INFINITI QX80 trim comparison
2026 INFINITI QX80 LUXE vs SPORT
The QX80 LUXE starts at $90,850 while the SPORT is $101,950. That $11,100 gap buys 5 meaningful differences.
The SPORT adds 4WD instead of RWD. If you deal with winter roads or need traction off-pavement, that could be worth $11,100 by itself. If not, the LUXE saves you the money.
The LUXE is the cleaner fit if RWD already covers the job. The SPORT only earns the extra money when 4WD is the reason you are shopping up.
If you are budgeting this move monthly, the jump from the LUXE to the SPORT is about $195/month on a 60-month loan at 6.5% APR with 10% down. That works out to roughly $11,700 more by the time interest is counted. The real question is whether 4WD changes your day-to-day use enough to justify paying above RWD.
Lock one trim, change the other side, and move through exact pair pages without resetting back to the full lineup every time.

The SPORT starts at $101,950 compared to $90,850 for the LUXE. That is a $11,100 difference, or approximately $195/month more on a 60-month loan.
Do the 2026 INFINITI QX80 LUXE and SPORT have the same engine?
Yes. Both use the 3.5L V6 Turbo producing 450 hp and 516 lb-ft of torque. The engine hardware does not change between these trims, so the real differences are in equipment and feature content.
Does the 2026 QX80 LUXE come with 4WD?
No. The LUXE comes standard with RWD while the SPORT has 4WD. This affects traction, fuel economy, and curb weight.
Is the 2026 INFINITI QX80 SPORT worth $11,100 more than the LUXE?
The $11,100 adds 4WD. Worth it if you need the traction. Not worth it if you drive on dry roads year-round.
Which 2026 INFINITI QX80 trim gets better fuel economy, the LUXE or the SPORT?
The LUXE is the more efficient of the two at 18 combined MPG, versus 17 for the other trim. That matters most if you are balancing running costs against the extra power, drivetrain, or comfort equipment tied to the pricier trim.
The Full Story Behind This Price Gap
Use the direct answer above for this exact matchup, then use these guides to understand whether you are really looking at a feature step-up, a package shuffle, or the point where the lineup starts changing in a meaningful way.
What $11,100 Gets You
