The two are within 4 mm on width, so neither is meaningfully easier to thread into a tight space. In a standard 2,400 mm bay that leaves about 509 mm of total clearance for the BMW iX3 and about 505 mm of total clearance for the Lexus RZ. The Lexus RZ also turns in a 0.9 m tighter circle, which helps with U-turns and multi-storey ramps.
