Lexus LX vs Infiniti QX80

The QX80 runs from $83,750 (Pure RWD) to $111,500 (Autograph 4WD), excluding a $2,190 destination charge. The LX opens at $108,050 for the gas LX 600 Premium and the LX 700h hybrid line carries it to $142,550, including the $1,550 delivery fee.

The bases differ, so read the shape rather than exact gaps: only the QX80's top Autograph trim reaches past the LX's floor. Most QX80 builds cost tens of thousands less than any LX — that is the frame of this whole comparison.

The QX80 is a three-row SUV in every build: captain's chairs are standard on all grades for seven seats, and a 40/20/40 second-row bench — optional on Pure and Luxe only — brings the count to eight. The LX's third row depends on configuration: grades sell as a 7-seat three-row, a 5-seat two-row, or the 4-seat Ultra Luxury two-row, and the $142,550 ceiling is that four-seat build.

The LX also offers no six-seat cabin — its seven-seat second row is always a bench, while the QX80 gives second-row captains as the default.

The QX80 publishes 32.9 in of third-row legroom and 36.2 of headroom against the LX's 31.1 and 35.24 — an advantage of 1.8 in of legroom and about an inch of headroom. The second row widens the gap: 39.2 in of legroom against 36.61.

Child-seat hardware separates them more sharply than the dimensions do. The QX80 provides one third-row lower-anchor set (sources disagree on which side) and three third-row top tethers; the LX's owner's manual provides neither lower anchors nor tethers in the third row. Both cover the third row with curtain airbags.

Behind the third row: QX80 20.4 cu ft, LX 11. Maximum: QX80 97.1, LX 64 — the smallest max-cargo figure in this dataset, a 33.1 cu ft gap. The QX80 publishes 56.3 cu ft behind the second row; Lexus publishes no comparable figure for the LX's three-row configuration, so that cell stays honestly empty.

With all seats up, the QX80 handles an airport run where the LX handles a grocery run. Folded, the difference is a full dresser's worth of volume.

The QX80 is rated 8,500 lb properly equipped; the LX is rated 8,000 lb with its Towing Package specification. Both are stout body-on-frame ratings — the QX80 keeps a 500 lb margin.

Neither leads the segment here (the dataset's ceiling is 9,096 lb), but either handles a large boat or camper without drama.

Lexus LX: The Lexus flagship badge, the LX 700h hybrid powertrain, or the four-seat Ultra Luxury cabin justifies paying more for less measured space. The third row should be occasional — it trails the QX80 on every third-row, second-row, and cargo figure, and carries no third-row child-seat anchors.

Infiniti QX80: The value case is lopsided: more third-row legroom and headroom, more cargo behind every row, an eight-seat option, a 500 lb towing advantage, and third-row child-seat hardware the LX lacks — with most of its trim ladder priced below the cheapest LX. Budget the $2,190 destination charge on top of its sticker.
