you can not bring in a g cab to the US past model year 2005. actually a few 2006 models can come in if production dates were 2005. the reason fo rthis is they are no crash tested past model year 2005. you need to buy them in europe, ship them here, then send them to a "lab" to convert emission to US standards. that last part will cost around $30k... if you want to buy one already here on the ground in the US figure $135-$165k for a lower mile example if its a 2005... earlier years and higher miles will be less.

What are the additional electronics? The NAV / Command system is fairly tested out at this point.

All the security and safety stuff with all those acronyms?! I thought they added a bunch of those things available in the GL to the G? I may be wrong...

G55K

I don't think they added much that hasn't been around for a little while. But, your point is valid. There's always some risk in buying a new generation/model.

Not in US/NA.

nyc123 has the right info about importing them to the US.

can anyone give me feedback on how the G63 maps / mapping software is? The one thing I loved about my 07 G55 navigation was the offroad tracking ( never get lost in unknown terrain ) and also the maps themselves had an amazing amount of forest roads / off road trails in the system.

DOes the 2013 still come with tracking feature?

thanks

Hi everyone. I recently traded in my G55 for a G63. I'm experiencing a throttle lag that is becoming more and more annoying. Essentially, I press the throttle and it takes a full second or more sometimes for the car to respond to the throttle.

I discussed this with my sales rep who explained that it is likely from the turbo chargers building up negative pressure (vs. the G55 supercharger). With such a high performance engine, this throttle lag and lack of immediate response is disappointing to say the least.

Was wondering if any of you have noticed or experienced this difference, and what - if anything - might be done about this.

Thanks.

I had a 55k before my 63, I know what you're talking about. I do think the rep is giving you the straight scoop but there is a fix. Flash the ECU and only drive in Sport mode. The added torque will give you that jump off the line response.

RBYCC

If your turbos are building up negative pressure then there is something really wrong.
A turbo, providing it has a free exhaust path builds positive until it reaches the preset pressure bleed off point.
At that point it relieves positive pressure.
But never should see negative or noticeable back pressure...

Turbos tend to have a bit of lag in spooling up as they are driven by exhaust pressure.
A properly sized turbo has no noticeable lag and should start building boost at low RPM.

Santino_MB

Thanks for the replies. The explanation you have given about positive pressure is essentially the one that I was given....meaning that the lag occurs as the turbos are building boost. Furthermore, I only drive in sport mode and am still experiencing this lag. I really enjoyed the G55's crisp throttle response, whereas my G63 is disappointingly sluggish due to this lag/delay.


So, I have the following questions:

1) How do you "flash the ECU," and is this something the dealership will do without voiding the warranty?

2) Are any of you with G63s experiencing this throttle lag?

Any other suggestions would be greatly appreciated, and thanks for the feedback thus far.

Behike

G63's turbo lag is lamentable. Flashing the ECU and driving it always on Sport Mode shouldn't be required. The G63 should be ready out of the factory. There is no such lag on the G55.

The turbo lag exists on models with the new 5.5TT engine. Same on the SL63.

Turbo engines suck big *****.

I wonder if that might also be caused by the transmission? I think that the 7speed might not be able to handle as much torque as the old 5 speed automatic. I wouldn't be surprised if the TCU was programmed to prevent excessive abuse.

RBYCC

The seven speed can handle power...it's in my CLK63 Black Series

Lag comes from the time it takes for the turbo to spool up.
Too large of a turbo and the more lag realized.
I would think that the G63 has properly sized turbos and should spool up under 2000 RPM with no real notice of lag.

I run twin Garrett T2's on my 1988 300CE M103-12V.
Starts spooling around 1700 rpm under power and no real lag.

Has the shake/wobble at 80km/hr and up issue been taken care of in the 63? I only have 35,000km on my '10 55!

Behike

I doubt it's the transmission. Like RBYCC said it's the turbos themselves. Whatever the reason, it's unacceptable. I hate turbo engines - Aggrh!! MB should have kept the 5.5K on the G55. The 5.5K + 5 speed auto make a perfect and indestructible combo.

gollard

Yeah, I think RBYCC made a very good point. However I thought I read something in the past the the 7speed gearbox can not handle as much Torque, however still high Horsepower. But then I haven't really been able to experience the 7sp in a newer AMG model. Maybe things got stronger or this was never true.

Personally in respect to the G63/G55 discussion, after long deliberation I just chose to go with a 2011 G55 vs a G63. I have been contemplating both for a few months now for a new truck to replace my 07. As much as I would love to get the extra power, my old G55 has been treating me so well, I just trust it too much and I simply don't know enough about the G63 in terms of longevity. But I am sure at the end of the day the G63 is going to be just as dependable - if not even more....

Behike

Now that I think about it, you're right, there was a mention of torque limit with the 7 speed transmission. I also have a 2010 G55 and I'm perfectly happy. I am not too found of the upgraded interior yet. I prefer the older and simpler one. I had a 63 on order but canceled. Either way, can't go wrong.

gollard

Yeah, both are so similar afterall. Personally I almost love almost everything about the G63, I actually think the re-design is pretty cool on the interior. I wish the pricing would stop going up :-)

I usually have an ipad / Iphone sitting in the same position as the new Nav screen is. But I normally navigate using google satellite maps, and it might be in the way for me in the G63.

In another G forum a member mentioned that when the W463 first came out everyone was worried about electronic gremlins and longevity issues, when the Benz updated in 2002, same worries etc. In the end every generation has held it promise of being a perfect Gelaendewagen...

The nannies in the G63 worry me a bit, and most importantly in terms of the mods I am planning on doing to my G55...a few other things as well, but knowing myself, within the next couple of years I won't be able to resist the call of the Bi-Turbo and experience that power.

gollard

I keep staring at you list of amazing cars, 71 280SL is on my bucket list, actually a couple of others as well

Thanks also for your input! If it can handle the Black Series, then the 7speed has to be pretty darn good! However what are your thoughts in terms of weight of the Gwagen and the torque the engines can produce?

I read that even in the E55s have torque management for the transmission. I imagine to prevent premature transmission failure. But then that might be a different transmission as well. Not sure

RBYCC

Thanks

The 722.9 7G auto trans is capable of handling the stock G63 output.
Weistec has modified the 7G to support 1000HP and about the same torque.

The stock 5G can handle about 40% more torque, but the 7G is better on gas mileage...like you really care in a G !!!

I prefer the G55K over the G63 mostly because I like the "outdated" interior and dash layout. G63 is too "country club' for me....

It's funny because looking back at this thread six years later, the 2012 G63 is now just an out-of-date G-Class while the G55 is arguably the last of the authentic, old-school Gs (original interior, side mirrors, no LEDs under headlights and best of all the 5.5 Kompressor engine).

Sure the G63 has a better ride and is clearly improved over the G55, but at the moment the G55 brings back more nostalgia, while the G63 is just the car that Kim K was driving two years ago.

simandang

Its funny that pretty much only YOU have that opinion.

BTW there was no 2012 G63
