Key Differences
-
The XM has 383 hp more power
Of all the specs we compared, this is one where the XM makes its strongest case: 644 hp against 261 hp. More power helps with merging, overtaking and climbing hills, especially with passengers and luggage on board.
-
The Q7 has better fuel economy
The Q7 clearly leads on fuel economy (combined), and 22 mpg versus 14 mpg is a difference that reaches well beyond the spec sheet. Official figures rarely match real-world driving exactly, but the ranking between two cars tends to hold.
-
The Q7 has room for 7 seats
On seats, the Q7 posts 7 seats against 5 seats for the XM, a gap big enough to feel in everyday use. Extra seats mean you can take more people along without taking a second car.
-
The XM has 317 lb-ft more torque
This is one of the widest gaps in the whole comparison: 590 lb-ft for the XM versus 273 lb-ft for the Q7. The XM’s extra torque makes it more relaxed when fully loaded or towing.
-
The Q7 has better city fuel economy
The XM lists 12 mpg; the Q7 comes in at 20 mpg. That’s not a rounding error. In town, driving style has a big effect, but the Q7 starts from a better baseline.
