2026 Hyundai IONIQ 9 Dimensions, Size & Specs

The Hyundai IONIQ 9 offers a generous luggage capacity of 620 liters (21.9 cubic feet) with all seats in use, accommodating daily needs and luggage for trips. When the rear seats are folded down, the cargo volume dramatically increases to 2461 liters (86.9 cubic feet), making it highly versatile for transporting large items, equipment, or bulkier gear. This flexible storage solution enhances the vehicle’s utility for different lifestyle needs.

With a length of 5060 mm (199.2 inches) and width of 1980 mm (77.9 inches), the Hyundai IONIQ 9 is relatively large compared to many conventional vehicles. Standard residential garage sizes usually range around 5486 mm (216 inches) in depth and 2743 mm (108 inches) in width. Therefore, the IONIQ 9 will fit inside most standard garages but requires careful maneuvering due to its width and length. Owners with smaller or single-car garages should verify measurements to ensure comfortable access and parking.

The Hyundai IONIQ 9 has a ground clearance of 175 mm (6.9 inches), which strikes a practical balance for an electric SUV. This clearance is sufficient for typical urban roads, rougher city surfaces, and light off-road conditions like gravel or uneven terrain. It prevents undercarriage damage while maintaining a stable, comfortable ride height that aids in driver visibility and maneuverability. However, for serious off-roading, a higher ground clearance might be preferred.

The Hyundai IONIQ 9 offers a range of rim sizes: 19, 20, and 21 inches. Corresponding tire sizes include 255/60 R19, 275/50 R20, and 285/45 R21. Larger rims and wider tires (like the 21-inch with 285 mm width) provide improved handling and road grip, enhancing performance and cornering stability. However, they might slightly reduce ride comfort over rough surfaces compared to smaller rims. Consumers can choose based on their preference for sportiness, comfort, or aesthetic appeal.

The Hyundai IONIQ 9 is a new generation SUV introduced in 2025 with no direct predecessor under the 'IONIQ 9' model name, as it represents a new flagship electric SUV in Hyundai’s lineup. Compared to previous IONIQ models like the IONIQ 5 and IONIQ 6, the IONIQ 9 is significantly larger and more spacious, designed to compete in the full-size electric SUV market. This increase in size offers additional passenger comfort, cargo space, and advanced features, marking an evolution in Hyundai’s electric vehicle strategy.

The Hyundai IONIQ 9, measuring 5060 mm long and 1980 mm wide, aligns closely with other full-size electric SUVs like the Tesla Model X and Rivian R1S. While the IONIQ 9 offers competitive dimensions offering spacious interiors and large cargo capacity, it often provides more versatile luggage space with rear seats folded, at 2461 liters. Its ground clearance and wheel options also match or exceed competitors, making it a strong contender for those seeking a large, premium electric SUV balancing luxury, technology, and utility.

The dimensions of the IONIQ 9 allow for a spacious interior cabin that comfortably accommodates adults in all seating positions. With a width of 1980 mm (77.9 inches) and height of 1790 mm (70.5 inches), passengers enjoy ample shoulder and headroom. The extended length also contributes to generous legroom, particularly in the rear seats. Combined with the flexible cargo space, the IONIQ 9 is ideal for long trips, family outings, or transporting multiple passengers with luggage effortlessly.

The IONIQ 9’s large exterior dimensions are cleverly utilized to maximize interior volume and storage versatility. The rear seats fold flat to expand cargo space from 620 liters to an impressive 2461 liters, accommodating large gear, furniture, or sports equipment. The ride height of 175 mm (6.9 inches) ensures ease of entry and exit while aiding in urban and light off-road driving scenarios. The broad track width enabled by the 1980 mm width also enhances stability and handling, making it both practical and dynamic.

While the Hyundai IONIQ 9 is a sizable SUV at 5060 mm (199.2 inches) long and 1980 mm (77.9 inches) wide, it is designed with modern technology that aids urban driving, such as advanced parking sensors and maneuverability features. Its ground clearance supports comfort over typical city road imperfections. However, drivers should be mindful of its size when navigating narrow streets or tight parking spaces. Overall, those needing a large electric SUV for city use will find the IONIQ 9 manageable with some spatial awareness.
