Safety

For enhanced safety, the front and rear seat shoulder belts of the Infiniti QX30 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 the rear seat belts.

Both the QX30 and the Envision have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front wheel drive, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available all wheel drive, lane departure warning systems and around view monitors.

Warranty

The QX30 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 4-year/50,000-mile basic warranty expires 10,000 miles sooner.

The QX30’s corrosion warranty is 1 year longer than the Envision’s (7 vs. 6 years).

J.D. Power and Associates’ 2018 Initial Quality Study of new car owners surveyed provide the statistics that show that Infiniti vehicles are better in initial quality than Buick vehicles. J.D. Power ranks Infiniti 14th in initial quality, above the industry average. With 3 more problems per 100 vehicles, Buick is ranked 16th, below the industry average.

From surveys of all its subscribers, Consumer Reports’ December 2018 Auto Issue reports that Infiniti vehicles are more reliable than Buick vehicles. Consumer Reports ranks Infiniti 13 places higher in reliability than Buick.

The QX30’s 2.0 turbo 4 cyl. produces 11 more horsepower (208 vs. 197) and 66 lbs.-ft. more torque (258 vs. 192) than the Envision’s standard 2.5 DOHC 4 cyl.

Motor Trend

Tires and Wheels

For better traction, the QX30 has larger tires than the Envision (235/50R18 vs. 225/60R18).

The QX30’s standard tires provide better handling because they have a lower 50 series profile (height to width ratio) that provides a stiffer sidewall than the Envision’s standard 60 series tires. The QX30’s optional tires have a lower 45 series profile than the Envision Premium’s 50 series tires.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires standard on the QX30 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.

Suspension and Handling

The QX30 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.

The QX30 Sport handles at .88 G’s, while the Envision Premium pulls only .81 G’s of cornering force in a Motor Trend skidpad test.

The QX30 Sport executes Motor Trend’s “Figure Eight” maneuver 1.4 seconds quicker than the Envision Premium (26.1 seconds @ .71 average G’s vs. 27.5 seconds @ .63 average G’s).

Chassis

The Infiniti QX30 may be more efficient, handle and accelerate better because it weighs about 450 to 600 pounds less than the Buick Envision.

The QX30 is 9.5 inches shorter than the Envision, making the QX30 easier to handle, maneuver and park in tight spaces.

The QX30 is 8.8 inches shorter in height than the Envision, making the QX30 much easier to wash and garage and drive (lower center of gravity).

Cargo Capacity

A standard locking glovebox (which can’t be accessed with the valet key) keeps your small valuables safer in the QX30. The Envision doesn’t offer locking storage for small valuables.

Servicing Ease

J.D. Power and Associates surveys of service recipients show that Infiniti service is better than Buick. J.D. Power ranks Infiniti first in service department satisfaction. With a 26% lower rating, Buick is ranked 9th.

Ergonomics

Unlike the driver-only memory system in the Envision Essence/Premium, the QX30 Luxe/Sport/Essential has standard driver and passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat and outside mirror angle and the front passenger seat also adjusts to the new passenger’s preset preferences.

The QX30’s front power windows 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 front passenger window doesn’t close automatically.

If the windows are left open on the QX30 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 operate the windows from inside the vehicle, with the ignition on.

The QX30 has a standard locking fuel door with a remote release located convenient to the driver. A locking fuel door helps prevent vandalism, such as sugar in the tank and fuel theft. The Envision doesn’t offer a locking fuel door.

Heated windshield washer nozzles are standard on the QX30 Sport/Essential to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The Envision doesn’t offer heated windshield washer nozzles.

To help drivers see further while navigating curves, the QX30 Sport/Essential has standard adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle. The Envision doesn’t offer cornering lights.

Economic Advantages

Insurance will cost less for the QX30 owner. The Car Book by Jack Gillis rates the QX30 with a number “5” insurance rate while the Envision is rated higher at a number “8” rate.

According to The Car Book by Jack Gillis, the QX30 is less expensive to operate than the Envision because it costs $450 less to do the manufacturer’s suggested maintenance for 50,000 miles. Typical repairs cost much less on the QX30 than the Envision, including $106 less for front brake pads, $5 less for a starter, $23 less for a fuel pump and $468 less for front struts.
