The E-Class Coupe’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Wraith doesn’t offer pre-crash pretensioners.
For enhanced safety, the front seat shoulder belts of the Mercedes E-Class Coupe are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The Rolls-Royce Wraith doesn’t offer height-adjustable seat belts.
The E-Class Coupe has standard Active Brake Assist, which use forward mounted sensors to warn the driver of a possible collision ahead. If the driver doesn’t react and the system determines a collision is imminent, it automatically applies the brakes at full-force in order to reduce the force of the crash or avoid it altogether. The Wraith doesn't offer collision warning or crash mitigation brakes.
The E-Class Coupe 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 Wraith 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.
The E-Class Coupe offers all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Wraith doesn’t offer all-wheel drive.
The E-Class Coupe’s blind spot warning system uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them. The Wraith doesn’t offer a system to reveal objects in the driver’s blind spots.
To help make backing out of a parking space safer, the E-Class Coupe’s standard rear cross-path warning system uses sensors in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The Wraith doesn’t offer a cross-path warning system.
The E-Class Coupe’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 Wraith doesn’t offer a driver alert monitor.
Both the E-Class Coupe and the Wraith have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, around view monitors, available lane departure warning systems and rear parking sensors.
