INFINITI QX80 trim comparison
2026 INFINITI QX80 SPORT vs AUTOGRAPH
The QX80 SPORT starts at $101,950 while the AUTOGRAPH is $111,500. That $9,550 gap buys 2 meaningful differences.
$9,550 more is ~$168/month. The question is whether the added equipment will matter to you every week.
Stay with the SPORT if keeping roughly $168/month in your budget matters. Step up to the AUTOGRAPH only if you want the nicer equipment factory-installed and under warranty. That is the real decision hiding inside this $9,550 trim jump.
Think about this as a monthly tradeoff, not just a sticker gap. The AUTOGRAPH adds about $168/month on a typical 60-month loan, or around $10,080 more overall with interest. Luxury-trim buyers usually care less about the raw payment delta and more about whether the upgrade changes comfort, capability, or overall feel.
