Both the Envision and QX30 have child safety locks to prevent children from opening the rear doors. The Envision has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The QX30’s child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.
To help make backing safer, the Envision Essence/Premium’s cross-path warning system uses wide-angle radar in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The QX30 doesn’t offer a cross-path warning system.
Both the Envision and the QX30 have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front seatbelt pretensioners, 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, crash mitigating brakes, lane departure warning systems, blind spot warning systems and around view monitors.
For its top level performance in all IIHS frontal, side, rear impact and roof-crush tests, with its optional front crash prevention system, and its available headlight’s “Acceptable” rating, the Insurance Institute for Highway Safety grants the Envision the rating of “Top Pick” for 2018, a rating granted to only 100 vehicles tested by the IIHS. The QX30 has not been tested, yet.
Buick pays for scheduled maintenance on the Envision for 2 years and 24,000 miles. Buick will pay for oil changes, lubrication and any other required maintenance (up to 2 oil changes). Infiniti doesn’t pay scheduled maintenance for the QX30.
There are almost 10 times as many Buick dealers as there are Infiniti dealers, which makes it much easier should you ever need service under the Envision’s warranty.
J.D. Power and Associates rated the Envision first among compact suvs in their 2018 Initial Quality Study. The QX30 isn’t in the top three in its category.
J.D. Power and Associates’ 2018 survey of the owners of three-year-old vehicles provides the long-term dependability 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 4 more problems per 100 vehicles, Infiniti is ranked fourth.
The Envision Premium’s standard 2.0 turbo 4 cyl. produces 44 more horsepower (252 vs. 208) and 37 lbs.-ft. more torque (295 vs. 258) than the QX30’s 2.0 turbo 4 cyl.
To lower fuel costs and make buying fuel easier, the Buick Envision uses regular unleaded gasoline (premium recommended on Envision Premium for maximum performance). The QX30 requires premium, which can cost 20 to 55 cents more per gallon.
The Envision has 4.1 gallons more fuel capacity than the QX30 FWD’s standard fuel tank (17.3 vs. 13.2 gallons), for longer range between fill-ups. The Envision has 2.5 gallons more fuel capacity than the QX30 AWD’s standard fuel tank (17.3 vs. 14.8 gallons).
In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Buick Envision higher (5 out of 10) than the Infiniti QX30 (3). This means the Envision produces up to 16.5 pounds less smog-producing pollutants than the QX30 every 15,000 miles.
A nine-speed automatic is standard on the Buick Envision Premium, for better acceleration and lower engine speed on the highway. Only a seven-speed automatic is available for the QX30.
The Envision has a standard easy tire fill system. When inflating the tires, the vehicle’s integrated tire pressure sensors keep track of the pressure as the tires fill and tell the driver when the tires are inflated to the proper pressure. The QX30 doesn’t offer vehicle monitored tire inflation.
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 QX30; 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’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 QX30 doesn’t offer drift compensation steering.
For a smoother ride and more stable handling, the Envision’s wheelbase is 2 inches longer than on the QX30 (108.3 inches vs. 106.3 inches).
The front grille of the Envision uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The QX30 doesn’t offer active grille shutters.
The Envision uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The QX30 doesn’t offer active noise cancellation.
The Envision has 11.8 cubic feet more passenger volume than the QX30 (100.6 vs. 88.8).
The Envision has 1.6 inches more front headroom, 2.3 inches more front hip room, 2.2 inches more front shoulder room, 1 inch more rear headroom, 4 inches more rear legroom, 4.1 inches more rear hip room and 2.7 inches more rear shoulder room than the QX30.
For enhanced passenger comfort on long trips the Envision’s rear seats recline. The QX30’s rear seats don’t recline.
The Envision has a much larger cargo volume with its rear seat up than the QX30 with its rear seat up (26.9 vs. 19.2 cubic feet). The Envision has a much larger cargo volume with its rear seat folded than the QX30 with its rear seat folded (57.3 vs. 34 cubic feet).
Pressing a switch automatically lowers the Envision’s rear seats, to make changing between passengers and cargo easier. The QX30 doesn’t offer automatic folding seats.
To make loading and unloading groceries and cargo easier when your hands are full, the Envision’s power liftgate can be opened or closed just by kicking your foot under the back bumper, leaving your hands completely free. The QX30 doesn’t offer a power or hands-free opening liftgate.
The Envision has a 1500 lbs. towing capacity. The QX30 has no towing capacity.
The Envision uses gas struts to support the hood for easier service access. The QX30 uses a prop rod to support its heavy hood. It takes two hands to open the hood and set the prop rod, the prop rod gets in the way during maintenance and service, and the prop rod could be knocked out, causing the heavy hood to fall on the person maintaining or servicing the car.
The Envision has a standard remote vehicle starting system, so the vehicle can be started from inside the driver's house. This allows the driver to comfortably warm up the engine before going out to the vehicle. The climate system will also automatically heat or cool the interior. The QX30 doesn’t offer a remote starting system.
The Envision Premium offers an optional heads-up display that projects speed and other key instrumentation readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The QX30 doesn’t offer a heads-up display.
The power windows standard on both the Envision and the QX30 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 QX30 prevents the driver from operating the other windows just as it does the other passengers.
The Envision’s front and rear power windows all lower 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 QX30’s rear power window switches have to be held the entire time to open them fully.
To improve rear visibility by keeping the rear window clear, the Envision has a standard rear fixed intermittent wiper with a full on position. The rear wiper standard on the QX30 only has an intermittent setting, so in a hard rain visibility isn’t as good.
To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the Envision has standard extendable sun visors. The QX30 doesn’t offer extendable visors.
The Envision has standard heated front seats. Heated front seats are only available on the QX30 Luxe/Sport/Essential. The Envision Essence/Premium also has standard heated rear seats to keep those passengers extremely comfortable in the winter. Heated rear seats aren’t available in the QX30.
Optional air-conditioned seats in the Envision Premium keep the driver and front passenger comfortable and take the sting out of hot seats in summer. The QX30 doesn’t offer air-conditioned seats.
On extremely cold winter days, the Envision Essence/Premium’s standard heated steering wheel provides comfort, allowing the driver to steer safely and comfortably before the vehicle heater warms up. The QX30 doesn’t offer a heated steering wheel.
The Envision Premium 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 QX30 doesn’t offer a house-current electrical outlet.
According to The Car Book by Jack Gillis, the Envision is less expensive to operate than the QX30 because typical repairs cost much less on the Envision than the QX30, including $296 less for a water pump, $76 less for a muffler, $166 less for fuel injection, $5 less for a timing belt/chain and $494 less for a power steering pump.
J.D. Power and Associates rated the Envision third among compact suvs in owner reported satisfaction. This includes how well the vehicle performs and satisfies its owner’s expectations. The QX30 isn’t in the top three.
The Buick Envision outsold the Infiniti QX30 by almost four to one during 2018.
