As the name suggests, the Hummer H1 X3 is three times the size of a standard Hummer H1, making it the largest Hummer in the world, by far.
The Hummer H1 is one of the largest street-legal SUVs ever made, but it literally looks like a toy car next to the behemoth that is the Hummer H1 X3. Measuring 6.6 meters high, 14 meters long, and 6 meters wide (21.6 x 46 x 19.6 feet), this metal monster is the largest Hummer in existence, at least according to its owner, Sheikh Hamad bin Hamdan Al Nahyan, aka the Rainbow Sheikh, one of the most eccentric car owners in the world.
