But what I found the most interesting was this blurb and clip from http://blog.wired.com/gadgets/2009/01/obamas-presiden.html
Of course there's tons of speculation surrounding his new limo. But here are educated and informed guesses from security experts that I believe are exactly right or probably under-estimat ed.
GM says the car occupies the "same footprint " as the current presidential ride, but it is a little taller and the windows a little bigger to improve visibility. Limo One is believed to weigh between seven and eight tons, and spy shots suggest it rides on a GM medium-duty truck chassis propelled by a diesel engine. The body is sheathed in military-grade armor as much as 8 inches thick on the doors (each of which weighs as much as the cabin door on a Boeing 747, Motor Authority says). The armor reportedly is a mix of dual-hardness steel, aluminum, titanium and ceramic. The windows are ballistic glass said to be 5 inches thick, and Dan Neil of the Los Angeles Times says there's probably a woven Kevlar mat covering the floorboard to protect the car from blasts. The cabin is believed to feature a sealed air recirculation system to protect its occupants from chemical attacks. Oh and the tires are also 5 inches thick as well.
