Does this motor have a dedicated forum because it is troublesome or popular?
Just wondering how the M275 came to have a dedicated forum?
Does it have a lot of problems, or is it just a very popular platform?
Thanks

The fact that it has an almost cult-like following doesn't hurt either.

2004 W240 Maybach 57
Let's not forget that the M275 family is all derived from the M285 V12 TT which was developed for the W240 Maybach 57/62 line! When it came out in early 2004, the M285 was the most powerful production motor in the world. The M285 has higher boost/tune giving it higher HP/Torque #s than the base M275's. Then of course AMG took over tuning the M275 to produce their 65-series motors.

The M275 entered production in 2003. It was based off the ill-fated M137 which suffered from quality issues, including bore problems the cylinder block.
The M285 was an effort to get more power from the M275 and it was the basis for the AMG variant found in the 65s.

Instead of relying on Wikipedia with it's public access editing, I relied on my experience working at Mercedes when the M275 was released.
it's very likely the M285 development started alongside the M137 as a performance oriented variant. The two are quite similar.
It was clear early on that the M137, having even lower output than the outgoing M120, would not be capable of dragging around a lard-infested Maybach with anything resembling acceptable performance.
Other than the center sump oil pan the M275 found in the 57 and 62 are the exact same as the 220, 215, and 230 cars.
The 57S and 62S received the high output engines of the 65.

Much as I love a big car the 240 chassis Maybach is just too big and not sporting enough for my taste.
Once one drives a six liter AMG bent-12.... you’re hooked.

The M120 was also a 6 liter bent 12. It was a good engine (I have one for a roadster project) but it was no M275.
The M120 wants to zing and get all rev happy. The M275 wants to brute force its way through life.

Believe it or not, MB wanted everyone who touched a W240 to hold special certifications. Even the parts guys were supposed to be Maybach certified before they looked up parts. Few of us were. Most did it without certs. I did mine along with the SLR so we could show that someone in the store had the qualifications.

I put 120,000 miles on a '96 S-600. Loved it. The snarl of that naturally aspirated bent-12 was magic.
I'd still like to sample the AMG seven liter version of the 120.
I've put many miles on a 275 powered S-65 and now a 222 car with the 279. Love the progress made with each generation.
279 and the seven speed are great.
