2025 AITO M5 Ultra (facelift 2025) Dimensions, Size & Specs

The curb weight of the AITO M5 Ultra ranges between 2220 kg and 2335 kg (approximately 4892 to 5144 lbs), depending on specific configurations such as tire size, rim choice, and optional equipment. This weight bracket is typical for mid-to-large SUVs with advanced powertrains and technology packages. The weight affects dynamics such as acceleration, braking, and fuel efficiency; a heavier vehicle can provide a more planted and stable ride but may consume more energy. The M5 Ultra's engineering counters this with optimized chassis tuning and powertrain efficiency to deliver a balanced driving experience that emphasizes comfort without sacrificing performance.

The AITO M5 Ultra offers rim sizes of 19 and 20 inches, paired with tire dimensions of 255/50 R19 and 255/45 R20 respectively. Larger rims like the 20-inch option typically enhance the car's sporty appearance and can offer improved cornering precision due to lower-profile tires (255/45 R20). However, they might slightly reduce ride comfort on rough road surfaces. The 19-inch rims with 255/50 tires provide a taller sidewall which can better absorb road irregularities, thus improving overall ride comfort. Customers can choose based on their preference for sportiness or comfort.

The AITO M5 Ultra's dimensions — 4785 mm (188.4 inches) in length, 1930 mm (75.98 inches) in width, and about 1625 mm (63.98 inches) in height — generally allow it to fit within most standard residential garages. Typical single-car garages have dimensions of roughly 2440 mm (8 feet) in width and 4877 mm (16 feet) in depth, so while the M5 Ultra closely approaches these limits, careful parking is required, especially for the width which leaves about 510 mm (20 inches) clearance on either side if the garage is exactly 2440 mm wide. Owners in tighter spaces should ensure additional room for opening doors and movement around the vehicle.

Compared to the earlier M5 generation, the M5 Ultra facelift introduced in 2025 maintains very similar overall dimensions, preserving its 4785 mm (188.4 inches) length and 1930 mm (75.98 inches) width, with minor tweaks in height which now varies between 1620 and 1625 mm (63.78 to 63.98 inches). These subtle changes reflect design refinements aimed at enhancing aerodynamics and interior comfort without compromising the spaciousness and road presence that characterized its predecessor. Additionally, vehicle weight has seen a slight increase due to added features and updated technology, which may translate to improved safety and comfort.

While exact interior dimensions are not specified, the exterior size of the AITO M5 Ultra — almost 4.8 meters long and 1.93 meters wide — supports a roomy cabin layout typical for SUVs in this segment. The generous width facilitates ample shoulder room for passengers in both front and rear seats, while the length ensures comfortable legroom and headroom, likely augmented by the vehicle’s height of approximately 1.62 meters. Cargo space is expected to be competitive, benefiting from efficient packaging despite the vehicle's sizable curb weight. This balance allows the M5 Ultra to serve both family and utility needs effectively.

The AITO M5 Ultra competes in the midsize SUV segment, where competitors typically range from 4700-4900 mm (185-193 inches) in length and 1850-1950 mm (73-77 inches) in width. At 4785 mm (188.4 inches) long and 1930 mm (75.98 inches) wide, the M5 Ultra is squarely in the midsize category with a slightly above-average width, providing an imposing road presence and spacious cabin. Its curb weight between 2220-2335 kg (4892-5144 lbs) tends toward the heavier side, reflecting its advanced technology, safety features, and powertrain setup, which may contrast with lighter rivals that prioritize fuel efficiency but possibly sacrifice refinement or equipment levels.

The AITO M5 Ultra's height ranges from 1620 mm to 1625 mm (63.78 to 63.98 inches), a small variation influenced by the choice of suspension setup, trim levels, or optional features such as roof rails or tire and rim combinations. For example, the different rim sizes (19 vs 20 inches) paired with respective tire profiles can slightly affect the vehicle's ride height. This minor height adjustment may influence entry and exit ease, aerodynamic performance, or the vehicle’s center of gravity, thereby impacting handling and comfort subtly.

The 2025 facelift of the AITO M5 Ultra brought a range of design updates and technological enhancements aimed at refreshing the model’s appeal and improving its competitiveness. While retaining the core dimensions, the facelift incorporated refined exterior styling cues such as updated front and rear light designs, a more aerodynamic body shape, and improved material quality. Technological upgrades likely include enhanced infotainment systems, advanced driver-assistance features, and possible powertrain optimizations that improve efficiency and driving dynamics. These changes collectively create a more modern and comfortable SUV experience.

The AITO M5 Ultra offers 19-inch and 20-inch wheel options fitted with 255/50 R19 and 255/45 R20 tires respectively, both providing good all-around performance. The 19-inch tire setup with a taller sidewall offers better cushioning and comfort over rough or uneven surfaces, making it suitable for everyday urban driving and light off-road conditions. The 20-inch setup has lower-profile tires that enhance handling precision and responsiveness, ideal for drivers prioritizing sporty on-road dynamics. However, both tire types are optimized for typical SUV use, and for extreme off-road or winter conditions, specialized tires might be recommended.
