Interior, Space, and Cargo
This is where the two vehicles diverge most sharply. The EX90 is a genuine three-row SUV. Seven-seat and six-seat configurations are available across multiple trims, making it one of the few electric SUVs that can carry a full family without asking anyone to wait behind.
The BMW iX is a five-passenger vehicle. There is no third row.
Behind the second row, the iX holds 35.5 cu ft, which exceeds the EX90's 24.4 to 24.6 cu ft in that same position. That gap exists because the EX90's third row occupies rear floor space the iX dedicates entirely to cargo. Fold all rows and the EX90 reaches 73.5 to 75.4 cu ft depending on seat count, while the iX reaches 77.9 cu ft maximum.
Both vehicles include a front trunk (frunk). The EX90 frunk measures 1.6 cu ft, providing a useful spot for charging cables and small items.
