I'm not sure, but I'll venture a guess ... fuel consumption is
probably outrageous.

Either that or they cost a fortune to maintain.

Tony

Probably both.

Is that the Hummer® model???

I can't say for the H2 but the original Hummer with the diesel engine
isn't all that bad for a vehicle that size.

100 lbs thrust will be about 65 hp. Is this close to being a workable
rule of thumb?

Nope.

Power = Force x Velocity

For a "thrust" engine, the equivalent "power" it's producing will be
dependent upon how fast it's going. At 60 MPH, 100 LB of thrust is
equivalent to about 16 HP. At 150 HP, 100 LB of thrust is about 40 HP,
so you can see that a rule such as you postulate isn't going to work.

But generally thrust goes down as the engine accelerates. I believe
jet engines are rated at static thrust, only turbo props have a HP
rating.
