The 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 4 Series Convertible doesn’t offer front seat center airbags.
To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the CLE. But it costs extra on the 4 Series Convertible.
Earlier warning of stopped traffic, traffic signals, dangerous road conditions, weather, or accidents, can keep driver's safer and prevent crashes.

The 4 Series Convertible doesn’t offer a system that can receive automated systems from infrastructure or other vehicles.
Both the CLE and 4 Series Convertible have rear cross-traffic warning, but the CLE has Active Brake Assist (automatically applies the brakes) to better prevent a collision when backing near traffic. The 4 Series Convertible’s Cross Traffic Warning doesn’t automatically brake.
