Safety

For enhanced safety, the front shoulder belts of the Chevrolet Tahoe are height-adjustable, and the middle and rear seat shoulder belts have child comfort guides to move the belt to properly fit children. A better fit can prevent injuries and the increased comfort also encourages children to buckle up. The Audi Q7 doesn’t offer comfort guides on its middle or rear seat belts.

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 Tahoe are reminded to check the back seat if they opened the rear door before starting out. The Q7 doesn’t offer a back seat reminder.

The Tahoe has a standard front seat center airbag, which deploys between the driver and front passenger, protecting them from injuries caused by striking each other in serious side impacts. The Q7 doesn’t offer front seat center airbags.

Both the Tahoe and the Q7 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, 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, front parking sensors and rear cross-path warning.

Warranty

Chevrolet’s powertrain warranty covers the Tahoe 1 year and 10,000 miles longer than Audi covers the Q7. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 5 years or 60,000 miles. Coverage on the Q7 ends after only 4 years or 50,000 miles.

There are almost 10 times as many Chevrolet dealers as there are Audi dealers, which makes it much easier should you ever need service under the Tahoe’s warranty.

Reliability

The Tahoe 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 run on only half of its cylinders at a time, reduce its power and light a warning lamp on the dashboard so the driver can get to a service station for repairs. The Q7 doesn’t offer a lost coolant limp home mode, so a coolant leak could strand you or seriously damage the truck’s engine.

To reliably power the ignition and other systems and to recharge the battery, the Tahoe has a standard 150-amp alternator. The Q7’s standard 120-amp alternator isn’t as powerful.

To reliably start during all conditions and help handle large electrical loads, the Tahoe has a standard 720-amp battery. The Q7’s 380-amp battery isn’t as powerful.

J.D. Power and Associates rated the Tahoe third among large SUVs in their 2018 Initial Quality Study. The Q7 isn’t in the top three in its category.

J.D. Power and Associates’ 2018 Initial Quality Study of new car owners surveyed provide the statistics that show that Chevrolet vehicles are better in initial quality than Audi vehicles. J.D. Power ranks Chevrolet 6th in initial quality, above the industry average. With 23 more problems per 100 vehicles, Audi is ranked 25th, below the industry average.

J.D. Power and Associates’ 2018 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Chevrolet vehicles are more reliable than Audi vehicles. J.D. Power ranks Chevrolet 6th in reliability, above the industry average. With 17 more problems per 100 vehicles, Audi is ranked 13th.

Engine

The Tahoe’s standard 5.3 V8 produces 107 more horsepower (355 vs. 248) and 110 lbs.-ft. more torque (383 vs. 273) than the Q7 45 TFSI’s standard 2.0 turbo 4 cyl. The Tahoe’s 5.3 V8 produces 26 more horsepower (355 vs. 329) and 58 lbs.-ft. more torque (383 vs. 325) than the Q7 55 TFSI’s standard 3.0 supercharged V6. The Tahoe’s optional 6.2 V8 produces 91 more horsepower (420 vs. 329) and 135 lbs.-ft. more torque (460 vs. 325) than the Q7 55 TFSI’s standard 3.0 supercharged V6.

Fuel Economy and Range

An engine control system that can shut down half of the engine’s cylinders helps improve the Tahoe’s fuel efficiency. The Q7 doesn’t offer a system that can shut down part of the engine.

The Tahoe has 3.5 gallons more fuel capacity than the Q7 (26 vs. 22.5 gallons), for longer range between fill-ups.

Transmission

A 10-speed automatic is standard on the Chevrolet Tahoe EcoTec3 6.2 V8, for better acceleration and lower engine speed on the highway. Only an eight-speed automatic is available for the Q7.

Tires and Wheels

For better traction, the Tahoe has larger standard tires than the Q7 (265/65R18 vs. 255/55R19).

For better ride, handling and brake cooling the Tahoe offers optional 22-inch wheels. The Q7’s largest wheels are only 21-inches.

The Chevrolet Tahoe’s wheels have 6 lugs for longer wheel bearing life, less chance of rotor warping and greater strength. The Audi Q7 only has 5 wheel lugs per wheel.

