Tesla Model S Air Suspension In Action, Up Close Look At Underbody With Battery Protecting Shields – Video

3 years ago by Mike Anthony 5

YouTuber, Amund7 gives us a close look at the Model S’ air suspension in action as well as a look at the titanium underbody shields.

Very sleek! One of many reasons why the Model S has a very low drag coefficient.

Very sleek! One of many reasons why the Model S has a very low drag coefficient.

The Smart Air Suspension is an available option on the Model S, which replaces the standard strut suspension and currently costs $2,250, This option also requires the Tech Package ($3,750)

The air suspension allows the driver to raise and lower the vehicle manually via 17″ touchscreen display and depending on the set speed, will automatically lower the Model S for improved aerodynamics. It also levels and adjusts stiffness accordingly to performance, road surface, and cargo.

The Titanium Underbody Shield was recently added as standard back in March 2014 and was later added to the Model S EVs already on the road from that point in time on, at no cost.

As you likely already know, the Model S battery pack lays at the bottom of the vehicle and the titanium underbody shields were an upgrade to even further reduce the chance of battery pack damage. There is also a 6mm armor plating for the battery pack that has been there since the Model S was released in 2012.

To Model S owners with air suspension, are you enjoying your air suspension? Are there any drawbacks?

    Great idea!

    I used to love the old Citroen hydrodynamic suspension, although the ride did not agree with some.

    No doubt that has substantially improved since the stone age though.

    One of my favourite cars was the Citroen SM, which had a Maserati engine in a Citroen body.
    They drank lots of petrol, and rusted like crazy, so there are few examples on the road, and they are now worth a fortune!

    What a car!

    And in my view air suspension is in many ways inherently superior to springs etc, although no doubt many will have far more insight on that than I.

  2. What part of the battery shield is the new titanium piece? Is it the initial leading edge piece which appears to be about 6″ wide?

      From the associated TM blog post on the topic. The original post is here (and the videos of the shield in action are pretty entertaining): http://www.teslamotors.com/blog/tesla-adds-titanium-underbody-shield-and-aluminum-deflector-plates-model-s

      O

      “The first of the three shields is a rounded, hollow aluminum bar that is designed to either deflect objects entirely or, in the case of a self-stabilizing, ultra high strength object, like a three ball steel tow hitch, absorb the impact and force it to pike upwards well forward of the battery pack. This pierces the plastic aeroshield and front trunk liner, but causes no damage affecting safety and the car remains in control and driveable before, during and after the impact.

      This is followed by a titanium plate, which has exceptional strength-to-weight properties and is more commonly seen in aerospace or military applications. The titanium plate prevents sensitive front underbody components from being damaged and aids in neutralizing the road debris.

      By this point, the vast majority of objects will have been deflected or crushed. For the rare piece of debris that remains intact, we added a third shield, which is a shallow angle, solid aluminum extrusion that further absorbs impact energy, provides another layer of deflection and finally causes the Model S to ramp up and over the object if it is essentially incompressible and immovable.”

    In fact i would love to have the bose magnetic suspension system. That one is able to lift the wheel in front of a poth hole. It also recuperates energy normaly lost.

      so how much energy could a coil mounted to suspension components return vs. their weight/complexity.. hm..
