In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the Envision are reminded to check the back seat if they opened the rear door before starting out. The Q3 doesn't offer a back seat reminder.

Over 200 people are killed each year when backed over by motor vehicles. The Envision has standard Reverse Automatic Braking that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The Q3 doesn't offer automatic braking for stationary objects directly to the rear.

Both the Envision and the Q3 have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, all wheel drive, 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 front parking sensors.

The National Highway Traffic Safety Administration does 35 MPH front crash tests on new vehicles. In this test, results indicate that the Buick Envision is safer than the Audi Q3:

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

The National Highway Traffic Safety Administration does side impact tests on new vehicles. In this test, which crashes the vehicle into a flat barrier at 38.5 MPH and into a post at 20 MPH, results indicate that the Buick Envision is safer than the Audi Q3:

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

Buick's powertrain warranty covers the Envision 1 year and 10,000 miles longer than Audi covers the Q3. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 5 years or 60,000 miles. Coverage on the Q3 ends after only 4 years or 50,000 miles.

There are over 3 times as many Buick dealers as there are Audi dealers, which makes it much easier should you ever need service under the Envision's warranty.

The Envision has a standard “limp home system” to keep drivers from being stranded if most or all of the engine's coolant is lost. The engine will reduce its power and light a warning lamp on the dashboard so the driver can get to a service station for repairs. The Q3 doesn't offer a lost coolant limp home mode, so a coolant leak could strand you or seriously damage the truck's engine.

On the EPA test cycle the Envision gets better fuel mileage than the Q3 45 TFSI (22 city/28 hwy vs. 20 city/28 hwy).

An engine control system that can shut down some of the engine's cylinders helps improve the Envision's fuel efficiency. The Q3 doesn't offer a system that can shut down part of the engine.

To lower fuel costs and make buying fuel easier, the Buick Envision uses regular unleaded gasoline. The Q3 requires premium for maximum efficiency, which can cost on average about 84.9 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 Q3 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 (6 out of 10) than the Audi Q3 (5 to 6). This means the Envision produces up to 6.9 pounds less smog-producing pollutants than the Q3 every 15,000 miles.

A nine-speed automatic is standard on the Buick Envision, for better acceleration and lower engine speed on the highway. Only an eight-speed automatic is available for the Q3.

The Envision stops shorter than the Q3:

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 Q3'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 Q3 doesn't offer drift compensation steering.

For a smoother ride and more stable handling, the Envision's wheelbase is 3.9 inches longer than on the Q3 (109.4 inches vs. 105.5 inches).

For better handling and stability, the track (width between the wheels) on the Envision is 1.1 inches wider in the front and 1.4 inches wider in the rear than on the Q3.

For better maneuverability, the Envision's turning circle is .7 feet tighter than the Q3's (38 feet vs. 38.7 feet).

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 Q3 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 Q3 doesn't offer active noise cancellation.

The Envision has 16.4 cubic feet more passenger volume than the Q3 (100.4 vs. 84).

The Envision has .4 inches more front legroom, 1.3 inches more rear headroom, 3.2 inches more rear legroom and .8 inches more rear shoulder room than the Q3.

The Envision has a much larger cargo volume with its rear seat up than the Q3 with its rear seat up (25.2 vs. 23.7 cubic feet). The Envision has a much larger cargo volume with its rear seat folded than the Q3 with its rear seat folded (52.7 vs. 48 cubic feet).

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 Q3 doesn't offer electronic trailer sway control.

J.D. Power and Associates surveys of service recipients show that Buick service is better than Audi. J.D. Power ranks Buick 9th in service department satisfaction (above the industry average). With an 8% lower rating, Audi is ranked 18th.

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 Q3 doesn't offer a remote starting system.

The Envision's standard easy entry system glides the driver's seat back, making it easier for the driver to get in and out. The Q3 doesn't offer an easy entry system.

The Envision'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 Q3 does not have an oil pressure gauge.

The Envision has a standard heads-up display that projects speed, tachometer, navigation instruction, infotainment and driver assistance information readouts in front of the driver's line of sight, allowing drivers to view information without diverting their eyes from the road. The Q3 doesn't offer a heads-up display.

The Envision has standard Keyless Access that allows you to unlock the doors from any outside door handle, unlock the cargo door, and start the engine, all without removing the key from the pocket or purse. The Audi Advanced Key costs extra on the Q3.

The Envision's power window, power lock, power mirror and cruise control switches are lit from behind, making them plainly visible and easier to operate at night. The Q3's cruise control switches are unlit, making them difficult to find at night and operate safely.

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 Q3 only has an intermittent setting, so in a hard rain visibility isn't as good.

The Q3 Premium Plus' cornering lamps activate a lamp on the front corner when the turn signal is activated. The Envision's standard adaptive cornering lights turn the actual headlight unit up to several degrees, depending on steering wheel angle and vehicle speed. This lights a significant distance into corners at any speed.

When the Envision is put in reverse, both rearview mirrors tilt from their original position. This gives the driver a better view of the curb during parallel parking maneuvers. Shifting out of reverse puts the mirrors into their original positions. The Q3's mirrors don't automatically adjust for backing.

Both the Envision and the Q3 offer available heated front seats. The Envision Avenir also has standard heated rear seats to keep those passengers extremely comfortable in the winter. Heated rear seats aren't available in the Q3.

Standard air-conditioned seats in the Envision Avenir keep the driver and front passenger comfortable and take the sting out of hot seats in Summer. The Q3 doesn't offer air-conditioned seats.

On extremely cold winter days, the Envision's optional heated steering wheel provides comfort, allowing the driver to steer safely and comfortably before the vehicle heater warms up. The Q3 doesn't offer a heated steering wheel.

The Envision Avenir has standard massaging front seats in order to maximize comfort and eliminate fatigue on long trips. Massaging seats aren't available in the Q3.
