Has Audi ever offered factory tint beyond the standard minimal windshield tint? Any different offerings in Europe (I'm in the U.S.)?

I really like the factory-optioned tint that Lexus offers on some of their SUV's. It's the greenish, somewhat reflective tint. Looks like it does a great job reflecting the heat/UV rays without making it too dark (for my taste at least). It'd be nice if Audi offered an upscale tinting option. Any info on the tint/manufacturer that Lexus uses? Thanks for any info.

Late'er,

 

I thought dealerships actually colored the glass instead of tinting it? The dealer could offer it but im sure its going to be A LOT of money since its the dealer... Id look around at different tint shops theres bound to be one with the tint you are looking for.

 

I've seen this specific, unique tint on quite a few Lexus SUV's and was therefore assuming it was a factory option. I thought I saw it listed as such on there website awhile back when doing a "build your..." Didn't remember exactly where I saw it or I'd have posted a link here.
