BMW’s iX4 marks the automaker’s first all-electric version of its long-running X4 crossover, blending a coupe-inspired profile with a performance-oriented approach rather than maximizing utility. The vehicle shares its underpinnings with the iX3, but its design adopts a lower roofline and standard M Sport trim, giving it a more aggressive stance. Although it uses the same battery and propulsion system as the iX3, the iX4’s range in the U.S. market is reduced to a maximum of 428 miles, six miles less than its sibling model.
The sloped roofline design, first introduced by BMW on the original X6 in 2008, has since become a widespread trend in the automotive industry. Manufacturers now frequently adopt this styling to attract buyers seeking a mix of SUV practicality and a sportier aesthetic. However, this design choice comes at a cost: the iX4’s cargo capacity is diminished. With the rear seats in an upright position, its trunk measures 17.3 cubic feet, roughly one cubic foot smaller than the iX3’s, while the vehicle’s overall height is reduced by 1.5 inches.
The iX4’s battery and fast-charging performance closely match those of the iX3 in the U.S., where both models feature an 112.2-kWh battery pack. This configuration delivers 463 horsepower and supports a peak DC charging rate of 400 kilowatts, enabling a 183-mile range gain in just 10 minutes of fast charging. In Europe, the base iX4 40 xDrive uses an 82.6-kWh battery, offering 396 miles of range and a slightly slower 300-kW charging speed.
BMW plans to release two variants of the iX4 in the U.S. market. The first, the iX4 50 xDrive, will arrive in March 2027 and will feature the standard battery and powertrain. Later in the lineup, the iX4 M60 xDrive will debut with 603 horsepower and a 0-60 mph acceleration time of 3.7 seconds. This high-performance model includes adaptive suspension, sport steering, and a limited-slip differential, though its range is expected to decrease further due to the increased power demands.
The iX4’s interior retains many features from the iX3, including a 17.9-inch central touchscreen, a 3D head-up display, and BMW’s Alexa-based voice assistant. The model also supports vehicle-to-load (V2L) and vehicle-to-home (V2H) power-sharing capabilities, though these require separate adapters.
