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 Rolls-Royce Spectre doesn’t offer height-adjustable seat belts.
The Taycan has standard multi-collision braking, which automatically apply the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Spectre 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 Taycan has a standard Maneuvering Assist that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The Spectre doesn’t offer backup collision prevention brakes.
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 Spectre doesn’t offer a night vision system.
Both the Taycan and Spectre have rear cross-traffic warning, but the Taycan has Rear Cross Traffic Alert (automatically applies the brakes) to better prevent a collision when backing near traffic. The Spectre’s Cross Traffic Warning doesn’t automatically brake.
Both the Taycan and the Spectre have standard driver and passenger frontal airbags, 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, rear cross-path warning, driver alert monitors and available around view monitors.
