Avatar may have been a box-office king thanks in part to its wonderful use of 3D film-making. Hyundai, however, is not impressed by Mr. Cameron's science-fiction epic and it's decided to show-off the all-new Grandeur/Azera to the Korean public by way of a 4D commercial shown in theaters.
Hyundai wants those watching this clip to get the sensation that they're actually behind the wheel of the lux'd-up full-size sedan. While we can't get that feeling from watching a video on the internet, we can imagine where some well-placed mist and wind might show up to tantalize senses beyond just vision.
If you really want to try and recreate the 4D experience, have a friend on hand with a fan and a spray bottle then click past the jump to watch the clip. Thanks for the tip, Spark!
