For enhanced safety, the front and rear seat shoulder belts of the Mercedes E-Class Sedan 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 Cadillac CT5 doesn’t offer pretensioners for its rear seat belts.
The E-Class Sedan’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The CT5 doesn’t offer pre-crash pretensioners.
The E-Class Sedan offers an optional Post Collision Brake, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The CT5 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 E-Class Sedan. But it costs extra on the CT5.
Earlier warning of stopped traffic, traffic signals, dangerous road conditions, weather, or accidents, can keep driver's safer and prevent crashes. The E-Class Sedan has Car-to-X Communication, a system that seamlessly communicates important warnings to the driver about impending danger, if they're available. The CT5 doesn’t offer a system that can receive automated systems from infrastructure or other vehicles.
Both the E-Class Sedan and CT5 have rear cross-traffic warning, but the E-Class Sedan has Active Brake Assist (automatically applies the brakes) to better prevent a collision when backing near traffic. The CT5’s Rear Cross Traffic Alert doesn’t automatically brake.
The E-Class Sedan’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The CT5 doesn’t offer a driver alert monitor.
Both the E-Class Sedan and the CT5 have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, blind spot warning systems, rearview cameras, rear cross-path warning and available lane departure warning systems.
