The S5’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Charger doesn’t offer pre-crash pretensioners.
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 Charger 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 Charger have rear cross-traffic warning, but the S5 Premium Plus/Prestige has Automatic Brake Activation (automatically applies the brakes) to better prevent a collision when backing near traffic. The Charger’s Rear Cross Path Detection doesn’t automatically brake.
Both the S5 and the Charger have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, four-wheel antilock brakes, all-wheel drive, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, rearview cameras, available blind spot warning systems and around view monitors.
