For enhanced safety, the front and rear seat shoulder belts of the Mercedes A-Class have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Honda Accord doesn’t offer pretensioners for the rear seat belts.
The A-Class’ optional pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Accord doesn’t offer pre-crash pretensioners.
The A-Class offers all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Accord doesn’t offer all-wheel drive.
The A-Class offers an optional Surround View System to allow the driver to see objects all around the vehicle on a screen. The Accord 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 A-Class 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. Only the Accord Sport 2.0T/EX/EX-L/Touring offers a blind spot warning system.
Both the A-Class and the Accord have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front wheel drive, 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.
