What the table shows
The two columns are a 2026 X5 and a 2026 X7, 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 X7 is more powerful by 67 hp — 375 against 308, 22% more.
- Combined economy: the X7 is more economical by 1 mpg — 23 against 22, 5% more.
- Length: the X7 is longer by 9.4 in — 203.5 against 194.1, 5% more.
Both use a 3.0-litre turbocharged six. Certification data does not name the engine family for both cards, so we cannot say from our own records whether that is one engine or two. Both drive all four wheels.
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.
