Safety Comparison

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 and rear 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.

The A7 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 6 Series Gran Coupe 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.

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.

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, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available crash mitigating brakes, night vision systems and lane departure warning systems.

Reliability Comparison

To reliably power the ignition and other systems and to recharge the battery, the A7 has a 190-amp alternator. The 6 Series Gran Coupe’s standard 170-amp alternator isn’t as powerful.

J.D. Power and Associates’ 2015 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Audi vehicles are more reliable than BMW vehicles. J.D. Power ranks Audi 14th in reliability, above the industry average. With 8 more problems per 100 vehicles, BMW is ranked 18th.

Engine Comparison

The A7’s 3.0 supercharged V6 produces 18 more horsepower (333 vs. 315) than the 640i Gran Coupe’s standard 3.0 turbo 6 cyl.

The A7’s 3.0 turbo V6 diesel produces 98 lbs.-ft. more torque (428 vs. 330) than the 640i Gran Coupe’s standard 3.0 turbo 6 cyl.

Fuel Economy and Range Comparison

On the EPA test cycle the A7 TDI gets better fuel mileage than the 640i Gran Coupe xDrive (25 city/38 hwy vs. 20 city/29 hwy).

On the EPA test cycle the A7 3.0T gets better fuel mileage than the 640i Gran Coupe xDrive (20 city/30 hwy vs. 20 city/29 hwy).

Tires and Wheels Comparison

For better traction, the A7 has larger standard tires than the 6 Series Gran Coupe (255/40R19 vs. 245/45R18).

The A7’s standard tires provide better handling because they have a lower 40 series profile (height to width ratio) that provides a stiffer sidewall than the 640i Gran Coupe’s standard 45 series tires.

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.

Suspension and Handling Comparison

For better handling and stability, the track (width between the wheels) on the A7 is 1.2 inches wider in the front than the average track on the 6 Series Gran Coupe.

The A7 handles at .96 G’s, while the 650i Gran Coupe pulls only .92 G’s of cornering force in a Motor Trend skidpad test.

For better maneuverability, the A7’s turning circle is .2 feet tighter than the 6 Series Gran Coupe’s (39 feet vs. 39.2 feet). The A7’s turning circle is 2 feet tighter than the M6 Gran Coupe’s (39 feet vs. 41 feet).

Chassis Comparison

The design of the Audi A7 amounts to more than styling. The A7 offers aerodynamic coefficients of drag from .28 to .29 Cd (depending on bodystyle and options). That is lower than the 6 Series Gran Coupe (.3 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 Comparison

Because it has more passenger and cargo room, the A7 is rated a Large car by the EPA, while the 6 Series Gran Coupe is rated a Compact.

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

Cargo Capacity Comparison

The A7 has a much larger trunk than the 6 Series Gran Coupe with its rear seat up (24.5 vs. 12 cubic feet).

To make loading and unloading groceries and cargo easier when your hands are full, the A7’s trunk can be opened just by waving your foot, leaving your hands completely free. The A7 also has a standard power trunk, which opens and closes automatically by pressing a button. The 6 Series Gran Coupe doesn’t offer a power or hands-free opening trunk.

Ergonomics Comparison

Heated windshield washer nozzles are standard on the A7 to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The 6 Series Gran Coupe doesn’t offer heated windshield washer nozzles.

Economic Advantages Comparison

The A7 will cost the buyer less in the long run because of its superior resale value. Kiplinger’s estimates that the A7 will retain a greater percentage of its original price after three and five years than the 6 Series Gran Coupe.
