WTH? This is the opposite of the normal type of scale modeling, a 3:1 scale-up of the already large Hummer H2..

A look inside the worlds largest Hummer

which is so big that its tires are taller than Shaquille O’Neal. Owned by a billionaire sheikh from Abu Dhabi the mammoth SUV needs four diesel engines to run, the cabin has a two storey apartment and only a crane can open its bonnet.

Eccentric show vehicles like this are a hobby of Sheikh Hamad Al Nahyan of Dubai, who has several such replicas. One I have seen is a 2:1:replica of an early 50s Dodge Power Wagon pickup. The original is an iconic vehicle in that part of the world for its ubiquitous use in early oil exploration.
I have a Dodge M-37, which is a military version of the 1954 Power Wagon. It is a lot of fun and surprisingly good on gas, a consequence of its modest engine power (96 bhp) and the complete absence of power-gobbling frivolities like power steering, automatic transmission, and air conditioning. I had the final drive changed so it could reach 70 mph without redlining the pushrod 6 engine.
