The Flying Spur has standard whiplash protection, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the whiplash protection system moves the headrests forward to prevent neck and spine injuries. The Panamera doesn’t offer a whiplash protection system.
To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the Flying Spur. But it costs extra on the Panamera.
Both the Flying Spur and the Panamera have standard driver and passenger frontal airbags, front and rear side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, post-collision automatic braking systems, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning and available night vision systems.
The Bentley Flying Spur weighs 522 to 1538 pounds more than the Porsche Panamera. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.