The Tahoe 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 Q7 doesn’t offer vehicle monitored tire inflation.

The Tahoe has a standard full size spare tire so a flat doesn’t interrupt your trip. A full size spare isn’t available on the Q7, 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. Some models of the Q7 don’t even offer run-flats.

Suspension and Handling

The Tahoe offers an optional automatic front and rear load leveling suspension to keep ride height level with a heavy load or when towing. The Tahoe’s height leveling suspension allows the driver to raise ride height for better off-road clearance and then lower it again for easier entering and exiting and better on-road handling. The Q7 doesn’t offer a load leveling suspension.

For better handling and stability, the track (width between the wheels) on the Tahoe is 2.6 inches wider in the front and 2.1 inches wider in the rear than on the Q7.

The Tahoe’s front to rear weight distribution is more even (51.6% to 48.4%) than the Q7’s (55% to 45%). This gives the Tahoe more stable handling and braking.

For better maneuverability, the Tahoe’s turning circle is 1.7 feet tighter than the Q7’s (39 feet vs. 40.7 feet).

Chassis

The front grille of the Tahoe uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The Q7 doesn’t offer active grille shutters.

As tested by Car and Driver while at idle, the interior of the Tahoe Premier 4x4 is quieter than the Q7 Prestige (39 vs. 43 dB).

Passenger Space

The Tahoe offers optional seating for 9 passengers; the Q7 can only carry 7.

The Tahoe has 4.4 inches more front headroom, 3.6 inches more front legroom, 5.3 inches more front shoulder room, .2 inches more rear legroom, 6.6 inches more rear shoulder room, 2.2 inches more third row headroom and 13.2 inches more third row shoulder room than the Q7.

Cargo Capacity

The Tahoe’s cargo area provides more volume than the Q7.

Pressing a switch automatically lowers the Tahoe’s (except LS) optional second and third row seats, to make changing between passengers and cargo easier. The Q7 doesn’t offer automatic folding second row seats.

The Tahoe’s rear cargo window opens separately from the rest of the liftgate door to allow quicker loading of small packages. The Q7’s rear cargo window doesn’t open.

Towing

The Tahoe’s minimum standard towing capacity is much higher than the Q7’s (6400 vs. 4400 pounds). Maximum trailer towing in the Audi Q7 is only 7700 pounds. The Tahoe offers up to a 8600 lbs. towing capacity.

Ergonomics

The Tahoe’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 Q7 does not have an oil pressure gauge.

To improve rear visibility by keeping the rear window clear, the Tahoe has a standard rear fixed intermittent wiper with a full on position. The rear wiper standard on the Q7 only has an intermittent setting, so in a hard rain visibility isn’t as good.

Consumer Reports rated the Tahoe’s headlight performance “Very Good,” a higher rating than the Q7’s headlights, which were rated “Good.”

The Tahoe 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 Q7 doesn’t offer a house-current electrical outlet.

Model Availability

The Tahoe is available in both rear-wheel drive and four-wheel drive configurations. The Q7 doesn’t offer a two-wheel drive configuration.

Economic Advantages

The Tahoe will cost the buyer less in the long run because of its superior resale value. The IntelliChoice estimates that the Tahoe will retain 55.17% to 55.7% of its original price after five years, while the Q7 only retains 4.96% to 83.4%.

According to The Car Book by Jack Gillis, the Tahoe is less expensive to operate than the Q7 because typical repairs cost much less on the Tahoe than the Q7, including $64 less for front brake pads, $681 less for a starter, $385 less for fuel injection, $523 less for front struts, $191 less for a timing belt/chain and $122 less for a power steering pump.

IntelliChoice estimates that five-year ownership costs (depreciation, financing, insurance, fuel, fees, repairs and maintenance) for the Chevrolet Tahoe will be $6654 to $11509 less than for the Audi Q7.

Recommendations

J.D. Power and Associates rated the Tahoe first among large SUVs in owner reported satisfaction. This includes how well the vehicle performs and satisfies its owner’s expectations. The Q7 isn’t in the top three.

The Chevrolet Tahoe outsold the Audi Q7 by almost three to one during 2018.
