2014 Koenigsegg One:1 Dimensions, Size & Specs

The Koenigsegg One:1 has a curb weight of 1360 kilograms, which translates to about 2998 pounds. In the hypercar segment, this is an impressively low weight thanks to the extensive use of carbon fiber and lightweight materials in its construction. The low curb weight dramatically improves acceleration, braking, and cornering capabilities by reducing inertia. It also directly contributes to the claimed power-to-weight ratio of 1:1 — meaning it produces one horsepower for every kilogram it weighs, an extraordinary metric that underlines its exceptional performance and driving dynamics.

The Koenigsegg One:1 offers an extremely low ride height with a ground clearance of just 59 mm (about 2.32 inches). This very low clearance is optimized for aerodynamic performance and handling precision at high speeds. However, it limits the car’s usability on everyday roads with potholes, speed bumps, or uneven surfaces. Drivers need to be cautious of clearing inclines or dips to avoid scraping the underbody. This low clearance is typical for hypercars tuned for track performance rather than everyday comfort or off-road versatility.

The Koenigsegg One:1 is fitted with large rims sized at 9.5J x 19 inches on the front and 12.5J x 20 inches on the rear. These substantial wheel sizes allow fitting wider, performance-focused tires which provide excellent grip and stability during aggressive cornering and high-speed runs. The staggered wheel sizing helps balance front and rear traction demands and ensures optimal handling dynamics. The large rims also aid in heat dissipation from the brakes, which is essential during extended high-performance driving to maintain brake efficiency and safety.

Given its dimensions—4500 mm (177.2 inches) length, 2060 mm (81.1 inches) width with mirrors open, and 1150 mm (45.3 inches) height—the Koenigsegg One:1 generally fits within the bounds of a standard residential garage in terms of length and height. However, its width, especially with mirrors open, can be close to or exceed some narrower garages' clearance widths. Owners are recommended to fold or close the mirrors where possible when parking to avoid contact with walls or other vehicles. Overall, while fitting is possible, careful maneuvering and slightly wider garage spaces are advisable for convenience and safety.

The Koenigsegg One:1 marks a notable evolution compared to earlier models like the Agera. While similar in overall length, the One:1 is engineered to be substantially lighter at 1360 kg (2998 lbs), benefiting from increased use of carbon composites and cutting-edge manufacturing techniques. Its width is also slightly larger, enhancing stability at high speeds. Compared to the Agera, the One:1 has a more aggressive aerodynamic profile, lower height, and a stiffer chassis, all contributing to improved handling and performance. These dimension and weight optimizations set the One:1 apart as a more track-focused hypercar.

In the arena of hypercars, the Koenigsegg One:1 stands out both dimensionally and in performance. Compared to rivals such as the Bugatti Veyron or Ferrari LaFerrari, the One:1 is slightly shorter but wider, with a remarkably lower height, contributing to superior aerodynamic efficiency and a lower center of gravity. Its curb weight of 1360 kg (2998 lbs) is significantly lighter than many competitors, which often weigh well over 1600 kg (3527 lbs). The One:1’s power-to-weight ratio of 1 horsepower per kilogram is exceptional and places it among the fastest accelerating and most agile hypercars globally, demonstrating an edge in lightweight engineering and unmet performance benchmarks.

The Koenigsegg One:1 is designed as a two-seater coupe focused on driver experience and performance rather than spaciousness. Its low height (1150 mm / 45.3 inches) and wide, cockpit-style cabin prioritize ergonomics and driver engagement over passenger comfort. While the cabin is tailored to fit occupants securely for high-speed driving, interior space is tight given the car’s focus on aerodynamics and weight savings. Headroom and legroom are sufficient for typical adult drivers, but the car is not designed for rear seats or extra cargo capacity, reflecting its single-minded hypercar nature.

The Koenigsegg One:1 leverages extensive carbon fiber composites for the chassis and body panels, dramatically reducing weight while maintaining extreme rigidity and crash safety. The use of advanced carbon fiber techniques allows the chassis to maximize structural stiffness and minimize mass simultaneously. Additionally, lightweight magnesium wheels, titanium fasteners, and optimized aluminum components contribute to the low curb weight of 1360 kg (2998 lbs). The car’s design philosophy is deeply rooted in maximizing the power-to-weight ratio, with innovations such as active aerodynamics and carbon ceramic brakes complementing the lightweight architecture to deliver peak performance.

The Koenigsegg One:1’s overall dimensions of 4500 mm length (177.2 inches), 2060 mm width with mirrors open (81.1 inches), and 1150 mm height (45.3 inches) are tailored to optimize aerodynamic efficiency and handling. The relatively compact length allows for sharp agility, while the wide stance provides excellent stability during fast cornering by lowering the lateral load transfer. Its extremely low height reduces frontal area and air resistance, enhancing top speed and downforce capabilities. These dimensional choices are pivotal in achieving the car’s 1:1 power-to-weight ratio performance, making it one of the fastest and most dynamically precise hypercars.
