GL450 underpowered?
The last thing I can imagine myself doing is launching it. Yes it's fast no doubt, but.. why.. It just feels like *SO MUCH* is being stressed/torqued when you hit the gas hard on these, I'd try to stay away from the MB parts desk by being soft on this one.. This isn't the type of vehicle for that type of driving..

I'd have *DESTROYED* my wallet with that..
I can totally imagine what would have happened to me ..
RWD forever.

Driven both 450 and 550 on the 164 platform, I can tell 550 is a bit more peppy at the launch but 450 is no slouch either, also when you are down to sea level you will have a noticeable difference, they both feel much more alive. Being in CO sucks, especially going to higher altitude.
The Mercedes automatic has seven speeds for fuel economy reasons. The first couple gears are pretty short and you won't wind out to any particular speed.
You're looking for something the car wasn't designed to be. The top speed your GL450 can achieve proves it's not underpowered, as aerodynamic drag increases with the square of speed and it will require plenty power to pull the top speed your vehicle can achieve.
The next generation GL, the X166, has an AMG version. AMG engine, AMG tuned transmission. Your fantasy vehicle, perhaps?
I have a 2010 GL450. It’s a 4.7l v8 with 335 hp and 339 pound feet of torque. I always felt the car was underpowered for a v8 benz. For instance when I floor it from a stop the RPM shoot up before they shift and the engine sounds stressed. When its in there 3rd gear around 30mph then it feels better when I floor it, but do you guys think this SUV is underpowered? Does making the RPM’s shoot up to 4-5k from a stop bad for the engine? I often like flooring it.
Yes, it puts extra stress on the entire system. Fuel pressures rise to pretty much max the system can deliver, coolant pressures shoot straight up because of the increase in RPMs, everything is “asked” to deliver its full output right off the start.
Now if the vehicle is only a few years old, this isn’t so much of an issue, but as it ages, seals, hoses, fittings, clamps, etc., all loose their original integrity and fail. Could mean a coolant hose that has been fine at lower rpm’s, will now split open when you “floor it”.
The whole “Italian Tune Up” (by revving the **** out of an engine) is 1980s thinking. You can’t flow more fuel over the valves and blow out carbon on a modern engine. Just the increase in airflow (by revving it) is not enough to do anything for carbon. Even soaking an engine doesn’t remove all the carbon, you think a few redline pulls would do it??
Bottom line, these are big family SUVs, they are not going to be fast, they are going to be comfortable and looking good doing it. My diesel has lots of jamb for a big SUV.
