The S5 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 AMG E-Class Cabriolet 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.

Both the S5 and the AMG E-Class Cabriolet have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front and rear seatbelt pretensioners, four-wheel antilock brakes, all-wheel drive, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, 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 AMG E-Class Cabriolet has not been tested, yet.

Regenerative brakes improve the S5’s fuel efficiency by converting inertia back into energy instead of wasting it. The AMG E-Class Cabriolet doesn’t offer a regenerative braking system.

To lower fuel costs and make buying fuel easier, the Audi S5 uses regular unleaded gasoline (premium recommended for maximum performance). The AMG E-Class Cabriolet requires premium, which can cost 20 to 55 cents more per gallon.

For better traction, the S5’s optional tires are larger than the largest tires available on the AMG E-Class Cabriolet (265/30R20 vs. 245/40R19).

The S5’s optional tires provide better handling because they have a lower 30 series profile (height to width ratio) that provides a stiffer sidewall than the AMG E-Class Cabriolet’s 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 AMG E-Class Cabriolet; 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. Some tire options on the AMG E-Class Cabriolet don’t have a run-flat feature, either.

The Audi S5 may be more efficient, handle and accelerate better because it weighs about 400 to 700 pounds less than the Mercedes AMG E-Class Cabriolet.

The S5 is 5.7 inches shorter than the AMG E-Class Cabriolet, making the S5 easier to handle, maneuver and park in tight spaces.

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The S5 Prestige has standard headlight washers to keep headlight output high. The AMG E-Class Cabriolet doesn’t offer headlight washers.

The S5 will cost the buyer less in the long run because of its superior resale value. The IntelliChoice estimates that the S5 will retain 41.89% to 46.48% of its original price after five years, while the AMG E-Class Cabriolet only retains 39.53%.

IntelliChoice estimates that five-year ownership costs (depreciation, financing, insurance, fuel, fees, repairs and maintenance) for the Audi S5 will be $14501 to $27944 less than for the Mercedes AMG E-Class Cabriolet.
