INFINITI QX80 vs Lexus LX 600 | Side-by-Side Comparison
The INFINITI QX80 and Lexus LX 600 compete in the ultra-luxury full-size SUV segment. Both deliver premium interiors, three-row seating, and commanding road presence. But they differ in power delivery, value proposition, and the dealership experience you get in Boerne.
Power & Performance
The QX80 steps up with a 3.5L twin-turbo V6 producing 450 horsepower and 516 lb-ft of torque. That power flows through an 9-speed automatic transmission. The Lexus LX 600 relies on a twin-turbo 3.4L V6 with 409 hp and 479 lb-ft – respectable numbers, but measurably less aggressive than the INFINITI.
The QX80’s turbocharged advantage shows up in acceleration and trailer pull. If you’re moving a boat to Lake Travis or towing equipment across Hill Country, the INFINITI’s extra muscle matters. The QX80 tows 8,500 lbs, matching the LX 600’s 8,000-lb capacity – a near tie in real-world towing, though the INFINITI’s power delivery gives you easier control on steep inclines.
Pricing & Value
The INFINITI QX80 starts at $83,750. The Lexus LX 600 Luxury starts at $117,000. That’s a $33,250 gap in base pricing. For buyers in Boerne and the Hill Country, the QX80 delivers comparable luxury with significantly better value.
The LX 600 Premium goes even higher at $117,000, and the hybrid LX 700h starts at $142,000. The Lexus name carries prestige in certain circles, but the INFINITI offers a smarter value equation without sacrificing quality.
Seating & Space
Both vehicles seat 7-8 passengers across three rows. The QX80 delivers 7-8 seating depending on configuration. The LX 600 seats 7 across. Both offer generous cargo space when rear rows fold, though the LX 600 edges the QX80 slightly in raw passenger volume. For families hauling kids’ sports equipment, friends on a Hill Country weekend, or extended family gatherings, both handle it equally well.
Interior & Luxury Features
The LX 600 shines here with ultra-refined materials, a quieter cabin, and Lexus’s reputation for meticulous assembly. The QX80 matches that quality with its own premium leather, wood trim, and thoughtful ergonomics. Both feature premium audio, multi-zone climate control, and advanced tech.
The real difference is refinement nuance. Lexus owners often cite quietness and interior feel. INFINITI owners appreciate the QX80’s performance edge paired with similar luxury. Neither vehicle will disappoint in comfort or materials.
Fuel Economy
The LX 600 returns 17 mpg city, 22 highway, 19 combined. The hybrid LX 700h achieves 19/22/20. INFINITI hasn’t published exact fuel economy for the QX80, but expect similar figures given both use 3.4-3.5L twin-turbo V6s. If fuel economy is critical, the LX 700h hybrid edges ahead – though you’ll pay $142,000+ for that benefit.

Frequently Asked Questions
Is the QX80 more reliable than the LX 600?
Both are built by Japanese manufacturers with strong track records. INFINITI and Lexus both earn top marks in reliability studies. The QX80’s 3.5L twin-turbo is proven in the INFINITI lineup, and Lexus’s 3.4L twin-turbo has an excellent reputation. Difference: minimal. Your service experience matters more – and that’s where INFINITI of Boerne pulls ahead with our local accolades and 70+ loaner fleet.
Does the QX80 really outpull the LX 600?
Yes. The QX80’s 450 hp versus the LX 600’s 409 hp translates to noticeably easier acceleration and trailer control, especially on inclines or at altitude. Both tow around 8,000-8,500 lbs, so real-world towing is comparable – but the INFINITI does it with more power in reserve. Test both on a loaded trailer to feel the difference.
Why does the LX 600 cost so much more?
Brand prestige and Lexus’s “luxury tax.” The LX sits atop Toyota’s luxury division, and buyers pay a premium for the badge and the meticulous refinement Lexus is known for. The INFINITI QX80 delivers nearly identical luxury at a lower entry price, which appeals to value-conscious luxury buyers. It’s not about one being better – it’s about what matters most to you.
