What the table shows
The two columns are a 2024 X3 and a 2024 X5, taken from the specification cards behind this site rather than from a manufacturer’s press release. The starting version of a shared model year is used on both sides, so the comparison is base against base.
- Power: the X5 is more powerful by 127 hp — 375 against 248, 51% more.
- Combined economy: the X5 is more economical by 1 mpg — 25 against 24, 4% more.
- Length: the X5 is longer by 8.7 in — 194.1 against 185.4, 5% more.
The X3 uses the B48, a 2.0-litre turbocharged four; the X5 the B58, a 3.0-litre turbocharged six. The X3 is all-wheel drive, the X5 rear-wheel drive.
Rows the table leaves blank are figures neither card carries. Torque, acceleration and top speed are not collected by any US government source and appear on this site only where an original factory brochure printed them, so they are missing more often on recent cars than on older ones.
