Tesla Cybertruck - How High Can It Go? Why is air suspension usually available on luxury vehicles? Other than comfort, one of the main reasons is to allow the driver and passengers to easily enter and exit the car! For a utility vehicle like the Cybertruck, it needs to be high if it's going off-roading. Using air suspension allows the vehicle to have more ground clearance while still providing easy access for the driver and passengers. The Cybertruck is durable and rugged enough to go anywhere.
