I had an interesting conversation with Tesla Service today. I am using Rial Lugano Gunmetals for my winter wheels, and had asked if they could change the in-dash image of my car to show the 21" Grey Turbines during my annual service, to be a closer match. I got the car back today, and it showed 19" Cyclones instead of 21" Turbines. The Service rep asked me if I saw the change, and then added that it was set to display Grey Cyclones. I asked if such a thing existed, or if it was just a combination of display option settings for wheel type, size and color. He said that they are showing an actual part number for Grey Cyclones, but they have not seen any in person yet, and they are not available for online purchase. I don't see it in the design studio, either. I thought this was very interesting. I really wish they offered a perfectly symmetrical 19" Turbine, in either color. I love how the Gunmetal grey looks with my Green. It also makes me curious as to whether HankLloydWright really saw a 19" Turbine pop up in the Design studio and then get immediately pulled (as discussed in another thread), and if so, if they really pulled it because the aerodynamics were worse than the 21" Turbine. Still, Grey Cyclones might be something to consider.
