The BMW 2 Series Gran Coupe has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags helps prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The C-Class Sedan doesn’t offer a front passenger side knee airbag.
The 2 Series Gran Coupe’s 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. The C-Class Sedan doesn’t offer a lane departure warning system.
To help make backing out of a parking space safer, the 2 Series Gran Coupe has standard Cross Traffic Warning, helping the driver avoid collisions. Mercedes charges extra for Rear Cross-Traffic Alert on the C-Class Sedan.
Both the 2 Series Gran Coupe and the C-Class Sedan have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, post-collision automatic braking systems, daytime running lights, blind spot warning systems, rearview cameras, driver alert monitors and available all wheel drive.
