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 Supra doesn’t offer pre-crash pretensioners.
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 Supra doesn’t offer front seat center airbags.
The CLE has a standard Post Collision Brake, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Supra 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 CLE offers four-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Supra doesn’t offer four-wheel drive.
Earlier warning of stopped traffic, traffic signals, dangerous road conditions, weather, or accidents, can keep driver's safer and prevent crashes. The CLE has Car-to-X Communication, a system that seamlessly communicates important warnings to the driver about impending danger, if they're available. The Supra doesn’t offer a system that can receive automated systems from infrastructure or other vehicles.
The CLE offers an optional Surround View System to allow the driver to see objects all around the vehicle on a screen. The Supra only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.
The CLE has a standard blind spot warning system that uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them. A system to reveal vehicles in the Supra’s blind spot costs extra.
To help make backing out of a parking space safer, the CLE has standard Rear Cross-Traffic Alert and Active Brake Assist automatically engages the brakes to help avoid a collision. Toyota charges extra for Rear Cross Traffic Alert on the Supra.
Both the CLE and the Supra 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, daytime running lights, rearview cameras, driver alert monitors and available lane departure warning systems.
The Mercedes CLE weighs 657 to 1305 pounds more than the Toyota Supra. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.
