New 2025 Infiniti QX80 vs. Old QX80: All the Changes Side-By-Side

At last, an all-new Infiniti QX80 arrives for 2025. Infiniti’s flagship three-row SUV aims to spark a brand renaissance, wearing an exterior crafted in a new design language and an interior that offers many premium features. Given how outdated the previous QX80 was, the 2025 model didn't have to try hard to be a significant upgrade—the question is if the new QX80 is good enough to be a worthy contender among today’s luxury full-size three-row SUVs. Here are the main ways the new QX80 differs from its predecessor.

2025 Infiniti QX80 vs. Old QX80: Size

One thing that hasn’t changed about the QX80: Infiniti’s biggest SUV remains rather big. The 2025 QX80 rides on a 121.0-inch wheelbase, only 0.1 inch shorter than the outgoing model. However, overall length is 211.2 inches, exactly 1.0 inch more than before. Width on the 2025 QX80 is 83.3 inches, an increase from 79.9 inches. The new vehicle stands taller, at 76.6 to 77.9 inches including the roof rails depending on specification and setting for the air suspension, up from 75.8 inches on the old QX80. (We normally do not include roof rails in our exterior dimensions.)

2025 Infiniti QX80 vs. Old QX80: Engine and MPGs

For the new QX80, smaller means better when it comes to what’s under the hood. The old model used a 5.6-liter V-8 engine that produced 400 hp and 413 lb-ft of torque. It was attached to a seven-speed automatic transmission. The 2025 QX80 has an engine that’s downsized but considerably stronger. It’s a 3.5-liter twin-turbocharged V-6 that makes 450 hp and 516 lb-ft of torque, all sent through a nine-speed automatic transmission. As before, the 2025 QX80 is RWD as standard and offers or includes 4WD depending on trim.

Despite its smaller and more modern configuration, the new QX80 engine is barely more fuel efficient than before. It returns an estimated 16/20 mpg city/highway with RWD and 15/19 mpg with 4WD. That compares to 14/20 mpg with RWD and 13/19 mpg with 4WD from the outgoing V-8-powered model. Additionally, the new model’s fuel tank is 23.6 gallons, smaller than 26.0 gallons before. Maximum towing capacity remains unchanged at 8,500 pounds.

2025 Infiniti QX80 vs. Old QX80: Off-Road

Infiniti doesn’t position the QX80 as an off-road-oriented vehicle. Nevertheless, with its body-on-frame construction and available four-wheel drive, some enthusiasts will wonder how capable it is when the pavement ends. The new QX80 seems to have certain advantages for dirt driving compared to its predecessor. Ground clearance can go as high as 10.0 inches thanks to the newly available height-adjustable air suspension system, compared to 9.2 inches for the old QX80. Approach angle can be as much as 25.1 degrees, better than 20.9 degrees previously. Likewise, a departure angle of 25.6 degrees on the new QX80 represents an improvement from 22.3 degrees previously. A Snow mode primes the new QX80 for driving on slippery surfaces.

2025 Infiniti QX80 vs. Old QX80: Seats and Passenger Space

Like the previous model, the new QX80 has capacity for seven or eight occupants. That depends on whether the standard captain’s chairs or available three-across bench seat is equipped in the second row. Regardless, the third row has three seats.

Front-row legroom in the 2025 QX80 measures 43.8 inches, a generous increase from 39.6 inches before. Second-row legroom is down slightly, to 39.2 inches from 41.0 inches. However, third-row legroom sees a significant increase, now listing at 32.9 inches compared to just 28.8 inches in the outgoing model.

2025 Infiniti QX80 vs. Old QX80: Cargo Capacity

Although the new QX80 isn’t much larger outside than its predecessor, it provides a bit more space inside. With all three rows of seats upright, the 2025 QX80 has 22.0 cubic feet of cargo space, compared with 16.6 cubic feet before. Folding the third-row seat takes cargo space to 59.0 cubic feet, up from 49.6 cubic feet. Maximum cargo capacity with the second and third row seats folded measures 101.0 cubic feet in the 2025 QX80, an increase from 95.1 cubic feet.

2025 Infiniti QX80 vs. Old QX80: Technology Features

No surprise: The new QX80’s tech features make the old model seem even more outdated. The 2025 QX80 has dual 14.3-inch displays on its dashboard, one serving as the driver’s gauge cluster and the other as the infotainment touchscreen. The 2024 QX80 had a small display between analog gauges, plus a 12.3-inch infotainment touchscreen running Google built-in. Wireless Apple CarPlay carries over to the new model, but wireless Android Auto connectivity is a new addition. A separate 9.0-inch touchscreen handles climate control and drive mode functions. In the new model, an available head-up display and digital rearview mirror are firsts for the QX80.

Although both QX80 models offered a 360-degree camera, the 2025 version can provide additional camera perspectives such as an ultra-wide front view and a simulated transparent hood function. There’s also a selfie camera inside the cabin. A wireless charging pad is standard on both models, but the 2025 QX80 doubles the USB-C charge port count to eight, with those provided in all three rows of seats.

The old QX80 used Bose audio systems, with the standard setup comprising 13 speakers and the upgrade taking the count to 17 speakers. Now, the QX80 comes with Klipsch audio, with a 14-speaker system standard and a 24-speaker arrangement included on higher-end models.

2025 Infiniti QX80 vs. Old QX80: Safety and Driver Assist Features

The standard driver assist and active safety features on the old and new QX80 are fairly similar. Both include front automatic emergency braking, rear cross-traffic alert, blind-spot monitoring, lane departure warning, lane keep assist, adaptive cruise control, automatic high-beams, and front and rear parking sensors. Rather than a torque sensor, the steering wheel has a capacitive sensor to ensure the driver is keeping their hands where they should be when standard lane keep assist is active.

The 2025 QX80 offers Infiniti’s latest Pro Pilot Assist 2.1 system, which can provide hands-free driving capability on certain stretches of highway, given suitable conditions.

2025 Infiniti QX80 vs. Old QX80: Luxury Features

Infiniti made an effort to increase perceived luxury in the new QX80. The redesigned exterior features elaborate LED lights and pop-out door handles for a premium touch. In addition to the larger digital displays, the dashboard has a more modern appearance thanks to the push-button shifter and two-spoke steering wheel. Specific equipment varies depending on trim level, but what’s on offer is becoming of a new luxury SUV. Among the available features are 64-color adjustable interior ambient lighting, heated ventilated and massaging second-row seats, two-level heating for the third-row seats, and a panoramic moonroof. Most trim levels are equipped with an air suspension system and offer the ability to power-fold the second- and third-row seats from the main touchscreen.

2025 Infiniti QX80 vs. Old QX80: The Drive

By the end of its protracted production run, the outgoing QX80 felt old from behind the wheel. There just wasn’t any hiding its truck-based construction and engine. With an updated chassis, new engine, available air suspension, and a slew of modern amenities, the 2025 QX80 finally feels competitive with other luxury three-row SUVs.

2025 Infiniti QX80 vs. Old QX80: Price

The 2024 QX80 started with the Luxe RWD model priced at slightly more than $75,000 and topped out with the approximately $90,000 Sensory 4WD version. As things tend to go these days, the new 2025 QX80 is more expensive than the vehicle it replaces. The entry-level Pure RWD trim costs approximately $84,000, before moving to the $91,000 Luxe RWD model; 4WD is a $3,100 upgrade on both of those trims. Above that, the Sensory trim includes 4WD as standard and costs about $103,000. At the top of the range is the QX80 Autograph, which commands approximately $113,000.
