For enhanced safety, the front and middle seat shoulder belts of the Audi Q7 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 Chevrolet Tahoe doesn’t offer pretensioners for the middle seat belts.

The Q7’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Tahoe doesn’t offer pre-crash pretensioners.

The Q7 has a standard Secondary Collision Brake Assist, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Tahoe doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.

Over 200 people are killed each year when backed over by motor vehicles. The Q7 offers an optional backup collision prevention system that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The Tahoe doesn’t offer backup collision prevention brakes.

To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the Q7. But it costs extra on the Tahoe.

A passive infrared night vision system optional on the Q7 Prestige helps the driver to more easily detect people, animals or other objects in front of the vehicle at night. Using an infrared camera to detect heat, the system then displays the image on a monitor in the dashboard. The Tahoe doesn’t offer a night vision system.

The Q7 Premium Plus/Prestige has a standard Top View Cameras to allow the driver to see objects all around the vehicle on a screen. The Tahoe only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.

For better protection of the passenger compartment, the Q7 uses safety cell construction with a three-dimensional high-strength frame that surrounds the passenger compartment. It provides extra impact protection and a sturdy mounting location for door hardware and side impact beams. The Tahoe uses a body-on-frame design, which has no frame members above the floor of the vehicle.

Both the Q7 and the Tahoe have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available blind spot warning systems and rear cross-path warning.

On the EPA test cycle the Q7 55 TFSI gets better fuel mileage than the Tahoe 4WD (17 city/21 hwy vs. 15 city/21 hwy).

On the EPA test cycle the Q7 45 TFSI gets better fuel mileage than the Tahoe 4x4 with its standard engine (19 city/25 hwy vs. 15 city/21 hwy).

Regenerative brakes improve the Q7 55 TFSI’s fuel efficiency by converting inertia back into energy instead of wasting it. The Tahoe doesn’t offer a regenerative braking system.

In heavy traffic or at stoplights the Q7’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. (Start/Stop isn’t accounted in present EPA fuel mileage tests.) The Tahoe doesn’t offer an automatic engine start/stop system.

The Q7’s standard tires provide better handling because they have a lower 55 series profile (height to width ratio) that provides a stiffer sidewall than the Tahoe LS/LT’s standard 65 series tires. The Q7 Prestige’s optional tires have a lower 35 series profile than the Tahoe’s optional 45 series tires.

For better ride, handling and brake cooling the Q7 has standard 19-inch wheels. Smaller 18-inch wheels are standard on the Tahoe LS/LT.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires available on the Q7 can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The Tahoe doesn’t offer run-flat tires.

Suspension and Handling

For superior ride and handling, the Audi Q7 has fully independent front and rear suspensions. An independent suspension allows the wheels to follow the road at the best angle for gripping the pavement, without compromising ride comfort. The Chevrolet Tahoe has a solid rear axle, with a non-independent rear suspension.

The Q7 has standard front and rear stabilizer bars, which help keep the Q7 flat and controlled during cornering. The Tahoe’s suspension doesn’t offer a rear stabilizer bar.

For a smoother ride and more stable handling, the Q7’s wheelbase is 1.9 inches longer than on the Tahoe (117.9 inches vs. 116 inches).

The Q7 Prestige handles at .86 G’s, while the Tahoe Premier 4x4 pulls only .76 G’s of cornering force in a Car and Driver skidpad test.

The Q7 Premium Plus executes Motor Trend’s “Figure Eight” maneuver 1.9 seconds quicker than the Tahoe Premier 4x4 (26.4 seconds @ .68 average G’s vs. 28.3 seconds @ .62 average G’s).

For greater off-road capability the Q7 has a greater minimum ground clearance than the Tahoe (8.3 vs. 7.9 inches), allowing the Q7 to travel over rougher terrain without being stopped or damaged. The Q7 w/Air Suspension’s minimum ground clearance is 1.8 inches higher than on the Tahoe (9.7 vs. 7.9 inches).

The Audi Q7 may be more efficient, handle and accelerate better because it weighs about 500 to 550 pounds less than the Chevrolet Tahoe.

The Q7 is 4.7 inches shorter than the Tahoe, making the Q7 easier to handle, maneuver and park in tight spaces.

Unibody construction lowers the Q7’s center of gravity significantly without reducing ground clearance. This contributes to better on the road handling and better off-road performance and stability. In addition, unibody construction makes the chassis stiffer, improving handling and reducing squeaks and rattles. The Tahoe uses body-on-frame design instead.

Unlike the driver-only memory system in the Tahoe LT/Premier, the Q7 Prestige offers an optional passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, steering wheel position and outside mirror angle and the front passenger seat also adjusts to the new passenger’s preset preferences.

The Q7’s power parking brake sets with one touch and releases with one touch or automatically. The Tahoe’s parking brake has to released manually.

The Q7’s front and rear power windows all open or close fully with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside the car. The Tahoe’s rear power window switches have to be held the entire time to open or close them fully.

If the windows are left open on the Q7 the driver can close them all at the outside door handle or from a distance using the remote. On a hot day the driver can lower the windows from a distance using the keyless remote. The driver of the Tahoe can only operate the windows from inside the vehicle, with the ignition on.

The Q7 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 Tahoe doesn’t offer a locking fuel door.

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The Q7 Prestige has standard headlight washers to keep headlight output high. The Tahoe doesn’t offer headlight washers.

A manual rear sunshade and rear side window sunshades are optional in the Q7 (except Premium) to help block heat and glare for the rear passengers. The Tahoe doesn’t offer a rear sunshade.

The Q7 Prestige offers optional massaging front seats in order to maximize comfort and eliminate fatigue on long trips. Massaging seats aren’t available in the Tahoe.
