In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the AMG CLE are reminded to check the back seat. The M4 doesn’t offer a back seat reminder.
The AMG CLE has a standard front seat center airbag, which deploys between the driver and front passenger, protecting them from injuries caused by striking each other in serious side impacts. The M4 doesn’t offer front seat center airbags.
To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the AMG CLE. But it costs extra on the M4.
Earlier warning of stopped traffic, traffic signals, dangerous road conditions, weather, or accidents, can keep driver's safer and prevent crashes. The AMG CLE has Car-to-X Communication, a system that seamlessly communicates important warnings to the driver about impending danger, if they're available. The M4 doesn’t offer a system that can receive automated systems from infrastructure or other vehicles.
Both the AMG CLE and M4 have rear cross-traffic warning, but the AMG CLE has Active Brake Assist (automatically applies the brakes) to better prevent a collision when backing near traffic. The M4’s Cross Traffic Warning doesn’t automatically brake.
Both the AMG CLE and the M4 have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, post-collision automatic braking systems, daytime running lights, blind spot warning systems, rearview cameras, rear cross-path warning, driver alert monitors and available lane departure warning systems.
