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.

This giant Hummer is powered by four diesel engines, but the technical specifications, such as top speed, torque, and the like, have not been made public yet. In fact, the very existence of the vehicle only became known recently, after photos of it being driven to the Off-Road History Museum in Al Madam, UAE went viral online.

The Hummer H1 X3 is just one of the exotic cars in the Rainbow Sheikh’s collection. Apart from owning the largest collection of SUVs and the largest motorized model car, he also owns the world’s largest SUV, which also happens to be one of the strangest-looking vehicles ever made.
