The 2 Series Gran Coupe has a standard PostCrash iBrake, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The A-Class 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.
Over 200 people are killed each year when backed over by motor vehicles. The 2 Series Gran Coupe offers optional Active Park Distance Control that use rear sensors to monitor for objects to the rear and automatically apply the brakes to prevent a collision. The A-Class doesn’t offer backup collision prevention brakes.
The 2 Series Gran Coupe’s standard lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane and gently nudges the vehicle back towards its lane. A lane departure warning system costs extra on the A-Class.
To help make backing out of a parking space safer, the 2 Series Gran Coupe’s standard Cross Traffic Warning uses sensors in the rear to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The A-Class doesn’t offer a rear cross-path warning system.
Both the 2 Series Gran Coupe and the A-Class have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front seatbelt pretensioners, front wheel drive, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, blind spot warning systems, rearview cameras, driver alert monitors and available all wheel drive.
For its top level performance in IIHS driver and passenger-side small overlap frontal, moderate overlap frontal, side impact, roof strength and head restraint tests, its standard vehicle-to-vehicle front crash prevention system, its standard vehicle-to-pedestrian front crash prevention system, and its available headlight’s “Acceptable” rating, the Insurance Institute for Highway Safety grants the 2 Series Gran Coupe the rating of “Top Safety Pick” for 2022, a rating granted to only 174 vehicles tested by the IIHS. The A-Class has not been tested, yet.
