Key Differences
-
The LX 600 has better fuel economy
The Navigator isn’t far behind at 17 mpg, but the LX 600’s 19 mpg still comes out ahead. The LX 600 uses less fuel on the standard combined cycle, which matters most if you drive a lot.
-
The Navigator has 31 hp more power
A narrow win for the Navigator. With 440 hp to 409 hp, it’s the kind of difference that adds up rather than stands out. Power is only part of the story; weight, gearing and torque delivery shape how quick a car feels.
-
The Navigator has room for 8 seats
Close, but not identical: the Navigator lists 8 seats and the LX 600 lists 7 seats. Extra seats mean you can take more people along without taking a second car.
-
The Navigator has 700 lb more towing capacity
The gap on max towing is slim (8,700 lb against 8,000 lb), yet it tips toward the Navigator. If you tow regularly, the Navigator’s higher rating gives you more margin.
-
The Navigator has 31 lb-ft more torque
You may not notice this one every day, but the Navigator’s 510 lb-ft is a step ahead of the LX 600’s 479 lb-ft. The Navigator’s extra torque makes it more relaxed when fully loaded or towing.
