For enhanced safety, the front and rear seat shoulder belts of the Audi S5 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 doesn’t offer pretensioners for the rear seat belts.

To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the S5. But it costs extra on the 8 Series.

When descending a steep, off-road slope, the S5’s standard Hill Descent Control allows you to creep down safely. The 8 Series doesn’t offer Hill Descent Control.

Both the S5 and the 8 Series 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, crash mitigating brakes, post-collision automatic braking systems, daytime running lights, rearview cameras, available lane departure warning systems, blind spot warning systems, around view monitors and rear cross-path warning.

For its top level performance in all IIHS frontal, side, rear impact and roof-crush tests, and its standard front crash prevention system, the Insurance Institute for Highway Safety grants the S5 the rating of “Top Pick” for 2017, a rating granted to only 185 vehicles tested by the IIHS. The 8 Series has not been tested, yet.

For better traction, the S5’s optional tires are larger than the largest tires available on the 8 Series (265/30R20 vs. 245/35R20).

The S5’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 8 Series’ standard 45 series front tires. The S5’s optional tires have a lower 30 series profile than the 8 Series’ optional 35 series front tires.

The S5 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; 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.
