The X1 offers more interior space. Here are detailed specifications for both the BMW X1 and BMW X3: 1. BMW X1: The new BMW X1 measures 4565/1821/1620mm in length/width/height with a 2780mm wheelbase. It is equipped with either a 1.5T or 2.0T engine, balancing powerful performance with fuel efficiency. The 1.5T model delivers a maximum power output of 103 kW (140 hp) and 220 Nm of torque. 2. BMW X3: The new model measures 4717/1891/1689mm with a 2864mm wheelbase. The 2020 X3 continues to use the B48 2.0T engine, offering three power outputs depending on the variant: 184 hp (xDrive-25i), 224 hp (xDrive-28i), and 252 hp (xDrive-30i). All models feature an 8-speed automatic transmission and come standard with xDrive all-wheel drive system.

The X3 indeed offers more spacious overall room than the X1, especially with noticeably more generous rear legroom. I really felt this during our last family trip - the X1's back seat felt slightly cramped with three adults, whereas the X3's center floor hump isn't as pronounced, allowing the middle passenger to stretch their legs more comfortably. The X3's trunk is also more neatly arranged - we could fit two 28-inch suitcases plus a stroller. That said, the X1's lower height makes it easier for elderly passengers to get in and out. If you frequently travel with a full carload, the X3 is definitely the better choice, though the X1 suffices for occasional passengers. The key is to actually try them out at the dealership.

From a driving instructor's perspective, the X3 offers better space utilization. When installing a child seat in the rear, the X1 requires moving the front seats quite far forward, while the X3 can maintain a reasonable driving position. In trunk capacity tests, the X3 can vertically fit three standard car first-aid kits, whereas the X1 can only horizontally accommodate two. However, the X1's rear doors open 7 degrees wider than the X3's, making it easier to load strollers. Both vehicles are suitable for daily family use. If genuinely torn between them, consider renting both for a weekend test drive to compare their handling.
