For enhanced safety, the front and rear seat shoulder belts of the Mercedes E-Class Coupe have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision. The Infiniti Q60 doesn’t offer pretensioners for the rear seat belts.
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 Infiniti Q60 doesn’t offer height-adjustable seat belts.
The Mercedes E-Class Coupe has a standard driver’s side knee airbag mounted low on the dashboard. The knee airbag helps prevent the driver from sliding under the seatbelts or the main frontal airbag; this keeps the driver better positioned during a collision for maximum protection. A knee airbag also helps keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The Q60 doesn’t offer knee airbags.
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 Q60 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 has a standard blind spot warning system which uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them. Only the Q60 Luxe/Red Sport 400 offers a blind spot warning system.
To help make backing out of a parking space safer, the E-Class Coupe has a standard rear cross-path warning system, which uses sensors in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. Only the Q60 Luxe/Red Sport 400 has a rear 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 Q60 doesn’t offer a driver alert monitor.
Both the E-Class Coupe and the Q60 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, collision warning systems, daytime running lights, rearview cameras, available all wheel drive, lane departure warning systems and rear parking sensors.
