For enhanced safety, the front and rear seat shoulder belts of the Audi A6 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 8 Series Gran Coupe doesn’t offer pretensioners for the rear seat belts.

For enhanced safety, the front seat shoulder belts of the Audi A6 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 8 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 A6. But it costs extra on the 8 Series Gran Coupe.

Both the A6 and the 8 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, crash mitigating brakes, post-collision automatic braking systems, daytime running lights, rearview cameras, available night vision systems, blind spot warning systems, around view monitors and rear cross-path warning.

For its top level performance in IIHS driver and passenger-side small overlap frontal, moderate overlap frontal, side impact, roof strength and head restraint tests, its standard front crash prevention system, and its headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the A6 its highest rating: “Top Pick Plus” for 2019, a rating granted to only 55 vehicles tested by the IIHS. The 8 Series Gran Coupe has not been tested, yet.

For better traction, the A6’s optional tires are larger than the largest tires available on the 8 Series Gran Coupe (255/40R20 vs. 245/45R18).

For better ride, handling and brake cooling the A6 has standard 19-inch wheels. Smaller 18-inch wheels are standard on the 840i Gran Coupe. The A6 Prestige’s optional 21-inch wheels are larger than the 20-inch wheels optional on the 8 Series Gran Coupe.

The A6 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 8 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.

The A6’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 8 Series Gran Coupe does not have an oil pressure gauge.
