For enhanced safety, the front and rear seat shoulder belts of the Nissan Sentra 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 BMW 2 Series Gran Coupe doesn’t offer pretensioners for its rear seat belts.
For enhanced safety, the front seat shoulder belts of the Nissan Sentra are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The BMW 2 Series Gran Coupe doesn’t offer height-adjustable seat belts.
To help make backing out of a parking space safer, the Sentra has standard Rear Cross Traffic Alert, helping the driver avoid collisions. BMW charges extra for Cross Traffic Warning on the 2 Series Gran Coupe.
Both the Sentra and the 2 Series Gran Coupe have standard driver and passenger frontal airbags, front and rear 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, lane departure warning systems, blind spot warning systems, rearview cameras, driver alert monitors, available daytime running lights and around view monitors.
