Safety

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 5 Series Sedan 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 5 Series Sedan doesn’t offer height-adjustable seat belts.

Both the A6 and 5 Series Sedan have child safety locks to prevent children from opening the rear doors. The A6 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 5 Series Sedan’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 A6. But it costs extra on the 5 Series Sedan.

Both the A6 and the 5 Series Sedan 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, crash mitigating brakes, post-collision automatic braking systems, daytime running lights, rearview cameras, available night vision systems, lane departure warning systems, blind spot warning systems, around view monitors and rear cross-path warning.

Fuel Economy and Range

Tires and Wheels

Suspension and Handling

The A6 Prestige handles at .93 G’s, while the 530i pulls only .86 G’s of cornering force in a Motor Trend skidpad test.

The A6 Prestige executes Motor Trend’s “Figure Eight” maneuver 1.4 seconds quicker than the 530i (24.9 seconds @ .75 average G’s vs. 26.3 seconds @ .68 average G’s).

For better maneuverability, the A6’s turning circle is 3.1 feet tighter than the 5 Series Sedan’s (36.4 feet vs. 39.5 feet). The A6’s turning circle is 3.7 feet tighter than the 5 Series Sedan xDrive’s (36.4 feet vs. 40.1 feet).

Servicing Ease

Ergonomics

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The A6 Premium Plus/Prestige has standard headlight washers to keep headlight output high. The 5 Series Sedan doesn’t offer headlight washers.

To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the A6 has standard extendable sun visors. The 5 Series Sedan doesn’t offer extendable visors.
