longer and wider body. The 991 measures 4557 mm (179.4 inches) in length and 2042 mm (80.3 inches) in width, while the 997 was shorter and narrower overall. This increase in dimensions improved aerodynamic efficiency and enhanced stability at high speeds. Additionally, the newer model benefits from a lower overall weight and advanced materials, making it more competitive on the racing circuit.
When compared to similar GT race cars, such as the Ferrari 488 GTE or the BMW M8 GTE, the Porsche 911 RSR (991) sits competitively in terms of size and weight. Its length of 4557 mm (179.4 inches) and width of 2042 mm (80.3 inches) put it in the mid to large size category for GT race cars. The curb weight of 1243 kg (2740 lbs) is relatively lightweight, which helps in agility and acceleration. Each competitor balances dimensions differently to optimize aerodynamics, handling, and engine performance depending on racing regulations and design philosophy.
The Porsche 911 RSR (991)'s wheel sizes of 12.5J x 18 inches in the front and 13J x 18 inches in the rear, coupled with the wide tires (30/68 R18 front, 31/71 R18 rear), are designed to maximize grip and durability under racing conditions. The large contact patch provided by these tires improves traction during cornering and braking, essential for endurance and sprint racing formats. The staggered setup (slightly wider rear tires) helps manage power delivery to the track, contributing to better balance and handling.
The Porsche 911 RSR (991) is a racing coupe specifically developed for GT (Grand Touring) endurance racing. Produced between 2017 and 2019, it was designed to compete in top-tier GT categories like the FIA World Endurance Championship and IMSA WeatherTech SportsCar Championship. It emphasizes lightweight construction, aerodynamic efficiency, and race-tuned performance rather than everyday driving comfort or convenience.
The dimensions of the Porsche 911 RSR (991) are optimized primarily for track performance. Its wide stance (2042 mm / 80.3 inches) and large tires enhance grip and stability during aggressive cornering and high-speed runs, while the relatively long length (4557 mm / 179.4 inches) supports aerodynamic elements and balance. Unlike street cars, comfort and practicality such as parking ease or garage fitment are secondary considerations to maximizing lap times and reliability under racing conditions.
At 1243 kg (2740 lbs), the Porsche 911 RSR (991) is significantly lighter than many road-legal sports cars, which often weigh between 1400 to 1600 kg (3086 to 3527 lbs). This reduction in weight is achieved through race-specific materials such as carbon fiber and lightweight alloys, as well as stripped-down interiors focused on performance. This makes the car exceptionally agile and quick on the track but less practical for daily driving.
