The Chiron has a standard 360 degree parking monitor to allow the driver to see objects all around the vehicle on a screen. The Aventador only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.
The Chiron’s blind spot camera is used to display a wide-angle view of the passenger side of the road. The Aventador doesn’t offer a system to reveal objects in the driver’s blind spots.
Both the Chiron and the Aventador have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, four-wheel antilock brakes, all wheel drive, traction control, electronic stability systems to prevent skidding, daytime running lights and rearview cameras.
The Bugatti Chiron weighs 615 to 1036 pounds more than the Lamborghini Aventador. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.
