The CLE’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The 2 Series doesn’t offer pre-crash pretensioners.
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 CLE are reminded to check the back seat. The 2 Series doesn’t offer a back seat reminder.
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 2 Series doesn’t offer front seat center airbags.
To allow off-road and deep snow capability, Four-Wheel Drive is standard on the CLE. But it costs extra on the 2 Series.
Both the CLE and 2 Series 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 2 Series’ Cross Traffic Warning doesn’t automatically brake.
Both the CLE and the 2 Series 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, available lane departure warning systems and around view monitors.
