Compare the2025 Buick EnvistaVS 2025 Infiniti QX55

In a Vehicle-to-Vehicle Frontal Crash Prevention 2.0 test conducted by the Insurance Institute for Highway Safety (IIHS), the Buick Envista achieved a “Acceptable” rating - the second highest possible - for its performance in forward collision warning and automatic braking systems, demonstrating its excellent capabilities in preventing collisions. The Infiniti QX55 has not been tested.

Both the Envista and the QX55 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, rearview cameras, available blind spot warning systems and rear cross-path warning.

The National Highway Traffic Safety Administration does 35 MPH front crash tests on new vehicles. In this test, results indicate that the Buick Envista is safer than the Infiniti QX55:

New test not comparable to pre-2011 test results. More stars = Better. Lower test results = Better.

There are almost 5 times as many Buick dealers as there are Infiniti dealers, which makes it much easier should you ever need service under the Envista’s warranty.

To reliably start during all conditions and help handle large electrical loads, the Envista has a standard 760-amp battery. The QX55’s 720-amp battery isn’t as powerful.

J.D. Power and Associates’ 2024 Initial Quality Study of new car owners surveyed provide the statistics that show that Buick vehicles are better in initial quality than Infiniti vehicles. J.D. Power ranks Buick above average in initial quality. With 23 more problems per 100 vehicles, Infiniti is rated lower.

J.D. Power and Associates’ 2024 survey of the owners of three-year-old vehicles provides the statistics that show that Buick vehicles are more reliable than Infiniti vehicles. J.D. Power ranks Buick third in reliability, above the industry average. With 70 more problems per 100 vehicles, Infiniti is ranked 22nd.

On the EPA test cycle the Envista gets better fuel mileage than the QX55 (28 city/32 hwy vs. 22 city/28 hwy).

In heavy traffic or at stoplights the Envista’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. The engine is automatically restarted when the driver gets ready to move again. If the conditions warrant or the driver wishes, the system can be manually disabled at any time for the duration of a trip. The QX55 doesn’t offer an automatic engine start/stop system.

To lower fuel costs and make buying fuel easier, the Buick Envista uses regular unleaded gasoline. The QX55 requires premium, which can cost on average about 84.9 cents more per gallon.

The Envista has a standard cap-less fueling system. The fuel filler is automatically opened when the fuel nozzle is inserted and automatically closed when it’s removed. This eliminates the need to unscrew and replace the cap and it reduces fuel evaporation, which causes pollution. The QX55 doesn’t offer a cap-less fueling system.

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Buick Envista higher (6 out of 10) than the Infiniti QX55 (5). This means the Envista produces up to 6.9 pounds less smog-producing pollutants than the QX55 every 15,000 miles.

The Envista has a standard space-saver spare tire so you can replace a flat tire and drive to have the flat repaired or replaced. A spare tire isn’t available on the QX55; it requires you to depend on its run-flat tires, which limits mileage and speed before they are repaired. If a run-flat is damaged beyond repair by a road hazard your vehicle will have to be towed.

The Buick Envista may be more efficient, handle and accelerate better because it weighs about 950 to 1000 pounds less than the Infiniti QX55.

The Envista is 3.7 inches shorter than the QX55, making the Envista easier to handle, maneuver and park in tight spaces.

The front grille of the Envista uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The QX55 doesn’t offer active grille shutters.

The Envista has 2.3 inches more front legroom and .4 inches more rear headroom than the QX55.

The Envista can be flat towed on all four wheels (dinghy towed), allowing recreational vehicle owners to bring it with them on the road. When they reach their destination, the Envista can be unhitched and driven around locally. The QX55 can’t be towed flat on the ground.

The Envista’s instruments include an oil pressure gauge and a temperature gauge - which could save your engine! Often ‘idiot lights’ don’t warn you until damage has been done. The QX55 does not have an oil pressure gauge.

The power windows standard on both the Envista and the QX55 have locks to prevent small children from operating them. When the lock on the Envista is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The QX55 prevents the driver from operating the other windows just as it does the other passengers.

In case you lock your keys in your vehicle, or don’t have them with you, you can let yourself in using the Envista’s available exterior PIN entry system. The QX55 doesn’t offer an exterior PIN entry system, and its Infiniti Connection can’t unlock the doors if the vehicle doesn’t have cell phone reception or the driver can’t contact the service.

The Envista Avenir’s standard rear view mirror and optional side view mirrors have an automatic dimming feature. These mirrors can be set to automatically darken quickly when headlights shine on them, keeping following vehicles from blinding or distracting the driver. The QX55 has an automatic rear view mirror, but its side mirrors don’t dim.
