Sumo vs. Terminator - FJ vs. H3
Both Toyota FJ Cruiser and Hummer H3 are SUVs that can do anything. Design should be the least important thing, but it isn't so.
To my opinion, FJ is more aesthetically fun but Hummer has its unique advantages, one of which would be a "MTV rapper" feeling driver has when entering the driver's seat and Terminator feel when on the road.
On the other side, FJ turns into a sumo wrestler, more capable on more than one account.
Both cars are very comfortable, high drivers position ensures excellent front visibility, huge rear view mirrors help driving backwards. Large spare wheels dominate the backs of both cars.
Hummer's interior is far more luxurious than FJ's which is rather spartan. H3 is full of black leather and "titanium look" applications = overall, driver has a feeling that he's driving in the tycoon's office. Plus, Hummer is more spacious inside, especially at the back seats.

On the other hand, FJ has higher roof and therefore, more headroom. Its storage capacity is 1891l, which is 314l more than Hummer's.
H3's 3,7l 244bhp engine has an advanced alternator which should provide a better fuel economy. But, despite the technical tricks, H3 will burn 16l on average compared to FJ's 14l.
Clearly, none of the competitors will ever be a Greenpeace official car.
Toyota's 249bhp engine has similar characteristics to H3, but it's far more refined. Its 6 cylinder engine is faster and less noisy than 290kg heavier Hummer's engine. Plus, Cruiser has a modern 6 gear automatic transmission - Hummer's old 4 gear transmission loses another point here.
Toyota has a towing capacity of 2268kg which is 227kg more than H3. That's when US towing capacity standards are used - in Europe, difference is even bigger (2800kg Toyota, 2041kg Hummer).
When driven off road, FJ proves better, mostly because higher clearance (235mm) and very efficient traction control system.
To conclude, if you drive the American way and have extra 10.00USD to spend, then go after a Hummer.
More agile FJ Cruiser is better option for everybody else.
