Barack Obama's limousine

Since Barack Obama is the president of the United States of America, we must protect him because he is constantly in danger. To be safe, Général Motors made a Cadillac that has several characteristics. The car looks like a tank. The vehicle weighs eight tons and the doors are 20 centimeters thick! The car nickname the "Beast"  would have a 500 horses power. If attacked, the president would have a reserve of oxygen in case he should remain long in the limousine. He has a mobile office to work. The tires are Kevlar reinforced and the vehicle can continue to move forward even if the tires are slashed. There are cannons of tear-gas. The limousine measures 5.49 meters long and 7.78 meters height. Other information are kept secret for the president's safety. I initially said the car looked like a tank, we still wonder why?
