Key Differences
-
The X7 has better fuel economy
Few buyers will miss this one. The X7 brings 22 mpg to the table; the LX 600 brings 19 mpg. The X7 uses less fuel on the standard combined cycle, which matters most if you drive a lot.
-
The LX 600 has 81 lb-ft more torque
When it comes to torque, the LX 600 wins comfortably with 479 lb-ft against 398 lb-ft. More torque means stronger pulling from low speeds, which you feel when accelerating from a stop or climbing grades.
-
The LX 600 has 34 hp more power
It’s a small lead (409 hp versus 375 hp), but it’s real, and it goes to the LX 600. Power is only part of the story; weight, gearing and torque delivery shape how quick a car feels.
-
The X7 has better city fuel economy
It’s a lopsided result (20 mpg for the X7, 17 mpg for the LX 600) and one of the main reasons to choose between them. Hybrids often shine in the city, and the X7 has the better rating here.
-
The X7 has better highway fuel economy
The LX 600 isn’t far behind at 22 mpg, but the X7’s 24 mpg still comes out ahead. Speed, wind and load affect highway use a lot, but the official rating is a fair comparison point.
