The S5 Sportback 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 CLS 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.

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

Both the S5 Sportback and the AMG CLS have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, height adjustable front shoulder belts, 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 Sportback the rating of “Top Pick” for 2017, a rating granted to only 185 vehicles tested by the IIHS. The AMG CLS has not been tested, yet.
