The A5’s standard pretensioning seatbelts also sense rear collisions and remove slack from the seatbelts to help protect the occupants from whiplash and other injuries. The C-Class Coupe doesn’t offer a whiplash protection system.

The A5 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 C-Class 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 A5. But it costs extra on the C-Class Coupe.

When descending a steep, off-road slope, the A5 Automatic’s standard Hill Descent Control allows you to creep down safely. The C-Class Coupe doesn’t offer Hill Descent Control.

Both the A5 and the C-Class Coupe have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front and rear seatbelt pretensioners, plastic fuel tanks, four-wheel antilock brakes, 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 A5 the rating of “Top Pick” for 2017, a rating granted to only 184 vehicles tested by the IIHS. The C-Class Coupe has not been tested, yet.

Heated windshield washer nozzles are standard on the A5 to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The C-Class Coupe doesn’t offer heated windshield washer nozzles.

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The A5 Prestige has standard headlight washers to keep headlight output high. The C-Class Coupe doesn’t offer headlight washers.
