Ford unveiled a new Explorer last year and the new Explorer is so much better looking that the old one and a much more capable off roader as well. Ford gave the new Explorer a terrain management system that allows the driver to set a control to the terrain rather than just having a couple modes for off road driving.
To show off how well that terrain management system works Ford has taken the Explorer on the road and put the thing on a massive teeter-totter to show off how well it can handle abrupt changes in terrain.
The teeter-totter is being used in Chicago at the Chicago Auto show, was made from steel, and is 30-feet long. It has an angle approaching 22-degrees that has the passengers looking at the roof of the building as the Explorer climbs. The hill decent control keeps the Explorer from slipping or flying down the steep hill on the other side.
