2026 BMW iX3 (NA5) Dimensions, Size & Specs

The curb weight of the 2026 BMW iX3 (NA5) is 2285 kg (5039 lbs), which reflects its solid construction and battery pack weight as a fully electric SUV. The maximum gross weight is 2825 kg (6229 lbs), allowing the vehicle to carry passengers and cargo comfortably within safety limits. While the heavier weight compared to internal combustion models might slightly impact acceleration and handling agility, BMW has engineered the iX3 to maintain responsive driving dynamics through balanced weight distribution and advanced suspension tuning. The weight also contributes to a stable ride and enhanced safety, while the electric powertrain ensures efficient energy use.

The 2026 BMW iX3 offers a practical luggage capacity of 520 liters (about 18.4 cubic feet) when the rear seats are upright, which is competitive within its class for daily errands or weekend trips. Folding down the rear seats significantly expands the cargo space to 1750 liters (61.8 cubic feet), accommodating larger items such as bicycles, bulky sports equipment, or multiple suitcases. This versatile storage capacity makes the iX3 a practical choice for families and active lifestyles, providing flexibility without compromising passenger comfort.

A standard residential garage typically measures around 2440 mm (8 feet) in width and 4877 mm (16 feet) in length. The BMW iX3's length of 4782 mm (188.2 inches) fits comfortably within the average garage length. However, the width of 1895 mm (74.6 inches) plus the side mirrors extending to 2093 mm (82.4 inches) means one must consider mirror folding to easily fit into a standard single garage space. Most users will find that folding mirrors is essential for comfortable entry and exit without risking damage, especially in narrower garages or tight spaces.

The iX3 provides a ground clearance of 176 mm (6.9 inches), which offers a good balance between SUV practicality and accessibility. This clearance allows the vehicle to handle uneven urban roads, speed bumps, and moderate gravel or dirt paths confidently without scraping the undercarriage. It's sufficient for everyday driving conditions, though it's not designed for hardcore off-roading. The 176 mm ground clearance contributes to the smooth SUV ride and a slightly elevated driver position, enhancing visibility and driver confidence.

The BMW iX3 comes equipped with 20-inch rims sized at 8.5J x 20, paired with tire dimensions of 255/45 R20. The large, wide tires provide excellent road grip and stability, improving handling and braking performance, especially important for an electric SUV's instant torque delivery. However, 20-inch wheels with relatively low-profile tires might slightly reduce ride comfort compared to smaller wheels due to less tire sidewall cushioning over bumps. Nevertheless, BMW's suspension tuning is aimed at balancing sporty handling with enough comfort for everyday commutes and longer drives, making this a well-rounded setup.

The 2026 BMW iX3 (NA5) continues the lineage of the original iX3 but features slight dimensional refinements to improve interior space, aerodynamics, and overall presence. Compared to the first-generation iX3, the NA5 typically maintains a similar footprint with minor increases in length and width to accommodate updated battery technology and interior comfort improvements. These changes ensure better passenger space and cargo versatility without compromising the familiar driving dynamics that made the original well-regarded. The modernized styling and technological upgrades also contribute to its appeal over its predecessor.

When compared to competitors like the Audi Q4 e-tron, Mercedes-Benz EQC, or Volvo XC40 Recharge, the 2026 BMW iX3 (NA5) stands out for its slightly larger length (4782 mm / 188.2 in) and comparable width (1895 mm / 74.6 in, excluding mirrors). This positioning gives it a marginally more spacious interior and increased cargo volume than some rivals, which often hover in the sub-4.7 meter range. The iX3's ground clearance and balanced weight are also competitive, offering a good mix of urban usability and open-road confidence. Its size is ideal for buyers seeking a midsize electric SUV with premium features and a strong road presence.

The 2026 BMW iX3 has a maximum roof load capacity of 75 kg (165 lbs). This rating means the vehicle can safely support roof racks or carriers designed for bicycles, luggage boxes, or sports equipment up to this weight limit. It's important to adhere to this threshold to preserve vehicle handling characteristics and safety. BMW's roof rails are typically compatible with a range of aftermarket and OEM accessories, making the iX3 versatile for users requiring extra cargo space for activities, travel, or outdoor gear.

The 2026 BMW iX3 (NA5) represents BMW’s continued commitment to fully electric SUVs, combining sustainable electric powertrain technology with the brand's signature driving dynamics and premium comfort. Its production starting from 2025 features advancements in battery technology for longer range and optimized energy efficiency. The vehicle includes spacious interior design, intuitive infotainment, and a host of driver assistance systems. With robust dimensions considering its midsize SUV category, the iX3 NA5 offers a blend of practicality, luxury, and environmental responsibility, appealing to eco-conscious drivers who desire BMW’s performance heritage.
