I was trying to explain to a friend the difference between the G320 and the G55...
The best way I could compare the power differece was
"Imagine The G320 in Low Gear, then floor it!"

It makes me think, Does a G55 even need a low gear?
You would shred the tires before stopping the G55...

the G55 only needs low gears for off-road - if you don't go there, you don't need it.
Low range is there to create more torque in combination with lower speeds.

low range is also for control, correct? It's easier to control you speed or RPM when you in the low gear.

If i were short term towing of somethinge REALLY heavy... significantly more than it's rated for, i think i'd use the low range even in a G55k, because it significantly reduces the load on the gears... axles and drive shafts still take what you give it but much of the gear train "should" be getting a reduction in stress.

Harald has provided you with the technical/intellectual explanation... now let me tell you the practical one:

I also use low range for picking up my son from preparatory (private) school. The low range in my G, in combination with my (almost) free-flow air filter and my custom-made stainless steel exhaust scares the sh*t out of all those soccer moms in their X5s, Cayennes, Touaregs and Volvo SUVs when I enter into the school compound at full revs.... and my grin gets even bigger when I tell my son what all those poor (posh) people paid for their useless motors, compared with the 6 grand that I paid for my pride and joy.

I just love it! [:D][:D][:D]

Well, as the t-case of all the post-2001-Gs I've driven automatically shifts high-range over 40 km/h it wont be much of a show[:D][8D] Your son would also be late for school at such speeds[:D]

Erik is right - low range for towing is a wonderful thing. Thanks to the MB engineers this feature is available in all Mercedes with 4WD. Around town from traffic light to traffic light with a heavy load? No sweat. Low range is the answer. Why stress engine, torque converter and transmission with a 7000lb load?

Can't do it with a Jeep Grand Cherokee ("the pioneer in four-wheeling" - yeah right!) because their low range is part time 4WD and their high range is not even 4WD.

Guys Guys Guys....
Must everything be so literal? [:D][:D][:D]

It was just to give my friend an idea that it's more than double the HP. My G320 is 210HP and the G55 is 469HP. WOW! Since the low gears are 2:1, it would show the idea of double the HP (but with a very short range).

I personally don't recommend doing this. I don't think that it's good for the transmission, and don't think that the transmission could shift that fast either.

Chuck,

I have to disappoint you - horsepower does not change a bit.
http://4x4abc.com/jeep101/torque.html

In low range torque will increase by the factor 2.156 - HP will stay the same. By the way, torque moves your truck, not HP.
