To maximize occupant safety, the front and rear seat shoulder belts of the Mercedes C-Class Coupe have pretensioners to eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Toyota Supra doesn’t offer pretensioners.
The C-Class Coupe’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 C-Class Coupe has standard whiplash protection, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the whiplash protection system moves the headrests forward to prevent neck and spine injuries. The Supra doesn’t offer a whiplash protection system.
The C-Class Coupe offers all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Supra doesn’t offer all-wheel drive.
The C-Class Coupe 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 C-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. A system to reveal vehicles in the Supra’s blind spot costs extra.
Both the C-Class Coupe and the Supra have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger 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, available lane departure warning systems and rear cross-path warning.
