On the EPA test cycle the Envision gets better mileage than the QX55:

An engine control system that can shut down some of the engine’s cylinders helps improve the Envision’s fuel efficiency. The QX55 doesn’t offer a system that can shut down part of the engine.

In heavy traffic or at stoplights the Envision’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 Envision uses regular unleaded gasoline (mid-grade octane recommended for maximum performance). The QX55 requires premium, which can cost 5 to 40 cents more per gallon.

The Envision 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 Envision higher (7 out of 10) than the Infiniti QX55 (6). This means the Envision produces up to 1.1 pounds less smog-producing pollutants than the QX55 every 15,000 miles.

The Envision 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 Envision offers an available continuously variable suspension system. Using sensors on steering angle, speed and other driver inputs, the shocks soften to improve ride, or stiffen when appropriate to aid handling on tricky roads or off-road. The QX55’s suspension doesn’t offer adjustable shock absorbers.

The Envision’s drift compensation steering can automatically compensate for road conditions which would cause the vehicle to drift from side to side, helping the driver to keep the vehicle straight more easily. The QX55 doesn’t offer drift compensation steering.

The Buick Envision may be more efficient, handle and accelerate better because it weighs about 200 to 400 pounds less than the Infiniti QX55.

The Envision is 3.8 inches shorter than the QX55, making the Envision easier to handle, maneuver and park in tight spaces.

The Envision has .8 inches more front legroom, 2 inches more rear headroom and .6 inches more rear legroom than the QX55.

The Envision has a 1500 lbs. towing capacity. The QX55 has no towing capacity.

Standard Trailer Sway Control (TSC) on the Envision uses the StabiliTrak® sensors to detect trailer sway, then uses individual brakes to counteract any swaying and help keep the tow vehicle and trailer steady. The QX55 doesn’t offer electronic trailer sway control.

J.D. Power and Associates surveys of service recipients show that Buick service is better than Infiniti. J.D. Power ranks Buick fifth in service department satisfaction. With a 10% lower rating, Infiniti is ranked 9th.

The power windows standard on both the Envision and the QX55 have locks to prevent small children from operating them. When the lock on the Envision 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.

The Envision’s standard rear and 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.

Both the Envision and the QX55 offer available heated front seats. The Envision Avenir also offers optional heated rear seats to keep those passengers extremely comfortable in the winter. Heated rear seats aren’t available in the QX55.

The Envision Avenir offers optional massaging front seats in order to maximize comfort and eliminate fatigue on long trips. Massaging seats aren’t available in the QX55.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Buick Envision Avenir has a standard wireless phone charging system (Qi) in the center console. The QX55 doesn’t offer wireless personal charging.

The Envision Avenir has a 115-volt a/c outlet on the center console, allowing you to recharge a laptop or run small household appliances without special adapters that can break or get misplaced. The QX55 doesn’t offer a house-current electrical outlet.

The Envision Avenir’s Enhanced Automatic Park Assist can parallel park or back into a parking spot by itself, starting and stopping automatically, with the driver only responsible for switching from reverse to drive. The QX55 doesn’t offer an automated parking system.
