We've had the chance to sample Mercedes-Benz's so-called Magic Sky Control technology in both the SL and SLK roadsters, and it's a pretty clever party trick. The technology can turn the overhead roof panel in either of the two-seaters from transparent to opaque by energizing the light-blocking crystals sandwiched in the glass. By electrifying the crystals, they reorder themselves, varying the amount of light that's let through the glass roof panel.

We've seen similar electrochromic glass technology before in the Ferrari 575 Superamerica, but that appears to have been a one-and-done effort in Maranello, whereas Mercedes-Benz is reportedly keen to spread the technology around to more of its lineup. And not only are Benz engineers looking at more models, they're apparently shifting their focus to side glass – in particular, rear side glass. In fact, Benz's Viano Vision Diamond concept van debuted with the technology at this week's Beijing Motor Show. We can see Hollywood lining up already – this technology has real merit for keeping the paparazzi at bay.

But blocking out TMZ's long-lenses isn't the only issue – there's not-inconsiderable concern of law enforcement. Window tinting standards vary wildly from state to state here in the U.S., as well as country to country globally, something that could prove to be a major hurdle for the German automaker's legal team.

      It would be pretty cool if all of your windows blacked out when you set the alarm.

      Great idea, now we just have to wait for it to trickle down to the common man. Eliminates the worry for police that don't like approaching cars with tinted windows for safety reasons.

      Awesome! I wished there were pictures of it opaque and then see through or even video, the pictures in the gallery are not illuminating the technology at all. I remember a rich family in Europe who's front door had similar technology, sweet! I want that in my Z4 rear windows!

      Hi Chris, The technology used by Mercedes is based on Suspended Particle Technology, which is vastly superior to the electrochromic technology used by Ferrari. The Viano Pearl limited edition, slated for prodution in June, already uses Magic Sky control on the windows, so not sure how much of a hurdle this is really. 1809

      yet another technology started by Mercedes that we will no doubt see in regular cars in 10 years

      LOL...window tinting standards go out the window (pun intended) when the power goes off and the windows clear.

      This tech has been around for regular windows for something like 2 decades but nobody ever bought these because it's plain gimmicky.
