In addition, the premium interior has the ambient led lighting in the footwells and under the door panels and the Alcantara on the upper surface of the dash.
The standard interior would not have the led lighting nor the Alcantara on the dash.
Todd is totally correct. Other than those two things the door panels would be in a imitation leather and
the large panels under the dash would also be in imitation leather as would be the airbag cover on the center of the steering wheel.
Not sure if the steering wheel rim cover is leather in the Premium Interior Package?? I know the airbag cover is leather in that option. Anyone know??
As a historical note, the led lighting was once (prior to Oct of 2014 or sometime around then) a stand alone option and not part of the premium interior package. Additionally, the parking sensors were once a stand alone option as well, but were rolled into the Tech Package. Also around
the December 2014 time frame it was rumored that the heated steering wheel was added to the Cold Weather Package, it became solidified
in January 2015 Design Center option description. There was a lot of teeth gnashing on the P85D order thread regarding this.
Also a thread titled "Will I Get My Hands on a Heated Steering Wheel". Also around that time, the Yacht Flooring left the option status and became standard equipment. These options are always in a state of flux since I have been Tesla shopping. Fun Stuff.
I am not sure the motive there by TM is profit, but rather offering a more luxurious feel to the interior to those who desire it.
I am sure TM's cost for this option is less than the asking price.
