For enhanced safety, the front and rear seat shoulder belts of the Porsche Taycan have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision. The BMW 7 Series doesn’t offer pretensioners for its rear seat belts.
For enhanced safety, the front seat shoulder belts of the Porsche Taycan 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 7 Series doesn’t offer height-adjustable seat belts.
A passive infrared night vision system optional on the Taycan helps the driver to more easily detect people, animals or other objects in front of the vehicle at night. Using an infrared camera to detect heat, the system then displays the image on a monitor in the dashboard. The 7 Series doesn’t offer a night vision system.
Both the Taycan and the 7 Series 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, lane departure warning systems, rearview cameras, available blind spot warning systems and around view monitors.
