For enhanced safety, the front and rear seat shoulder belts of the Audi A7 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 BMW 6 Series Gran Coupe doesn’t offer pretensioners for the rear seat belts.

For enhanced safety, the front seat shoulder belts of the Audi A7 are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The BMW 6 Series Gran Coupe doesn’t offer height-adjustable seat belts.

Both the A7 and 6 Series Gran Coupe have child safety locks to prevent children from opening the rear doors. The A7 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 6 Series Gran Coupe’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 provide maximum traction and stability on all roads, All-Wheel Drive is standard on the A7. But it costs extra on the 6 Series Gran Coupe.

To help make backing safer, the A7’s optional 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 6 Series Gran Coupe doesn’t offer a cross-path warning system.

Both the A7 and the 6 Series Gran Coupe have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, post-collision automatic braking systems, daytime running lights, rearview cameras, available night vision systems, lane departure warning systems, blind spot warning systems and around view monitors.


From surveys of all its subscribers, Consumer Reports’ December 2018 Auto Issue reports that Audi vehicles are more reliable than BMW vehicles. Consumer Reports ranks Audi 1 place higher in reliability than BMW.


The A7’s 3.0 turbo V6 hybrid produces 20 more horsepower (335 vs. 315) and 37 lbs.-ft. more torque (369 vs. 332) than the 640i Gran Coupe’s standard 3.0 turbo 6 cyl.

Fuel Economy and Range

On the EPA test cycle the A7 gets better fuel mileage than the 640i xDrive Gran Coupe (22 city/29 hwy vs. 19 city/28 hwy).

To lower fuel costs and make buying fuel easier, the Audi A7 uses regular unleaded gasoline (premium recommended for maximum performance). The 6 Series Gran Coupe requires premium, which can cost 20 to 55 cents more per gallon.

The A7 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 6 Series Gran Coupe doesn’t offer a cap-less fueling system.

Environmental Friendliness

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Audi A7 higher (5 out of 10) than the BMW 6 Series Gran Coupe (1 to 3). This means the A7 produces up to 39 pounds less smog-producing pollutants than the 6 Series Gran Coupe every 15,000 miles.


The A7’s launch control uses engine electronics to hold engine RPM’s precisely in order to provide the most stable and rapid acceleration possible, using all of the available traction. The 6 Series Gran Coupe doesn’t offer launch control.

The A7 stops shorter than the 6 Series Gran Coupe:

Tires and Wheels

For better ride, handling and brake cooling the A7 has standard 19-inch wheels. Smaller 18-inch wheels are standard on the 640i Gran Coupe. The A7 Prestige’s optional 21-inch wheels are larger than the 20-inch wheels optional on the 6 Series Gran Coupe.

The A7 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 6 Series Gran Coupe; 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 6 Series Gran Coupe don’t even offer run-flats.

Suspension and Handling

For better handling and stability, the track (width between the wheels) on the A7 is 1.5 inches wider in the front than the average track on the 6 Series Gran Coupe.

The A7 Prestige handles at .90 G’s, while the 640i Gran Coupe pulls only .89 G’s of cornering force in a Car and Driver skidpad test.

For better maneuverability, the A7’s turning circle is 2.8 feet tighter than the 6 Series Gran Coupe’s (36.4 feet vs. 39.2 feet). The A7’s turning circle is 4.6 feet tighter than the M6 Gran Coupe’s (36.4 feet vs. 41 feet).


The design of the Audi A7 amounts to more than styling. The A7 has an aerodynamic coefficient of drag of .28 Cd. That is lower than the 6 Series Gran Coupe (.29 to .33) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the A7 get better fuel mileage.

As tested by Car and Driver while under full throttle, the interior of the A7 Prestige is quieter than the 640i Gran Coupe (73 vs. 75 dB).

Passenger Space

Because it has more passenger and cargo room, the EPA rates the A7 a Mid-size car, while the 6 Series Gran Coupe is rated a Compact.

The A7 has .5 inches more front shoulder room, .1 inches more rear headroom, 1.7 inches more rear legroom and 1.3 inches more rear shoulder room than the 6 Series Gran Coupe.

For enhanced passenger comfort on long trips the A7’s rear seats recline. The 6 Series Gran Coupe’s rear seats don’t recline.

Cargo Capacity

The A7 has a much larger trunk than the 6 Series Gran Coupe with its rear seat up (24.9 vs. 12 cubic feet).

To make loading and unloading groceries and cargo easier when your hands are full, the A7’s power liftgate can be opened or closed just by kicking your foot under the back bumper, leaving your hands completely free. The 6 Series Gran Coupe doesn’t offer a power or hands-free opening trunk.


The A7 has a 3500 lbs. towing capacity. The 6 Series Gran Coupe has no towing capacity.

Servicing Ease

J.D. Power and Associates surveys of service recipients show that Audi service is better than BMW. J.D. Power ranks Audi third in service department satisfaction. With a 14% lower rating, BMW is ranked 8th.


To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the A7 has standard extendable sun visors. The 6 Series Gran Coupe doesn’t offer extendable visors.


The Audi A7/S7/RS 7 outsold the BMW 6 Series by 43% during 2017.
