2019 Audi PB18 concept Dimensions, Size & Specs

The Audi PB18 concept has a curb weight of 1550 kg (approx. 3417 lbs). This relatively lightweight for a high-performance concept car is achieved through the use of advanced materials and engineering typical of prototypes aimed at pushing performance boundaries. The weight balance and reduced mass play a significant role in the vehicle's agility, acceleration, and handling characteristics, making it an ideal platform for exploring future high-performance and electric powertrain technologies.

The Audi PB18 concept offers a luggage capacity of 470 liters (approximately 16.6 cubic feet). This is relatively generous for a supercar or prototype coupe, providing reasonable practicality despite its focus on performance. This capacity allows for stowing medium-sized luggage, making the concept less impractical than typical supercars which often sacrifice storage space. However, as a concept vehicle, it is primarily designed to showcase future technologies and design directions rather than everyday utility.

Given its dimensions—4530 mm (178.3 inches) in length and 2000 mm (78.7 inches) in width—the Audi PB18 concept is wider and quite low compared to average vehicles. Most standard residential garages accommodate vehicles up to approximately 5000 mm (196.9 inches) long and between 2100–2200 mm (82.7–86.6 inches) wide including some buffer space. While the PB18 should fit lengthwise, its width is close to the upper limit, meaning tight-fit garages might require careful maneuvering. Its exceptionally low height of 1150 mm (45.3 inches) shouldn't present an issue for garage clearance.

The Audi PB18 concept features large 22-inch rims paired with wide tires sized 275/35 R22 at the front and 315/30 R22 at the rear. The large wheel diameter enhances the car’s aggressive stance and visually fills the wheel arches, which is typical for a performance-oriented concept. The wide tires contribute significantly to grip, improving cornering stability, braking, and overall handling dynamics. These tire specifications are optimized for high-performance driving, matching the concept's sporty design and engineering focus.

The Audi PB18 concept represents a fresh design language and size profile compared to earlier Audi sports prototypes, which typically tended to be smaller or more traditionally shaped. At 4530 mm long and 2000 mm wide, it is relatively large for a two-seater coupe, reflecting modern trends towards wider tracks for performance stability. Unlike many earlier concepts, this model emphasizes a low-slung cockpit and aggressive aerodynamic styling. While direct predecessors differ, the PB18 pushes forward Audi’s vision for future performance cars, particularly emphasizing electrification and driver experience.

When compared to similar high-performance concept coupes like the McLaren Speedtail or the Porsche 918 Spyder, the Audi PB18 concept falls into a comparable size and weight category. Its 4530 mm length and 1550 kg curb weight make it slightly longer but relatively lightweight, showcasing Audi's focus on materials and electric drivetrain technology to keep mass low. The wide 2000 mm stance is also competitive, contributing to excellent cornering abilities. Overall, its dimensions and weight align well with contemporary supercar concepts designed for a blend of speed, agility, and futuristic design.

The Audi PB18 concept’s compact yet wide dimensions help accommodate advanced aerodynamic features such as a low drag coefficient and efficient airflow management. The low height of 1150 mm allows for a sleek profile that minimizes air resistance. Its broad width enhances lateral stability at high speeds, and strategic vents, diffusers, and sculpted body panels manage airflow around and underneath the car. These elements work harmoniously with its size to deliver high downforce, cooling efficiency, and enhanced driving dynamics, underscoring its role as a visionary performance concept.

The Audi PB18 concept is a prototype coupe, designed primarily as a concept car and not as a production vehicle. Its purpose is to showcase Audi’s design direction, cutting-edge technology, including electric and hybrid drivetrain possibilities, and advanced driving dynamics. As a concept, the PB18 is not aimed for mass market use but rather to influence future production models. Its stylized, aggressive stance and performance focus indicate intent toward high-end sports car enthusiasts and technology innovators within the automotive industry.

Being a prototype and concept vehicle, the Audi PB18 concept prioritizes innovation and performance over everyday practicality. While it offers a reasonable luggage capacity of 470 liters, its low height, wide width, and aggressive stance may present challenges in daily urban driving and parking. The weight of 1550 kg is light for a performance coupe but still requires sophisticated suspension and handling systems to ensure comfort. Moreover, as a concept, it may lack some conveniences and regulatory approvals needed for routine road use, making it primarily an experimental platform rather than a daily driver.
