Safety

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. 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.

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, side-impact head airbags, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, post-collision automatic braking systems, rearview cameras, available night vision systems, lane departure warning systems, blind spot warning systems and around view monitors.

Reliability

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.

Engine

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 Gran Coupe xDrive (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.

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.

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.

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).

Chassis

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.

Passenger Space

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.

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, just kicking your foot under the back bumper can open the A7’s power liftgate, leaving your hands completely free. The A7’s power liftgate can also be opened or closed by pressing a button. The 6 Series Gran Coupe doesn’t offer a power or hands-free opening trunk.

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.

Ergonomics

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.

Recommendations

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