2018 INFINITI QX80 VS. 2018 LEXUS GX | Competition INFINITI of Smithtown


The 2018 INFINITI QX80 and the 2018 Lexus GX are both impressive vehicles in terms of looks and performance. They have a plethora of amenities and luxurious trim and the Lexus GX has a number of off-road features. But which is the better choice for practical daily use?

Design & Style

Each crossover SUV is stylish with a very comfortable interior. In terms of space, the INFINITI edges out the Lexus GX slightly with more space for the hips and shoulders. The headroom is almost identical at 40 inches and both are equal in terms of the number of passengers they hold, at a total of 7. The INFINITI QX80 wins in terms of overall size dimensions, at 79.9 inches versus 74.2 for the Lexus. This means those that buy the INFINITI will also have more cargo areas, which matters for families or those who are routinely transporting lots of items.

Technology & Safety

This is an area where the two SUVs are evenly matched. Both are known for their advanced safety and technology features, with each incorporating disc rear brakes, a 4 wheel anti-brake system, and disc front brakes. The INFINITI QX80 does have a higher fuel capacity, at 26 gallons versus 23 gallons for the Lexus GX. Each vehicle utilizes rack-pinion steering.


In terms of trailering capacity, the INFINITI is much more powerful than the Lexus at 8500 pounds versus only 6500 pounds, but few drivers will likely take advantage of this feature. What they will take advantage of is the engine, and the QX80 shines at 413 torque at 4000 RPM, while the Lexus lags behind at only 329 torque at 3500 RPM. The INFINITI QX80 also boasts 400 horsepower at 5800 RPM while the Lexus has 301 horsepower at 5500 RPM. Both use a V-8 engine that is premium unleaded, but the Lexus GX does surpass the INFINITI in terms of fuel economy, at 15 miles to the gallon versus only 14 for the INFINITI. Also, because the Lexus GX is smaller than the QX80 this also makes it more agile and maneuverable.

The Bottom Line

Although the INFINITI QX80 edges out the Lexus GX in a number of key areas, where it doesn’t is the price. The QX80 is a whopping $60,000 whereas the Lexus GX can be purchased for about $50,000. That is a difference of $10,000 and will matter to those for who price is an issue. For those who prioritize performance, the INFINITI QX80 is flat out superior. More space, almost the same amenities and better performance!
