To maximize occupant safety, the front and rear seat shoulder belts of the Mercedes AMG 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 AMG 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.
Using vehicle speed sensors, smart airbags in the AMG C-Class Coupe deploy with different levels of force or don’t deploy at all to help better protect passengers of all sizes in different collisions. The AMG C-Class Coupe’s side airbags will shut off if a child is leaning against the door. The Supra’s side airbags don’t have smart features and will always deploy full force.
The AMG C-Class Coupe has all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Supra doesn’t offer all-wheel drive.
The AMG 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 AMG 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 AMG 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.
The Mercedes AMG C-Class Coupe weighs 513 to 732 pounds more than the Toyota Supra. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.
