Specially built to withstand bombs, bullets and chemical attack, the car beached itself on the top of a ramp as it tried to exit the embassy during Barack Obama's one-day visit to Ireland.
The White House later said Obama and his wife, Michelle, were not in the vehicle at the time.
Crowds waiting outside the embassy for a glimpse of the First Couple cried "Oooh" upon hearing the crunch of heavy metal as the body of the car struck the ground between its front and back wheels. One man shouted: "Need a push?"
Specially built for Obama, the General Motors vehicle boasts its own oxygen supply in case of chemical attack, armor-plated doors, bullet-proof glass and reinforced tyres.
