Can anyone confirm new engine 5.5 biturbo??

[michal12]

Saw rumours elsewhere that the G55 could get the latest AMG engine, the new direct injection twin turbo V8 5.5 which can either be had as 544hp or 571hp. That would be seriously nice. Also, a new 7 speed gearbox would do a lot. Hope that wuld push 0-60 time deeply below 5 second mark. I think they really should do it as the G55 should maintain its cult status also by being the most powerful beast. Any X5M or Cayenne has now 555 or so horses so a power upgrade is needed.

Maybe for the 2012MY, but nothing confirmed yet.

LOL...although it's debatable whether any SUV on the planet "needs" a power upgrade when it's already making 475HP+, one can get to 550HP and beyond relatively easily w/the G55's SC engine through only a few aftermarket upgrades. That path is well worn and proven.

Current US model is rated at 500 hp.

Rumors, no confirmation. If you're after the highest amount of hp and torque, you can add ~100 hp and ~100 to the current 5.5 SC engine with a simple ECU flash and pulley for about 2500$.

The current 5 speed auto has been, is and will forever be indestructible and can host over 1000 ft/pd of torque. Not sure what the 7 speed would bring more. Better fuel economy? Forget about it.

With all due respect, you truly underestimate the G-class and especially the G55. It doesn't need to have more hp, torque and a better 0-60 than anything else to be special. The vehicle's history makes it unique. If you want to beat X5M, X6M, Cayennes and what not, you're looking for a sport SUV. The G-class is not it. I'd take the G55 over anything else even if it had 100hp/torque with a 0-60 of 10 seconds.

The ML63 would be the only MB candidate in such competition. To end, I'd take the G55 over anything else even if it had 100hp/torque with a 0-60 of 10 seconds.

Indeed. 475HP+ means anything over 475HP...

[adam28]

The G-55 is built like a tank, and can go over a lot different terrains that the Porsche or XM5 couldn't.

A better comparable to the XM5 would be the ML63.

The G Wagen is not a sporty SUV, but the G55 is a fun toy, without questions. It has its place, and that place is lifting the front tires off the ground with a full 700 hp tuned 5.5L!!

I understand there is history in the G. I do not care. It is history not heritage, so..
I like the G55 bad-*** attitude and 'above it all' arogance. Would I consider the G350 diesel? No. So definitely large part of the G55 appeal is its ridiculous engine. It had 476hp back in 2005 when BMW X5 had 367hp...

I can understand the constant need for more hp but my point in general was that the G55 is still, imo, above them all because of the way it looks and its history/heritage.

[g55lover]

I had a 2005 G55 and can't imagine the need for additional hp or torque. The X5M is nice but isn't equal to the G even at its much lower price point.

I'll co-sign on the above comment This is a rhetorical question, but do we need a bi-turbo on such a high profile vehicle? This unit catches enough wind as it is, so why add more power?

yea it's called the m172 engine. it comes out this summer for the s class and the cl class cars. and i'm definately not going to argue with any of you guys about cars because your big G55's will flatten my little c55.lol
