Compare the2023 Infiniti QX55VS 2023 Buick Envision

For enhanced safety, the front and rear seat shoulder belts of the Infiniti QX55 have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Buick Envision doesn’t offer pretensioners for its rear seat belts.

The Infiniti QX55 has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags helps prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The Envision doesn’t offer a front passenger side knee airbag.

Over 200 people are killed each year when backed over by motor vehicles. The QX55 has standard Rear Automatic Braking that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The Envision doesn’t offer backup collision prevention brakes.

To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the QX55. But it costs extra on the Envision.

Both the QX55 and the Envision have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning and available around view monitors.

The QX55 comes with a full 4-year/60,000-mile basic warranty, which covers the entire truck and includes 24-hour roadside assistance. The Envision’s 3-year/36,000-mile basic warranty expires 1 year or 24,000 miles sooner.

Infiniti’s powertrain warranty covers the QX55 1 year and 10,000 miles longer than Buick covers the Envision. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the Envision ends after only 5 years or 60,000 miles.

The QX55 has a standard continuously variable transmission (CVT). With no “steps” between gears, it can keep the engine at the most efficient speed for fuel economy, or keep it at its peak horsepower indefinitely for maximum acceleration. The Envision doesn’t offer a CVT.

For better stopping power the QX55’s front brake rotors are larger than those on the Envision:

For better traction, the QX55 has larger tires than the Envision (255/45R20 vs. 235/60R18). The QX55’s tires are larger than the largest tires available on the Envision (255/45R20 vs. 245/45R20).

The QX55’s tires provide better handling because they have a lower 45 series profile (height to width ratio) that provides a stiffer sidewall than the Envision’s standard 60 series tires.

For better ride, handling and brake cooling the QX55 has standard 20-inch wheels. Smaller 18-inch wheels are standard on the Envision.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires standard on the QX55 can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The Envision doesn’t offer run-flat tires.

The QX55 has vehicle speed sensitive variable-assist power steering, for low-effort parking, better control at highway speeds and during hard cornering, and a better feel of the road. The Envision doesn’t offer variable-assist power steering.

For better handling and stability, the track (width between the wheels) on the QX55 is 1.1 inches wider in the front and .5 inches wider in the rear than on the Envision.

Pulling a handle automatically lowers the QX55’s rear seats, to make changing between passengers and cargo easier. The Envision doesn’t offer automatic folding seats.

The QX55’s front and rear power windows all open or close with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside of the car. The Envision’s rear power window switches have to be held the entire time to close them fully.

If the windows are left open on the QX55 the driver can close them all at the outside door handle. On a hot day the driver can lower the windows from a distance using the keyless remote. The driver of the Envision can only close the windows from inside the vehicle, with the ignition on.

The QX55 has a standard locking fuel door with a remote release located convenient to the driver. A locking fuel door helps prevent fuel theft and vandalism, such as sugar in the tank. The Envision doesn’t offer a locking fuel door.

The QX55’s standard speed-sensitive wipers speed up when the vehicle does, so that the driver doesn’t have to continually adjust the speed of the wipers. The Envision’s standard manually variable intermittent wipers have to be constantly adjusted.
