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 Honda Clarity Fuel Cell doesn’t offer pretensioners for the rear seat belts.
The Taycan’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Clarity Fuel Cell doesn’t offer pre-crash pretensioners.
Both the Taycan and Clarity Fuel Cell have child safety locks to prevent children from opening the rear doors. The Taycan has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The Clarity Fuel Cell’s child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.
The Porsche Taycan 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 Clarity Fuel Cell doesn’t offer a front passenger side knee airbag.
The Taycan offers all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Clarity Fuel Cell doesn’t offer all-wheel drive.
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 Clarity Fuel Cell doesn’t offer a night vision system.
The Taycan offers an optional Surround View System to allow the driver to see objects all around the vehicle on a screen. The Clarity Fuel Cell only offers a rear monitor.
To help make backing out of a parking space safer, the Taycan’s optional rear cross-path warning system uses sensors in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The Clarity Fuel Cell doesn’t offer a cross-path warning system.
Both the Taycan and the Clarity Fuel Cell have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, rearview cameras and available blind spot warning systems.
The Porsche Taycan weighs 434 to 1065 pounds more than the Honda Clarity Fuel Cell. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.
